What oil to fill in a chainsaw for a chain

Advantages of higher-priced oils

Brand chain oils include useful antioxidant, anticorrosive, stabilizing components and additives that help maintain oil performance and increase wear resistance of working equipment in difficult operating conditions.

The quality of brand name consumables is the benchmark. Mostly from leading manufacturers STIHL, Husqvarna, ECHO, DAEWOO and others. In the past few years have noticeably improved the quality of Chinese chain oils produced by state-owned enterprises.

Owners of chainsaws decide for themselves which oil to use for chainsaw chain lubrication. In the best case, it is adapted to the characteristics of the region consumable material recommended in the instruction manual for this model.

Sorting out the types

When choosing a lubricant, you need to pay attention to these parameters:

  • Base (synthetic, mineral, semi-synthetic).
  • Eco-friendliness.
  • Toxicity of the exhaust.
  • Washing ability.
  • Wear and tear.
  • Ring burn-in.
  • Smoke production.

By the way, if the saw is supposed to be used a lot, it is important that the shaft rotates at a constant frequency. Tool life directly depends on the stability of the shaft the less the frequency varies, the longer the equipment will work.

And synthetic-based greases are specifically designed for machines that operate on an industrial scale.

If you use mineral fluid for a long time, don’t use synthetic fluid. If the equipment has been run in mineral oil for more than 100 hours, a heavy carbon build-up will form in the crankcase. Synthetic oil will break down carbon deposits and their fragments can damage the saw’s cylinder.

Chain saw lubricant is available today from the following popular manufacturers:

The most purchased lubricants are from the German company STIHL. Its three popular varieties:

  • ForestPlus. with increased adhesion, for operation at temperatures up to.15 °C.
  • BioPlus is biodegradable and can be used in cold temperatures up to.15 °C.
  • SynthPlus. allows you to operate your saw in freezing temperatures up to.25 °C.

Useful to know! When solving the problem of what oil for a chainsaw is better suited with several different blends, you should know that the substances of the same type, but different brands are allowed to mix. However, storing such a mixture for a long time is not recommended. Do not mix different types of oil, like synthetic and mineral, even from the same company!

What is the best chain oil for a chainsaw chain: in general terms

Chainsaws are the most widespread in the home and industry. Their specific design makes it necessary to periodically lubricate the chain and many other elements to ensure a long service life. Lack of lubricant can interfere with tool performance, efficiency and durability.

How chain saw oils work

Lubricants for two-stroke engines, despite the popular belief that they are interchangeable for all types of equipment, are quite different.

Conditionally it is possible to make the following gradation: the highest requirements are for boat engine lubricants.

Below. to motor vehicles. The simplest greases are used in chainsaws, chain saws, gasoline generators, and other less loaded machines.

Since two-stroke engines for gasoline-powered saws use a dry crankcase system, the crank mechanism is lubricated by oil vapor in the fuel-air mix, or by a heavy duty engine.

That’s why any 2-titre chainsaw oil must have the following properties:

  • mix well with gasoline and do not precipitate;
  • Have a sufficient volatility for easy mixing with air;
  • reliably protect the main gear parts from wear;
  • do not leave soot on pistons, rings and spark plugs;
  • have environmental properties.

Most of modern lubricants for two-stroke engines in one way or another combine all the above qualities.

Oil Selection Criteria

Many owners of chainsaws, when malfunctions occur, blame the manufacturer of the tool, complaining about cheap components and low-quality assembly. However, the owner’s negligence and desire to save on consumables, in particular oil, often results in breakdowns.

And some people even go to a garage and beg for a liter or two of recycled oil. These savings can translate into relatively high repair costs for the chain saw, new chain and other parts.

Selection criteria for chainsaw chain oil:

  • Viscosity index. This term describes the degree to which the oil’s viscosity changes at different temperatures. An oil with a viscosity index of 90 to 130 is best. The solidification temperature must be at the right value.30 0 Celsius. Viscosity varies according to temperature:
  • Viscosity at 40°C: 100 mm²/s DIN 51562
  • Viscosity at 100°C: 13.5 mm²/s DIN 51562

These criteria are met by oils from well-known manufacturers such as Liqui Moly, Dynamic, STIHL, Husqvarna.

