How to add oil to trimmer gasoline

Which oil to choose

For effective trimmer operation, it is necessary to select oil for two-stroke engines. This is due to the lack of an oil sump in such a device. Depending on the chemical composition of the oil, the following classification is distinguished:

  • mineral. based on petroleum distillate, suitable for low-power and air-cooled equipment, but requires frequent replacement and can only be used in good weather during the warm season;
  • semi-synthetic. suitable for garden equipment with air and liquid cooling;
  • synthetic. based on esters, do not require frequent replacement and can be used at any time of the year.

Oil for 2-stroke engines is characterized by good solubility and complete combustion feature. It is recommended to use a lubricant for the trimmer that is suitable for air-cooled units. Most often, it is indicated on the packaging that the oil is intended for garden equipment and is marked TA, TB or TC. over, the last of them is the most preferable.

If the consumption of engine oil during the summer season is planned to be large due to the presence of a chainsaw, brush cutter, lawn mower in the garden arsenal, then it is advisable to buy 5 liters of oil at a more favorable price. If it is needed only to mix with gasoline and fill the only tool, then 1 liter will be enough.

Often, manufacturers of benzokos produce the right oil, so you can make your choice easier if you select a fluid of the appropriate brand.

The choice of oil and gasoline for preparing a fuel mixture for a trimmer: dilution ratio table

A trimmer, or a petrol cutter, is an indispensable tool in the household. over, its reliability, efficiency and long service life depend on many factors. For example, the quality of fuel. This means that you need to select the right trimmer oil, observe the proportions when added to gasoline and the rules for refueling the device.

trimmer, gasoline

What gasoline to fill

Gasoline for the trimmer should be chosen unleaded with a stroke number of 92 or 95. As practice shows, AI-80 gasoline can lead to device breakdowns, which is a questionable economy.

Fuel must be fresh, that is, after purchase, it can be stored for no more than 60 days.

Other factors also affect the quality of the fuel, for example, the use of a special lubricant for brushcutters and dilution in a separate container. It is also recommended to use special canisters designed for storing gasoline.

How to dilute gasoline with trimmer oil

Dilute the trimmer gasoline in the correct proportion. An insufficient amount of oil can lead to poor lubrication of the brushcutter elements, which contributes to rapid wear. If the oil is more than the prescribed amount, carbon deposits will form on the pistons and spark plugs. Carbon deposits on the moving parts of the engine interfere with normal operation and lead to early engine damage.

What proportion is required for a particular trimmer model can be found in the attached instructions. Most often, for 2-stroke gasoline engines of mowers, a fuel mixture is used in a ratio of 50: 1, where 50 is part of gasoline, 1 is part of oil. That is, 20 ml of oil should be added to 1 liter of gasoline. The table will help you choose the required ratio.

To correctly measure the proportions, use measuring containers with a milliliter scale. For these purposes, a special double-necked canister is perfect; it is designed for mixing and storing oil gasoline. For example, oil can be drawn with a medical syringe without a needle. Before mixing liquids, make sure that the container for the ready-made fuel mixture is free of water, dust and dirt particles.

It is unacceptable to dilute gasoline with lubricant directly in the fuel tank; moreover, the proportion of oil and gasoline must be strictly observed. If you ignore this rule, then the trimmer motor can be unstable, due to which it will quickly fail.

It is not recommended to use plastic bottles or canisters for this purpose. This is due to the fact that gasoline tends to dissolve plastic, which means that some of the plastic can get into the fuel tank, which can lead to a breakdown of the carburetor. Although there are special plastic canisters labeled “flame”.

This will require:

  • petrol;
  • oil suitable for air-cooled two-stroke engines;
  • canister, preferably metal;
  • mixing container, metal is also better;
  • gloves;
  • respirator.

In addition to protective equipment, do not forget about fire safety rules, because gasoline and engine oil are flammable:

  • it is better to carry out work outdoors in order to avoid the accumulation of gasoline vapors in the room;
  • do not smoke and create situations associated with the occurrence of a spark.

Make a mixture of gasoline and oil as follows:

  • Pour 1 liter of gasoline into a container, add half of the required portion of oil. Mix thoroughly, do it with extreme caution, away from sources of open fire.
  • Add the rest of the oil to the trimmer gasoline and mix thoroughly again. Fuel can now be poured into the trimmer fuel tank.

The mixture can be stored for no more than three months, so it is better to dilute gasoline in such an amount that it is enough for several uses.

How and how much to refuel

Filling the trimmer fuel tank is easy. To do this, place the tank so that the lid is on top. The amount of fuel depends on the trimmer model. This information is indicated in the instructions, there is also a mark directly on the tank.

It is strictly forbidden to overfill the tank.

Doing so can cause fuel to overflow into the intake manifold and fuel filter, which could cause engine damage or fuel ignition.

When refueling the trimmer, you must follow the safety measures:

  • try to fill in the liquid so that it does not spill, you can use a watering can for this;
  • if gasoline still spills, then it must be wiped up immediately;
  • the start of the trimmer must be started after the container with fuel is removed to a safe and secure place, preferably at a distance of more than 10 meters;
  • when there is a long break between operations, drain the remaining fuel.

