The ratio of gasoline and oil for a trimmer for Huter grass
Units are deprived of a separate oil distribution system. It is implemented by making a fuel-lubricant mixture from gasoline and grade 2t oil. It is kneaded in certain proportions. They can be indicated in the instructions for the lawn mower, or the trimmer, as well as the lubricant manufacturer himself.
The resulting mixture, upon admission to orally, lubricates moving parts and gradually completely burns out. Spent gases and combustion products are displayed into the atmosphere. Then the cylinder is blowing.
The correctly prepared mixture completely burns in the cylinder. Violation of proportions leads to the formation of soil and an increased exhaust. The composition with low m combiing materials is not able to sufficiently lubricate and protect important nodes and elements. This will lead to an ambulance.
Storage is allowed, and preparation in a metal container, glass and special containers. It is strictly forbidden to use plastic dishes and polyethylene for this. Materials under the influence of fuel decompose and reduce the quality of the finished product.
To increase efficiency, experts recommend only a freshly prepared substance.

On the market there is a garden technique with a two.stroke engine, which has 2 fundamentally different methods of mixing oil with gasoline:
- A separate tank is installed for each liquid. The mixture is formed in the intake pipe installed between the cylinder and the carburetor. Such devices are more massive and heavy, since they are equipped with additional containers that serve as highways and a plunger pump. The design helps to achieve an accurate dosage. A balanced product helps to reduce consumption, reduce the amount of exhaust gases secreted and slows down cooking.
- Liquids enter one tank. Mixed with proportions indicated by manufacturers of equipment and oils. Violation leads to negative consequences.
The consequences of refueling with a mixture with incorrect proportions
When diluting, combustible materials are very important to observe the ratio recommended by the manufacturer Motokos. If the oils are not enough, then bulletin forms on the piston and cylinder, which sooner or later is led to breakdown of the piston ring
Important! In addition, as a result of friction, the metal from the piston settles on the walls of the cylinder, and the engine can simply jam. This will require repair or replacement of the motor
And with an excessive amount of oil, the piston ring is shielding, as well as the formation of soot on the piston, on the spark plug, etc.D. All this leads to strong wear of equipment and the need for constant cleaning.
Differences in gasoline engines
Gasoline engines are two.stroke and four.stroke. To understand the difference, you need to know the two nuances: firstly, that during the engine operation a number of transition processes occur, and secondly, that the tact means the movement of the piston from one extreme position to another, while the direction of movement does not have a value. The essence of the classification of engines is that the entire cycle of transition processes in one case is repeated in two tacts, in the other. over four.
The differences between 2t and 4t, which relate directly to the process of refueling, can be understood without even going into the subtleties of the main nodes. In a two.stroke engine, the supply of the fuel mixture to the cylinder, and the release of the exhaust gases occurs almost simultaneously. In this case, the fuel fog initially enters the crankcase, where the crankshaft is located. When moving down, the piston squeezes part of the mixture from this chamber to the working area through the window in the cylinder wall.
In a four.stroke engine, the combustion chamber is separated from the crankcase. The supply of fuel.air mixture occurs through the inlet valve, the release of the exhaust gases. through the graduation. Dutch control is carried out by a separate node driven by a crankshaft, while the procedure for their opening and closing is synchronized with the piston strokes. Due to the separation of the working area from the crankcase and the four.stroke order of operation, the complete combustion of the fuel and the almost complete removal of the exhaust gases from the working area before injection of the next portion of the mixture are ensured.
How lubrication systems work
Both types of engines contain a fair amount of moving elements. To increase the resource of their work, the presence of lubrication is required. Its feed on two-stroke and four-stroke engines is carried out differently and this kind of nuances are directly related to the procedure for refueling and maintenance.
