What kind of gasoline a STIHL chain saw works on

How to replace expensive oil

The disadvantage of special brand-name chain lubricants is their high price. Buying a liter of other expensive oil is easy. And if you are going to work that requires several liters or even dozens of liters, you will surely think of saving. The main thing here is not to go to extremes. You can save money on oil to the extent that you will have to change the chain several times or even the tire itself or the oil pump.

There are three options for replacement. First of all, you can use specialized products of little-known manufacturers for chain lubrication. But such oils are still to be found. And there’s a risk of coming across a low-quality product.

The use of automotive engine oils. As a temporary substitute they can be used, but they can not boast of high adhesion, so the quality of their work will be obviously worse than special oils. For this reason it is not recommended to use heather and diesel oils. they have the worst adhesion characteristics.

And it is necessary to mention one more option. refuse. This is the name given to the oil that has reached the end of its service life in an engine and is drained when the engine is replaced.

In fact, it’s not an option at all. There are bound to be metal particles in the waste oil. And while it might not harm the chain itself, it certainly would not harm the oil pump or the entire lubrication system. On the Internet forums, you can find a “killing” argument in favor of used oil. that the Soviet Druzhba chain saw had no chain lubrication at all and worked. So you can use whatever you want. Well, the STIHL will work with used oil, or even non-lubricated chains. The question is how long it will run and how many chains will need to be replaced in that time.

Caution for chainsaws that are under warranty. Foreman in warranty shops know how to spot cases of low-quality chain lubrication. Especially when using low-quality waste. Denial of warranty repair is effective immediately.

Which chainsaw parts need oil?

The quality of the grease determines the engine’s service life. Despite the low displacement, chainsaw engines are relatively hardwearing. Inertial loads on the crank mechanism components are proportional to the square of the rotation. Since most gasoline-powered tools most often work at “full throttle”, chainsaw oil must retain its properties at high shear rates, not allow dry friction in the crankshaft bearings and piston group.

Besides the engine, the bar also needs to be lubricated: the sliding chain inevitably wears it out. Forced-air oil supply from a separate tank conserves life of both bar and chain. If possible, the oil used for lubrication should be as sticky and viscous as possible so that it adheres better to the chain and guide bar and does not fly off. In addition, according to the requirements of ecologists such oils are usually biodegradable.

STIHL chain saw. what kind of gasoline

Chainsaw service life and performance depends on the quality of your gasoline. Many people disregard this and consider it a secondary issue and put whatever they can find in the chain saw: 92, 95, 98 and even dirt and expired oil! The bottom line is that such fuels cause the tool to malfunction and need to be repaired. Let’s take a look at how important it is to use the right gasoline for your chain saw!

How much fuel to store?

During prolonged storage, gasoline evaporates (regardless of brand), precipitates at the bottom, it loses its properties, in other words. deteriorates. It is worth knowing that it is not so much the gasoline itself that catches fire, but its vapors. So if you have a can of gasoline in the garage from last year, then think about whether it’s worth it? Better leave it to light a barbecue fire.

Using “stale” gasoline for a chainsaw entails a lot of problems:

It is worth remembering that the prepared fuel mixture (gasoline with oil) is stored for no more than a month, after this time it should be disposed of.

Using an old mixture increases wear and tear on the chain saw’s engine. don’t forget about it! All of this will soon lead to a costly repair of the chainsaw, at best the carburetor, at worst the engine.

Chapter 7: Fueling Your STIHL Chainsaw

What octane number to use. 92, 95 or 98??

Here’s where the fun part comes in. Can I fuel my chainsaw with 95 mln?? In all chainsaw instruction manuals, manufacturers specify in bold: “Do not use gasoline with an octane rating higher than 92 to prepare the fuel mixture. It is understandable, but probably not for everyone.к. chainsaws with a burned-out cylinder are brought in to service centers time after time!

Let’s understand what kind of gasoline is good to put in a chainsaw, and what kind is not! For all two-stroke chainsaw engines you should use 92 gasoline, that’s what the tool is designed for.

When pouring 95 gasoline, detonation (pushing the piston to the opposite direction) will start in the engine, something like a micro shock, which will happen almost at every crankshaft revolution. About 98 gasoline I think everything is clear, the effect will be even stronger, and it will be a mini shock.