Correct proportion and adherence to mixing and filling techniques will help to extend the life of the trimmer. In this case, it is recommended to choose only a quality product of the corresponding brand.

Oil selection and fuel mixture for petrol cutters

So, have you finally become the owner of a petrol brushcutter or lawn mower? And your imagination is already creating images of how you courageously cope with the dense grass. However, the dream of a “perfect lawn” remains a dream, when the question involuntarily arises: what oil to use and what are the proportions of mixing it with gasoline?

You can find a lot of information on the correct preparation of the fuel mixture on the Internet. This topic is actively discussed on forums and other thematic resources. But, despite such an active discussion, there are many inconsistencies that have to be dealt with.

It doesn’t really matter what technique is used, it could be a lawn mower. brushcutter or chain saw. they are united by one. two-stroke gasoline engine. Unlike the 4T, it does not have an oil sump. To feed it, it is required to prepare a special fuel mixture consisting of gasoline and oil. The resulting liquid is fed directly to the engine (carburetor). During use, all actively working parts are thoroughly lubricated, contributing to trouble-free operation under all operating conditions.

Lawn Mower Engine Oil

Depending on the chemical composition, lubricants are divided into the following main groups:

Mineral. They are made on the basis of oils obtained from petroleum distillates. They are characterized by high viscosity and require frequent replacement. The material is intended for low power appliances with an air cooling system. Recommended for warm weather.

Semi-synthetic. They represent a kind of “golden mean”. They are based on a mixture of mineral and synthetic oils. A similar lubricant can be used in 2T and 4T engines, gardening and other equipment with air and liquid cooling.

Synthetic. They are made on the basis of special synthetic components containing esters. They are characterized by low viscosity and long service life. They can be used all year round, regardless of temperature conditions. Ideal for challenging heavy duty equipment with constant variable performance.

Any two-stroke oil, due to its 20% solvent composition, mixes well with fuel and has the feature of complete combustion. Their second characteristic is their color, which can be green, red or blue. Of course, this does not mean that some lubricant is better, and some is worse. This is done solely so that it is convenient for the user to distinguish oil from pure gasoline.

Classification of engine oils:

The required parameters of oils for 2T engines are prescribed in the requirements of API TC JASO FC, API TC JASO FC ISO GD and API TC JASO FC E-GC. The most widely used classification systems are API. Based on this, 2T engine oils are divided into 4 large groups:

TA. suitable for household appliances with an air cooling system and an engine volume of no more than 50 cm3.

TB. used for more powerful equipment with an air cooling system and a motor volume of 50.200 cm3.

TC. used in technology with high demands for oil quality. It is a high quality lubricant for 50.200 cc two-stroke engines. Great for lawn mowers, brushcutters, trimmers, chain saws and other garden equipment.

TD. for outboard boat motors with liquid cooling.

Most suitable material for 2T motors of API-TB and API-TC class. However, it is necessary to refer directly to the product passport, where the manufacturer indicates the brand of engine oil recommended for its equipment.

Important! For brushcutters, lawn mowers and other 2T gardening devices, a special engine oil is provided for two-stroke engines with an air cooling system and marked “for gardening equipment”. Do not use lubricant for 2T engines with liquid cooling system. Also not recommended oil for outboard engines, motorcycles and other equipment.

Oil to gasoline ratio for brushcutters: why accuracy is so important?

All of us in childhood loved to “chew”, so the process of preparing a fuel mixture is not only simple, but also interesting. First of all, it is worth considering the fact that the proportions of the mixture may be different. This depends on engine configuration, oil markings and manufacturer recommendations. The fact is that with an insufficient amount of lubrication, the cylinder and piston heat up, which leads to shallow scuffing of all rubbing surfaces and, consequently, to the failure of the cylinder. piston group. Well, in case of its excess, on the contrary, we get coking of the piston ring and the formation of a large amount of carbon deposits.

And even despite the fact that there is a generally accepted mixing ratio of 2% (for every liter of gasoline, 20 ml of lubricant). The proportions in the mixture are still recommended to be kept exactly.

How much to pour oil into gasoline for petrol cutters?

Everything is quite simple, with the correct balance, the engine runs at full capacity, all parts are thoroughly lubricated and do not wear out. As a result, we get a confidently working technique that will last more than one season.

To know how much oil to add to the brushcutter, you need to familiarize yourself with the performance characteristics of the product. Proportional ratios can be presented as follows: 1:25, 1:40 and 1:50, which means 1 part of oil for 25, 40 or 50 parts of gasoline.

1 liter of gasoline = 1000 ml

To determine the required amount of oil for a ratio of 1:25, you need 1000/25 and we will get a ratio of 40 ml.

We carry out the same actions for the ratio 1:40 and 1:50:

1:40 (for 1 liter of gasoline 25 ml of oil)
1:50 (for 1 liter of gasoline 20 ml of oil)

To ensure that the proportion of oil for petrol cutters is observed correctly, it is recommended to use a special measuring container (not plastic). Eliminate the possibility of dirt and water getting into the fuel mixture. this may affect its quality. It is better to start preparing the mixture with gasoline. Pour it up to the required mark, then add oil. A couple of tilts of the container are sufficient for mixing. The liquid quickly combines and acquires a uniform hue, which, depending on the structure of the oil, can be red, green, blue or other. After that, a properly prepared mixture is poured into the equipment fuel tank.