The supply of lubrication in a two.stroke engine is performed along with the fuel mixture. The oil dissolved in fuel is sprayed along with gasoline in the carburetor, the formed fog enters the chamber. The configuration of the channels is organized in such a way that the route of sprayed lubrication is as long as possible and passes through the main moving nodes. At the same time, due to the special properties of the oil, most of it settles on the metal parts, and the purified fuel is transmitted to the working area of the cylinder. It is thanks to these properties that oil for two.stroke engines is radically different from other types.
In a four.stroke engine, the oil in an isolated crankcase is constantly. Its level is controlled in such a way that the crankshaft neck periodically plunge into the oil bath. At the same time, a balanced ledge when rotating due to centrifugal force sprinkles oil through the internal volume, so the lubricant enters the piston cavity and onto the tarnished finger, as well as on the walls, due to which it is effectively cooled. So that the oil does not fall into the combustion chamber, an additional corrugated ring is installed on the piston, which relieves oil residues from the cylinder walls when the connecting rod moves down.
How to refuel a trimmer for grass
The finished mixture of gasoline with butter can be stored for no more than 3 months (clean gasoline is stored less). Dilute the fuel in the quantity that is enough for several applications of the trimmer for the grass. In general, prepare:
- gasoline and oil, which is suitable for two.stroke engines with an air cooling system;
- metal canister and a mixture container;
- Pour 1 l of gasoline into a suitable volume of 1 l of gasoline and add 1/2 of the desired amount of oil.
- Mix carefully, being at a decent distance from the sources of open fire.
- Add the rest of the oil to combustible and mix everything again.
General recommendations for refueling a trimmer for grass with a two-or four-stroke engine:
- Place the fuel tank so that the lid is located on top, and then pour the required amount of fuel.
- Do not overfill the fuel tank. This will lead to one of the problems: transferring into the intake pipe and fuel filter, flammable ignition or breakdown of the motor.
- Try to fill the mixture so that it does not spill. To do this, you can use the watering can.
- If you still poured fuel, then immediately wipe it. Put the wiping material, do not accumulate indoors. this is fire hazardous.
- The launch of the device should begin after the canister with fuel is removed at a distance of more than 10 m.
- If there was a long break between the operations of the mowing, then the remaining old fuel be sure to drain.
We proceed to running the lawn mower
After starting, do not rush to immediately run the trimmer for the grass. Let the engine idle for 5 minutes. While heating is going on, adjust the air supply to the air damper with a lever so that the rogue with a fishing line or with a knife does not rotate. As soon as the tool warmed up, we completely open the air supply to the corresponding lever to the “ON” position and squeeze the gas trigger for 1/2 and hold the seconds of seconds 30. Then we drop the gas, let the trimmer work on xx 30.40 seconds. In this mode we continue 10 minutes 15. Then we mock and let it rest for 15 20 minutes.
Having cooled the lawn mower, we continue to run the engine according to the previous scheme. Start a hot, a trimmer for grass should already be with an open air damper. Try not to hold the gas for a long time, since the movable details of the tool only rubbing each other. And do not let the engine work at idle for a long time as it can overheat.
The next stage is the run.in a gas reducer gearbox for grass. To do this, select a plot with soft young grass. Kosim 5 10 minutes with 1/2 2/3 from full gas. After we take a break for 20 25 minutes. Repeat the cycle 3 4 times.
In general, therapist for the lawn mowing according to the described algorithm is carried out until the fuel mixture in the tank is fully generated. After which the tool is ready for long.term work. In the process, follow the temperature regime of the gearbox and the motor. They should not overheat.
Requirements for clockwork
A mixture of gasoline and oil selected for motorcycles must comply with the necessary requirements specified in the instructions. It is important to note that domestic manufacturers often mark their products a little differently, not as it is customary according to the American or Japanese classification. Manufacturers of lubricants, as a rule, put 2t marking in all oils intended for two.stroke engines. Often on store shelves you can find canists with butter, on which there are marks “Self Mix” or “Pre Mix”. In the first case, this means that the oil does not require any additional manipulations, it is enough to simply pour gasoline with butter into one container, and mixing will occur without human participation. In the second case, accordingly, you will have to shake or shake the mixture to bring it to the desired consistency.
