What gasoline to pour into a lawn mower

The owner of a brand new lawn mower may be confused before using a gasoline unit for the first time. The question faces him: “What gasoline to fill in the lawn mower?””. To figure it out, you need to know some nuances, for example, what type of motor is on the device.

Four.stroke and two.stroke engines differ. A certain fuel is suitable for each of them. At the same time, the two.stroke engine should also be poured with gasoline. Another equally important question that interests the owners of garden equipment: “What oil to pour into a lawn mower?””. This also has its own characteristics.

Refueling of equipment

What gasoline to use

Gasoline for the lawn mower is suitable for a regular car, which is traded at all gas stations. Some models are equipped with a motor operating mainly on a diesel engine, but there are quite few of them. Usually gasoline equipment is sold in shopping centers.

The instructions of each unit indicate the recommended brand of fuel, which should be poured into a gas tank. Therefore, it is important immediately after the purchase to carefully get acquainted with the operational manual. This will relieve many problems and extend the life of the equipment.

It is usually recommended to use gasoline for a lawn mower what has octane numbers 92 and 95. It happens that it is proposed to refue the tank with the AI-98 brand.

Additional Information. The higher the octane number, the higher the stability of gasoline for detonation. Manufacturers achieve this by adding various chemistry to fuel. Therefore, the reverse side of the medal here is an increased duration of combustion in brands with a high octane number.

Technology manufacturers create cars with details that have different tendencies for detonation. That is why its gasoline is suitable for each technique. There is no one general recommendation for a motor with a four.stroke engine or two.stroke gasoline brand. It all depends on the manufacturer and his advice.

If you neglect the instructions and use the fuel stored in the garage, but not suitable for the unit, this will lead to the following faults:

  • Nar will appear on candles, cylinders;
  • The piston system will become unusable;
  • The engine will constantly overheat and work unstable;
  • The power of the equipment will fall and.

How to refuel

It is important not only to figure out what kind of fuel to refuel into the tank, but also how to do it competently. Depending on the type of power plant, a refueling method is selected. Internal combustion engines are of two types:

Each of them has its own characteristics. The main difference is in the working cycle. In the first case, the piston for the cycle manages to make two moves, in the second case. four. Four.stroke. less expensive in gas, oil and more environmentally friendly. This motor element produces a smaller amount of exhaust gases. It is more powerful. In turn, in a small area, you can use equipment with a two.stroke engine. Such models are simpler and are cheaper. Trimmer for grass, like a lawn mower, has similar types of engines.


In order to refuel this unit, fuel should be prepared. Pure gasoline is not suitable here. It must be diluted with oil. The fact is that two.stroke engines do not have an additional oil container, so the oil is poured into the engine with gasoline.

Lubrication should be enough. If you save on it, then the piston will be difficult to perform a working cycle. The cylinder and the piston wheel will ultimately damage. This will lead to the replacement of the engine. If, on the contrary, pour too much oil, then the piston will be covered with soot, and the power of the equipment will decrease many times.


Such an engine has a complex design. In addition to the tank, there is also a special oil container. It is called Carter. During operation, fuel and lubrication come in the necessary proportions to the motor. The advantage of a four.stroke engine is that there is no smell of burning oil, like a two.stroke engine, here does not happen.

In the tank for fuel, it is necessary to place high.quality pure raw materials provided for this brand unit. This is usually AI-92 gasoline, AI-95. Should be seasoned as necessary. There is a mark in the gas tank to which the liquid is poured. If it is absent, then the container is filled with a combustible unit. It is important to leave a little free space. Otherwise, the engine operation will be violated.

Oil for a mower

Select suitable oil for garden equipment should be taken into account the technical characteristics of the machine. The oily fluid is necessary in order to be on the nodes, to spread in the spaces between the details and on the details themselves, providing them with a slight sliding. Thus, the wear of the technique will be minimal.

note! Oil for a lawn mower with 2 stroke engine is categorically not suitable for an apparatus with 4 stroke motor. Due to confusion, you can lose the guarantee and break the engine.

