How much oil is needed per trimmer per liter

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 equipment and with an air type of cooling, 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 gardening 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.

Lawn mower manufacturers often produce the right oil, so you can make your choice easier if you choose the right brand fluid.

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 mower components, 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 lawn 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.

much, needed, trimmer, liter

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.

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 damage the device, 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, such as using a special lawn mower lubricant and diluting it in a separate container. It is also recommended to use special canisters designed for storing gasoline.

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

A trimmer, or lawn mower, 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.

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 the 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. At the same time, it is recommended to choose only a high-quality product of the corresponding brand.

Oil selection and fuel mixture for lawn mowers

So, have you finally become the owner of a petrol lawn mower 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. lawn mower 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-cooled 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 feature is the color, which can be green, red or blue. Of course, this does not mean that some lubricant is better, but some 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, lawn mowers, 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 lawn mowers, 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 lawn mowers: 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 the 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 lawn mowers?

Everything is quite simple, subject to 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 your lawn mower, you need to familiarize yourself with the performance 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 the correct proportion of lawn mower oil, 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 enough 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 have 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 lawn mowers prepared 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:

secrets of 2 stroke engines oil x gas mixture

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 evenly inside the engine. Then, return the candle to its original state. Store equipment in a cool dry place.

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. At the same time, 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 chainsaw.

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 operating 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 1:50 ratio, 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.

In order to measure the correct amount of oil, use a conventional medical syringe of sufficient volume.

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 session.

Unsuitable fuel mixture must be disposed of.

Helpful advice

Plastic cans for gasoline are always marked with the flame sign. It is very convenient to use a canister equipped with a spill-free refueling system (see Figure 3). The spill-free system has a valve that prevents fuel from spilling when the tank is full.

Figure 3- Spill-free filling system

Helpful advice

It is not recommended to use a fuel mixture if more than two months have passed since preparation.

    Let’s summarize the above. Use oil for your branded appliances that has been developed or recommended by the manufacturer of that technique. For example, for Stihl FS 55 lawn mowers Stihl HP oil (see Figure 1a) or Stihl HP SUPER oil, for Husqvarna 128R lawn mowers use Husqvarna HP oil (Figure 1b) or Husqvarna LS oil. For 2-stroke engines, do not use 4-stroke engine oils. e.g. 10W30, SAE 30, etc.

    Figure 1 a-Husqvarna oil (Left), b-Stihl oil (right)

    Toys.Children’s chainsaws

    Helpful advice

    It is necessary to observe the proportions of oil and gasoline for the fuel mixture specified by the manufacturers in the operating instructions. Chinese manufacturers most often indicate the proportion. 1 part oil to 25 parts gasoline, for Stihl and Husqvarna this proportion will be 1/50. When preparing a small volume of a mixture (up to 1 liter), it is very important to carefully measure the amount of oil included in the mixture. Even small miscalculations in the amount of oil can lead to serious inconsistencies in the mixture. In these cases, a medical syringe can be used for accurate dosing.
    The preparation of the fuel mixture must be carried out in a clean container specially designed for this. (see figure 2)

    Mixing ratio

    Often the standard mixing ratios are indicated on the oil container. And basically a ratio of 1 to 50 is used. This is how much oil should be added, we will consider below. Slight deviation from the ratio shown is possible. But it’s better to stick to exact dosages.

    So, manufacturers recommend a 1 to 50 ratio. How much oil should you dilute with gasoline? The ratio of the presented proportion is quite simple:

    • 1 liter of gasoline and 20 ml of oil;
    • 1.5 liters of fuel and 30 ml of oil;
    • 2 liters of fuel and 40 ml of oil.

    For the calculation, the formula is applied: 1 l / 50 1000 = 20 ml.

    Therefore, 20 ml of oil is needed per liter of gasoline.

    For convenience, you can use a medical syringe to accurately measure the volume of the lubricant composition or take another measuring container with graduations in milliliters.

    Owners of scooters and motorcycles, as well as owners of gasoline-powered tools with a two-stroke engine, are faced with the need to fill the fuel tank with a pre-prepared mixture of gasoline and oil, maintaining the required proportions. Motorists know that they cannot refuel equipment with a two-stroke power unit with pure gasoline. This will adversely affect the operation of the motor, its resource and lead to inevitable breakdowns. The oil-gasoline table will help determine the correct ratio of the amount of fuel and lubricant.

    Let’s take a closer look at the principle of two-stroke operation, understand the mixing proportions, as well as the rules for preparing the fuel mixture.

    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 mowers’ 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 it will take much more energy 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 fill 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. Do 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 of the lawn mowers 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.

    Cooking recommendations

    Most drivers know that a two-stroke engine runs on petrol-oil fuel. Therefore, it is recommended to observe the proportions indicated in the product data sheet.

    Of course, some experienced vehicle owners create proportions by eye. However, each time such a mass will have a different ratio. This will adversely affect the performance of the motor. Therefore, you need to read the instructions on the packaging.

