How to fill the trimmer with gasoline and oil

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.

fill, trimmer, gasoline

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 thereby.

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.

For information on the ratio of gasoline and oil needed for lawn mowers, see the next video.

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 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 lawn mower components, which contributes to rapid wear.

The correct ratio can be found in the trimmer instructions. Most often it is equal to 1:25, 1:40, 1:50. To obtain such proportions in 1 liter of gasoline, you need to add 40 ml, 25 ml and 20 ml of oil, respectively.

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”.

How to Mix Oil and Gas: The 2-Cycle Engine Fuel Recipe

This will require:

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

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.

Which oil to choose

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

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

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

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

What gasoline to fill

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

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

Other factors also affect the quality of the fuel, 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.

Consequences of violation of the ratio

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

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

How to dilute gasoline with trimmer oil

Petrol trimmers are ideal for site maintenance thanks to their portability. These models of lawn mowers require periodic fuel changes. The choice of gasoline must be approached competently. It is not worth saving much on the purchase.

Fuel mixture for two-stroke engines

Trimmers that are equipped with a two-stroke motor do not have a separate system for supplying oil to lubricate the rubbing parts. For this reason, such devices should not be refueled with pure gasoline, but with a mixture of fuel and engine oil. The latter must be specially designed for two-stroke engines. Application of automotive engine fluid will result in premature engine failure.

Preparation of a fuel mixture for two-wheel engines

You need to refuel a lawnmower with a two-stroke engine with AI-92 gasoline. When using AI-95, overheating of the engine and uneven operation of the unit can be observed. You need to mix gasoline with oil in a ratio of 50: 1, where 50 is fuel and 1 is oil. It turns out that 1 liter of fuel will require 20 ml of oil.

If the motor is worn out or the tool is under heavy load, then the ratio is 25: 1. If there is little lubrication, then scuffs will appear on the cylinder walls and the piston surface. Then the piston ring will undergo destruction, causing the engine to jam. An overabundance is not so critical, but it can lead to the formation of carbon deposits. At the same time, the piston ring will coke, which will reduce the power of the device.

Ratios of oil and gasoline for the fuel mixture

Choosing a brand of gasoline for trimmers

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

Gasoline for fuel mixture

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

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

Two-stroke and four-stroke

Internal combustion engines used in trimmers are two-stroke and four-stroke. By design, two-stroke engines are simple. But they require a high-quality fuel mixture.

Two-stroke power trimmer gasoline needs a precise dosage of lubricant. Ignoring the requirement leads to a sharp reduction in engine life. There are problems with launching it.

A four-stroke engine does not require the correct proportion of oil and gasoline. Formation of the desired mixture is automatic. The components of the combustible mixture are stored in different containers. The fuel is expensive, but the costs are covered by the silent operation of the unit, the environmental friendliness of the exhaust gases.

Why buy trimmers?

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

  • Mobility and low weight of the unit, allowing it to be carried over distances, used in hard-to-reach places for mowing.
  • Versatility. the lawn mower is equipped with a unit for changing working elements directly during the operation of the unit.
  • Constructive simplicity, allowing long-term use of the braid without frequent adjustments.

These other positive characteristics give customers confidence that they are making the right choice when purchasing a trimmer.

How to refuel the trimmer

A ready-made mixture of gasoline and oil can be stored for no more than 3 months (pure gasoline is stored less). Dilute enough fuel for several trimmer uses. In general, prepare:

  • gasoline and oil that is suitable for two-stroke air-cooled engines;
  • metal canister and mixing container;
  • respirator;
  • gloves.

Dilution instructions:

  • Pour 1 liter of gasoline into a container of suitable volume and add 1/2 of the required amount of oil.
  • Stir gently while keeping a good distance from open flames.
  • Add the remaining half of the oil to the fuel and stir again.

Trimmer refueling process

General tips for refueling a trimmer with a 2- or 4-stroke engine:

  • Place the fuel tank so that the lid is on top, then fill in the required amount of fuel.
  • Do not overfill the fuel tank. This will lead to one of the problems: overflow into the intake manifold and fuel filter, fuel ignition or engine breakdown.
  • Try to pour the mixture so that it does not spill. To do this, you can use a watering can.
  • If you do spill fuel, wipe it up immediately. Dispose of the cleaning material, do not accumulate indoors. it is fire hazard.
  • The start-up of the device should be started after the fuel canister has been removed at a distance of more than 10 m.
  • If there was a long break between the operations of the mower, then the remaining old fuel must be drained.

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.

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

How to choose the right proportion?

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

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

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

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

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

Gasoline for four-stroke engine

Devices with a four-stroke motor are more complex. Oil and gasoline are poured into different containers, from where they are then fed to the engine. For a mower with such a motor, you need AI-92 and AI-95 gasoline. It is better not to use fuel with a lower octane number, because this will lead to unstable engine operation. In addition, do not use a lubricant designed for two-stroke models.

Important feature

The prepared combustible mixture for the trimmer enters the combustion chamber of the cylinder in the form of a whitish mist. The oil integrated into gasoline lubricates the crankshaft and cylinder walls. Failure to add oil to the fuel is fraught with premature wear of trimmer parts and assemblies. Exceeding the norm leads to soot settling on the working parts, which is also fraught with premature technical wear of the lawn mower.

A gasoline mower will serve the owner for a long time, provided that they will not pour any gasoline into the fuel tank, but high-quality fuel.
