How Much Oil To Pour In Gas For Trimmer
So, have you finally become the owner of a petrol lawn mower or lawn mower? And your imagination already creates images of how you courageously deal with dense grass. However, the dream of an “ideal lawn” remains a dream when the question involuntarily arises: which oil to use and what are the proportions of mixing it with gasoline?
You can find a lot of information on the correct preparation of the fuel mixture on the Internet. This topic is actively discussed in forums and other thematic resources. But, despite such an active discussion, there are many inconsistencies that we have to deal with.
Actually, it doesn’t matter what technique is used, it can be a lawn mower, lawn mowing or chain saw, they are united by one. two-stroke gasoline engine. Unlike 4T, it does not have an oil sump. For its nutrition, it is necessary to prepare a special fuel mixture consisting of gasoline and oil. The resulting liquid is fed directly to the engine (carburetor). During use, all actively working parts are carefully lubricated, contributing to trouble-free operation under any operating conditions.
Lawnmower Engine Oil
Depending on the chemical composition, lubricants are divided into the following main groups:
Mineral They are made on the basis of oils obtained from petroleum distillates. They are highly viscous and require frequent replacement. The material is intended for low power equipment with an air cooling system. It is recommended to use in warm weather.
Semi-synthetic. They represent a kind of "golden mean". They are based on a mixture of mineral and synthetic oils. Such grease can be used in 2T and 4T engines, landscape gardening and other equipment with air and liquid cooling.
Synthetic. They are made on the basis of special synthetic components containing esters. Differ in low viscosity and long term of operation. They can be used year-round, regardless of temperature conditions. Ideal for complex machinery designed to work in harsh environments with constant variable performance.
Thanks to its 20% solvent composition, any two-stroke oil mixes well with fuel and has the characteristic of complete combustion. The second characteristic feature of them is the color, which can be green, red or blue. Of course, this does not mean that some lubricant is better, and some worse. This is done solely so that it is convenient for the user to distinguish oil from pure gasoline.
Motor oil classification:
The required oil parameters for 2T engines are specified in the requirements of API TC JASO FC, API TC JASO FC ISO GD and API TC JASO FC E-GC. The most widely used classification system API. Based on this, 2T engine oils are divided into 4 large groups:
TA. suitable for household appliances with an air cooling system and an engine displacement of not more than 50 cm3.
TB. it is used for more powerful equipment with an air cooling system and an engine capacity of 50. 200 cm3.
TC. It is used in technology with high demands on oil quality. It is a high-performance lubricant for two-stroke engines with a volume of 50. 200 cm3. Great for lawn mowers, lawn mowers, trimmers, chain saws and other garden equipment.

TD. for outboard motors with liquid cooling.
The most suitable material for 2T motors of API-TB and API-TC class. However, it is necessary to refer directly to the product passport, where the manufacturer indicates the brand of motor oil recommended for its equipment.
Important! For lawn mowers, lawn mowers and other 2T garden devices, special engine oil is provided for two-stroke engines with an air cooling system and marked "for garden equipment". Do not use lubricant for 2T engines with a liquid cooling system. Oil for boat outboard engines, motorcycles and other equipment is also not recommended.
The ratio of oil and gasoline for petrol scythes: why is accuracy so important?
We all loved to “chew” in childhood, so the process of preparing the fuel mixture is not only simple, but also interesting. First of all, it is worth considering the fact that the proportions of the mixture can be different. It depends on the engine configuration, oil labeling and manufacturer’s recommendations. The fact is that with insufficient lubrication, heating of the cylinder and piston occurs, which leads to shallow tearing of all rubbing surfaces and, consequently, to failure of the cylinder. piston group. Well, in the case of its excess, on the contrary, we get coking of the piston ring and the formation of a large amount of soot.
And even despite the fact that there is a generally accepted mixture ratio of 2% (for each liter of gasoline 20 ml of lubricant). The proportions in the mixture are still recommended to withstand accurately.
How much oil to pour in gasoline for a brushcutter?
Everything is quite simple, subject to the right balance, the engine runs in full, all parts are carefully lubricated and not abraded. As a result, we get confidently working equipment that will last more than one season.
To know how much oil to add to the brushcutter, you need to familiarize yourself with the operational characteristics of the product. Proportional ratios can be represented in this form: 1:25, 1:40 and 1:50, which means 1 part of oil for 25, 40 or 50 parts of gasoline.
1 liter of gasoline = 1000 ml
To determine the required amount of oil for a ratio of 1:25, you need 1000/25 and we get a proportion of 40 ml.
We perform the same actions to a ratio of 1:40 and 1:50:
1:40 (per 1 liter of gasoline 25 ml of oil)
1:50 (per 1 liter of gasoline 20 ml of oil)
In order for the proportion of oil for the brushcutter to be observed correctly, it is recommended to use a special measuring container (not plastic). Exclude a possibility of hit in a fuel mix of dirt and water. this may affect its quality. It’s better to start cooking the mixture with gasoline. Pour it to the desired mark, then add oil. A pair of tank slopes are enough for mixing. The liquid quickly connects and takes on a uniform shade, which, depending on the structure of the oil, may be red, green, blue or another. Then the correctly prepared mixture is poured into the fuel tank of the equipment.
Before using the equipment, make sure that the tank cap is tightly closed. If you have more fuel, then the remainder can be stored in a special can or mixing container (no more than 14 days). It is recommended to drain fuel that has not been used up to the end.
Important! Be sure to follow safety instructions. Mix liquids in an open area so that caustic gasoline fumes do not accumulate in the room. Wear gloves and long sleeve clothing. Do not smoke or set fire to anything.
AI-92 octane gasoline is considered the most popular type of fuel for two-stroke engines. Due to the relatively low cost, it is extremely rarely falsified. Therefore, not one hundred percent, but you can be sure of its quality. It is also permissible to use a fuel grade AI-95.
As for the storage of fuel, its period should not exceed 3 months. Over time, gasoline loses its properties, the resin content becomes higher and a polymerization process occurs, which adversely affects the combustion chamber. The fuel mixture for benzokosa made from low-quality materials, settles in the form of soot, as a result of which the main components and systems of the engine suffer.
Recommendations for use and storage
The fuel is ready, filled in the fuel tank, the first spurt and the long-awaited start. However, if you want the equipment to work as long as possible, it is recommended that you first run it in. In order to avoid overheating of the engine, it is recommended to adhere to an average load. After the main elements of the system are carefully lubricated, the load can be increased.
Certain rules should also be followed when preparing the braid for off-season storage:
Drain remaining fuel from the fuel tank and run the final run until the fuel is completely depleted. Then, suspend operation and make sure that the engine is completely cool.
Carefully twist out the spark plug and add about 5 ml of lubricant. Pull the starter handle slowly so that the oil is evenly distributed inside the engine. After that, return the candle to its original state. Store the equipment in a cool, dry place.