As you can see, the existence of various classifications of lubricants suggests that the use of oils in two.stroke engines is necessary. This is due to the fact that the fuel mixture without a lubricant will quickly disable the internal combustion engine, which will not be lubricated properly. Gasoline with butter forms the necessary environment, which reduces detonation, removes excess garbage (working out from the combustion of gasoline products) and protects the inner surface of the engine from wear.
It is important to remember that when using the oil of the wrong classification, a breakdown or clogging of the motor may occur. Of course, it can be repaired, but in order to prevent possible breakdowns, and minimize their probability, it will be better to study the operating instructions, find out the volume of a two.stroke engine installed on a motorcycle, and use only gasoline with oil that will fit this parameters. Models.
Quite often in the recommendation section (and sometimes on the label), the manufacturer indicates partner companies, whose gasoline with butter recommends pouring into his models. Most often, fuel and lubricant recommended by the manufacturer are suitable for a trimmer for grass best.
First of all, all the oils of unknown (garage, basement) of origin should be immediately excluded from the list of actively operated lubricants. Usually diluting such oils is not easy due to an unclear base, composition. As a rule, the labels of irregular manufacturers do not abound information, illuminating only general information, without clarification. It is extremely recommended to dilute and dilute oils such as AS-10 and ASZP-10. The origin of these lubricants is usually very vague, it is better to give preference to proven brands that thousands of people throughout the country use every day.
A distinctive feature of all oils for two.stroke engines is the fact that manufacturers stain them in a color contrasting with gasoline. The liquid is translucent, viscous in consistency, slightly yellowish, but not thick. Usually, we are talking about three colors. red, green and blue.
Do not forget that the color scheme does not affect the classification in any way (as is often done in the case of antifreeze).
In no case should you use oils from a ruler not designed for a trimmer for grass. This can extremely negatively affect the work of the power unit, lead to increased fuel consumption, soot on candles and a number of other problems that will have to be identified and eliminated. It should be noted that if the fact of using oil that is not included in the tolerances will be installed, the seller has every right to remove the device from a guarantee. This means that the replacement of failed parts will have to be at their own expense, and no exceptions will help here.
If the acquired liquid does not have the declared qualities (for example, too liquid), in no case should it mix it with gasoline. It will be best to return such oil back to the store, explaining to the seller the reason for the return.
Fuel mixture for two.stroke engines
Trammers for grass that are equipped with a two.stroke engine do not have a separate system designed to supply oil in order to lubricate the rubbing parts. For this reason, such devices should not be refueled with clean gasoline, but a mixture of fuel with engine oil. The latter should be specially designed for two.stroke engines. The use of automotive motor fluid will lead to the premature failure of the engine.
Preparation of fuel mixture for two.roll engines
Refueling the lawn mower with a two-stroke engine needs gasoline AI-92 brand. When using AI-95, engine overheating and uneven operation of the unit may be observed. Mix gasoline with butter in a ratio of 50: 1, where 50 is fuel, and 1 is oil. It turns out that 20 ml of oil will need 1 liter of fuel.
If the motor is worn or the tool works with a high load, then the proportion is 25: 1. If there is little lubrication, then on the walls of the cylinder and the surface of the piston will appear. Then the piston ring will be destroyed, as a result of which the engine will jam. An excess is not so critical, but it can lead to the formation of a carbon. The piston ring is overwhelmed, which will reduce the power of the device.
Oil and gasoline proportions for the fuel mixture
How to mix oil with gasoline for a two.stroke engine
The peculiarity of the operation of two.stroke engines is that the fuel is refueling into the tank along with the oil. Each refueling before the operation of equipment requires the preparation of the fuel mixture in compliance with the proportions. How to do everything right? From our article you will learn how to dilute gasoline for a chainsaw, a trimmer for grass and other garden tools.
