Usually after buying any tool, sooner or later, but still a question appears, and how to care for him. In wise consumers, he arises in the head before the first trouble, that is, breakdowns and repairs. What gasoline to use, what oil for chainsaws to buy, so that it serves a long time and reliably, to pay attention to - this is what we will tell in this article.

Oil composition - viscosity index. Gasoline saws are standardly equipped with two-stroke engines, so there are 2-stroke engine oils for them (in no case are not four-stroke, but this later). The product itself contains basic oil and various additives, that is, peculiar solvents that improve not only mixing the oil with fuel (gasoline), but also spray it to the piston zone, which is characterized by the so-called "viscosity index". So, choose oil strictly according to the instructions from the company that made the saw, where this "index" is defined. We advise not to conduct experiments so that the motor "does not die" on the first day.

Why can not be used four-stroke oil? It's all about the work principle. The operating cycle of the two-stroke engine, as already visible by the name, consists of 2 times, so its piston is lubricating the fuel mixture without a residue (there is no oil crankcase). The oil in 4-stroke engines does not fall into the combustion chamber and is intended for long-term operation, its composition is calculated on the maximum length of lubricant, and not almost instant combustion, therefore ash is not so important here. After the first use of 4-stroke oil in a 2-stroke motor, and on the pistons, and on the walls of the combustion chamber, the soot, erasing all the surfaces of the cylinders, as a grainy sandpaper.

What are the presence of any additive? The use of certain engine oils in engines depends on the use environment. For example, the boat engine two-stroke most of the time operates at a evenly reduced temperature, which is due to the watering method of cooling, and the motor chainsaws, on the contrary - increased. Therefore, such oils need a metallic type additive that provide effective lubrication with sharp high degrees. However, with a significant decrease in temperature (the operation of the tool at idle), such oils, not beyond the end, isolated a lot of soot, so it should not run the chainsaw, who would not advise you.

We understand with classification and color. Motor oils for 2-stroke engines The manufacturers are painted into one of three colors: green, red or blue. This is done in order to make it convenient to distinguish the usual, undeveloped gasoline and fuel mixture (i.e., the percentage of oil / gasoline, specified in the instructions of almost any branded saw). Each manufacturer of the chainsaw recommends a strict classification for its products: SAE viscosity, by additive quality - ACEA and API. You can delve into details with time, well, and on the first launch it is necessary to buy the oil, which is indicated in the sawpasport saw.

Attention: fakes! It is worth noting that it is not always possible to "run out" on a frank fake, that is, created from anything. Most often, unscrupulous sellers simply flip labels with expensive products on cheap oils. Remember that for most domestic saws do not require super funds at fabulous prices - this is an advertising move, and the sinkers use it. The next "trick" is good eye oil, but without the additives indicated on the package, or there is a additive, but there are very few of them (spilling oil by canister in a dark barn, it is difficult to comply with normal proportions). Therefore, you should not risk - go only in branded shops.
That's basically it. Single Tip: For dosage oil during the creation of the fuel mixture, use medical syringes. At first, it is not worth the masters and pour it "on the eye", since the disadvantage of motor oil is fraught with the "murder" piston. Next, always try to add it to 10-30 grams more than indicated in the instructions for foreign tools, as often domestic products in terms of quality differ from Western counterparts (the instruction has written it for them).