Before using the equipment, make sure that the tank cap is tightly closed. If you get more fuel, then the remainder can be stored in a special canister or mixing container (no more than 14 days). It is recommended to drain the unused fuel.

Important! Be sure to follow the safety instructions. Mix fluids outdoors to prevent corrosive gasoline fumes from accumulating indoors. Wear gloves and long sleeves. Do not smoke or set anything on fire.

Petrol

RON 92 gasoline is considered the most popular type of fuel for two-stroke engines. Due to its relatively low cost, it is extremely rarely falsified. Therefore, not one hundred percent, but you can be sure of its quality. It is also permissible to use AI-95 fuel.

As for the storage of fuel, its period should not exceed 3 months. Over time, gasoline loses its properties, the resin becomes higher and a polymerization process occurs, which adversely affects the combustion chamber. The fuel mixture for petrol mowers, made from low-quality materials, settles in the form of carbon deposits, as a result of which the main components and systems of the engine suffer.

Recommendations for use and storage

The fuel is ready, poured into the fuel tank, the first spurt and the long-awaited start. However, if you want the equipment to work as long as possible, it is recommended to run it in for the first time. To avoid overheating of the engine, it is recommended to adhere to the average load. After the main elements of the system have been thoroughly lubricated, the load can be increased.

Certain rules should also be followed when preparing the braid for off-season storage:

Drain the remaining fuel from the fuel tank and carry out the final run until the fuel is completely depleted. Then, pause the work and make sure that the engine is completely cool.

Unscrew the spark plug carefully and add about 5 ml of lubricant. Pull the starter handle slowly to distribute the oil equally evenly inside the engine. Then, return the candle to its original state. Store equipment in a cool dry place.

Outcomes

Rules for pouring the mixture into different engines

All of the above is relevant for two-stroke engines. In the case of four-stroke engines, nothing needs to be diluted and mixed. gasoline is poured into the fuel tank, and oil into the crankcase. It is important to know that oil intended for a four-stroke engine or for a liquid cooling system cannot be added to a brushcutter with a two-stroke engine. Otherwise, the entire piston system will be disabled or severe overheating will occur.

Important! For the first filling of a four-stroke engine, no more than 90 ml of oil can be poured into a special tank.

Mixture storage rules

The remaining unused fuel mixture needs a dark, dry area where it can stay for up to 2 months. In general, there are different expert opinions on this matter:

  • for mineral oils, the shelf life is 7-10 days, after which their lubricating properties are lost;
  • for semi-synthetic and synthetic brands, there is evidence that they are stored from 30 days to 2 months.

After a longer period of time, it is recommended to change the fuel to a fresher and newer one.

So, above was described in detail the process of how to properly dilute the gas mixture for two-stroke brushcutter engines. To avoid damage to the trimmer as a result of insufficient oil or frequent cleaning and unstable operation due to excess lubricant, you should carefully read the operating instructions for the brushcutter and follow it scrupulously.

Features of refueling brushcutters

Depending on the design of the engine, brushcutters are divided into two-stroke and four-stroke. In the first case, the piston in an internal combustion engine makes 2 strokes in one working cycle, and in the second case. 4 strokes. Differences in the principle of operation of the engine also cause different approaches to refueling the trimmer.

Refueling a brushcutter with a four-stroke engine

Four-stroke engines are used in professional brushcutters. They have great power and can work for a long time without interruption and refueling. They also use gasoline and oil as fuel, but they are poured into different tanks. This means that the oil does not participate in the combustion process, therefore the exhaust gases are not so toxic.

On a note! Along with better environmental performance and the ability to heat less, four-stroke brushcutter engines are also more economical. They consume much less fuel. savings up to 50% for gasoline and up to 80% for oil.

How to properly dilute gasoline for a trimmer

Depending on the type of trimmer, they can be filled with a fuel mixture or separately with gasoline and oil. Now there is a huge variety of types of motor oils that are suitable for various equipment, including gardening. To choose the right fuel for a particular brushcutter model, you need to know its technical features and understand the brands of gasoline, as well as liquid lubricants. All the details on how to dilute gasoline with trimmer oil are in the material below.

Gasoline selection rules

Before buying fuel for your brushcutter, you need to read the manufacturer’s instructions. It lists the grades and grades of fuel that can be used for a particular trimmer model. In general, when choosing gasoline, you need to focus on the A-92 brand. A-95 is also suitable for refueling brushcutters, although some experts do not recommend taking fuel with such an octane number. This is due to the fact that at many gas stations in Russia, such gasoline contains various additives and solvents (for example, alcohol). It should be borne in mind that you cannot save in this matter. in order to extend the service life of the brushcutter, you should choose only high-quality fuel from trusted suppliers.