    Recommended requirements for the operation of the mixture:

    • Do not reduce the amount of oil component when mixed with fuel. You need to adhere to a ratio of 1 to 50. How much oil is this? You need to know the exact amount before pouring the mixture into the crankcase. Oil is not a cheap component, so they often try to save money on it. But this can contribute to strong heating of the system. Therefore, the proportions of the oil must be observed. Also, due to the insufficient amount of this component, scuffs may appear, which significantly reduces the duration of the motor’s operation.
    • Also, do not use copious amounts of oil. Exceeding its volume is a negative factor for engine operation. This leads to rapid wear of the motor, to an increase in carbon deposits.
    • It is not recommended to store the prepared fuel mixture for more than 30 days. Otherwise, it loses the desired properties, and its use will significantly reduce the service life of the engine.
    • It is required to ensure that there is no dust, dirt in the composition, as this will also negatively affect the operation of the motor.

    How to determine if the mixing ratio is out of order

    There are a number of indirect signs by which it is possible to determine the discrepancy between the amount of gasoline and oil when preparing the mixture:

    • the formation of contaminants in the float chamber and carburetor channels;
    • significant resinous deposits on the elements of the fuel system;
    • oxidation of carburetor walls and reduced elasticity of rubber parts.

    Any of these signs indicates the need to adjust the mixing process. Observing the proportions recommended by the manufacturer, it is possible to ensure a long service life of a two-stroke engine, as well as to avoid unforeseen and, at times, expensive repairs.

    lawn mowers 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 lawn mower. 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 issue of the correct refueling of two-stroke lawn mowers, since it depends on how effective and long the operation of such a unit will be.

    Consequences of violation of the ratio

    The service life of the motor scooter depends on how accurately you follow the manufacturer’s recommended proportions of the oil-gasoline mixture. 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 towards the 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.

    What oil to dilute gasoline for a motorcycle

    In two-stroke engines, there is no separate filling of lubricant into the crankcase.

    Strict requirements are imposed on oil that burns together with fuel:

    • the lubricating fluid must provide effective lubrication of all parts;
    • the oil should burn easily and should not form carbon deposits after burning.

    The use of low-quality oil for two-stroke engines is the reason for the formation of carbon deposits in the working chamber and a decrease in power.

    When deciding on the type of oil, one should be guided by the recommendations of the manufacturer of the equipment specified in the operating manual. Preference should be given to branded oils from renowned manufacturers. The preferred oil grade is API-TB. It is also possible to use oils with the API-TC mark.

    The choice of the type of lubricant is carried out depending on the climatic conditions:

    • in the warm season, gasoline can be diluted with mineral oil;
    • in the winter months, it is worth giving preference to synthetic oils;
    • branded semi-synthetics are suitable for all-season use.

    The recommendations of the manufacturer of the equipment should be guided by determining the type of oil

    For detailed information on the temperature threshold of use, read the information on the packaging of the oil. Knowing the ratio of fuel to oil required for stable engine operation, as well as the volume of the gas tank, you can easily calculate how much oil is required for a certain period, taking into account the frequency of trips or the use of gas powered tools.

    When buying oil for preparing the fuel mixture, you should pay attention to its purpose. This information is indicated on the packaging. It is not permissible to use tractor oil or boat lubricant for mixing with gasoline to refuel a scooter or motorcycle. Please note that on the brand label of oil for two-stroke engines it must be marked 2T.

    How much oil to pour into gasoline. mixing rules

    Having figured out how much oil to pour into gasoline, you can start preparing the fuel mixture. This will require a clean metal or plastic canister. First, the required amount of gasoline is poured, and then lubricating fluid is added in the required volume. After completing the dilution, tilt the canister a couple of times.

    As a result of repeated shaking, the liquids are mixed, and the prepared fuel acquires a uniform color. Depending on the color of the added oil, the finished liquid can be greenish, bluish or reddish.

    When performing work, safety precautions and fire regulations should be observed. Mixing work must be carried out in a ventilated area, and even better outdoors. Do not smoke when working with flammable liquids. Mixing must be done with gloves to protect the skin from aggressive liquids.

    The prepared mixture fills the fuel tank and the gas tank cap is tightly closed. Gasoline mixed with oil can be stored in tightly closed containers. Gasoline mixed with oil retains its properties for a month.

    That is why mixing should be done immediately before pouring, taking into account the frequency of use of a scooter or motorcycle.

    • You can fill the fuel tank of the lawn mowers 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.

    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 lawn mowers, 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 lawn mower model in your hands and there is no way to find out its technical features, there are standard proportions of the most likely fuel mixture components 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 lawn mowers are working, 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 lawn mowers 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.

    • How to choose for lawn mowers?

    lawn mowers 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 lawn mower. 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 issue of the correct refueling of two-stroke lawn mowers, since it depends on how effective and long the operation of such a unit will be.

    Consequences of violation of the ratio

    The service life of the motor scooter depends on how accurately you follow the manufacturer’s recommended proportions of the oil-gasoline mixture. 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 towards the 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.

    How to choose for lawn mowers?

    For two-stroke engines, lawn mowers 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 lawn mowers 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.
