What kind of gasoline does the chain saw run on?. Oil Preparation.

Can you put 95 gasoline in a chainsaw?

According to current standards, the best gasoline for a chainsaw must be unleaded, high octane and fairly fresh. A high degree of cleanliness from impurities is welcome.

• Filling the fuel system with more than half a year old fuel, negatively affects the ICE traction characteristics, contributes to carbon deposition and detonation phenomena.
• It is desirable for beginners and experienced users to exclude from their attention low-octane gasoline for chain saws as well as cheap motor oils of unknown origin. The use of leaded fuel is not prohibited, but in order to prolong the life of the saw, it is better to refuse its use at the stage of selection.

Practice shows that saving on quality and cost of consumables has a negative effect on the performance of the chainsaw and the duration of its full-fledged operation.

I feed my single-axle tractor “Mole” with 92. Although 76 used to be good. In 15 years, it has never been prepared for winter time. Similarly with the saw and trimmer. Our cottage season ends abruptly and unexpectedly, so I can not prepare. Worked out last year’s mix in 5 liters, it’s fine to start and run.

I’ve been drinking good 92 for years.If 2-stroke, then gasoline with oil (preferably strictly pour without overfilling and underfilling oil. it’s harmful). I only fill up the mix for work. Can’t leave it. The mixture doesn’t last long. It’s better to work in small portions. If there’s not much left, I dump it.On the winter. an empty tank only.

In 4-stroke engines I leave a little gasoline for the winter. But I cut off the gasoline supply to the carburetor and wait until the remainder is exhausted.

I change the oil in a 4-stroke tillage block every spring before I start work.

Experience so far is small, only one winter. All last season, and this one I’m starting, I’m pouring 92 gasoline. Champion oil from the Chinese manufacturer. Then I’ll switch over to “Stilev”. Read the forums. canned for the winter or not. Talked to the forest service, they said don’t bother your brain. Finished the season, put all the tools in the garage. In spring I filled it up and let’s go I tried it and it was ok, it started easily.

The main thing is not to leave in the winter, and in general with a mixture in the tank. Empty and let it work out the rest. The mixture will oxidize quickly.Used STIHL oil, it’s expensive. I’d rather have 92 gas.

For 5 years I leave it as there is gasoline and so I leave it ! Grass cutter and chainsaw work half the time

Liew 100 from Lukoil) hell itself began to mow))) Of course 92 Husqvarna oil, gasoline do not drain for the winter, but before the season poured out and pour a new one, more than two liters of mix do not do t.They say you can’t store gasoline and oil for a long time!

I store it with gas, then I refill it with 92 gas and change the spark plug every season. it starts right away

The mixture is stored no more than 5 days.Then it breaks down and you can’t use it. It is necessary to produce within 5 days. Mixing is convenient in 5 liter bottles. If you need a little mixture then in a special Stilev liter bottle, there’s a spout-cup for oil.I mow with Stihl myself and pour 92, but I pour 95 for 5 years and it’s okay. For the winter, it’s essential to preserve it with a full drain of fuel and a teaspoon of two-stroke oil in the cylinder. And pull the starter a few times.

Why can’t you use it after five days?? And what does it split into?? Into atoms?! When I was a kid, in my dad’s motorcycle, of course, it would split overnight until the tank was practically empty. And now what all of a sudden?? It won’t start or something?

It’s a modern myth of shitty quality. If you remember when I was a kid, my grandpa/grandpa had “Riga” mopeds, they poured all sorts of things into them and they ran. What now?- 5 days of storage, then it splits, drain it in winter.

Then my gasoline isn’t right, since the equipment starts with a month old gasoline!

I mean, they’re driving around in your ears. Since last year it is filled and for spring everything is started. chainsaw, auger, lawn mower. I don’t drain anything if there’s anything left.

