Oil to gasoline ratio for lawnmower

How to dilute gasoline and oil for grass trimmer

Dilute petrol for grass trimmer in the right proportion. Not enough oil can lead to poor lubrication of the elements of the lawnmower, which contributes to rapid wear. If you use more oil than is allowed, it will cause soot deposits on pistons and spark plugs. Soot on the moving parts of the engine interferes with normal operation and leads to early motor failure.

What proportion is required for a particular model of grass trimmer can be found in the enclosed instructions. The most common mixture used for 2-stroke gasoline mower engines is a 50:1 fuel mixture, where 50 is part gasoline and 1 is part oil. That is, you should add 20 ml of oil to 1 liter of gasoline. The table is a helpful guide to choosing the proper ratio.

To find the right ratio, use containers with a milliliter scale. A special double-neck canister is excellent for this purpose and is designed for mixing and storing oil and gasoline. For example, you can draw in oil with a hypodermic needleless syringe. Before mixing fluids, be sure there is no water, dust, or debris in the container for the ready-to-use fuel mixture.

Diluting petrol and lubricant directly in the fuel tank is not permitted; moreover, the proportions of oil and petrol should be strictly observed. If you ignore this rule, the work of the grass trimmer engine 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 plastic can get into the fuel tank, which can lead to carburetor failure. Although there are special plastic canisters marked “flame”.

  • petrol;
  • oil suitable for two-stroke engines with air cooling system;
  • canister, preferably a metal canister;
  • The tank for mixing, also better metal;
  • 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 work outdoors to avoid the accumulation of gasoline vapors in the room;
  • Do not smoke and do not create sparks.

Make a mixture of gasoline and oil as follows:

  • Pour 1 litre of petrol into a container and add half of the oil required. Stir thoroughly, do it very carefully away from sources of open flame.
  • Add the rest of the oil to the petrol for the grass trimmer and mix it well again. Now the fuel can be poured into the fuel tank of the grass trimmer.

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

Only high-quality oil can be used for dilution, and it is recommended to buy it only in proven stores, such as in specialized hypermarkets.

Gasoline and Grass Trimmer Oil: Proportion and Use

Gasoline grass trimmers have long been in the use of many dacha owners and owners of homestead plots.

Their convenience is undeniable, because the work does not require a stationary source of power, and the lack of electrical wires allows you to use these devices away from home.

With all this, the devices are quite powerful, among them there are professional models.

Any gasoline grass trimmer requires 2 types of fuel and lubricants (fuels and lubricants) to operate, that is:

However, the principle of operation of two and four-stroke engines of chain saws is different, and this determines how much oil to add per liter of gasoline, and what kind of oil can be poured into the motor.

Why buy grass trimmers?

Comparing with similar mechanisms, give preference to brush cutters in the choice according to the following functional indicators:

  • The mobility and low weight of the unit, which allows you to carry it over distances, to use in hard-to-reach places for mowing.
  • Versatility. Lawn mower is equipped with a node for replacing the working elements while the machine is in operation.
  • Simplicity of design that allows the lawnmower to be used for a long time without frequent adjustments.

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

How to mix oil and petrol for a two-stroke engine

The peculiarity of two-stroke engines is that the fuel is filled into the tank along with the oil. Each filling requires the fuel mixture to be prepared in proportions before operating the equipment. How to do it right? From our article you will learn how to dilute gasoline for a chainsaw, grass trimmer and other garden tools.

How much oil to add to petrol for lawnmower?

Quick answer: the ratio 1:50 (petrol-oil) is usually used.

The word “grass trimmer” has several different meanings. One of them directly refers to electric and brushcutters, varieties of lawnmowers, a tool necessary for mowing the grass. It is a relatively small and yet handy device that helps to cope with grass and bushes.

There are two main types of grass trimmers on sale: electric and gasoline. The first one is inconvenient because, using the device on the site, you need an extension cord, which you have to drag behind you. Electric grass trimmer is devoid of this disadvantage, so it is more mobile, besides, just as importantly, much more powerful.

In order to know in what proportion you need to add oil to the lawnmower, first of all, read the instructions that come with the device. It always says what proportion should be observed. If for some reason the manual is missing, try to find it on the Internet.

Most modern engines run on a mixture that has the same proportion. 1:50. in other words, 20 ml of oil for every liter of gasoline. Oil. semi-synthetic or synthetic, required for two-stroke engines. Gasoline must be no lower than Ai-92.

Do not mix the liquids in the fuel tank, but in a separate container. Pour in the gasoline, add the oil, and give the mixture a good stir for a minute or two. Only then you can pour it into the tank.

And remember that without oil the engine will break down quickly. But you should not add a large amount of oil either, because engine parts quickly become covered with carbon deposits and it can also fail.

Rules of mixing

To prepare the fuel mixture, it is necessary to use a clean and dry container, which does not contain any foreign inclusions or contaminants. Do not use plastic containers. After adding the liquids in the desired proportions, the mixture should be stirred thoroughly for 2-3 minutes. Do not do the following:

  • Adding a small amount of oil directly into the petrol tank of the trimmer, as this will not give a homogeneous mixture;
  • pour the oil in first, and then the gasoline. Because of the difference in densities, this order of adding components also results in a heterogeneous mixture4
  • Measuring out ingredients by eye. With this approach to achieve the exact proportion of gasoline and oil for grass trimmer 1/50 or 1/40 will not be possible;
  • Use bottles made of polyethylene, as the latter is dissolved by gasoline.

Gasoline and oil proportions for the grass trimmer

Gasoline mowers are quite common tools, used by owners of garden and homestead farms for mowing grass and making hay. common tool names are the terms “grass trimmer” and “lawnmower“. The main difference lies in the design of the motor. expensive segment of the devices are equipped with four-stroke models, and cheap. two-stroke. The latter option has advantages, including a small weight, ease of use, as well as a low cost.

The most important condition for the work of two-stroke models is the preparation of the fuel mixture, based on the manufacturer’s defined proportion of gasoline and oil. The simplified design of the motor does not provide a separate channel for lubrication, so engine oil is added directly to the gasoline. Violation of the correct proportion leads to a significant reduction in the resource of the tool and even to its failure. Let’s understand what composition is required for gasoline trimmers, how to properly prepare the mixture and what it can affect.

What kind of gasoline can be poured into the trimmer for grass? To prepare the mixture you need a gasoline of a certain brand AI-95 or AI-92. The brand of gasoline depends on its ignition speed. the octane rating. The lower this figure, the faster the combustion of gasoline and greater consumption.

Usually this ratio is the following norms:

  • 1:25 or 40 grams of two-stroke oil per 1 liter of petrol
  • 1 to 40, or 25 to 30 grams of grease per liter of gasoline
  • 1 to 50. this is added 20 grams of oil per liter of gasoline
Gasoline (liters) 1/25 1/50
1 liter of AI-92 petrol 40 grams of oil 20 grams of oil
2 liters of gasoline AI-92 80 grams of oil 40 grams of oil
3 liters of AI-92 gasoline 120 grams of oil 60 grams of oil
4 liters of AI-92 gasoline 160 grams of oil 80 grams of oil

To know how much oil to add to the lawnmower, it is necessary to get acquainted with the performance characteristics of the product. Proportional ratios, can be represented as follows: 1:25, 1:40 and 1:50, which means 1 part oil to 25, 40 or 50 parts gasoline.