According to the characteristics of the 4 x stact oil mushrooms, for a long time should retain its chemical and physical properties, since it does not burn during the operation of the engine, but continues to move along the insides of the mechanism. In turn, the oil for a lawn mower with a 2.stroke engine burns together with the fuel. Therefore, its characteristic includes such a item as the amount of carbon. When operating a quality product, the cargo should be minimal.

Important! You can not purchase car oil. Lubrication for cars and trucks are designed taking into account use in water cooling mechanisms. In lawnmands, like snowmobiles, motor.cultivators, air cooling is used. Due to these differences for garden equipment, manufacturers produce their products. They are focused on air cooling.

For two.stroke engines

For two.stroke engines, lubricants are suitable:

On the packaging there should be a note about the type of engine for which the product is suitable. Often manufacturers of equipment indicate the recommended varieties of lubricants in the instructions for use. The manufacturer advises the brand based on the suitable level of viscosity, which is acceptable to this unit.

For four.stroke engines

For four-stroke engines, oil is suitable, on which there is a marking SAE-30, SAE 20W-50, 10W-30. These numbers and letters indicate a feature of lubrication, or rather its viscosity and permissible weather conditions. The first two options are suitable for work in the summer. The third option is preferred for a cool off.season. It is allowed to use the product under the marking 5W30. This is an all.season liquid. If the internal combustion engine is 4-stroke, then the advantage is given to semi-synthetics or mineral product.

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

Gasoline for a four.stroke engine

Devices with a four.stroke engine have a more complex device. Oil and gasoline are poured into different containers, from where they are then supplied to the engine. For a mower with such a motor, you need gasoline of the AI-92 and AI-95 brands. Applying a fuel with a lower octane number is better not worth.to. This will lead to unstable engine operation. In addition, you can not use a lubricant intended for two.stroke models.

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;
  • respirator;
  • gloves.
  • 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:

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 lubricant 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.

Fuel preparation for two.stroke units

To prepare fuel for a two.stroke engine, it is necessary to mix gasoline with butter in an accurate proportion installed by the engine manufacturer, a ratio of 1:50 or 1:40 is usually valid. Oil should have a 2T or TC-W3 marking, as a rule, it is painted blue. Gasoline should be used only the one that is determined by the manufacturer in the instructions, most often it is A-92.

For preparation, you will need a plastic transparent bottle, on which a fluid level corresponding to a volume of one liter is noted in advance. Then, with the help of a syringe, the volume of gasoline equal to a portion of diluted oil is selected from the bottle. For a mixture with a ratio of 1:50 it will be 20 ml, for a mixture 1:40. 25 ml. After that, the corresponding amount of oil is added to the mixing container and the mixture thoroughly shake.

It is better to cook fuel in small portions and use it immediately. Experts say that due to long contact with gasoline, oil may lose its properties. It must also be remembered that some two.stroke engines have separate oil injection, for them you do not need to prepare the mixture, but be sure to monitor the lubrication level in an additional tank.

Features of refueling motorcycles

When the mixture is ready and ready for use, it must be carefully poured into the fuel tank. Since gasoline is toxic fluid, when working with it, you need to observe safety precautions. Work must be carried out in measured weather and away from third.party people. Also to pour fuel into the tank, you must use a funnel or a funnel with which you have previously diluted the mixture. In an unpleasant case, the mixture may blur, go unnoticed and inflamed when the engine is heated.

The fuel bank itself must be cleaned of external pollution and only then unscrew its cap to refuel it with ready.made fuel. After filling the combustible, the reservoir should not remain open, since insects or soil can get into the tank and clog the fuel filter. The fuel should be poured into the tank of the designated mark either less, and then in the time of operation.

When storing the container, it is necessary to close tightly with a lid. Store combustible in a cold room, outside the sun’s rays. It should be kept in your head that with prolonged storage of consistency, the oil liquefies and loses its characteristics.

The container should be tightly closed during storage. Fuel should be stored in a cool place, in a place where the sun does not penetrate. Remember that with prolonged storage of a mixture, the oil lifts and loses its properties.

Preparation of the fuel mixture

To obtain fuel mixture, motor oil is mixed with gasoline in certain proportions. They are given in the operating instructions. So, mineral lubricants are mixed with gasoline in a ratio of 1 to 35, and synthetic. 1 to 50.