Splitting is a modern myth of bullshit quality. If you remember, when I was a kid, my grandpa/grandpa used to pour all sorts of stuff on their mopeds, and it would ride. And now what.- 5 days stored then split, drain for the winter.

For the time being. Pistons don’t wear out right away. It may be rolled, but it is better not to risk. The equipment is expensive and you want to save it. The analogy with Soviet motorcycles is interesting and touching. My Carpathians were also fueled somehow. But it won’t work with Japanese scooters and Canadian snowmobiles. I don’t want to try. It’s the same with high-tech lawn mowing equipment. Here’s the bottle. Prepare the mixture-minutes. All things considered. Is it so hard to follow the recommendations?

What kind of fuel to use for your chainsaw??

The choice of the right fuel is an important and important question. The only correct approach to its solution. a careful study of the user manual, which specifies the type and brand of fuel, the proportions of mixing gasoline and oil, as well as reflecting all the features of the tool. Modern standards require the use of high-octane refined fuel and special types of engine oil.

The choice of gasoline

Many people wonder what gasoline works best on a chainsaw. Most models require clean, high-quality fuel with an octane rating no higher than 90. Sometimes you can find recommendations on the net to mix 92 or 93 gasoline with 95 to increase its efficiency. It should not be done in any case, because more high-octane brands are often counterfeited, and brands 92 or A92 no one will dilute.

So, choosing what gasoline to pour in a chainsaw in the domestic market, it is recommended to use this fuel. It is necessary to ensure that the gasoline was fresh enough, because during prolonged storage it begins to release resins and other elements that degrade the quality. Manufacturers recommend using:

• STIHL STIHL chain saw 180. better to be filled with gasoline grade A90 and higher;
• STIHL 250. runs on at least 90 octane gasoline. Do not use fuels with methanol in excess of 10%;
• Use only unleaded gasoline with an octane rating of 90 or higher;
• Husqvarna gasoline with at least 90 octane rating, may be pure fuel or tetraethyl lead added. Engines with a catalytic converter require the use of fuel-oil mixture made of unleaded gasoline.

As a rule, the owners of such tools use AI92 gasoline, which meets the requirements of the producers. However, gasoline A72 or A80 is good enough for the majority of domestic chainsaws. It should also be kept in mind that failure of a chainsaw due to the use of low-quality fuel is not a warranty case.

Choice of oil

The chainsaw uses two types of oil. engine oil and chain oil (adhesive oil). They should not be confused, because the tasks they perform are different from each other. You can use any gear oil for chain lubrication, although manufacturers always recommend you use the same brand lubricants. Requirements for engine oil are stricter. All the manufacturers are unanimous on this point. you should use oil from the same company that made the saw.

Two-stroke engines have no lubrication system, which is replaced by the presence of some material in the fuel. Carburetor sprays fuel and oil mist, which lubricates all parts in the process. after that the residue is burned up in the cylinder. Unless specifically instructed, any two-stroke oil can be used.

For different models of the tool manufacturers recommend:

• STIHL 180 chain saws are best lubricated with STIHL HP, HP SUPER or HP ULTRA;
• STIHL 250. STIHL HP, HP SUPER or HP ULTRA is the right oil to use. STIHL HP ULTRA shows the greatest performance;
• Partner. any two-stroke oil. Do not use automotive or marine oil. this will cause the engine to break down;
• Husqvarna. Husqvarna two-stroke oil is recommended by the manufacturer. Do not use oil for four-stroke engines, or for water-cooled two-stroke engines.

Important! Not all types of oil are available in Russia, so sometimes it is necessary to change it for other, available types. Synthetic, high-quality materials are considered the best choice.

Why do you put AI-92 in your chainsaw??

Chainsaw engines are underpowered and not suitable for all fuels. That is, their internal combustion engine works with gasoline, which has only certain impurities. If there are other impurities or a different ratio, it can cause an explosion. For example, AI-95 is high-octane, high-quality, elite gasoline. AI-95 is better in terms of safety. it has impurities that prevent it from detonating. But these same impurities can reduce the performance of the chainsaw engine and accelerate the wear of components. You can draw a parallel between pouring such gasoline into the saw and using rocket oil in the car.

