What oil to mix with gasoline for a chainsaw

Main brands of chainsaw motor oils

Stihl and Husqvarna are leaders in the production of quality lubricants for chainsaws and lawn mowers. Their range includes both conventional mineral lubricants for two-stroke engines and synthetic heavy-duty oils. Let’s consider the assortment in more detail.

HP Ultra

Another oil from Stihl. Has a synthetic base, due to which it has improved combustion characteristics, cleanliness and engine protection.

Recommended by the manufacturer for long-term use in harsh conditions. Ideal for low temperature applications. HP Ultra is environmentally friendly as spilled oil decomposes 80% in just 21 days.

It is packed in two types of containers, 100 ml and liter bottles. The proportion of the finished fuel mixture is 1:50, which means that a 100 millimeter bottle is enough to prepare 5 liters of the mixture. Green colour. Shelf life 4 years.

The cost of this oil is significantly higher than the cost of STIHL HP, therefore it is not profitable to use it constantly.

It is worth noting that Stihl oils, before they go on sale, go through the company’s laboratory, where they are tested for compliance with all the requirements..

gasoline, chainsaw

When developing oils, much attention is paid to fuel combustion, starting characteristics during cold start, biodegradability, viscosity change at different temperatures (information from the official website of the company).

Choosing the right chainsaw oil

Almost all modern chainsaws and lawn mowers are equipped with two-stroke engines. Their lubrication is due to the oil that is added to gasoline, there is no oil sump and pump in them.

In order to extend the life of the engine, it is necessary to use special lubricants, which will be discussed in this article..

STIHL HP mineral grease has been specially developed by STIHL engineers for use in their tools. That is why owners of chainsaws and Stihl lawn mowers are recommended to use this type of oil..

Its color is red, the shelf life in a closed container is no more than four years. It is packed in several types of containers, so you can choose the most convenient packaging for yourself. Not so long ago, a convenient container of 20 grams appeared, which is diluted by one liter of gasoline. For those who rarely use a chainsaw, this is the best option. Can be thinned and consumed immediately.

Important: it is not recommended to store the ready-made fuel mixture for more than one month, since it gradually oxidizes and the lubricating properties are lost..

STIHL HP fully complies with high European standards.

Husqvarna HP 2-stroke

Husqvarna HP, like its STIHL HP counterpart, is also specially designed for 2-stroke engines..

According to the manufacturer, this type of oil has additives that compensate for the low quality of the fuel, which is important for our country. The declared octane number of gasoline at filling stations rarely corresponds to the real.

Husqvarna HP – semi-synthetic, green. It is packed in a liter or ten-liter container. The proportion of the mixture is 1: 50, i.e. 20 grams per liter. During the running-in period of the saw engine or when working in cold weather, it is allowed to increase the proportion to 1:40, which will give the engine more protection and increase its service life.

Today, there are a large number of two-stroke engine lubricants on the market from different manufacturers. For this reason, it is rather difficult to answer the question of which chainsaw oil is better. In our opinion, you should trust reliable companies, which are Stihl, Husqvarna, Oregon, Champion. It is their oils that will maximize the protection of the engine of your tool and extend its resource..

Unscrupulous manufacturers often disguise their products under well-known brands (Husqvarna, Stihl, etc.). Such oils are of poor quality and can damage the engine. In order not to be deceived, it is necessary to purchase lubricants from official representatives who have the necessary certificates for the products. How to distinguish a fake from an original can be found in

What oil to use for a chainsaw engine

To lubricate the internal parts of a chainsaw engine, special oils must be used that differ from lubrication for four-stroke engines in several ways..