  • Pour the exact amount of gasoline into the canister;
  • Add using a dispenser, the required volume of oil;
  • Close the capacity with a lid;
  • stir the composition, shake the liquid.

The prepared fuel mixture is simply poured into the gas tank, using a watering can.

The proportional ratios encountered between oil and gasoline in the fuel are presented in the table below. It will allow you to quickly decide on the volumes of mixed materials.

You can store the prepared mixture of gasoline with butter in polypropylene or metal containers for no more than two weeks. It is impossible to save the composition in polyethylene bottles. This is due to the fact that gasoline reacts with the material of the container, and the resulting products fall into the working mixture. Because of this, when combustion, the composition will form more than soot.

It is allowed to refuel the fuel mixture only if the motor has cooled down almost completely. At the same time, the tank cannot be poured: you should leave a place for the temperature expansion of the fuel.

What will happen with the wrong refueling and what you can’t pour

What if you pour 95 gasoline instead of 92 and vice versa

It is important to adhere to the manufacturer’s recommendations. But if you pour fuel with a large octane number than recommended.e

pour instead of the 92nd 95th, nothing terrible will happen. Often in the instructions you can see a recommendation in the form of a range, for example, 92-95.

Filling fuel with a smaller octane number (for example, 92 instead of 95) will lead to the following undesirable consequences:

  • the appearance of soot inside the combustion chamber, on the spark plugs;
  • increased fuel consumption, drop in the efficiency;
  • mechanical damage to the pistons and valves;
  • instability in the work of the motor, detonations.

If you pour gasoline without oil

Theoretically, you can start the motor, but it will work for wear, the details will be rubbed against each other and, perhaps, soon the engine will jam from overheating. And even if you are lucky for some time to work with such a mower, then such a load will affect the resource.

If by chance, the device was tucked with clean fuel, then it must be drained and seasoned again, but according to the instructions.

If you pour diesel fuel instead of gasoline

If the diesel fuel is poured instead of gasoline, then the engine is unlikely to start. The “miracle” can happen if gasoline still remains from the last refuel: the diesel fuel will drop lower, and the engine will be able to start, but after a very short time diesel fuel will be involved and the engine stalls stupid.

If the oil is more or less

If there is more than the norm inside the two.stroke engine, then the valve will be clogged with tarry sediments. In such circumstances, the motor will simply be. On the other hand, the lack of lubrication will lead to increased friction, the destruction of rubbing elements.

Thus, a clear adherence to the operating instructions, the use of recommended liquids will extend the service life of the lawn mower.

The choice of fuel

The preparation of fuel for a two.stroke engine is to mix special engine oil (it is bought in the same place as law mowers or spare parts for cars) with gasoline. Mineral oil is mixed with fuel in a ratio of 1 to 32 (or 1 to 35), and if it is synthetic, then the ratio of 1 to 50. all this should be indicated on the packaging. You can cook fuel for the lawn mower for the entire season, for this, 100 g of oil is added to the 5-liter cancer of gasoline.

To the question: “What gasoline to use?”. the answer is simple: the brand should not be higher than the one indicated by the manufacturer of the lawn mower. The octane number is important. the higher it is, the greater the burning time of the fuel, if you use the fuel of a higher brand, this will reduce the operation of your device. The four.stroke engine has a card that contains a lubricant that lubricates the motor, so it is seasoned only with gasoline. But it will have to be changed with a frequency of 50 hours, whatever it may be, since there is no special oil filter.

Only a cooled motor can be seasoned with fuel, and the tank cannot be filled “under the tie”, you need to leave a little space for expansion. Of course, the safety rules should always be observed.

What gasoline to pour into a lawn mower with a four.stroke engine?

Now let’s tell what gasoline to the lawn mower with a four.stroke engine, the main difference of which is the presence of a crankcase. It contains oil for lubricating the motor, because that the device of this type works normally, it is enough to season it only with gasoline. But there are its own characteristics. Because the technique does not have an oil filter, but it means that it is not cleaned, it must be changed about every 50 hours of operation.

As for gasoline, who need to refill the lawn mower, it should not be a higher brand than recommended by the manufacturer of equipment. Since the higher the octane number, the longer the fuel burns. And this, in turn, can lead to significant problems and premature breakdown of the tool.