Fuel mixture preparation instructions
For the operation of garden equipment, it is recommended to buy unhealthy gasoline. Otherwise there is a risk of engine system. Manufacturers advise fuel with an octane number not lower than the AI-90, better AI-92 or AI-95. Individual recommendations for your tools see in the instructions. At the gas station, pour the required amount of fuel into the canister. It is advisable to take a metal one: static electricity from friction does not occur in such a container, which increases the safety of use.
Buy branded oils for two-stroke engines, preferably API-TB or API-TC class. Recommended brands manufacturer should indicate in the instructions for the tool. Also consider their composition. Mineral oils are suitable for use in warm weather. Synthetic, they are less viscous and can be used even in the frost. Semi.synthetic. these are minerals with improved qualities that are universal for any season. See the temperature limit of operation on the packaging
Pay attention to the volume. It is not the proportion of gasoline and oil for a chainsaw is important, but how many fuel mixture you will need for one refueling and how often you will work as a tool
If in your arsenal, in addition to the saw, there is still a trimmer for grass or gasoline and you use this or that tool several times a week, it makes sense to buy a large canister of oil with a volume of 3 to 5 liters. For several mowing for the summer season, it is enough to take a bottle for 1 liter.
At the beginning of work with the tool, the question always arises how much oil to add to gasoline for a chainsaw or a trimmer for grass
It is important to remember that for two.stroke engines the ratio is 1:50, t.e. per 5 liter of fuel accounts for 100 ml of oil
Why is it important to observe the proportions? Excess oil contribute to the appearance of soot on pistons and candles, and its deficiency worsens the lubricating properties of the fuel mixture, which leads to the formation of bully on the piston group and increases the risk of engine breakdown.
The easiest way to follow the proportions of gasoline and oil for the chainsaw, using measuring containers. They have a scale with marks on which it is easy to navigate. Before filling gasoline and oil, make sure that the capacity is clean. Avoid getting into water and dirt. this may affect the quality of the fuel mixture. Pour the gasoline first to the required mark, then share the oil. also to the desired mark. To mix them, tilt the container several times. The liquids are quickly mixed, and the composition will acquire a uniform color, for example, green or red (depending on the composition of the oil).
It’s important to know! In no case do not use plastic bottles of drinks for storage and mixing fuel mixture. Gasoline corrodes plastic
And even if the walls of the bottle are intact, harmful components will fall into the fuel mixture, and with it to the engine. It is very harmful to the carburetor.
cooking with Gasoline (Petrol) cuts rising cost in LPG COOKING GAS
It is recommended to work in gloves to protect your hands from gasoline and oil. Also do not forget about the elementary fire safety rules. Mix the liquids on the street so that the vapors of gasoline do not accumulate indoors. Do not smoke during work and exclude other factors that can cause ignition of combustible materials.
Pour the prepared fuel mixture into the fuel tank and close the lid tightly. If you have made more mixtures than you can use it at a time, squeeze it into a separate canister for storage or leave it in a mixture container. The main thing is to close the lid tightly. The finished mixture can be stored for two weeks and used for refueling without risk for the engine. The only condition. do not leave it in the fuel tank. If the tool will not be used for a long time. spent the rest completely or drain.
First of all, it is necessary to take into account the information that the manufacturer recommends, since in the case of failure of the motorcycles, you can make your claims to him, and not a third.party source. If there is no instructions in the passport, and even more so if the passport is missing, then we recommend looking for another trimmer model for grass at 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 components of the fuel mixture for a two.stroke engine. Basically, these units use AI-92 gasoline and special synthetic oil, which contains a solvent for better mixing with fuel. Such oil evaporates slowly and has the ability to completely burn in the cylinder, without leaving a car.
The standard attitude of synthetic oil to gasoline is 1: 50. This means that 100 ml of oil needs 5 liters of gasoline, 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 norms when preparing fuel for a trimmer for grass. When using mineral oils, the ratio of 1: 40 is most often standard. Therefore, 1 liter of fuel will require 25 ml of such oil, and 125 ml per 5-liter canister.
