What gasoline to fill in the Stihl grass trimmer

What gasoline and oil should be poured into chainsaws and brushcutters

It is impossible to say in one answer about all trimmers at once, since each has its own specification.!

So it’s best to find a manual for the grass trimmer you are going to use.

But if we summarize the data, then in most cases AI-92 is recommended, but some models only AI-95. Higher-octane gasoline of the AI-98 marking has not been used anywhere in my memory, respectively, and it is not worth pouring it in, since the engine may not withstand.

Now about the dilution of gasoline with oil. firstly, the oil must meet the API requirement for two-stroke engines with the designation class TA.

But how much, or rather the ratio of oil / gasoline, you need to watch!

But there is a nuance, these proportions can be written in three places:

  • manual
  • fuel tank
  • oil canister

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 the 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.

How to prepare the mixture?

In order for the equipment to serve for a long time and properly cope with its functions, you need to know exactly how much oil you need to add to gasoline for the STIHL chainsaw. Earlier, we found out that it is better to use a lubricant product from the STIHL manufacturer and AI92 or AI95 unleaded gasoline as components. Leaded fuel grades adversely affect the operation of the unit and disable it. With these components, 20 ml of oil is added to the mixture per liter of gasoline. Any violation of the proportions leads to the appearance of carbon deposits on the spark plugs and pistons, as well as the formation of scoring. The oils used can be green, blue or red.

Their presence is easily determined by the color of the mixture. To dilute fuel, often complete with equipment, a special canister is attached. These containers have graduated marks and two holes. The user only needs to fill the tank with the components of the mixture to the required marks, close the lids and mix. Some people use plastic bottles and syringes to measure oil for this purpose. In this case, it is necessary to ensure that foreign particles or water do not get into the container, all this will worsen the operation of the engine.

Gasoline for brushcutters 95 or 92! What’s better?

I decided to take the list of numbers of Sadko service centers and call, ask them the question, which gasoline is better than 92 or 95! First, I called the western regions, the Transcarpathian, Ivano-Frankivsk, and Luvian regions, the answer is only 92, it has a smaller amount of additives, the piston and valve will run longer! in Kiev they said that only 95! in the Sumy region they said 92, also referring to the percentage of additives in 95! In Kharkov they said 92 or 95 take only on a good gas station, only the oil must be of high quality! In Donetsk and Dnipropetrovsk, they said it would be better to take 95! AR Crimea 95 or 92 only at good gas stations!

At a friend of Kalina, after 107 thousand rings on the 3rd cylinder were demolished, the previous owner drove 92, several minders said that it was because of gasoline, that you need to pour 95! now he only refills on vogue 95!

so I’m ready for a constructive dialogue!

Well, let’s start by opening and reading the instructions. But I can say in advance (I have a lot of imported equipment) that it says at least 92nd. In general, I would recommend it. I don’t know about you in Ukraine, but we don’t have a normal 95th in Russia. Only due to additives, chemistry. Suitable for cars, But for brushcutter engines, no chainsaws. They break on it. Therefore, I only use the 92nd.

The instructions say 92-95! I pour oil in mobile1 10v30 synthetics as in the instructions! I called STIHL service centers, in the first they said that 95 is better, they only use it, it is better Okko or Vogue, but take the usual 95. in another service they said that the one I trust is better, I go to 92, at least UAZ, at least a planet, at least slavut! in the trait service they said that it is better to fill in 2-stroke motors 92 for him on the drum, but already where the technology valves are 2 mix and 4 mix, they are very picky about gasoline, and there are only 95! so I’m leaning more towards the usual 95!

And who forbids? Only then do not look for the guilty. And why then was there to ask?

I want to hear the objective opinion of a person who has operated mowers with 92 and 95 gasoline! That is to say I want to extend the service life!

I also found some information on some forum, so I’m generally confused!