  • The first is the quality of cleaning. Chainsaw engine oil should be as cleaned as possible from various impurities. This is due to the fact that the channels in the carburetor of the chainsaw are too small and if the fuel mixture has any impurities, they will clog up, and accordingly the engine will stop working..
  • Second, it is low smoke when burning. As you know, saw oil must be mixed with gasoline, which subsequently burns out in the engine cylinder, and, accordingly, the lubricant burns with it. If a large amount of smoke is emitted from the burning mixture, this will negatively affect the exhaust system and, alternatively, the health of the operator..
  • Third, chainsaw lubricant should burn with minimal carbon deposits. Low-quality oils, when burning, form a large amount of carbon deposits, which coke the piston and the exhaust system.

The consequences of using low-quality oil can be very sad, to the point that it will be necessary to replace the piston group of the chainsaw. Coking of the exhaust system entails a decrease in engine power, since the throughput of the muffler and the exhaust window of the cylinder decreases, up to their complete clogging. Carbon deposits under the piston rings will not allow them to shrink, which will lead to the formation of scoring on the cylinder walls and engine seizure.

Important: it is strictly forbidden to use diesel oil for a chainsaw, since it is not suitable for all of the above parameters..

Using special lubricants for two-stroke engines is not only beneficial for the engine, but also convenient, since manufacturers add dyes to them, thanks to which it is possible to determine whether gasoline is diluted or not, which is impossible in the case of conventional engine oils. Four-stroke engine oil mixed with gasoline is colorless.

The mixing ratio for a two-stroke engine is indicated on the packaging. Manufacturers recommend adhering to the dosage, since the use of the wrong mixture of oil and gasoline also affects the life of the engine, and it is harmful to both increase and decrease the proportion.

Tip: a guarantee of the performance of the chainsaw engine is the use of high-quality oil in the correct proportion.

How lubricant quality affects engine life

Now let’s talk about how specifically the quality of the oil affects the operation of the engine and its resource, since many do not understand this.

The principle of operation of a two-stroke engine implies that the lubrication of its internal parts is due to the oil in the gasoline. It lubricates the crankshaft and connecting rod bearings. Also, the oil envelops the cylinder walls and reduces the friction of the piston rings..

The engine of the chainsaw is highly revving, some models can develop up to 15,000 rpm, which puts a tremendous load on the bearings and other engine parts. Insufficient or poor quality lubricant will cause the bearings and piston to run virtually dry, resulting in increased temperatures. Elevated bearing temperatures can cause bearing seizure..

Heating the piston to the limit causes it to melt, particles of aluminum from the piston are transferred to the surface of the cylinder and, cooling slightly, become solid. Rings, passing the area with aluminum build-up, get damaged or wedge.

Another danger of poor-quality lubrication is carbon deposits. Carbon deposits can form under the piston rings, making it difficult or completely stopping their proper operation, and in the exhaust port. It is not uncommon for carbon deposits to completely seal the exhaust window and muffler. Below is a video about the consequences of using low-quality oil..

The ratio of gasoline to chainsaw oil

Household and professional chainsaws are powered by two-stroke internal combustion engines running on a metered mixture of gasoline and engine oil adapted to the difficult operating conditions. The correct proportions of oil and gasoline for a chainsaw is one of the important conditions for stable traction characteristics of the engine and low-cost development of its assigned resource..

The need to obtain a sufficiently high power from a small-cube power unit makes it necessary to operate chainsaw engines at high-speed modes, therefore, increased requirements are imposed on the quality of both components of the fuel mixture..

Which brand to use motor oil?

For each model, the manufacturer advises a list of materials to be used. It is better for the user to adhere to these recommendations, because the warranty does not cover tool breakage due to inappropriate fuel and lubricant. In this case, the owner himself pays for the repair of the chainsaw, which can be up to 80% of its cost. When you can’t follow the manufacturer’s recommendations, try to follow these rules:

  • Use oil only for 2-stroke engines.
  • Do not use after expiration date.
  • Do not add used oil with a large amount of impurity to gasoline, as the mechanisms of the tool can be damaged.
  • Chain lubricant cannot be used for the fuel mixture.
  • It is preferable to use synthetic and semi-synthetic oils, which are more expensive than mineral oils, but do not form harmful deposits..