When the lawn mower is working, it will not be difficult to determine and adjust the actual amount of oil, the right of a particular model, who has a little experience in the operation of such a technique
You should only pay attention to exhaust gases (their color, toxicity of the smell), stability of the cycles, engine heating and developed power. about what consequences from the incorrect proportions of mixing gasoline and oil can be expected is lit in another section of the article
There are motorcycles operating on gasoline AI-95 brand gasoline. It should also be taken into account.
If the manufacturer recommends fuel with such an octane number, then you need to follow the requirements so as not to reduce the working resource of technology.
What gasoline to fill in a trimmer for grass. What gasoline can be poured into a trimmer for grass?
Before finding what gasoline can be poured into a trimmer for grass, you need to determine some concepts used.
- Trammers for grass can be with four.stroke or two.stroke engines. Four.stroke trimmers for grass are more massive and complex in design, lubrication of the details of its motor is carried out due to the oil pump. The engine works on clean gasoline. For two.stroke units. more ordinary. it is required to make a fuel consistency consisting of gasoline and oil. Here is due to the amount of oil that is in combustible, and the rubbing parts in the cylinder of this motor are lubricated.
- For the manufacture of consistency, gasoline of a certain AI-95 or AI-92 brand is needed. The brand of gasoline is located depending on its ignition rate. the octane number. The lower this indicator, the more freaks burning gasoline and its larger consumption.
Many models of benzos have two-stroke engines that work to a greater extent on AI-92 gasoline. Fuel for them must be connected without the help of others. It is better to pour gasoline of the brand that is determined for it by the manufacturer, another trimmer for the grass will be out of order. For example, with gasoline of the AI-95 brand, the engine will rapidly overshadowed, and when choosing AI-80, the fuel mixture comes out completely low, because the work of the motor will be unstable and with low power.
In addition to choosing a brand of gasoline, in the manufacture of fuel shift for motorcycles, it is necessary to use a special oil designed specifically for two.stroke engines. Semi.synthetic and synthetic oils are perfect for benzos. Semi.synthetic oils are in the average price spectrum, suitable for such technology from at least some manufacturer, lubricate the necessary elements of the motor well. Synthetic oils are more expensive, but when using them, the engine will work longer. In any case, when buying equipment, you should closely familiarize yourself with the annotation, because from time to time the manufacturer gives advice on the use of certain brands of oil.
Learning to dilute gasoline with oil for a trimmer for grass if you do not have or pour oil
If you bought a trimmer for grass, a lawn mower, a motorcycle, a chainsaw and other types of equipment, then you probably know that two.stroke engines are used as power units on them. These motors do not work on pure gasoline, like four.stroke, but on a mixture of gasoline with butter. In what proportion should be diluted gasoline with oil for a trimmer for grass. this question asks for himself every summer resident before preparing the tool for work. We will figure out in detail in this matter, since the dilution of gasoline with oil for a trimmer for grass affects the life of the tool, and improper preparation of the mixture will lead to rapid engine wear. What is the dangerous or insufficient amount of oil in gasoline for a trimmer for grass:
- If gasoline is diluted with a large amount of oil (above the norm), this will lead not only to a large amount of smoke, but also to the formation of a carbon on the walls of the cylinder and a drop in power. This incapacitance will cause wear of the piston, which will be diagnosed to reduce its performance
- If gasoline contains an insufficient amount of oil poured into a trimmer for grass, then this is even more dangerous. After all, the working mechanisms of the engine will not be lubricated in sufficient quantities, which will ultimately lead to their rapid wear (rapid destruction of the piston rings and jamming of the motor occurs). With an insufficient amount of oil in gasoline, poured into a trimmer for grass, the wear of the motor will occur ten times faster
So that you do not have to pay for errors at the cost of overhaul of the engine or buying a new tool, it is necessary to fill the fuel of the correct consistency into the tank from the first day. You can find out the ratio in the instructions for the tool, since models of different manufacturers can give different recommendations. Usually this ratio is the following norms:
- 1 to 25 or 1 liter of gasoline 40 grams of two.stroke oil
- 1 to 40 or 1 liter of gasoline 25-30 grams of grease
- 1 to 50. this is added to a liter of gasoline 20 grams of oil
The value of 1 to 50 is considered standard (indicated on canister with butter for two.stroke engines), but it is necessary to rely on it in the most extreme case, since the manufacturers indicate the recommended value of the proportion, and if it is not observed, the operational resource of a two.stroke motor decreases.