Refueling a brushcutter with a two-stroke engine

In ordinary household models, the brushcutter, as a rule, uses a two-stroke engine. The petrol cutter does not need a lot of power and agility, so it is quite suitable for the tasks assigned. In addition, this engine is much cheaper and simpler, but it is fueled with a mixture of oil and gasoline. Such fuel is poured into the carburetor and fed into the cylinder in the form of oil-gasoline mist. Thus, the oil provides lubrication of all the necessary parts, and in the process of engine operation, it burns out along with gasoline. However, the combustion of this mixture is accompanied by the release of a pungent odor and smoke, which increases the toxicity of exhaust gases.

Important! For such brushcutters, you need to use a special oil for two-stroke engines, which completely burns out without leaving a burn, and has a low evaporation rate. And so that it mixes well with gasoline, it contains 20% solvent.

Oil selection rules

Engine oil, depending on the chemical composition, is:

  • mineral. made from petroleum distillates and intended for low-power air-cooled equipment;
  • semi-synthetic. is a mixture of mineral and synthetic oils and is suitable for 2T and 4T, as well as for air and liquid cooling;
  • synthetic. made on the basis of esters and can be used in powerful technology, as well as for work in difficult climatic conditions.

Important! Oils for two-stroke and four-stroke engines differ in their ability to dissolve, burn and evaporate. At the same time, in order for the liquid lubricant to differ from gasoline, it is painted in different colors: blue, green, red.

Depending on the API classification, the following groups of oils for trimmer motors can be distinguished:

  • TA. for low-power equipment with an engine volume of up to 50 cm³ and air cooling;
  • TV. for powerful equipment with a motor volume of 50-200 cm³ and an air cooling system;
  • TS. for powerful two-stroke equipment (brushcutters, chainsaws, lawn mowers, etc.) with an engine volume of 50-200 cm³;
  • TD. for engines of boats with liquid cooling.

To select the optimal oil for a particular trimmer model, it is better to take into account the recommendations specified in the instructions. For brushcutters 2T, oil of API-TB and API-TC class is usually used.

On a note! In addition, there is a JASO classification for two-stroke engines, and SAE30 is still used for four-stroke engines.

Leading garden equipment manufacturers develop and produce oils for their equipment themselves. Such lubricating compositions most fully satisfy all the technical and operational characteristics of a specific series of trimmers. For example, for Stihl (Calm) FS 5 brushcutters, it is best to use Stihl HP or Stihl HP SUPER oil, for Husqvarna 143R, Husqvarna HP or Husqvarna LS oil is suitable. But for the Patriot brand, ordinary mineral oil M-8V is also suitable.

How to choose for a petrol cutter?

For two-stroke engines, brushcutters use AI-92 or AI-95 gasoline. Most often. the first of the named. There is always information about this in the technical data sheet of the product. If, for some reason, it is not known exactly on what gasoline the trimmer should work, you can pick it up by testing both brands of gasoline in action. Global changes in the engine will not happen from this, and it is quite possible to determine what kind of gasoline this or that model of the unit “likes” more, according to some factors. This will be shown by the developed power, and throttle response, and engine heating, as well as its stable operation at all speeds.

But it is much more difficult to determine the proportions of oil to a certain volume of gasoline. In this case, you need to know at least something about the manufacturer of the equipment. And already according to the standard proportions for this manufacturer, select the proportion for a specific model, taking into account the type of oil.

You can start selection even by country of origin.

For example, for Chinese low-power trimmers, two ratios are mainly used. 1: 25 or 1: 32. The first is for mineral oils, and the second is for synthetic oils. We have already talked about the choice of standard proportions for petrol cutters of European and American manufacturers in connection with the type of oil. According to the class of oils for household trimmers, it is necessary to use TB oil according to the API classification. For more powerful. vehicle class.

For information on the ratio of gasoline and oil necessary for a petrol cutter, see the next video.

Today, buying a trimmer is not a problem for yourself. It occurs on mowing if the mower has not prepared the fuel mixture correctly. The motor often stalls unexpectedly, like a blowtorch. We have to start the engine over and over again, pulling the semi-automatic winding device, popularly nicknamed the “lash”.

Consequences of violation of the ratio

The service life of the motor scooter depends on how accurately you follow the manufacturer’s recommended oil-gasoline ratio. The fact is that the fuel mixture enters the cylinders in the form of gasoline-oil mist. And the task of the oil composition is to lubricate the moving and rubbing parts and surfaces of various parts in the cylinder. If it suddenly turns out that there is not enough oil, and somewhere it will not be enough at all, the parts that touch dry will begin to damage each other. As a result, scuffs, scratches and chips are formed, which will certainly lead to complete or partial engine failure (for example, it can jam).

In the opposite case, when too much oil enters the engine, it does not have time to completely burn out, settling on the cylinder walls and turning over time into solid particles. coke, slag and the like. As you might guess, this also leads to engine failure. The most important thing is that you must not allow even a single violation of the proportion in the direction of a lack of oil. It is better to pour a little oil 10 times than not to top up just 1 time. It often happens that this time is quite enough to break the engine.

Algorithm of actions

Fuel quality increases with proper mixing of the mixture components. The question arises before the mowing machine, how to breed, in what sequence. When mixing the components, pay attention to whether the containers are cleanly washed. A tiny slurry can stall the fuel supply to the carburetor. The fuel tank should be filled from a special container with a filter device.