Why you need to mix oil and gasoline

When using the saw, gasoline should always be mixed with oil. The reason for this is the design features of a two-stroke internal combustion engine. It does not have a dedicated lubrication system for parts (as in other internal combustion engines) and, accordingly, its cylinders with O-rings, crankshaft, bearings and connecting rods must be lubricated directly in the process of obtaining fuel.

How to refuel the saw

A plastic bottle is best for refueling your chainsaw. The volume of the container should be equal to two liters if you will use the tool frequently. A smaller container should be used when you rarely use the saw..

Dilute fuel and lubricant in a separate bottle. It is necessary to observe the exact proportions, which are indicated in the instructions. It is recommended to leave an empty space in order for the liquid to mix well..

Such a mixture should be stored no more than two weeks. Be sure to shake the bottle before use. Experts do not recommend diluting a large amount of the mixture at once and storing it for years. The storage temperature should not exceed twenty-five degrees Celsius. If more, then the shelf life is reduced..

Refueling your chainsaw with oil

Long-term storage of the mixture greatly impairs the traction capabilities of the engine. Carbon deposits form, the ability of the pistons to move quickly is reduced.

Choosing engine oil

An oil intended for a 2-stroke engine must meet the following requirements.

  • The lubricant should form a minimum of ash during combustion. Ideally, it should burn completely.
  • The lubricant must have good solubility in gasoline and a high degree of purification from various impurities that can cause clogging of very narrow channels of the carburetor.
  • The oil must have high anti-corrosion, anti-wear and lubricating properties..

There are certain standards for oils intended for 2-stroke engines: TC-W3 and 2T. A grease complying with the TC-W3 standard is used for water-cooled engines (outboard motors, jet skis). 2T oil is used as an additive in gasoline for 2-stroke air-cooled engines (lawn mowers, mopeds, chainsaws, etc.).

MOTUL Outboard Tech 2T Oil

Oils can be green, red or blue in color. This is done so that their presence in gasoline can be easily determined..

When using poor-quality lubricant, the entire piston group of the engine can fail due to the formation of carbon deposits under the piston rings. As a result, they will not be able to compress, and scuffs will form on the cylinder walls. Also, improper lubrication of the bearings of the crank mechanism leads to overheating and, ultimately, to seizure. Important: it is forbidden to use diesel oil to prepare the fuel mixture, since it does not correspond to any of the above parameters..

Fuel mixture working proportions

The standard gasoline to oil mixture ratio for carburetor chainsaw engines of various models is 40: 1 and 50: 1. This proportion provides full lubrication of the rubbing parts of the crank mechanism and piston group, and also does not prevent the complete combustion of the gasoline-air mixture..

Taking into account external factors, the fuel mixture can be adjusted to increase the amount of oil. Such a need arises at the stage of running in a new tool, as well as at high air temperatures. In this case, the standard oil dosage is increased by 20%..

In practice, an increase in the percentage of oil in the fuel mixture is used if its characteristics do not fully meet the stated requirements. How much oil per liter of gasoline is needed in each case is determined by the sawman himself.

Features of running in a new tool

This concept includes the gentle operation of the chainsaw at the initial stage of its operation. The technology also provides for the operation of the engine on a mixture with an engine oil increased by 20%.

The running-in time in engine hours is indicated in the attached instructions. In practice, for the tool to reach the working level, it is enough to generate 3-5 refills of the saw’s gas tank.

New models do not need running-in, but the first hours of operation are not recommended for the chainsaw to be used with heavy loads..

How to mix oil with gasoline

Engine oils are used to add to trimmer gasoline. Mixing is done in a certain proportion. Manufacturers have different volume ratios: from 1 to 50 to 1 to 20. The technical specifications refer to this. You have to be careful with a small amount of oil. A small inaccuracy leads to oil starvation of the engine, reduces its resource.