Everyone knows well that gasoline is a very easily inflammable substance, and its pairs are explosive. Based on this, we recommend always observing several simple rules that will ensure security for each user:

gasoline, stroke, lawn, mowers, operate
  • Before refueling, you need to let the engine cool down.
  • You can not work with fuel if there is open fire nearby, it is also forbidden to smoke.
  • To avoid poisoning with exhaust gases, pour fuel and launch in the open air or indoors with good ventilation.
  • It is not recommended to refuel the tank completely, it is necessary to leave a place to “expand” gasoline, which always occurs when it is heated.
  • Try to so that fuel does not fall on your clothes and shoes.

In general, the maintenance of gasoline engines of the lawn mower is a rather simple business that does not require any special knowledge and skills from you. For units with a two.stroke engine, you need to learn how to prepare the combustible mixture correctly, as well as to clean the air filter in a timely manner. It is enough to change the oil with a four.stroke engine to change the oil and clean the air filter so that it serves you for many years by faith and truth.

How to change oil work for a 4-stroke motor?

For the convenience of replacing in a 4-stroke engine of oil, blackened after prolonged work, a funnel, a pump and an additional canister may be required. Make the following.

  • Heat the engine of the lawn mower by turning it on for 10 minutes. It is better to confuse action to the next mowing of overgrown grass.
  • Substitute the funnel with the canister and remove the drain plug.
  • Unscrew the upper (flood plug). Heated oil faster and better wicker.
  • After waiting until everything is produced, and the remains stop dripping, close the drain plug.
  • Wait for the motor to cool. This will take up to 10 minutes.
  • Pour fresh oil from the new canister, controlling its presence with a probe, and screw the pouring cork of the tank.

Acts to replace the oil in the lawn mower are the same as in the car engine.

The main breakdown of Kustorez

Despite the wide variety of manufacturers and a variety of models, the reasons why Makita, Honda, Husqvarna or other lawn mowers are not launched are the same for all.

The main reasons why the lawn mower does not start and does not stop, but immediately stops, there may be problems with ignition, carburetor, filters.

If the fuel and the fuel mixture are filled with proper quality and quantity, the air damper closes, the mitch is launched and immediately forgot; The reason may be related to the following problems:

  • The spark plug is faulty or filled. In this case, it is necessary to unscrew the candle, thoroughly dry and clean with a file or nail file. Excess fuel is merged, the candle hole is dried. Set the gap 1 mm and the candle is screwed again.

Important! For drying the channel requires at least half an hour.

  • Dry threaded connection. It should be lubricated with gas so that the spark can light up.
  • No candle candle. In this situation, the contact between the candle and the high.voltage wire is first checked. If the contact is normal, and the lawn mower is clamped and retained, there is a problem with the ignition, and you can do without a service center.

These breakdowns are the general reasons why the Huskvarn lawn mower does not start.

gasoline, stroke, lawn, mowers, operate

Common causes of damage to garden equipment, for example, why the Honda lawn mower does not start. These are problems with air and fuel filters:

  • The air filter is clogged. If the first possible causes are not confirmed and the lawn mower is still worth it, you can remove the air filter and try to start the device without it. If the engine starts, the reason is. The filter must be cleaned or replaced by a new.
  • Dirty fuel filter. Another possible diagnosis. The filter element is checked and, if necessary, replaced.

Important! The launch of the lawn mower without a filter element is not recommended.

Subsequent malfunctions are more serious and it is difficult to deal with them. There are problems with the malfunction of the carburetor:

  • Pollution of nozzles and channels. They are washed with special fluids blown by the air flow from the carburetor.
  • Wondered gasket. A new gasket has been replaced.
  • Damage to the leak. Diagnosis is carried out using a tonometer. If the pressure is stable, everything is in order, it falls. you need to find and replace the damaged element.

Another option is the problem with the piston group. Worn or damaged pistons should be replaced.

Recommendations for diluting gasoline oil

The purpose of the oil composition is to ensure the required smoothness of sliding pistons and motor valves. As a result, the wear of the working parts will be reduced to a minimum. Do not dilute gasoline with oil for a 2-stroke engine for a 4-stroke engine, and vice versa. The composition, poured into a tank for 4-stroke engines, retains its “sliding properties” longer. He does not burn out, but manages to spread through the mobile engine details.