The procedure is as follows. Half of the available gasoline is mixed with the volume of the specified amount of lubricant. This is followed by the mixing process.

When the components acquire a homogeneous consistency, 50% of the remaining fuel is poured into the partially diluted gasoline. This is how it is recommended to dilute the trimmer fuel.

Choosing a brand of gasoline for trimmers

It is necessary to select the brand of gasoline for mowers taking into account the manufacturer’s recommendations. If you do not follow them, then the motor will soon break down. Often RON 92 or RON 95 unleaded fuel is used to fill the trimmer tank.

Gasoline for fuel mixture

Filling the trimmer with AI-80 gasoline can lead to device breakdowns due to its low technical characteristics. Please note that after purchase, fuel can be stored for no more than 60 days, but it is better to reduce this period.

Polyethylene cans are not used for storage, since static electricity will be generated in contact with the inner walls. An accidental spark will cause an explosion. Although, there are special plastic canisters marked “flame”.

How to choose the right proportion?

The petrol cutter is filled with A-92 gasoline. There are other factory instructions that require gasoline of a different octane number. For example, A-95. The difference in cost is minimal.

The selection of oil does not take liberties. For two-stroke engines, the API sets a specific order:

  • for motoblocks, brushcutters, air-cooled mopeds. TA class;
  • engines with a cylinder volume of 200 cm³. TB class oil;
  • recommends the use of TC class oils for all-terrain vehicles and motorcycles;
  • yacht engines, hydro scooters, motor boats use TD brand lubricant.

From the above list, engine lubricating fluid of the last two positions is not recommended for use with trimmer power units. Letter designations indicate from which petroleum products the lubricating fluid is made.

Attention: If you buy a product on liquid domestic trading floors, take an interest in the labels on the container. The English words self mix say that self-mixing with gasoline is not required. If there is a pre mix phrase on the label, you should prepare the combustible mixture yourself.

Types of brushcutters

Today, on liquid specialized trading floors, there is a large selection of mechanisms for mowing grass and small bushes. For example, lawn mowers are offered with an electric motor, with gasoline power plants. Brushcutters equipped with diesel motors are not produced, since they are slow-speed.

Liquid statistics show the advantage of brushcutters with internal combustion engines over electric counterparts. Electrokos is used in places where there is a stationary electrical network.

Selection Tips

Now let’s try to figure out how to choose a quality gasoline trimmer oil. The main feature to look out for is the base number. This moment excludes the oxidation of parts in which friction is observed, and slows down their deformation as much as possible. The more this compound is used, the faster it loses its alkalinity and becomes more oxidized. The optimal indicator of acidity (PH) is a value of at least 8-9 units.

The second important factor, which also has a serious impact on the performance of a gasoline trimmer, is the viscosity of the oil. This characteristic determines the ability to use the device at different temperatures. Summer brands of oils begin to thicken already with a minimal decrease in temperature.

But given that such trimmers are usually used in autumn and spring, it is best to use just oil with summer markings.

The third point, the importance of which should not be underestimated, is the flash point. This indicator should not be less than 225 degrees. Otherwise, the composition will burn out very quickly and the load on the piston group will begin to increase, which will cause its accelerated wear. Also, 4-stroke oil is not suitable for 2-stroke. Namely, the latter type of motors is used in the vast majority of gas mowers.

If we talk about manufacturers, then you can make a small rating that will allow you to navigate the formulations offered by various manufacturers. For example, Stihl offers quality synthetic and mineral oils, which have already proven themselves as an excellent solution at any time of the year.

Shell Helix Ultra oil is considered very good. Experts note its high characteristics and excellent indicators of alkalinity and viscosity. In addition, the products of such brands as Oleo Mac, Motul, Hammerflex, Echo are considered worthy. If we talk about the products of domestic brands, then you should pay attention to Lukoil oil. Its price is several times lower than foreign counterparts, but at the same time it has high quality and good technical characteristics.

In general, the ideal solution would be a synthetic or semi-synthetic oil labeled TB or TA.

Varieties

The oil that is poured into the engine may differ in the production method. According to this criterion, it happens:

  • mineral. this type is obtained during the processing of petroleum products;
  • synthetic. it is obtained by processing or synthesizing gas;
  • semi-synthetic. this type has better characteristics due to the introduction of synthetic-based components into it.

Oil for petrol cutters refers to compositions intended for use in air-cooled engines, which have a combustion chamber volume of 50-200 cubic centimeters. In addition, any two-stroke oil can differ from analogs in additives that give it certain additional characteristics. They are of the following types.

  • Antiwear. The main task of the oil will be to reduce wear of parts during the operation of the device.
  • Antioxidant. They do not allow oxidation to occur and make it possible to maintain the performance of the oil for a long time.
  • Anti-corrosion. Their task is to prevent corrosion from forming on the engine parts.
  • Friction modifiers. These additives can significantly reduce the coefficient of friction.

Two-stroke oil from different manufacturers may differ in the combination of additives used, which means that their properties will differ.