There are products in which the proportion is indicated from 1 to 20-40. It is best not to use such a lubricant. The wide range of mixtures indicates the poor quality of the product. The appearance of piston rings with constant use of these grades is almost guaranteed..

M-8 engine oils are added in a 1-20 ratio. In high-speed motors, their use is undesirable. The cycle between supplying the mixture is so small that it will cause an overabundance of lubricant in the cylinder. Trimmers are slow speed so they allow the use of low grade grease. Due to the initial low resource, there is no need to worry about the cuff of the rings. Before there is a complete deterioration in the quality of the equipment.

It is not a principal to use the recommended oil or other manufacturers. The main thing. dilute the gasoline with trimmer oil in the proportions according to the product specifications. Refusal from service workshops, which should only be guaranteed based on the use of a different brand of grease, but with acceptable parameters, is illegal.

What oil to mix with gasoline for a trimmer

Why trimmer oil mixes with gasoline

The two-stroke engine has a simple yet extremely efficient design:

  • The piston performs a working stroke every second cycle;
  • the cylinder is lubricated with oil dissolved in gasoline;
  • removal of combustion products occurs due to compression, without a special mechanism.

All this led to the creation of a family of small engines, successfully adapted to domestic and professional equipment:

  • trimmers;
  • chainsaws;
  • motorcycles;
  • various tillers.

Due to the design features, it was possible to achieve the desired fuel consumption only on small engines with a power in the range of 15-20 liters. It’s especially good that this figure looks in the 1 to 5 hp range. Here, the low weight and dimensions of the engine fully correspond to the consumption of gasoline..

As the size increases, the area of ​​the inlet and outlet ports increases. The process of gas removal and fuel supply deteriorates dramatically. In this regard, it was necessary to move to a more efficient system for burning a mixture of gasoline, which would include the presence of forced engine maintenance systems. The four-cylinder models have taken over the palm of the big power plant. Combining them into multi-cylinder designs made it possible to create special systems associated with the formation of the composition of the fuel mixture, lubricants, etc., which had a beneficial effect on gasoline consumption..

The rubbing elements of the piston and cylinder of a two-stroke engine are lubricated with oil, which is in a certain proportion in the fuel composition. Gasoline burns out, and oil settles on the surface of the cylinder, reducing the friction of the rubbing parts. Why do you need lawn mower oil. You can mix gasoline with lawn mower oil like water. Lack of lubrication leads to cylinder damage, up to and including seizure. The main thing is to dilute gasoline with trimmer oil in accordance with the proportions in accordance with the product line. In case of excess, under the influence of high temperatures, the thermally modified product is deposited in the annular grooves. You can mix gasoline with lawn mower oil as the engines are of the same brand. Compression drops, and with it power.

Ratios of gasoline and oil for the Stihl trimmer

Stihl, a German manufacturer of high-quality cutting tools, produces motor mowers in addition to chainsaws. It is an indispensable tool for mowing grass and lawn trimming with ease and mobility..

a lawn mower, or trimmer, also has a two-stroke engine and is fueled with a fuel mixture. For the Stihl trimmer, a ratio of 1:50 is recommended (for 5 liters of gasoline, 100 ml of oil).

Gasoline selection

The first question that the user faces before starting work is what gasoline to pour into the Stihl chainsaw.

Gasoline for the Stihl chainsaw is filled exclusively with unleaded high-octane gasoline, that is, with an octane number higher than 90. If you fill it with a low-octane gasoline, it is fraught with engine overheating, piston seizure and engine failure. Therefore, it is optimal to pour AI-92 or AI-95 gasoline into the chainsaw, but here the question of fuel quality arises.

Poor-quality AI-92 may “fall short” of the declared octane number, and AI-95 often contains many additives that do not bring any benefit to the engine. In addition, if the additives are of poor quality, they do not last long, and after a few days the purchased fuel can turn into a low-octane fuel, which is not suitable for a chainsaw engine..