In addition to observing the proportion, you must also learn to prepare the mixture. After all, the option of adding oil to the gas tank is categorically contraindicated, although some do so. If you bought a trimmer for grass or a lawn mower, you will need the consumables that you will use to prepare the mixture. Instructions for the preparation of the fuel mixture in a trimmer for grass have the following view:
Prepare gasoline and two.stroke oil, based on the above recommendations for the choice of a lubricant and fuel in addition, for the preparation of the mixture, you need to take a container or container. Typically, a plastic bottle is used for this, the choice of which needs an appropriate approach. It should be clean inside. Using a milk container and other drinks is not recommended
The best option is a container from mineral water it is very important that the capacity has a whole value of volume, that is, 1 or 2 liters, so that you do not have to calculate how much oil is poured into a bottle per 1.5 liters, 1.3 or 1.25 After all, you can easily be mistaken, you can also need a syringe that is used as a measured device for dosing. For such purposes, a regular medical syringe for 10 cubes is suitable
It is desirable that the syringe has an exact measuring scale after preparing the necessary materials, you can proceed to cook
Instructions for the preparation of the fuel mixture in the lawn mower:
- First you should fill a plastic container. The container is filled with 2 fingers not supplemented to fit the oil
- The required amount of two.stroke oil is typed in a syringe, and poured into a bottle with gasoline. You need to do just that, and not vice versa
- After adding a lubricant to the bottle, it requires to close it tightly with a lid and stir. However, take into account that the streaming needs oil with the designation “Pre mix”. If the container “Self mix” is on the container with oil, then you do not need to shake the container, and after connecting the substances, you can pour them into the tool tank
After preparing a fuel mixture for a trimmer for grass, it remains to season the tool, and start work. How to correctly refuel trimmers for grass, lawn mowers, chainsaws and other types of motorcycles, consider in detail.
DLE Dilutions and use in the trimmer only fresh gasoline is used.
What to look for when choosing oil?
When choosing oil for your lawn mower, you need to pay attention to the manufacturer of products. Preference should be given to the brand that is indicated in the instructions for the technique. A large number of manufacturers of this technique are engaged in the production of their own oils. They should use them. They positively affect the performance and life of the equipment. When choosing, you need to focus on the overall characteristics of the lubrication, which are given in the instructions. It is forbidden to use the first one that falls, no matter which lawmaker is: self.propelled or gasoline. Do not buy the most expensive lubricant, it may not approach a specific model. There is no universal option.
The oil is recommended to change every 50-60 hours of operation of the lawn mower
What oil can not be filled?
It is forbidden to pour a lubricant on the 4-stroke gas mowing engine, on the label of which there is 2T labeling-it is designed for two-stroke. After purchase, fuel is stored no more than 2 months. It is forbidden to use polyethylene canists for storage. As a result of the contact of fuel with the internal walls, static electricity may occur. If a spark is accidentally appearing, an explosion may occur. Today, special canists made of plastic appeared on sale, on which the marking “Flame” is worth.
The operation of the lawn mower depends on flooded gasoline and oil. No need to save on them, otherwise the technique will quickly stop performing its functions, you will have to repair it.
How to mix
If you do not have a special measuring canister with divisions that are included in the set of the Trammer deserving attention for the grass, or such a container has been lost, then use any suitable container. Better glass or metal. Plastic can also be used, but you need to choose a bottle with hard walls.