Important things to consider when choosing oil:

  • Versatility. Many chainsaw owners prefer to use general-purpose oils for chain lubrication. This is not a good solution. The temperature difference, when operating in winter and summer, can be as much as 50 0 C. You are unlikely to find a decent mid-priced oil that can reliably protect your chain. Use different types of oil for winter and summer operations;
  • Additives. It is not advised to put regular motor oil in the lube system. The fact is that the manufacturers of lubricants for chainsaws, add special additives to their products, which provide more reliable lubrication of the chain. In fact, oil droplets literally stick to the bar and chain;
  • Thickness. Another reason not to use regular oils. If you notice leaks around the oil tank, you may need to buy a quality chain oil designed to lubricate the chain in your chainsaw;

Important: Many users say that they successfully use mineral gear oils with a viscosity of 15-40 for summer and 10-30 for the cold season. They can be used for a while, but it is necessary to adhere to the temperature conditions and to keep the oil pipeline clean.

Selection criteria for self-selection

The question of how to replace brand name chain oil that is not available on the market is a hot topic in many peripheral regions. According to experts, the products of the well-known brands STIHL and Husqvarna are identical by their main characteristics and are a full-fledged analogue. Motor and chain oils from these manufacturers have proven to be the best in every respect.

Given the possibilities of the offered range, the consumer can make a choice in favor of a more expensive chain oil or its budget counterpart. In addition to the brand-name products, the list includes Enkor, Nanotek Standard and Nanotek Premium oils that maintain their performance at temperatures up to.30°С.

Mineral-based versions are represented by Makita and Makita Oregon brands, organic chain oils Makita Biotop, STIHL Bio Plus have identical lubricating properties and are sold in packages of 1 to 25 liters.

Professional sawyers mostly prefer brand name lubricants of the same brand. Using the same brand of oil all the time allows you to learn its capabilities and use them to the best of your ability.

Overview of the chainsaw chain lubrication system

To understand how important choosing chain oil for a chainsaw is, let’s take a look at how the lubricator itself works, using the STIHL 180 as an example. This model has been chosen as one of the most popular models of STIHL chain saws.

The chain lubrication system of the STIHL chain saw 180 consists of several main parts:

  • Oil expansion tank;
  • the lubricant supply tubes from the reservoir to the pump;
  • The oil pump;
  • the lubricant supply ducts to the bar (on some saws the intensity of oil injection into the bar can be adjusted);
  • duct systems inside the bar to distribute the lubricant over the whole working surface of the bar.

The chain lubrication intensity for the STIHL 180 chain saw is not normally regulated manually. You can adjust the oil flow to the chainsaw chain in some other models (for example, on Husqvarna saws).

Oil is poured into a reservoir for each refueling. The chain saw has been designed in a way that a small quantity of oil should still be left in the oil conservator after the fuel has been used. That means that, if properly operated, there is no chance of the chainsaw running dry.

The lubrication system works as follows. The crankshaft drives a simple designed rotary oil pump by means of a kinematic connection.

An oil pump creates suction and draws lubricant from the reservoir. It then injects it under pressure into the tire duct system. Oil is applied to the chain sprockets and dispersed over the entire chain. The chain, the bar’s running surface and its front needle bearing are lubricated.

Filling a STIHL chainsaw with fuel and chain oil

In order to understand what role lubricants play, it is necessary to have a general idea of the machine’s operating scheme. Although in the store when buying usually say a couple of words about what and how it is set up, and in what throat to fill what not unreasonable to update simple information on the subject.

Engine oil

All chainsaws, just like their fellow brushcutters and cultivators, are equipped with two-stroke engines. They develop a high power density for small dimensions. Due to the duty cycle in two strokes, the speed of such engines also exceeds all the usual car engines. On the other hand there is a heavy load on the assemblies and details, air cooling, which also requires a large safety margin. To reduce the wear and tear of the elements is possible only through the use of quality lubricants.

The peculiarity of two-stroke motors is the absence of an oil pan and a pump that would deliver liquid lubricant to all rubbing and interacting parts. The advantage of this scheme is the constructive simplicity, less number of units in the engine. On the other hand, there is a question of how to deliver lubricant to the critical areas, the most demanding of which is the cylinder and piston.

The solution was to add oil to the fuel. Gasoline is not put in the chainsaw‘s tank in its pure form, but mixed with a certain quantity of lubricant. Before it enters the combustion chamber, the mixture washes the necessary parts and then exits the exhaust manifold in the form of exhaust fumes.

Chain oil

It also needs oil in order to work properly and for a long time. Without it, the metal will very quickly begin to overheat, and then will cease to perform its functions at all. in addition, the oil in the chain makes it run easier when pulling the chain through solid wood. Reducing drag not only prolongs chain life, but also relieves engine power and reduces fuel consumption. The characteristics of chain oil are fundamentally different from those of oil mixed with gasoline.