How to mix your own fuel for STIHL chainsaws & equipment

At the same time, a good 95 can harm the piston system – “burn” it. Thus, some users found a way out: to refuel the chainsaw with AI-92 gasoline mixed with AI-95. This achieves an optimal balance between octane number and the amount of additives..

What gasoline and oil is better to choose for refueling a Stihl chainsaw: a table of ratios, how to breed, proportions

The durability and reliability of a chainsaw is determined not only by the conditions of its operation, but also by the quality of the fuel used for refueling. In addition to the special conditions of use, when grinding parts in the first few refuelings, attention must also be paid to the quality of the fuel mixture..

Professional Stihl chainsaws are equipped with two-stroke engines that require high-quality fuel – a metered mixture of high-octane gasoline and oil, designed to operate the engine at high speeds. The correct choice of gasoline and oil for the Stihl chainsaw is the key to a long and successful operation of this unit..

How to breed

Stihl saws fuel mixture is prepared by mixing high-octane gasoline and two-stroke engine oil. The proportion of oil and gasoline for a chainsaw is as follows: if the power of the unit does not exceed 1.5 kW, then the ratio will be 1:40 (i.e. 25 ml of oil per liter of gasoline), and if the power is higher than this value – 1:50 (20 ml for 1 l).

Looking at the table of proportions, we will analyze, using the example of two saws of different power, how to mix oil gasoline.

  • For the low-powered STIHL MS 180 with a 2-stroke engine, the dilution will be 1:40. The volume of the fuel tank is only 0.25 liters. In order to mix fuel with oil for one filling, we need 6.25 ml of oil for 0.25 liters of gasoline.
  • For the STIHL MS 660 heavy-duty professional chainsaw, dilute oil and gasoline in a ratio of 1:50. This model has a fuel tank capacity of 0.825 l. In order to understand how much oil to pour for such a volume of gasoline, we multiply 0.825 by 20. It turns out that 16.5 ml of engine oil is required.

Correct Way To Mix Gas and Oil For a ChainSaw, WeedEater etc – Video

In practice, of course, it is not necessary to calculate what proportion of the lubricant will be diluted in the volume of gasoline per filling. Usually, the fuel mixture is diluted in a volume of 1-2 liters, which is enough for several refuelings of the chain saw.

You need to dilute gasoline for the Stihl chainsaw in a separate canister, in no case pouring the components into the saw’s gas tank separately. These engines do not have an oil pump and the possibility of installing it, so only ready-made fuel is poured into the tank. There are even special canisters with two necks on sale to make it easier to dilute the mixture, but you can add oil to gasoline for a chainsaw and in an ordinary canister.

It is better to observe the proportions of refueling the chainsaw as accurately as possible: excess oil will create carbon deposits on the spark plugs and pistons and provoke detonation during fuel combustion. This can shorten the engine life. In addition, the user of the saw in this case is forced to inhale the exhaust gases with unburned fractions. At the same time, excess gasoline can damage pistons due to insufficient lubrication..

Some folk craftsmen, in the absence of special measuring accessories, advise using a plastic bottle: a full cap (from the same bottle) of oil is poured into a half-liter container filled with gasoline. The output is an approximate ratio of 1:50.

It is better to calculate the amount of mixture for refueling in advance based on the expected volume of work and the declared consumption of this engine. The volume of the tank in most chainsaws is about 0.5 liters, a 2 kW engine will consume approximately 1.2 liters per hour of operation (for more precise characteristics of the saw, see the instructions). Thus, it makes no sense to prepare a mixture in volumes exceeding 3 fillings in a row..

Before starting the preparation of the mixture, it is recommended to thoroughly clean and dry the neck of the canister and the area around it in order to avoid the ingress of impurities: dust, water, etc. The same is done with the tank before filling the fuel: the lid and neck are cleaned of dust and adhering dirt, so that it does not get into the gas tank, and then into the engine.

Oil selection

Unlike four-stroke engines, Stihl 180 chainsaw oil is poured directly into the gas tank, after being mixed with gasoline. It is recommended to fill the chainsaw with the oil specified in the instructions for this model..