Recently, when purchasing oil for dilution with gasoline, users very often come across the fact that special letter abbreviations are applied to the cans. These designations are made within the framework of the API classification. Consider what types of oils exist in accordance with it.

  • TA is used for air-cooled brushcutters with an engine displacement of no more than 50 cubic centimeters. It can be used not only for mowers, but also for mopeds, lawn mowers and other types of machinery. For a petrol trimmer, this is the optimal solution.
  • TB is used to refuel a chainsaw, scooter, moped or motorcycle, the engine of which does not exceed 200 cubic centimeters. Can also be used for refueling petrol trimmers.
  • TC is suitable for thinning with gasoline and pouring into a snowmobile, motorcycle and other types of equipment.
  • TD is intended for refueling boats, yachts and gyro scooters.

But in addition to this classification, other letter designations of the FA-FD type are often found. It should be said that the API is an American standard that is used in Europe. But there is a discrepancy between European and American smoke emission regulations. For this reason, additional letter designations should also be taken into account.

  • FA can be used in countries where minimum exhaust gas emissions are required by law. Barely noticeable smoke may be emitted when using oils with such markings.
  • FB. can be used in countries where the restrictions on the emission of smoke and gases are much stricter. In this case, the smoke will practically not be emitted.
  • FC. a transparent smoke appears here, which the human eye cannot notice.
  • FD is a special category of oils for 2-stroke engines, they do not create smoke at all. They have increased chemical properties. Usually this oil is used for mixing with gasoline and subsequent refueling of boats and yachts.

In addition, oils come in two more categories:

  • Selfmix;
  • Premix.

In the first case, this will mean that it is necessary to carry out self-mixing, which does not require shaking, and in the second case, it will be necessary to do it too.

Petrol trimmer oil: types and recommendations for use

  • Appointment
  • Requirements
  • Varieties
  • Selection Tips
  • How to use?

Gasoline trimmers are some of the most popular lawn mowing attachments. They are easy to use, mobile, allow a person to be independent of an outlet and show excellent results where they are used. But for the stable operation of a gasoline trimmer, high-quality consumables are needed. In particular, we are talking about gasoline and oil. It is about the last component that we will talk about in this article.

Appointment

Engine oil is a special blend of solvent and friction-reducing additives. They form a certain viscosity and do not allow the composition to thicken when the temperature is lowered. Usually oils are specially colored in different colors: green, red or blue. This allows them not to be confused.

Please note that they may vary in composition, so petrol trimmer oil will be labeled “for gardening”. In addition, it may still differ in marking: “2T” or “4T”. The first is two-stroke oil, which is poured into the corresponding engine. And the second is intended for pouring into the crankcase.

In addition, you should be aware that under no circumstances should mineral and synthetic oils be mixed due to the fact that they have a different base.

Requirements

A quality oil that can be poured into a gasoline trimmer must meet a number of requirements and standards to ensure reliable operation of the device and its performance. The oil should:

  • provide an increase in wear resistance for various elements (in particular, the gearbox is especially susceptible to this);
  • ensure the formation of smoke and exhaust gases is as low as possible;
  • do not allow premature ignition;
  • mix well with gasoline when exposed to low temperatures;
  • have good viscosity and flow characteristics in various temperature ranges;
  • be as safe as possible in terms of environmental impact.

As mentioned, two-stroke engine oil will differ from four-stroke engine oil. It has higher power, which is why fuel for it is obtained by mixing a certain amount of gasoline and oil. For each brushcutter, the ratio will be different. You can find out its meaning in the instructions for the device. These proportions must be observed with maximum accuracy. When adding additives, take into account the type of motor.

If mineral oils are used, mixing should be somewhere in the ratio of 1: 25, 30 or 35, depending on the type. If we are talking about a synthetic analogue, then the proportion will be 1: 50 or 80. That is, a certain amount of oil dissolves in the volume of gasoline.

How to use?

For the proportions of oil used, see above. We must say right away that you should not deviate from the indicated values ​​and dilute gasoline by eye. At best, you just need to change the oil, and at worst, engine damage cannot be avoided.

It is also important to be able to prepare the mixture correctly. It cannot be poured into the gas tank. It is better to pour the oil into a special container that already contains gasoline. A plastic bottle of mineral water is perfect for this. It is very important that it is clean, which is why beer or milk bottles will not work. And it is better that it be a liter or two-liter, since it will be difficult for many to calculate how much oil to fill in a 1.5-liter or 1.25-liter bottle. You will also need to have a syringe on hand that will function as a dosimeter. It is best to take a regular medical one for 10 or more cubes.

Now we will explain step by step how to make a good gasoline trimmer oil.

  • First, you should find out exactly what type of oil is required for a particular model of the scythe, as well as find out the exact ratio of gasoline and oil to create a mixture.
  • Then you need to fill the container. The container should not be filled with gasoline to the end, because oil must still fit there;
  • Now we draw the required amount of 2-stroke oil into the syringe and pour it into a bottle of gasoline. You can’t do it the other way around, otherwise all the ingredients will need to be replaced, and the mixture will need to be redone.
  • Close the bottle with a lid and stir. It is important not to forget that you need to stir the mixture if there are the words Premix on the bottle of oil. If it says Selfmix, then after mixing the substances, everything is poured into the tank.