Using a lower-octane fuel is prohibited because of the possibility of an explosion.

Chainsaw oil to gasoline ratio

Each chainsaw company adjusts the engines and base carburetors to work with different amounts of lubricant. That’s why the proportion of oil and gasoline for a chainsaw may be slightly different.

Most often, when mixing fuel with oil, manufacturers advise using a proportion of 1:50, or 1:40. This means that 1 part of engine grease must be mixed in 50 or 40 parts of fuel, respectively.

It is relatively easy to put the ratio into a more accessible formulation. For example, 1 liter of fuel contains 1000 ml. If 1000 ml divided by 40 you get 25 ml. This means that you need 25 ml of lubricant for 1 liter of gasoline. The same formula must be used when the manufacturer recommends preparing fuel mix exclusively in the proportion 1:50. This formula: 1000 ml divided by 50. The result is 20 ml. This means that 20 ml of motor grease should be diluted in 1 liter of fuel.

Things are a little different with Chinese chainsaws. Their manufacturers advise to dilute gasoline for chainsaws in the ratio of 1:25. It means that the owners of Chinese tools need to mix exactly 40 ml of lubricant in 1 liter of pure gasoline. This ratio is due to the fact that the quality of assembly and selection of components these chainsaws are slightly inferior to their Western counterparts. In the engines of American, European and Japanese models, the distance between the cylinders and pistons is much smaller than in chainsaws from China. Because of this, the amount of lubricant required to operate the first. much less.

Important hints

To keep your STIHL chain saw productive for many years you should follow these tips:

• Gasoline must be fresh, not from a canister that is a month old.
• Do not use oil for 4-stroke engines. It is not burnt out completely and causes deposits of soot and damage to the cylinder piston group.
• In a 2-stroke engine, the oil must burn without residue, so it is advisable to use “synthetic”, which is characterized by the formation of less combustion residue and smoke.
• When diluting the mixture, it is better to add more than the recommended amount of oil, but within reasonable limits. 5 grams of extra per 1 liter of gasoline will not lead to coking. A larger amount may cause fouling and damage to the cylinder head. Adding 5 grams less than specified can overheat the piston and cylinder.
• Do not use a mixture prepared a month old.
• Do not use moped oil. it is not designed for chain saws because it has a lower rpm rating.
• After the season the mix must be completely used up or drained to avoid loss of petrol properties as well as wear of seals.

What kind of gasoline to put in your STIHL chain saw?

Low-quality fuel may be the cause of failure of your machine. STIHL chain saws are usually filled with unleaded gasoline with more than 90 lead-free additives. AI fuel is fully suitable for this. 92. AI is also used. 95 gasoline, which is used less frequently. It is made on an AI basis. 92, but contains various additives that deposit on the inner engine components and can impair the mechanism. It is acceptable to mix both fuels to achieve the optimum result.

Remember that it is recommended to use fresh gasoline t.к. during long-term storage in closed containers the useful octane properties are lost.

Calculation of fuel mixture proportions

Correct refueling also involves strict adherence to the proportions. For two-stroke engine use 1 part oil to 50 parts gasoline. To maintain this ratio you need 5 liters of gasoline and 0.10 liters of oil. Also remember that such chainsaws can not be equipped with an oil pump, and therefore the use of pure gasoline is absolutely inadmissible.

In the event that the substances for the mixture have different brands, it is recommended to use a ratio of 1:40.

When pelting a new chain saw, 20 percent more oil is added in the first 3 refuelings. In that case, 1:42 is used instead of 1:50 and 1:40 is changed to 1:33.

Wrong mixing ratios can lead to burrs and soot deposits on the spark plugs and pistons.

