Chainsaw oil for chainsaws 2 x stroke what

A brief overview of chainsaw chain lubricants

There are a lot of chainsaw chain lubricants on the market today. Let’s look at some popular products.

There is no definite answer to the main question: what chain oil to use for chainsaws? It all depends on the conditions of use of the saw, the frequency of its use and financial capabilities.

Using unsuitable chain oil can cause system malfunctions or even damage to the chain saw. That is why you should immediately exclude waste oil from the list of possible applications.

It is important to respect the proportions of oil and gasoline. With a lack of lubrication, the rubbing parts will begin to wear out, which will eventually lead to the jamming of the tool. If there is too much oil, the engine will start to smoke heavily, which will cause it to get sooty and its performance will decrease.

The correct proportions are given by each manufacturer in the instruction manual. It varies from saw to saw. For example, the oil to gasoline ratio for STIHL, Husqvarna, FUBAG and Champion is usually 1:50 and 1:40 for PARTNER and Makita. Huter recommends to follow the proportions indicated on the oil bottle, the main thing is that it is suitable for air-cooled two-stroke engines.

Reasons for the high demand for brand-name products

STIHL chain saw oil, popular among hobbyists and professional sawyers, is equally suitable for home and professional chainsaws of almost all brands. Husqvarna consumables have identical specifications.

Of domestic developments should be noted the oil Lukoil meets the technical and operational standards. The performance characteristics of this manufacturer’s oil are not inferior to the products of famous brands. Its price is by 150-180 lower than the price of imported analogues.

Specialists advise to follow the factory recommendations, because the use of substandard oils can become a legal basis for withdrawal of the warranty by the service. Filling in the chainsaw cheaper oil surrogate of unknown origin is not safe in terms of reliability and durability of the tool.

What Oil to Fill in your Partner Chainsaw

The quality of the fuel mixture for a chainsaw depends on its uninterrupted operation, component consumption and engine wear.

Ready-to-use mixes are always available in various shops. They already have the right proportions of oil and gasoline for chain saws. These are Partner, STIHL, Husqvarna blends.

However, the latter is not a cheaper counterpart of total purchase of oil and gasoline and making own compositions.

The chainsaw engine is compact because of the two-stroke units. But this design of the internal combustion engine does not technically provide a crankshaft lubricated crankcase, so the oil supply is carried out here together with gasoline, for which the operator pre-mixes them according to the proportions indicated in the instructions. The mixture passes through the carburetor, enriched with air, and thus enters the combustion chamber, where it ignites and simultaneously lubricates the working parts, protecting them from wear and overheating.

Which Oil is Better for STIHL or Husqvarna?

Characteristic features of two-stroke chainsaw power units are high specific power and increased operational requirements to the quality of fuel and lubricants. What oil to use for a chainsaw, so that the tool at low-cost maintenance fully or with a significant reserve will work out the designated resource?

Power units of amateur and professional chainsaws are mainly operated at high operating speeds. Although the advantages of air cooling systems are undeniable, their capabilities are very limited.

Sufficiently comfortable operating conditions of the piston group and connecting rod crank are mainly provided by the characteristics of special engine oils.

Features of the two-stroke engine

Without dwelling on the details of the work of two- and four-stroke engines, it is worth noting one distinctive feature. Parts of a four-stroke engine are lubricated by a separate system. Lubricant is not burned up in the process of operation and serves long enough.

The two-stroke engine is lubricated by a mixture of gasoline and oil, which is burned in every cycle. Such a scheme of lubrication simplifies the structure of the gasoline engine, reduces its weight and with the same working volume increases the power. That’s why two-stroke engines are used extensively in various hand tools, despite being noisier and less economical than four-stroke engines.

In addition, the grease used in two-stroke engines, apply special requirements. It has to burn with as little residue as possible to keep the cylinder contaminated and the exhaust gases with a minimum of environmentally harmful substances.

Oil dosage in Chinese version

Many chainsaws made in China are simplified copies of popular European models. Lack of special materials and proprietary technology contributes to the preservation of the outdated petrol and oil ratio of 25:1.

Double the engine oil consumption is compensated by the lower cost of oil. According to the assurance of the developers, in the composition of Chinese oils the original components are introduced, which help to increase the wear resistance of power units and actually extend their designed service life.

According to independent experts, the best brands of Chinese motor lubricants correspond in quality to mid-priced European counterparts. This is the level of the proprietary motor oils of the Standard and partly Super group.