Now all that remains is to refuel the petrol trimmer, and you can carry out the necessary work.

Fuel mixture: the proportion of oil and gasoline for the chainsaw

The chainsaw engine is the heart of the tool, so it is very important to use a properly prepared fuel mixture.

The fuel mixture for a chainsaw is prepared from two components. oil and gasoline. Chainsaws are equipped with two-stroke engines, so oil is not added to the lubrication system (like in a four-stroke engine), but directly to gasoline. In this case, it is very important to observe the correct proportions of ingredients, of course, in no case try to work on pure gasoline, because in this way you will very quickly “kill” the chain saw.

If we talk about what kind of gasoline to pour into the chainsaw, then it will be optimal to use fuel with an octane rating of A-95, in this case the savings on fuel can turn out to be deplorable. Often European manufacturers indicate that it is possible to use A-90 or A-92 gasoline, but in post-Soviet countries the quality of gasoline is inferior to that of Europe, so in our realities it is better to use better quality gasoline.

As for the proportion of the petrol-oil mixture itself, everything is simple here: you must follow the instructions for the tool. All manufacturers of chainsaws indicate the required ratio in the instruction manual or in the passport of the tool, in addition, the proportions for refueling the chainsaw may differ depending on the model of the chain saw. As a rule, the proportion of oil and gasoline to a chainsaw of famous manufacturers is a ratio of 1:40 or 1:50, which means 1 part of oil for, for example, 40 parts of gasoline. Now arithmetic 1 liter of gasoline = 1000 ml of gasoline, divide by 40 and we get 25 ml of oil. If you follow the same steps to a ratio of 1:50, you get 20 ml of oil per 1 liter of gasoline. As for budget chainsaws made in China, the situation is slightly different. The ratio of gasoline to chainsaw oil made in China 1:25, that is, divide 1000 ml of gasoline by 25, we get 40 ml of oil. The thing is that in branded chainsaws, a solid assembly and the distance between pistons and cylinders in the engine is much less than that of Chinese chainsaws, therefore, the required amount of oil differs almost twice.

Use a regular medical syringe with sufficient volume to measure the correct amount of oil.

Another subtlety. first fill the dry gasoline can with gasoline and then oil. The procedure, on the contrary, is fraught with a low quality fuel mixture, because the oil is more dense, it will stick to the bottom of the canister. what a good mixing here.

Be sure to prepare the fuel mixture in a canister and pour ready-made special fuel into the gas tank! Never cook or mix directly in the fuel tank of your chainsaw!

If you figured out the question of how to breed gasoline for a chainsaw, then on storage conditions and shelf life of the fuel mixture it is worth saying a few words. It is best and easiest to prepare a petrol-oil mixture for 1 liter of gasoline, it is recommended to do this immediately before working with the tool. Chainsaw fuel tanks have a volume of 0.3 to 1 liter. In the conditions of domestic use, the entire volume of the prepared combustible mixture is rarely used in one session, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special canister for gasoline, in a dry, dark place. It is optimal to count that the shelf life of the finished mixture will be 7-10 days. The fact is that the oil on the market now is not synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats up” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.

At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool will stall (so that the saw has a dry carburetor) and now you can leave it until the next operation.

Unsuitable fuel mixture must be disposed of.

Consequences of violation of the ratio

The service life of the motor scooter depends on how accurately you follow the manufacturer’s recommended oil-gasoline ratio. The fact is that the fuel mixture enters the cylinders in the form of gasoline-oil mist. And the task of the oil composition is to lubricate the moving and rubbing parts and surfaces of various parts in the cylinder. If it suddenly turns out that there is not enough oil, and somewhere it will not be enough at all, the parts that touch dry will begin to damage each other. As a result, scuffs, scratches and chips are formed, which will certainly lead to complete or partial engine failure (for example, it can jam).

In the opposite case, when too much oil enters the engine, it does not have time to completely burn out, settling on the cylinder walls and turning over time into solid particles. coke, slag and the like. As you might guess, this also leads to engine failure. The most important thing is that you must not allow even a single violation of the proportion in the direction of a lack of oil. It is better to pour a little oil 10 times than not to top up just 1 time. It often happens that this time is quite enough to break the engine.

Standard proportions

First of all, it is necessary to take into account the information that the manufacturer recommends, since in the event of a failure of the brushcutter, you can present your claims to him, and not to a third-party source. If there is no instruction in the passport, and even more so if there is no passport, then we recommend that you look for another trimmer model from a more reliable seller.

For all other cases, when you have a petrol cutter model in your hands and there is no way to find out its technical features, there are standard proportions of the most probable components of the fuel mixture for a two-stroke engine. Basically, these units use AI-92 gasoline and a special synthetic oil, which contains a solvent for better mixing with fuel. Such oil evaporates slowly and has the ability to completely burn out in the cylinder, leaving no carbon deposits.