Under no circumstances should you use oil intended for low-speed engines (boats, scooters, etc.).

It can significantly reduce the life of the engine, and if traces of such a substance in the cylinder-piston group are found, the tool will be considered withdrawn from the warranty, that is, it will not be subject to warranty repair or exchange.

Stihl synthetic and mineral oils for chainsaws are sold in bottles or cans of different capacities: from 100 ml to 5 liters. Mineral ones have a lower cost, while semi-synthetic and synthetic ones ensure complete combustion during engine operation, i.e. no carbon deposits and a minimum of toxic compounds in the exhaust.

In addition, synthetic oils retain their properties over a much wider temperature range, and also contain special additives that are useful for engine operation: antioxidant, detergent, preservative, etc..

You can choose an engine oil for your tasks depending on the saw model and the frequency of its use: the oil consumption during the operation of the device is low, and given the shelf life of semi-synthetic and mineral lubricants, there is a risk of simply not having time to use even a liter bottle to the end..

So with a small estimated amount of work, you can not buy a bulk canister, but limit yourself to a bottle. Only Stihl mineral greases do not have an expiration date.

Stihl oil

Stihl produces its own oil for its tools. High quality Stihl 2-stroke oil with high lubricity.

Consider the table of the assortment of oils for chainsaws from the official site of Stihl.

Here we see two types of motor oils:

  • HP
  • mineral base,
  • has a shelf life of 4 years,
  • minimum application temperature: -10 ° C
  • available in volumes from 20 ml to 55 l.
  • HPUltra
  • synthetic,
  • has a shelf life of 4 years,
  • burns out completely in the piston group,
  • biologically safe and degrades more than 80% in 21 days,
  • low smoke,
  • minimum application temperature: .25 ° C
  • available in 100 ml and 1 l volumes.

The manufacturer also suggests in the description for lubricants how to dilute the mixture for refueling the saw – in a ratio of 1:50.

Useful Tips

When calculating the proportions, remember that it is better to pour oil a little than to save on it: only a significant excess of lubricant is dangerous with the formation of carbon deposits, and a slight excess will not harm the engine. If you do not fill it, the consequences can be more dangerous..

When mixing fuel for a Stihl chainsaw, the manufacturer recommends that you first pour oil into the canister, then add gasoline and then vigorously mix the components. But the practice of use shows that the oil can “stick” to the walls of the canister and mix poorly, so it is better to carefully pour the oil into the gasoline and mix.

It is better not to leave the remains of the fuel mixture in the tank in order to prolong the life of the rubber seals and other parts susceptible to chemical damage. After stopping the saw, the fuel must be drained and disposed of: during long storage (more than a month), the octane number and other physicochemical properties of the mixture decrease and it becomes unsuitable for safe use.

In addition, after emptying the gas tank, you need to start the saw engine and let it run at idle speed until it stops on its own – this will mean that the carburetor is also rid of the remaining fuel mixture..

It is important to remember that the long-term performance of the equipment is largely dependent on the user. Saving on fuel in the case of a chainsaw can be much more expensive in the future – by out-of-warranty repairs of a broken saw or by purchasing a new unit. Compliance with the manufacturer’s instructions in most cases helps to understand the principles of the device and prolong its trouble-free and trouble-free operation..

Chainsaw oil

Hello everyone! In this article, I will tell you which chainsaw oil to use. The information presented here is based both on my personal experience of using saws, and on the experience associated with the fact that I am a sales consultant for this technique – this is both communication with buyers and with service masters. Plus there will be a theory – where can we go without it?.

What kind of oil to pour into gasoline for a chainsaw?

To prepare the fuel mixture, a special oil for two-stroke engines is used. There are a great many of them today. However, manufacturers themselves, especially serious ones such as Stihl or Husqvarna, always write which oil to mix with gasoline for their chainsaws. They are produced under the same brand, so, for example, Stihl oil is suitable for Stihl saw, and Husqvarna oil for Husqvarna..