For your reference! Did you know that the fuel should not always be prepared in a ratio of 1:50? It turns out that the ratio can be 1:40 and even 1:25. What it depends and when to choose the right ratio, read our detailed article-guide about the proportions of oil and gasoline for chain saws of all brands.

Why don’t you use dirty gasoline??

Some owners of chainsaws believe that if the tool works in constant dust (in the carburetor even has an air compensator in case of a clogged air filter), then it means that it is able and gasoline with pieces of rust to swallow and the chain lubrication waste with small pieces of metal will go, so?

It’s another common misconception, never use gasoline from the bottom of a canister (much less rusty). The chainsaw has a carburetor, which has shallow channels that can get clogged by these small particles, which in turn will cause the chainsaw to break down and call a specialized repair shop.

If you have no way out, urgently need gasoline, and have only a “rusty canister of liquid” at hand, make a filter from a very fine mesh, such as gauze, and filter it before refueling.

Also recommended to read an interesting article about what oil to use for the saw engine and chain (here you will find many arguments why you should not use used oil).

In order that the chainsaw served for many years, never fill it with old gasoline, and it is not necessary to use the brand 95 and the more so 98 gasoline to prepare the fuel mixture, only 92. Also, do not forget about the purity of the gasoline. no odenko!

STIHL chain saw MS 250. features and specifications

Every STIHL model is powered by a single-cylinder two-stroke petrol engine with a fuel mix of at least 92-grade AI-92 gasoline and motor oil.

STIHL MS180 chain saw A couple of things to know about what really gets into a chain saw. Always keep an eye on.

The main thing is to correctly calculate the proportions of the mixture. Excessive oil can burn pistons and spark plugs. Excessive gasoline can cause engine damage or galling of the pistons. Each manufacturer gives its proportions to the models of different power.

To mix the components, you will need the aforementioned additional accessories. Also on sale you can find special canisters with two holes for oil and gasoline. Here everything is very simple, pour the ingredients, close the lid tightly and mix by tilting the container. You can use glass and plastic bottles.

No water or dust should enter the fuel mixture.

How much gasoline is stored

During long-term storage, gasoline evaporates (regardless of brand), the sediment falls out at the bottom, it loses its properties, in other words. deteriorates. It is worth knowing that it is not so much the gasoline itself that catches fire, but its fumes. Therefore, if there is a can of gasoline in the garage from last year, consider whether it is worth it? It is better to leave it to light a barbecue fire.

What kind of gasoline to fill a chainsaw?

Hello! Good to see you again, dear readers and subscribers of Andrey Noak’s Blog. Everyone who has a chainsaw at home already knows exactly what gasoline and how to fill it up. But to the one who only wants to buy a machine, the article will seem entertaining.

The chainsaw is one of the most convenient and versatile household units. Before using it, you need to prepare the fuel mixture. But for the machine to work properly, you need to follow all the manufacturer’s recommendations. Every model is different, so what kind of gas to put in a chainsaw?

Oil Purpose

Since the two-stroke engine is not equipped with a lubrication system, it is necessary to fill the chainsaw with a pre-prepared mixture of gasoline with special oil. The domestic models often use M8, M12, MGD-14M grades. Well-known foreign tool manufacturers insist on the use of oils of their own brand, which are developed in cooperation with the leaders of the oil refining industry. But practice shows that replacing one quality oil for two-stroke engines with another does not negatively affect the characteristics and duration of operation of the equipment.

According to the production method of the motor oil base they are divided into:

kind, gasoline, stihl, chain

In this list they are listed in ascending order of quality and price. So if you add synthetic STIHL chainsaw oil to your Husqvarna chain saw it won’t know the difference.

How to choose chain saw oil

The main indicator of quality, which can be evaluated independently, is the combustion smokiness. Modern standards for two-stroke oils directly set the limits. That’s why high-quality oil with a normal fuel mixture should emit as little smoke as possible.

Unlike automotive lubricants where the main standards are set by API (American Petroleum Institute), two-stroke oils are mainly based on their own quality classes. The JASO F system developed in Japan is now the most widely used. The largest proportion of two-stroke engine lubricants correspond to JASO FC and FD. It was the JASO FC grade that once introduced the concept of “low-smoke oil. That is, the oil for chainsaw lubrication should correspond at least to this class, not only to protect the engine from wear and tear, but also to make the work more comfortable.