The standard ratio of synthetic oil to gasoline is 1: 50. This means that 5 liters of gasoline requires 100 ml of oil, and in accordance with this oil consumption per 1 liter of gasoline is 20 ml. Knowing the amount of oil required to dilute 1 liter of fuel, you can easily calculate any rates when preparing fuel for the trimmer. When using mineral oils, a ratio of 1: 40 is most often the standard ratio. Therefore, 1 liter of fuel will require 25 ml of such oil, and for a 5-liter canister. 125 ml.

When working with petrol cutters, a person with little experience in operating such equipment will not be difficult to determine and correct the actual amount of oil required for a particular model. You should only pay attention to the exhaust gases (their color, odor toxicity), cycle stability, engine heating and developed power. details about the consequences of incorrect mixing proportions of gasoline and oil can be expected in another section of the article. There are options for brushcutters running on AI-95 gasoline. This should also be considered.

If the manufacturer recommends fuel with such an octane number, then the requirements must be followed so as not to reduce the operating resource of the equipment thereby.

  • How to choose for a petrol cutter?

Gas cutters are a fairly common technique for combating weeds in summer cottages, in household, road and housing and communal services. These devices have two more names. trimmer and brushcutter. These units differ in their engines. The more expensive ones have four-stroke engines, all the others have two-stroke engines. Of course, the latter are the most popular among the population, since they are simpler in design, and lighter in weight, and much cheaper than their four-stroke competitors. However, two-stroke models are inconvenient in that the fuel mixture for them must be prepared by hand, maintaining a strict dosage between gasoline and oil. In four-stroke analogs, the mixing of these components occurs automatically, you only need to fill the gas tank and oil tank with the corresponding substances. Let’s consider the question of the correct filling of the two-stroke brushcutter, since it depends on how effective and long the operation of such a unit will be.

Mixing rules

And now about how to mix the components correctly. However, it would be more logical to start with an analysis of common, but absolutely unacceptable mistakes that many owners of this mowing unit “sin” with. The following actions are considered as mixing errors.

  • Adding oil to the fuel already poured into the brushcutter’s gas tank. In this way, a homogeneous fuel mixture cannot be obtained. Perhaps it will work, if only then shake the trimmer for a long time. But it is unlikely that someone will do this, given the severity of the unit.
  • First pour oil into a mixing container, and then add gasoline to it. Gasoline has a lower density than oil, so if it is poured into oil, it will remain in the upper layer, that is, natural mixing will not occur. Of course, it will be possible to mix later, but much more energy will be required than if it were done the other way around. pour oil into the poured gasoline.
  • Ignoring accurate measuring instruments for taking the required quantities of ingredients used. In other words, diluting the amount of oil or gasoline “by eye” is a bad habit when operating motor vehicles.
  • Take empty drinking water bottles for preparation of the fuel mixture. Such a container is made of too thin polyethylene, which can dissolve with gasoline.

Considering all of the above, we recommend using the following rules when mixing a fuel mixture for two-stroke trimmer engines.

  • Use only clean containers made of metal or special plastic for storage of gasoline, oil, ready-made fuel mixture and its preparation.
  • Use a watering can to pour gasoline into a dilution container to avoid spilling, and to add oil. a measuring container with volume risks or a medical syringe for 5 and 10 ml.
  • First, pour gasoline into the canister for preparing the fuel mixture, and then oil.
  • To dilute the mixture, first pour only half of the planned volume of gasoline into the container.
  • Next, add to the gasoline the entire amount of oil required to prepare the mixture.
  • Mix the contents of the dilution container thoroughly. It is best to stir by making circular movements with a tightly closed container. You should not stir the fuel inside the canister with any foreign object, since it is not known what material this object is made of, what reaction it can enter into with the ingredients of the mixture, how clean it is.
  • Add the rest of the gasoline to the mixed mixture and mix thoroughly again.
  • You can fill the fuel tank with the prepared mixture.

It must be borne in mind that the ready-made fuel mixture should not be stored for more than 14 days, as it loses its properties, stratifies and evaporates, which leads to changes in proportions, and therefore a deterioration in trimmer performance.

How to choose for a petrol cutter?

For two-stroke engines, brushcutters use AI-92 or AI-95 gasoline. Most often. the first of the named. There is always information about this in the technical data sheet of the product. If, for some reason, it is not known exactly on what gasoline the trimmer should work, you can pick it up by testing both brands of gasoline in action. Global changes in the engine will not happen from this, and it is quite possible to determine what kind of gasoline this or that model of the unit “likes” more, according to some factors. This will be shown by the developed power, and throttle response, and engine heating, as well as its stable operation at all speeds.

But it is much more difficult to determine the proportions of oil to a certain volume of gasoline. In this case, you need to know at least something about the manufacturer of the equipment. And already according to the standard proportions for this manufacturer, select the proportion for a specific model, taking into account the type of oil.

You can start selection even by country of origin.

For example, for Chinese low-power trimmers, two ratios are mainly used. 1: 25 or 1: 32. The first is for mineral oils, and the second is for synthetic oils. We have already talked about the choice of standard proportions for petrol cutters of European and American manufacturers in connection with the type of oil. According to the class of oils for household trimmers, it is necessary to use TB oil according to the API classification. For more powerful. vehicle class.