At the same time, representatives of manufacturers declare that they do not know how the chainsaw will work with other oils, but they can definitely guarantee the correct operation of their equipment when the fuel mixture is prepared for it based on the product that they indicate in the operating instructions. By the way, if a malfunction occurs in the piston group during the warranty period, you may be denied a free repair if it turns out that you added something other than what the manufacturer indicates.

The masters from the services with whom I had to communicate praise all the same Stihl and Husqvarna oils.

Mineral or synthetic oil – which one is better to add to gasoline

Two-stroke oils can be mineral or synthetic. As in the case of a car, synthetics are always more expensive here than mineral water. Its most important advantage is that no carbon deposits form inside the chainsaw cylinder when used. This extends its service life. Thus, if you want the saw to last as long as possible, fill in synthetics.

True, it is worth noting that if you have already used mineral water for a long time (at least 100 hours), then you cannot use synthetics. This is due to the fact that synthetic oil, having cleaning properties, will wash away the carbon layer accumulated on them from the cylinder walls, and its fallen off pieces can lead to damage. Therefore, if you have been using mineral water for a long time, then use it..

Chainsaw Oil to Gasoline Ratio

To find out how much oil to pour into gasoline for a chainsaw (as for any other two-stroke technique: trimmer, motor-drill, etc.), you need to look at the correct proportion in the instructions for the saw or on the packaging. Usually, when using the “native” version, the proportion is 1:50. If a different type is used, it is recommended to mix it in a ratio of 1:40. That is, for example, with a ratio of 1:50, we divide 1 liter by 50 and we get 0.02 liters – this is the amount that needs to be added to 1 liter of gasoline. That is, for 1 liter of gasoline, pour 20 ml.

The proportions of gasoline and chainsaw oil must be observed with great accuracy, therefore, to determine the required amount, I advise you to use a conventional medical syringe of 20-25 ml. In addition, there are special packages with a dispenser, as well as containers for mixing. The latter allow you to measure as the required amount of both mixed products..

When using a syringe or a package with a dispenser, you need to have a container for which you can accurately measure the required amount of gasoline.

So, after adding the required amount of oil to gasoline, just shake the container in which they are mixed, and that’s it – the fuel mixture is ready.

You should not stock up on the mixture for future use, as it has a limited shelf life. Usually, the shelf life after mixing should not exceed one month, but some service centers recommend generally storing the finished fuel mixture for no more than 3 days.

What oil to use to lubricate the chainsaw chain

Now let’s move on to chain lubrication. To lubricate the chain, you must use special adhesive lubricants specifically designed for this. You can, of course, fill in other types of oils, for example, transmission or engine oils, but they will not lubricate the bar and chain as effectively as a special adhesive oil for lubricating the chain does..

This is due to the fact that the special lubricant contains adhesives that make it “stick” to the chain. Due to this, it does not fly out as much when the chain rotates, as other types of it do. Therefore, the bar and chain are less abraded and last longer..

If you drop a good adhesive on your thumb and forefinger, connect them, and then spread them apart, you can see how it stretches between them. Other types will not be able to do this..

Density is an important characteristic. Do not take too liquid grease, as it is quickly consumed. In my experience, as well as the buyers with whom I had to communicate on this topic, Stihl chain lubricant is consumed the longest..

It is also worth noting that if you care about nature, then you can use oil to lubricate the chain, which subsequently decomposes without harming the environment. It is produced on a plant basis. The price will of course be higher.

Pour chain oil into a special tank right up to the neck. It is recommended to refill with the fuel mixture of the saw, since, usually, when a full tank of the fuel mixture is developed, there is still some chain lubricant left. But if you do not add it, then it will be used up before the fuel runs out..

That’s all. I hope you found it interesting and learned something new for yourself. Use only special oils for gasoline and chain lubrication and your chainsaw will last you its full life..