I talked with the Germans from the calm, they explain that it is not even possible to store diluted gasoline that is not poured but diluted for more than one week. This is the specificity of oil for two-stroke engines. And they strongly recommend using 92-m gasoline in Ukraine but not 95 m. Since our (Ukrainian) 95 ANY EVEN STEEP is worse than 92 with a cheap refueling. Or if it is possible to use Russian or German gasoline. I have a STIHL-450 hedgecutter, I cut it with both fishing line and knives, just for each case you need to select your own tool. No need to be afraid of knives. the main thing is to follow all the TB points in the instructions. Knives are afraid of stones and wire. So he has served me faithfully for five years. Runs on 92 gasoline. And the air duct was also filled with STIHL 95 for two years, the piston burned, repair 4200gnr. And yet, there is never too much oil in gasoline. And as for the e-trimer, I once held it in my hands. this is a divorce of people for money.

You have a 4T engine with oil in the crankcase. Compared to a 2T engine in which lubrication occurs with a petrol-oil mixture, it is easier for you with gasoline. You can fill in good quality 92-95 gasoline.

P.S In Ukraine, there is a network of gas stations, their gasoline contains more than 10% alcohol, such gasoline cannot be poured into 2T engines, because oil in such gasoline dissolves very poorly. And cars with such gasoline work quite normally.

Good quality in this, I’m not sure that we have such gasoline, but VOG is considered the best gas station in the area! I need to know with what gasoline the engine of the brushcutter will work longer, so I doubt it, I ran it on 92 ANP, but then we did not have Vogue yet! but then I stumbled upon the messages of a forum member Yaroslav 1 and Bell Amore, and each of them proved their case and gave specific examples! That’s when I started thinking! creating a theme, I thought now the dudes of the SC would run in here and tell you why in ODESSA roofing material! I still doubt which gasoline is better!

On good gasoline 92, 95. I understand that your engine is a copy of a Japanese Honda. Answer this question, is there gasoline in Japan similar to our 92nd? What is recommended by 92 is less likely to run into 80 acetone = 95.

Yes, a copy of the GX 35 Honda engine! I think the Japs do not have 92! I got an idea, if you take a 10L canister, and pour 5L 92 5L 95 into it on a vogue! there will be something like 93! do not judge strictly!

Fully podderzhivayu.Even in a car where 95 is registered, you have to fill in 92. Two-stroke from our 95 will quickly fail.

I didn’t claim that you have a 2 ton motor on your car!

dimasldo, you do not bother much about gasoline, refuel the proven one you trust. For your engine, there is not much difference that it is 92, that it is 95. The main thing is to have high-quality gasoline. You better change the oil more often, it will be more useful for the engine.

Well actually yes. As I understand it, it is clean. Then you shouldn’t bother. Clean practically does not deteriorate. I have stood in barrels for years. The mixture with oil deteriorates.

I worked obliquely for 15 hours, changed it 3 times!

I dare to argue about gasoline! It deteriorates, or rather oxidizes and turns into yellow! About 5-6 years ago, my father bought 95 gasoline in the Russian Federation, now I have 30 liters of it left, so he turned yellow, Today he went to the tool center, of Partner STIHL, a boy works there, he has been fixing saws and brushcutters for 5 years already, he said that gasoline oxidizes and negatively affects the piston, there are scratches on the piston! He also said that there is no difference on what gasoline the saw will work! The main thing is that before pouring gasoline for a day, pour it into a transparent container, if after a day no sediment has fallen out, gasoline can be used! Showed examples of gasoline that precipitates!

Well, since you yourself know everything, so why are you asking?

valerich wrote: Well, since you yourself know everything, so why are you asking?

If I didn’t know I didn’t ask, I didn’t know which benz is better than 95 or 92, but I didn’t know that it was going to deteriorate at all! Who responded thanks a lot!