In a 2-stroke motor, oil fraction burns along with gasoline-soot is formed. The permissible speed of its formation is one of the most important characteristics of a 2-stroke motor. This means that the engine should not clog their valves with a soil for several spent liters of gasoline.

The motor is designed for a much longer “mileage”. especially when it comes to hundreds and thousands of hundreds of grass, mowed over the season. High-quality butter-Benzine fraction also matters when protecting the motor from the thick layer of soot, which it will be impossible to work with.

The composition of the oil for two- and four-stroke engines- mineral, synthetics and semi-synthetics. On a flask or canister with butter, a specific type of engine is indicated.

The accurate recommendation of the manufacturer refers the consumer to the oil from certain firms. For example, this is Liquimoly manufacturer. But such a correspondence is not necessarily.

Do not buy for the lawn mower automatically. manufacturers produce a special composition. The lawn mowers and snowmobiles are not water, as in passenger cars and trucks, but air. Each model of a benzocystem provides for fuel of certain brands and proportions, which is not recommended to deviate.

Rules for the operation of lawn mowers

Like any equipment, the lawn mower needs some care functions and basic principles of use. These rules are simple, but will help maintain health for a long time.

General operating rules:

  • Read the instructions for operating and caring for the lawnical mower, read the basic rules of operation, storage and safety.
  • Clean the case, ducts, grass collector, knives, preferably with special liquids after each use.
  • Do not clean a hot lawn mower.
  • During operation, monitor the condition of the engine, do not allow its overheating, take breaks.
  • With large intervals in the operation of the lawn mower (about a month), drain the fuel. At the same time, at the end of the work, the device is given the opportunity to stand idle and stand.

Rules for preparing equipment for winter:

  • A visual inspection of the mower is carried out, the main parts were removed, cleaned, dried, damaged.
  • Fuel leaks.
  • The air filter was cleaned.
  • Oil is poured into a transmission.
  • All moving parts of the engine are cleaned and lubricated.
  • The motor wrapped in oiled fabric.

Gasoline gasoline MTD Smart 51 BO

  • Before starting work, the working area is checked for the presence of foreign objects: stones, branches.
  • Outsiders should be at a distance of at least 5 m from the mowing.
  • Work is carried out in special glasses.
  • Visual examination of the lawn mower for damage, untouched parts. The malfunctions are eliminated.
  • You can mow grass up to 20 cm in height, no more than a third.
  • When working on the slopes, you must move up the slope, not up and down.
  • The engine stops before changing the step.
  • If third.party elements enter the knife, the work stops, and not cleaned.

Gas braids have earned the respect of users for their power and quality. To extend the service life and the effectiveness of the device, it is necessary to study all the subtleties of care and care for the lawn, follow the safety rules and follow the instructions for the operation of this equipment.

What gasoline to pour into a lawn mower with a four.stroke engine?

Now let’s tell you what gasoline to pour in a lawn mower with a four.stroke engine, the main difference of which is the presence of a crankcase. It contains oil for lubrication of the motor, therefore, in order for the device of this type to function normally, it is enough to season it only with gasoline. However, there are its own characteristics. Since the technique does not have an oil filter, which means it is not cleaned, it must be changed approximately every 50 hours of operation.

As for gasoline, who need to refill the lawn mower, it should not be a higher brand than recommended by the manufacturer of equipment. Since the higher the octane number, the longer the fuel burns. And this, in turn, can lead to significant problems and premature breakdown of the tool.

Everyone knows well that gasoline is a very easily inflammable substance, and its pairs are explosive. Based on this, we recommend always observing several simple rules that will ensure security for each user:

  • Before refueling, you need to let the engine cool down.
  • Pour only 92nd gasoline (not lower);
  • You can not work with fuel if there is open fire nearby, it is also forbidden to smoke.
  • To avoid poisoning with exhaust gases, pour fuel and launch in the open air or indoors with good ventilation.
  • It is not recommended to refuel the tank completely, it is necessary to leave a place to “expand” gasoline, which always occurs when it is heated.
  • Try to so that fuel does not fall on your clothes and shoes.