Rules for the preparation of the fuel mixture

If desired, you can conduct the creation of the mixture on your own hands. It is recommended to do this before using the chainsaw directly. Keeping the already prepared substance for more than 10 days leads to the fact that a chemical bond begins to form between the additives, which reduces the service life of the engine. Specialists recommend to drain the fuel and idle the residue before putting the chainsaw in storage for a long time.

The proportions should be chosen according to the manufacturer’s recommendations. Depending on the model and its specifications the ratio may vary from 1:20 to 1:100 or more.

When mixing the active elements it is strictly forbidden to use waste oil or oil that is not designed for a two-stroke engine.

How the mixing is carried out

You also need to pay quite a lot of attention to the direct process of mixing the components used. As a rule the fuel mixture is prepared in a volume that will be enough for 3-4 refuellings of the device in use. You can only do the mixing procedure if you use a measuring cup.

Among the peculiarities of the matter in question, the following points should be noted:

• Some chainsaw manufacturers come with a measuring jug with markings for fuel and oil.
• In the absence of a special container you can use a canister or a dry bottle. Dosing is conveniently done using a regular syringe without a needle.

After adding all the ingredients in one container, you can proceed to the direct mixing of the components. To do this close the lid of the container and then shake it to get a homogeneous substance.

Working proportions of the fuel mixture

As noted earlier, the proportions of oil to gasoline ratio for gasoline saws can vary significantly, largely depending on the features of the design itself. Examples of mixing are the proportions 40:1 and 50:1. Such a ratio ensures proper lubrication of the internal elements of the installed engine.

in some cases, the concentration of the lubricant can be adjusted upwards to provide more efficient lubrication. An example would be when machining a new tool. In addition, it is also possible to increase the efficiency of construction cooling by adding a large amount of oil to the mixture. Specialists recommend that the oil concentration be increased by no more than 20 percent of the normal concentration.

Practice shows that in most cases the sawyer himself has to adjust the oil concentration in the fuel according to the job in hand. This is due to the fact that as the structure wears, serious breakdowns may occur. With the normal sawing performance the sawing can be done for a long period of time.

Measuring containers

Various containers with markings can be used as measuring containers. Monitoring the ratio is made easier by using the original measuring cup, which is included in the delivery set.

Bear in mind that measuring jars are included in the factory set, even for budget-priced models. However, a standard large-capacity syringe works just as well.

Recommendations for storage

It is not recommended to save time and mix the compound directly in the gasoline saw’s tank. This is due to the fact that it will be quite difficult to achieve the desired result. Recommendations for storage are as follows:

• You can store the resulting mixture for no more than 2 weeks. If the ambient temperature increases, the storage period is reduced to 10 days.
• In some cases, to save money, a previously prepared and expired mixture is added to a new one. But the oil concentration should be no more than 10%.

In order to prolong the work of the fuel system it is recommended to filter the composition through a material made of fibers.

Under the brand

For modern brands, such as Husqvarna, Partner, Makita, Echo, STIHL, gasoline AI-92 is suitable. Today just a colossal number of people complain about the premature failure of chain saws due to bad gasoline. Therefore, some experts recommend pouring AI-95 in such chainsaws.At the same time good AI-95 can “burn pistons”, and again some people have found a compromise and mix AI-95 with AI-92. It all depends on the quality of the gasoline and it’s up to you to decide in the end.

For domestic tools, Ural, Druzhba recommended to take gasoline AI-80. It’s very important that the fuel consumption was minimal.

Gena, Ulyanovsk:

“I would like to make an important observation. It will be useful for owners of chainsaws native to the USSR. Ural or Druzhba. Previously, it was said that such saws needed 50 grams of oil per gallon of gasoline and even 60 grams during break-in. Nowadays oils are of higher quality, so you can safely pour 20 grams per liter! This observation made it much easier for me to use the chainsaw, and got rid of excessive oil. I recommend everyone who has such “old saws” try this proportion for their tools”.