Here’s another nadybal resource that might be interesting! Now for gasoline. the ratio of the gasoline. oil mixture has nothing to do with the brand of gasoline. The brand of gasoline only affects engine detonation. Detonation is the spontaneous explosion of gasoline when compressed. The piston or the knee or the connecting rod also exploded. destroyed, it happens that the head is in half. I do not scare it as it is. About gasoline. imagine a piston moving up the cylinder and compresses the fuel mixture. HOW different gasolines behave when compressed: Gasoline 80 detonates at a compression ratio of about 8-9 and burns quickly after a spark, i.e. the piston has not yet reached top dead center, with a compression ratio of 11-12, and gasoline exploded spontaneously and pressed the piston in the opposite direction and ruined the entire piston. Gasoline 92 detonates at a compression ratio of about 11-12 and burns longer than 80 after spark ignition. That is, in terms of the compression ratio, it fits our tools. gas engines used on the site. Gasoline 95 detonates at a compression ratio of about 12-14 and burns even longer after ignition with a spark. but due to the slow combustion at the beginning of the exhaust gas discharge, it continues to burn and burns the piston and the exhaust tract. In addition, in our country there are 95 gasoline, mostly with additives that increase the octane number, and all the additives remain on the plug and rings. To get more power, with a small volume, the compression ratio is increased to 10-12, so that the mixture is preliminarily compressed more and, after ignition, received additional power. All engines of streamer, chainsaw, pump. (although there may be 4-stroke) are designed for 92 gasoline. Imagine a spark set fire to a mixture with 95 gasoline, and as you know, it burns longer and the combustion process will continue in the muffler, and the fresh mixture that has come in will also partially burn, and part of the piston and rings, towards the outlet window, will be fried with live fire And gasoline 92 burns out before the exhaust phase and only smoke goes into the muffler. As you know, gasoline does not immediately ignite and expand, therefore, the spark jumps before the piston approaches the top dead center, the so-called ignition timing, in these engines it is from 1.5 mm to 3 mm. In the spring, before the first start-up, be sure to prepare the engine, after winter everything is dry in the engine and the compression is weak and dry rings scratch the cylinder, you can lift the cylinder so that this does not happen, I sprinkle honey. a syringe into the spark plug hole about two cubes of the mixture, sometimes more, I crank the engine slowly, I try to start, but it does not start, because the fresh mixture settles on the dry walls of the crankcase and does not enter the cylinder, if there is a mixture enrichment agent, turn it on, or unscrew the spark plug check it if necessary, blow it out and again run the mixture into the cylinder with a syringe, about 2 cubes, it will calm down and start, then warm it up and everything is ready for use for the whole season. On my own I will add: Pour ONLY what is written in the manual! 95 is not better or worse than 92. they are simply DIFFERENT! Even the overcharged!

What gasoline is needed for a grass trimmer and how much oil to pour?

There are quite a few trimmer manufacturers, and the engine (gasoline) can be different (there are two-stroke, there are 4).

What gasoline is clearly indicated in the instructions for the trimmer, even if you have lost the instructions, you can always find it on the Internet (on the manufacturer’s website, for example).

Fill in both 95th (AI-95) and 92nd gasoline, if the manufacturer writes about it.

80th is extremely rare, and the savings here are zero.

If the engine is two-stroke, then the oil is needed for two-stroke engines, again, exactly what kind, read the instructions for the tool.

STIHL TRIMMER FUEL MIX RATIO EASY WAY TO MEASURE

Alternatively, here is the oil for 2-stroke engines “JASO FD”.

The proportions are also in the instructions, much depends on the specific oil that the manufacturer recommends.

The most common option is a 1: 50 ratio.

If the engine is already worn out, or the grass trimmer is working under heavy load, the proportion can be changed, for example 1: 25, or even 1: 20.

If the engine is 4-stroke, then gasoline with small is not mixed, in the gas tank there is “pure” gasoline without oil.

Be sure to find the instructions for the trimmer, there are no general proportions, some kind of universal oil and the octane number of gasoline may be different, the manufacturer of a particular tool clearly describes everything.

Gasoline for a lawn mower: which one to choose and how to dilute?

For those people who have a summer cottage or a country house, very often there are difficulties with the overgrown grass on the site. As a rule, it is necessary to mow it several times per season and get rid of thickets. Currently, there is a wide range of garden and vegetable garden equipment on the market. One of these helpers can be attributed to a lawn mower, in other words. a grass trimmer. For effective and long-term operation of such equipment, it is necessary to fill it with high-quality fuel or properly prepared fuel mixtures.

What gasoline and oil is best for refueling a STIHL chainsaw

The durability and reliability of the 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.

STIHL professional 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 your STIHL chainsaw is the key to a long and successful operation of this unit.
