How to Dilute Proportional Trimmer Oil
Trimmer, or lawn mowing – a tool that can not be done in the household. At the same time, its reliability, efficiency and long service life depend on many factors. For example, the quality of fuel. This means that you need to choose the right oil for the trimmer, observe the proportions when adding to gasoline and the rules for refueling the device.
Which oil to choose
For the effective operation of the trimmer, it is necessary to select oil for two-stroke engines. This is due to the lack of an oil sump in such a device. The following classification is distinguished depending on the chemical composition of the oil:
- Mineral – based on petroleum distillate, suitable for low-power equipment and with an air type of cooling, but requires frequent replacement and can only be used in good weather in the warm season;
- Semi-synthetic – suitable for garden equipment with air and liquid type of 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 feature of complete combustion. For the trimmer, it is recommended to use a lubricant that is suitable for devices with an air cooling system. Most often on the package it is indicated that the oil is intended for gardening equipment and is marked TA, TV or TS. Moreover, the last of them is most preferable.
If the consumption of engine oil during the summer season is planned to be large due to the presence in the garden arsenal of a chainsaw, brush cutter, lawn mower, it is advisable to buy 5 liters of oil at a better price. If it is necessary only to mix with gasoline and fill a single tool, then 1 liter will be enough.
Often, manufacturers of lawn mowers produce the right oil, so you can make your choice easier if you select the appropriate brand fluid.
What kind of gasoline to fill
Gasoline for the trimmer must be selected unleaded with a stroke number of 92 or 95. As practice shows, AI-80 gasoline can lead to damage to the device, which is a dubious saving.
The fuel must be fresh, that is, after purchase it can be stored for no more than 60 days.
Other factors affect the quality of the fuel, for example, the use of a special lubricant for lawn mowing and diluting it in a separate container. It is also recommended to use special canisters designed to store gasoline.
How to dilute gasoline with trimmer oil
It is necessary to breed gasoline for the trimmer in the correct proportion. An insufficient amount of oil can lead to poor lubrication of the lawn mowing elements, which contributes to rapid wear. In the event that the oil is more than expected, soot forms on the pistons and spark plugs. Carbon deposits on moving parts of the engine interfere with normal operation and lead to a speedy engine breakdown.
What proportion is required for a particular trimmer model can be found in the attached instructions. Most often, for 2-stroke gasoline engines of lawn mowers, the fuel mixture is used in a ratio of 50: 1, where 50 is part of the gasoline, 1 is part of the oil. That is, 20 ml of oil should be added to 1 liter of gasoline. The table will help you choose the right ratio.
To measure proportions correctly, use measuring tanks with a milliliter scale. For these purposes, a special canister with a double neck is perfect, it is designed for mixing and storage of oil gasoline. For example, oil can be filled with a medical syringe without a needle. Before mixing liquids, make sure that the tank for the finished fuel mixture is free of water, dust and particles of dirt.
Diluting gasoline with lubricant directly in the fuel tank is unacceptable; moreover, the proportion of oil and gasoline must be strictly observed. If you ignore this rule, then the operation of the trimmer motor may be unstable, because of 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 has the ability to dissolve plastic, which means that part of the plastic can get into the fuel tank, which can lead to damage to the carburetor. Although there are special plastic canisters marked “flame”.

This will require:
- Oil suitable for two-stroke engines with an air cooling system;
- Canister, better metal;
- Mixing tank, also better metal;
In addition to protective equipment, do not forget about the fire safety rules, because gasoline and engine oil are highly flammable:
- It is better to carry out work on the street in order to avoid the accumulation of gasoline vapors in the room;
- Do not smoke and create situations associated with the occurrence of a spark.
A mixture of gasoline and oil should be made as follows:
- Pour 1 liter of gasoline into the container, add half the right portion of oil. Mix thoroughly, do this extremely carefully away from sources of open flame.
- Add the remaining oil to the trimmer gasoline and mix thoroughly again. Now the fuel can be poured into the trimmer’s fuel tank.
The mixture can be stored for no more than three months, so it is better to dilute gas in such quantity that it is enough for several uses.
How and how much to refuel
Refilling the trimmer fuel tank is easy. To do this, place the tank so that the lid is placed on top. The amount of fuel depends on the trimmer model. This information is indicated in the instructions, there is also a mark on the tank directly.
This can cause the fuel to spill over into the inlet pipe and fuel filter, which can cause engine damage or ignition of the fuel.
When refueling the trimmer, the following safety precautions must be observed:
- Try to fill the liquid so that it does not spill, you can use a watering can for this;
- If the gasoline spills, then immediately wipe it off;
- Trimmer start should be started after the fuel tank is removed in a safe and secure place, preferably at a distance of more than 10 meters;
- With a long break between operations, drain the remaining fuel.
The correct proportion and adherence to mixing and dressing technology will help extend the life of the trimmer. In this case, it is recommended to choose only a quality product of the corresponding brand.
The chainsaw engine is the "heart" of the tool, so it is very important to use a properly prepared fuel mixture.
Fuel mixture for a chainsaw It is prepared from two components – oil and gasoline. Chainsaws are equipped with two-stroke engines, so the oil is not added to the lubrication system (like a four-stroke engine), but directly to gasoline. At the same time, it is very important to observe the correct proportions of the ingredients, of course, in no case try to work on pure gasoline, because in this way you will very quickly “kill” the chainsaw.
If we talk about which gasoline to pour into a chainsaw, it will optimally use fuel with an octane rating A-95, in this case, fuel economy can turn out disastrously. Often, European manufacturers indicate that A-90 or A-92 gasoline can be used, but in post-Soviet countries the quality of gasoline is inferior to European, so in our realities it is better to use better gasoline.
As for the most proportions of a benzo-oiled mixture, then everything is simple: you must follow the instructions for the tool. All manufacturers of chainsaws indicate the necessary ratio in the instruction manual or in the instrument passport, in addition, the proportions for refueling the chainsaw may differ depending on the model of the chainsaw. As a rule, the proportion of oil and gasoline to a chainsaw of famous manufacturers is a ratio of 1:40 or 1:50, which means 1 part of oil for, for example, 40 parts of gasoline. Now arithmetic 1 liter of gasoline = 1000 ml of gasoline, divide by 40 and get 25 ml of oil. If you perform the same steps to the ratio 1:50, then we get 20 ml of oil per 1 liter of gasoline. As for budget-made Chinese chainsaws, the situation is slightly different. The ratio of gasoline and oil for chainsaw made in China 1:25, that is, 1000 ml of gasoline is divided by 25, we get 40 ml of oil. The thing is that in branded chainsaws a good assembly and the distance between the pistons and cylinders in the engine is much smaller than that of Chinese chainsaws, therefore the required amount of oil differs almost twice.
In order to measure the correct portion of oil, use a regular medical syringe of sufficient volume.
Another subtlety – In a dry canister for gasoline, first fill in gasoline, and then oil. On the contrary, the procedure is fraught with a poor quality fuel mixture, because the oil is more dense, sticks to the bottom of the canister – what a good mix.
Be sure to prepare the fuel mixture in a can and pour ready-made special fuel into the gas tank! Never cook or mix directly in the fuel tank of a chainsaw!
If the question of how to breed gasoline for a chainsaw figured out, then on storage conditions and shelf life of the fuel mixture It is worth saying a few words. It’s best and easier to prepare a 1-liter gasoline-oil mixture, it is recommended to do this immediately before working with the tool. The fuel tanks of chainsaws have a volume of 0.3 to 1 liter. In domestic use, in one session, the entire volume of the prepared combustible mixture is rarely used, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special canister for gasoline, in a dry, dark place. It is optimal to calculate that shelf life of the finished mixture will be 7-10 days. The fact is that the oil currently on the market is not synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.
At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool stalls (so that the saw has a dry carburetor) and now you can leave it until the next operation session.
Unsuitable fuel mixture must be disposed of.
