to service. In order for the tool to enjoy the trouble-free operation for a long time, it is necessary to use fuel and oil for gas benzers in accordance with the technical operation instructions. Two-stroke gasoline engines operate with the addition of oil to the combustible mixture; four-stroke engines have a separate tank in the fuel tank.
A variety of motor oils, their purpose
Engine oil is a special compound that is a solvent and additives that reduce friction, create the desired fluidity and prevent thickening when the temperature drops.
According to the method of obtaining the composition are:
- mineral, obtained from the distillation of oil;
- synthetic - synthesis or processing of natural gas;
- semi-synthetic - improved mineral oil due to the introduction of synthetic components.
For safety reasons, in order not to confuse the products, the oil is colored red, blue or green. The range differs in composition, the user needs to buy oil with the marking: “for garden equipment” 2T, if you need to prepare a mixture for a two-stroke engine, 4T for pouring into the crankcase.
Synthetic and mineral oils have a different basis, they can not be mixed. When switching to another type of oil, the system should be thoroughly rinsed.
Oil for benzokosy should be classified according to the classification of vehicle oils intended for air-cooled engines with a combustion chamber volume of 50-200 cm3.When choosing a product, the important parameter is not the price, but the protective properties for the engine of a particular brand. Therefore, in the first place, they buy the recommended oil, in the absence of it they select an identical one by the indicators.

Determines the quality of oil for benzokosy base number. Alkali neutralizes the oxidation process of rubbing materials, slows down the destruction of the surface. When the oil becomes oxidized, it loses its protective properties. The normal pH of the oil is 8-9 units.
An important indicator is viscosity. Therefore, it is winter, summer and all-season oil. What kind of oil to use for benzokosy depends on whether the user will work at sub-zero temperatures. Summer oils thicken even with a slight cooling. The flash point indicates how quickly the oil will burn out. Optimally, if this indicator is more than 225 C.
The order of use and the value of oil in a two-stroke engine
The engine operation is associated with the friction of moving parts of the cylinder and liner, cams, hinges. When the parts are rubbed, the surface is heated, and when it is expanded, the scuffing occurs. If the composition in the right proportion of oil and gasoline for gasoline mowers is in the gap between the mating parts, a number of problems are eliminated:
- parts in the engine work with reduced friction, they heat less;
- grease in the gaps prevents corrosion of parts during long-term storage, flushes out particles obtained by friction;
- extends engine life.
The additives used in the oil in the amount of 5-15% contribute to the appearance of additional properties. It is additives that create anti-corrosion, anti-wear and frost-resistant properties of oils.
Incorrect oil composition can destroy the engine, forming carbon deposits in the cylinders, leading to coking and rapid engine wear.
It is important to know how much oil needs to be added to gasoline for mowers. First of all, you should study the instructions, and maintain the recommended proportions. The use of the composition, which takes into account the model and configuration of the engine, the climatic conditions and the load, will prolong the life of the gas mowers. Experienced users advise, when purchasing a tool, immediately buy the recommended oil in reserve.
Combustible mixture requirements for a two-stroke engine
The difference between a two-stroke engine and its increased power compared to a four-stroke one. Combustible mixture for it is prepared in a certain ratio of gasoline and special oil. What is the ratio of oil and gasoline for benzokosy optimal, it is written in the instructions. The recommended proportions need to be observed precisely. When adding additives, the manufacturer took into account the type of engine. Therefore, it is prohibited to mix different oils.

This means that in each of the proposed mixtures the right amount of oil is dissolved in the volume of gasoline. You can mix gasoline with oil for benzocos as water and syrup. It is necessary to pour gasoline, add the exact amount of oil and shake the mixture. For work, it is desirable to use a fresh solution. When stored for more than 2 weeks, the composition changes, and the oil film will cause the carburetor to malfunction.
PET bottles should not be used to dilute and store the combustible mixture. Gasoline destroys plastic, the polymer dissolves in the combustible mixture and further deteriorates the quality of the fuel, creating the danger of stray currents.
The right choice of oil for the
petrol mower. Two-stroke engines are charged with a mixture of unleaded gasoline and oil labeled 2T.Thus it is necessary to use the recommended petrol AI-92.If you apply a brand with a higher octane number, the flash and burning temperature will be higher, the valves will prematurely burn out. The same applies to the oil. The recommended composition is not the most expensive. But the use of another brand is unacceptable. Viscosity will change, this will lead to insufficient lubrication of conventional products made without high-precision lapping.
If the oil is added in excess, incomplete combustion will lead to the formation of soot and excessive exhaust into the atmosphere. A rich mixture is harmful to the engine. For a four-stroke engine oil is poured separately from gasoline. It washes the nodes, cools, reduces friction. In the process, the oil is contaminated and after 50 working hours must be replaced. What oil to pour in benzokosa, indicated in the passport. The composition must be labeled 4T with a viscosity of 10W40.

The best oil for any engine is considered recommended. However, Shel Helix Ultra is world renowned. The company has been engaged in the development of a new technology for the production of synthetic oil from natural gas for 40 years. Pureplus technology allowed for the production of an improved base oil composition. On its basis, with the addition of the necessary additives, get the recommended oils for their equipment leading manufacturers.
The choice of oil primarily depends on the recommendation of the manufacturer. So, oil for benzokosa Smooth use only brand. The same oil is suitable for the Vityaz brand, as the engines in the brands of the same brand. There is an opinion of experts, the oil of any manufacturer, intended for one type of equipment, is suitable for use on all brands. But if possible, it is better to use the recommended.
The stock of oil should be on demand for one season. A product that lasts a long time loses its properties. Packages from 0.1 to 5 liters are on sale.
The path of oil recommended for Husqvarna gas mowers was investigated. The company does not have its own production, only bottling shop. Bought wholesale product is bottled in small containers, marked and enters the distribution network. It is possible that exclusive additives for Husqvarna were added to the composition of the oil at the manufacturing stage.
The use of oil, according to the instruction manual for the mowers, is mandatory. Equipment cannot work on pure gasoline.