In general, the maintenance of gasoline engines of the lawn mower. A rather simple thing that does not require any special knowledge and skills from you.

All of the fuel mixture for a trimmer for grass. What gasoline is needed for a trimmer for grass

The authors answered correctly that there is a big difference in the gasoline brand for two.strokes and a clear.haired. I do not take into account the ethletrimmers. in them, by definition, the lubricants are used only for moving parts of the drive.

Without entering “because of the stove” I can say from my own experience that for two-strokes gasoline should be an actane number for less than four-strokes. There was experience in operating a four-stroke trimmer for Makita grass on 92th gasoline. The owner of the trimmer for the grass again used it on the 92nd, although the manufacturer was recommended by gasoline from 95 and above.

However, he used all other operational fluids in strict accordance with the instructions (oil for the engine crankcase (for crank)) tried to mow on it at one time, and this is what I understood. The result is not a traction to the line, much lower than the declared by the manufacturer, as a result of more revolutions and heating, too, gasoline does not burn completely, the carpet in the muffler is constantly growing.

Having taken him home to drive him, he tucked the 95th gasoline, and the car went-it doesn’t heat up, the receipt is where you are with good, the exhaust is like on a gas-it doesn’t even smell and you can’t see it, you can put your hand on the cylinder and not burn yourself. Conclusion. for four.stroke trimmers, at least 95 gasoline is better.

For two.strokes. There is just the opposite. In what proportions do not dilute 95 gasoline with oil, the additives present in it (and in the definition of the “clean” 95th gasoline at all-this is the same 92 package of additives), it will not be possible to neutralize oil and therefore the detonating component is not excluded not to be excluded.

In addition, the two-stroke, which practices each cycle of the piston to ignite the working mixture, heats up on high-octane gasoline much stronger, as if the combustion temperature is higher. Which leads to an increase in the natural expansion of metals, well, it is completely logical to a decrease in the gap in mating details (piston group, clips and balls of bearings, etc.P.

gasoline, stroke, lawn, mowers, operate

) The four-stroke “practices” every second beat in working mode (ignition of the working mixture) according to the principle of operation of the cooling system, we can also say that the 92nd gasoline is more recommended for two-strokes having an air cooling system.

Oil proportions for any of the type of motors first of all need to look in the product passport. Well, of course, it is clearly aware that the oil is poured into the four.strokes only into the engine crankcase, and for the two.stroke, a working mixture is prepared from parts of gasoline and part of the oil. Proportions for oil and gasoline for each of the models of trimmers need to be watched (first of all!) in the passport of the product.

I can only cite guaranteed oil and gasoline proportions for two-stroke engines of the STIHL and Huter trimmers-both during the time and during operation, when using ours (gasoline, dilute 25 milligrams of oil for each liter of 92th gasoline. The proportion of 40/1 on these proportions I have been working on the 180th STIHL and a trimmer for Huter grass for more than three years-the flight is normal.

gasoline, stroke, lawn, mowers, operate

The proportions of the Stihl manufacturers-50/1 is not for our gasoline, but for the European brand 87-90, which from the distiller come out, without the addition of anti-depth and eco of additives.

Summer residents, owners of private country households for leaving lawns, mowing weed grass, buy small mechanization. They prefer trimmers drive by internal combustion engines, filling a properly diluted mixture of gasoline and oil.

Motorized braids for grass require care, the use of combined fuel. Observing the ratio of gasoline and oil, it is easy to achieve motorcycles.

Comparing with similar mechanisms, they give preference to motorcycles when choosing the following functional indicators:

  • The mobility and small weight of the unit, allowing it to transfer it to distances, use it in hard.to.reach places for mowing.
  • Universality. The lawn mower is equipped with a knot to change working elements directly during the operation of the unit.
  • Constructive simplicity that allows you to use a braid for a long time without frequent tuning.

These, other positive characteristics give customers confidence that when purchasing a trimmer for grass, make the right choice.

How to choose the right proportion?

The lawn mower is seasoned with gasoline A-92 brand. There are other factory instructions requiring gasoline of another octane number. For example, A-95. The difference in cost is minimal.

The selection of oil does not accept liberties. For two.stroke engines, the API establishes a specific order:
