How much should you pour oil in a trimmer for grass?
When determining how much you need to add oil to gasoline for a trimmer for grass, use a standard proportion. For one liter of gasoline, 1000 ml is divided into 50, and a 20 ml of oil is obtained. If the poured volume is 500 ml, then the amount of lubrication is reduced in proportion to.
In most cases, trimmers working on gasoline, the existing tank is designed for a volume of 0.5-1.5 liters. Depending on this, the weight of the tool may vary significantly, as well as the duration of work. It can be a maximum of forty minutes.
Lubricant system of two.Stroke and four.Stroke engines
Four.Stroke engines are equipped with separate lubrication systems and preparation of the fuel mixture.
Therefore, the pump supplies oil directly to the rubbing surfaces, that is, the crankshaft bearing and the place of contact of the piston with the walls of the cylinder.
To do this, the lubricant is poured into a special container, from where it comes to the channels to the areas of increased friction.
In addition, through the crankshaft and connecting rod, the oil enters the piston and washes it, reducing the temperature and lubricating the walls of the cylinder.

Two.Stroke engines are deprived of a separate lubricant system, but they also have a crankshaft bearing in need of reducing friction force.
In such power units, the fuel mixture first enters the crankcase, where the crankshaft bearing is located, and then under the influence of discharge passes by the piston, cooling it and lubricating the cylinder walls, enters the combustion chamber.
However, gasoline does not have lubricating properties, therefore, such devices are seasoned with a gasoline mixture, that is, with liquid combustible, to which a special oil was added.
The efficiency of the lubricant with the fuel mixture is much lower than with engine oil, so the life of the bearing of a two.Stroke engine, which means the crankshaft and connecting rod, is noticeably less than the same part of the four.Stroke engine.
In addition, a two.Stroke lubrication system makes special requirements for the oil, because it should burn as much as possible in the cylinder and form a minimum of toxic substances.
What gasoline to fill
Gasoline for a trimmer for grass must be selected unhealthy with an equal number of 92 or 95. As practice shows, AI-80 gasoline can lead to breakdowns of the device, which is a dubious savings.
The fuel should be fresh, that is, after buying it can be stored for no more than 60 days.
Other factors are affected by the quality of fuel, for example, the use of a special lubricant for the lawn mower and its breeding in a separate container. It is also recommended to use special canists designed to store gasoline.
Oil for gasoline trimmers: types and recommendations for use
Gasoline trimmers for grass are one of the more favorite devices for mowing grass. They are ordinary in use, mobile, allow a person to not depend on the outlet and demonstrate amazing results in places of their own implementation. But for the measured operation of a gasoline trimmer for grass, high.Quality consumables are needed. Namely, we are talking about gasoline and oil. Specifically about the last component and talk in this article.
High.Quality oil, which can be poured into a gasoline trimmer for grass, must comply with a number of requirements and norms in order to ensure reliable operation of the device and its performance. Oil should:
- Ensure an increase in wear resistance for different parts (namely, the gearbox is especially susceptible to this);
- Provide a very low formation of smoke and exhaust gases;
- Do not allow early ignition to be carried out;
- Mix perfectly with gasoline when exposed to low temperatures;
- Have excellent characteristics of viscosity and fluidity in different temperature spectra;
- Be as safe as possible based on the beliefs of environmental impact.
As already mentioned, oil for a two.Stroke engine will differ from the compositions for four.Stroke. He has a higher power, which is why fuel for him comes out as a result of mixing a certain amount of gasoline and oil. For each motorcycca, the ratio will be its. You can find out its value in the annotation to the device. These proportions are required to be observed with the greatest accuracy. When adding additives, it is necessary to take into account the type of motor.
If mineral oils are used, then the mixing should occur in some places in a ratio of 1: 25, 30 or 35, depending on the type. If we are talking about a synthetic analogue, then the proportion will be 1: 50 or to 80. In other words, a certain amount of oil dissolves in the volume of gasoline.
Recommendations for storing the finished fuel mixture for a trimmer for grass
After refueling a trimmer for grass, many put off the mixture remaining in the bottle until the next time. Sometimes this next time does not come soon, and stretches until next year. It is impossible to store the finished mixture for so long, since the decomposition of the oil occurs. After preparing the mixture, it must be consumed for 1-2 weeks. In addition, it is also impossible to store the tool for a long time with a fuel mixture flooded into the tank, since the effect will be similar. To prevent unforeseen circumstances, it is recommended to take into account the following recommendations for storing the finished mixture of gasoline with oil:
- Prepare the fuel mixture in such an amount that will be used. If you do not know how much fuel you use, then it is better to cook less
- If in the tank of a trimmer for grass (when the tool is hidden until the next season) there remains a fuel mixture, then it must be fully consumed or drained
- Before adding the cooked mixture to the tank, you need to thoroughly stir it
- Store the finished mixture in a tightly twisting container, as well as in a place limited to the effects of sunlight
Subject to all recommendations, the service life of a trimmer for grass will be no less than indicated in the instructions. The use of qualitative consumables in pairs in compliance with the recommendations for the preparation of the mixture in the trimmer for grass will entail a long and effective service of gasoline tools.

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:
- For motoblocks, motorcycle, mopeds chilled by air. That class;
- Engines cylinder volume 200 cm³. Class TV oil;
- For all.Terrain vehicles and motorcycles, it recommends the use of vehicle oils;
- Yacht engines, hydrosurge cores, motor boats use the cube lubricant TD brand.
From the above list, the lubricant motor fluid of the last two positions is not recommended to use trimmers with power plants. The letter designations indicate from which oil products a lubricant is made.

Attention: If you buy a product at liquid domestic trading floors, be interested in the designations on the container. English words Self Mix say that independent mixing with gasoline is not required. If there is a PRE MIX phrase on the label, you should prepare a combustible mixture yourself.
How to prepare a fuel mixture for a trimmer for grass
But such results are real if you know exactly how much oil is added to gasoline for a garden trimmer for grass. The fact is that two.Stroke engines operate on a mixture of gasoline with butter. The fuel enters the cylinder, burns there, creating a working effort on the piston, and that part of the oil that did not have time to ignite, lubricates the moving parts of the piston group. When preparing a mixture for a trimmer for grass to a liter of gasoline, it is necessary to add a strictly defined amount of oil. If there is too little lubrication, then the friction force will become too large and the motor will jam, and in the case of too much, the oil will fill the candle and the engine will staller. Also, with excess oil, the engine power will decrease, it will not develop the required revolutions and smoke much.
When compiling a fuel mixture, it is necessary to calculate how much oil is needed per liter of gasoline, based not only from the standard proportion, but also from which brand of gasoline and oil is used. In the case of two.Stroke engines, it is very important.
Two.Stroke oil requirements for chainsaws
High.Quality two.Stroke oil for chainsaws should completely burn without the residues of ash or soot, while highlighting a minimum of smoke. High anticorrosion properties and thermo.Oxidative stability can provide maximum engine protection both in working condition and during the period of downtime. The composition of effective oils for the engines of chainsaws, motorcycle or motor cultivators must include certain additives to increase viscosity and solvents that will contribute to better mixing with gasoline. An important requirement for the quality of modern two.Stroke oils is their environmental safety.
For trimmers, a special two.Stroke oil is made, on the package of which there should be a note “2t”. Car, and even more so, transmission oil is strictly prohibited. Two.Stroke oil in three types is produced:
It all depends on what substances make up the oil base. Mineral oil is the cheapest and unreliable. Its use is justified only in household class trimmers, which work for 30-60 minutes a day with large interruptions. Most manufacturers of motorcycles of this level indicate that TS-W3 class oil is suitable for the engine. This means that you can use mineral, synthetic and semi.Synthetic oil 2t.
It is advisable to buy only those grades of oil that the manufacturer recommends for a professional class motorcycle. This is usually semi.Synthetics and synthetics with special additives. Manufacturers mark the oil in letters:
- That. For two.Stroke engines with a volume of up to 50 cubic centimeters;
- TV. For engines 50. 200 cubic centimeters;
- TS. For engines of motorcycles, snowmobiles, etc.D.
In motorcycles, if the type of oil is not indicated in the instructions, you can fill in all three modifications. How much oil is added to the fuel of the trimmer for grass depends on the brand of the tool and the quality of gasoline. Also, on the packaging with butter, the letters FA, FB, FC, etc. May occur.D. They show the level of smoke. The closer the second letter to the beginning of the alphabet, the more smoke stands out during combustion. As a rule, high.Quality oil has very little. This indicator does not affect the choice of oil. Important than the inscriptions “Self Mix” and “Pre Mix”. The first phrase means that the oil dissolves independently, and the container with the second mixture must be shaken several times. The best oils in the market are STIHL, Shell Helix Ultra, Oleo-Mac, Lukoil.
How much oil is needed for 20 liters of gasoline?
For a liter of gasoline you need 20 ml oil. Oil proportion
|1:50||1 l.||20 ml.|
|1:50||one.5 l.||30 ml.|
|1:50||2 l.||40 ml.|
If you are not sure of the “brondium” oil, if the characteristics written on the canister cause you distrust, mix oil and gasoline in a ratio of 1:33. To make the operation more convenient, buy a 20 gram syringe in a pharmacy, if it is stretched to full, it turns out 30 grams. What we need for a liter of gasoline.