The capacity of the vessel should be a multiple of 1 liter. You can take a bottle and 1.5 liters, but practice shows that it is not very convenient. You also need a medical syringe, preferably 20. 50 milliliters. First, gasoline is poured into the container, then an accurate amount of oil is added (by volume). The procedure cannot be changed.
If you have Pre Mix oil, then you need to close the bottle or canister and turn it upside down several times and shake it hard. If Self Mix oil, then it will dissolve on its own. The prepared mixture must be used throughout the day. If you know how much fuel is the trimmer for grass for a certain amount of work (or time), then calculating the amount of the mixture is not difficult. Otherwise, before each refueling, dilute the new fuel so that the minimum amount remains until the end of the work.
Classification of lubricants
The main difference between the principles of the work of a two- and four-stroke internal combustion engine (ICE) is that in the case of a 4-stroke unit, lubrication of the rubbing parts occurs using a crankcase and an oil pump. The capacities of the four.stroke engine allow us to ensure the operation of this unit. And in a trimmer for grass with a two.stroke engine, a mixture of gasoline and oil for lubricating the entire system (cylinder and pistons, crankshaft, bearings support) is required. To correctly dilute and prepare such a mixture for a trimmer for grass, there is a special classification, more often presented as a table.
The oil in the trimmer is no different from the lubricants intended for another summer cottage technique equipped with a two-stroke ICE. It has the same composition, a package of additives and detergents. Let us consider in more detail the American classification of oils, or, as it is commonly called, API.
- The TA group is designed for use in trimmers and mopes with air cooling of a two.stroke engine. The declared volume of devices from 50 cubic meters.cm up to 200 cubic meters.cm.
- The TV group is also used in trimmers and other garden equipment, only with an already increased engine volume.
It must be remembered that the groups and TV are not interchangeable, the ratio of gasoline and oil may differ in them.
Its own classification of oils exists in the same way in the Japanese. Unlike the generally accepted American classification all over the world, Japanese is designed mainly for environmental norms.
- The FA group is designed for use in trimmers and other devices for countries where the norms for exhaust are rather low.
- The FB group is intended for trimmers with a two.stroke engine, where the legislative requirements for the exhaust are significantly increased.
- The FC group for trimmers, where the requirements for the development of gasoline and oil are minimal. zero exhaust.
The remaining classifications are not intended for trimmers.
The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92. For the preparation of fuel, consumables with overdue storage, made on the basis of gas condensate, having water and mechanical impurities in its volume.
- The opinions of experts on the use of gasolines of different brands are ambiguous. On the one hand, incomplete compliance with domestic gasoline A-92 European standards is recognized.
- On the other hand, the quality of gasoline A-95 is questioned due to the high content of anti-depth additives. You can use this fuel for the preparation of fuel for a chainsaw only with complete confidence in its quality.
- The difficulty lies in the presence of various improvement additives, with which unscrupulous manufacturers and sales increase the operational properties of automobile gasoline with a lower octane indicator.
There are also irreversible changes in the working properties of fuel with a sufficiently long storage in plastic containers, regardless of its level of gas resistance.
STIHL for a two.stroke HP engine, 1 liter
Mineral motor oil, designed for the requirements of gasoline instruments of domestic and imported production, is characterized by good lubricating properties and the optimal ratio of additives. Consumers praised the wide possibilities of this lubricant. It can be poured into trimmers for grass, lawn mowers, chainsaws with two.stroke engines. At the same time, there is a good surface tension of the oil film, the rapid launch of the motor, a decrease in vibration and noise during operation.
STIHL HP oil is also released with sufficient viscosity-it reliably covers all the elements of the 2-stroke engine and does not flow into the pallet if the temperatures are approaching extremely high, but does not freeze if they are lowered below zero. Lubrication effectively neutralizes the negative impact of low.quality fuel, extends the replacement period, which makes the use of garden technology as a whole more economical and reliable.
