How much oil to add to gasoline for lawn mower?

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

There are two main types of grass trimmers on sale: electric and gasoline. The first one is inconvenient by the fact that, 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, and, just as importantly, much more powerful.

In order to find out what the proportion of oil to add to the mower, 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, you can 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. The oil is semi-synthetic or synthetic, required for two-stroke engines. Gasoline must be at least Ai-92.

Do not mix the liquids in the fuel tank, but in a separate container. Pour the gasoline, add the oil and stir the mixture well for one or two minutes. Only after that can you put it in the tank.

And remember that without oil, the engine will quickly break down. But do not add a lot of oil either, as engine parts quickly become covered with carbon deposits and it can also fail.

How to Dilute Gasoline and Grass Trimmer Oil

Dilute gasoline for grass trimmer must be in the correct proportion. Not enough oil can lead to poor lubrication of the lawnmower’s elements, which contributes to quick wear and tear. oil means more soot on the pistons and spark plugs. Soot on the moving parts of the engine interferes with normal operation and leads to early engine damage.

To find out what ratio is required for your particular model of grass trimmer, refer to the instruction manual provided with the trimmer. 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, 20 ml of oil should be added to 1 liter of gasoline. The table helps you choose the right oil ratio.

To correctly measure the proportions, use measuring containers with a milliliter scale. For this purpose, a special double-neck canister is excellent for mixing and storing oil and gasoline. For example, oil can be drawn in with a medical syringe without a needle. Before mixing liquids make sure that there is no water, dust or dirt particles in the tank for the ready fuel mixture.

It is unacceptable to dilute petrol with the lubricant directly in the fuel tank, and the proportion of oil and petrol must be strictly observed. If you ignore this rule, then the work of the grass trimmer engine can be unstable, due to which it will quickly fail.

It is not advisable to use plastic bottles or canisters for this purpose. This is because gasoline tends to dissolve plastic, which means that some of the plastic can get into the fuel tank, which can lead to carburetor failure. Although there are special plastic canisters marked “flame”.

  • gasoline;
  • Oil suitable for two-stroke engines with air cooling system;
  • canister, preferably made of metal;
  • The tank for mixing, it is also better metal;
  • gloves;
  • respirator.

In addition to protective equipment, do not forget about fire safety rules, because gasoline and motor oil are easily flammable:

  • it is better to work outside to avoid accumulation of petrol vapours in the room;
  • do not smoke and do not create situations associated with the emergence of sparks.

Make a mixture of gasoline and oil as follows:

  • Pour 1 liter of gasoline into a container, add half of the oil you need. Mix thoroughly, do it very carefully away from sources of open flame.
  • Add the rest of the oil to the grass trimmer gasoline and mix thoroughly again. Now you can add oil to the fuel tank of your rotary 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 to suffice for several uses.

For dilution you can use only quality oil, and it is recommended to buy it only in trusted stores, such as specialized hypermarkets.

Oil

For trimmers made a special two-stroke oil, the packaging of which should be marked “2T”. It is strictly forbidden to use motor oil, especially gear oil. There are three types of two-stroke oil:

It all depends on what substances make up the oil base. Mineral oil is the cheapest and most unreliable. Its use is justified only in household trimmers that operate for 30 to 60 minutes a day with long breaks. Most brushcutter manufacturers at this level indicate that TC-W3 oil is suitable for the engine. This means that you can use mineral, synthetic and semi-synthetic 2T oil.

For professional-grade brushcutter it is advisable to buy only those oil brands recommended by the manufacturer. Usually semi-synthetics and synthetics with special additives. Manufacturers label the oil with letters:

  • TA for two-stroke engines up to 50 cubic centimeters;
  • TV. for engines 50. 200 cc;
  • TC for motorcycle engines, snowmobile engines, etc.д.

All three types of oil can be used in brushcutters, if not listed in the manual. How much oil to add to grass trimmer fuel depends on the tool brand and gasoline quality. Also on oil package there may be letters FA, FB, FC, etc.д. They show the level of smokiness. The closer the second letter is to the beginning of the alphabet, the more smoke is emitted during combustion. As a rule, a quality oil has very few. This does not affect the choice of oil. important than “self-mix” and “pre-mix”. The first word means that the oil dissolves on its own, and the container with the second mixture must be shaken several times. Best oils on the market: STIHL, Shell Helix Ultra, Oleo-Mac, Lukoil.

Fuel mixture preparation for 2-stroke engines of trimmers and brushcutters.

According to statistics, more than 50% of the breakdowns of two-stroke engines trimmers and brush cutters associated with the use of low-quality fuel mixture. Fuel for two-stroke engines is a mixture of gasoline and oil, fed into the engine through the carburetor in the form of gasoline-oil mist and provides lubrication of the bearings and piston group. Since in the process of work of the two-stroke engine oil burns together with gasoline, the requirements to such oil differ significantly from the requirements to the engine oil used in four-stroke (for example automobile) engines. First of all, oil for 2-stroke engines should burn as completely as possible without leaving soot, provide good lubrication at high temperatures, have good solubility in gasoline. Oil that does not fully burn leads to soot deposits on the piston, in the cylinder combustion chamber. Cylinder exhaust window. Carbon deposits can flake off, get between the piston and the cylinder walls and work as an abrasive, rubbing off the coating and making “scuffing.

Given the high demands placed on modern two-stroke engines, many major trimmer and brushcutter manufacturers. like STIHL or Husqvarna are testing, formulating and producing their own brands of oil. By carefully selecting additives to the base oil, manufacturers have provided excellent engine lubrication at high speeds and temperatures, significantly reduced the flash point of oils and as a result the most complete combustion.
