What gasoline to pour into a chainsaw?
According to experts, you should use unleaded gasoline, obtained by adding lead-free additives, the octane number of which exceeds 90. For foreign models, it is required to fill in gasoline of higher grades and use branded oils from tool manufacturers. The AI-92 grade fuel is considered perfect. How to dilute gasoline for the Stihl 180 chainsaw? In this case, oils are meant in a mixture of 1:40. AI-95 fuel is also quite suitable for it, but according to professionals it is better not to use it for chainsaws.
The fact is that it is made on the basis of AI-92 with the use of certain additives that change the quality of the fuel. These components are deposited on the inner parts of the tool and, upon reaching a critical mass, begin to flake off, disrupting the operation of the mechanism. The best option is to follow the instructions that come with the selected model. It is recommended to use fresh gasoline, because during long-term storage in containers, octane properties are lost.
Chainsaw “Stihl”: which gasoline oil to use?
A number of manufacturers that produce equipment also develop their own consumables that are adapted to the operation of a particular engine. So the Stihl company produces oil exclusively for its equipment. It is equipped with special additives that can compensate for the quality of the fuel, improving lubrication and cleaning of the fuel mixture. It should be noted that Husqvarna HP oil is universal and can be used for all chainsaws. It can be applied at a temperature not lower than 10 degrees.
And also for two-stroke engines, products of the following brands are used: Sadko, Kraissmann, Oleo-mac Prosint. If you use a Stihl chainsaw, how much oil should you add per liter of gasoline? The ratio will be 25 ml of additive per liter of fuel. It must be remembered that there are oils for chains and motors. They are intended for different purposes and are not interchangeable. The use of chain oil for the preparation of a combustible and lubricating mixture leads to tool breakage.
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 manufacturer Stihl and unleaded AI92 or AI95 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.
Fuel consumption
One of the most important questions that arises from the owners of the saw tool, because everyone wants to know what he can count on.
The volume of almost all tanks is approximately 500 ml. If the power of the chainsaw is 2 kW, then the consumption of the fuel mixture will be approximately 1.2 liters per hour of operation. To put it simply, such a tool will be able to work at maximum speed for half an hour without interruption. If the chainsaw is not as powerful, then it will have a smaller tank volume. So the user can independently control the fuel consumption.
Over time, the user will learn to service his tool without any help. The main task will be to preserve the economic unit in good working order, using high-quality fuel mixtures. Observe safety rules when preparing flammable liquids. This will help to preserve the instrument, as well as not harm yourself and the environment.
Dirty gasoline
Some owners of chainsaws are sure that if the tool works in conditions of constant dust (there is even an air compensator in the carburetor in case of a clogged air filter), it means that it is capable of swallowing gasoline with pieces of rust, and working with small pieces of metal will go to lubricate the chain, so?
This is another common misconception, never use gasoline from the bottom of a canister (especially a rusty one). The chainsaw has a carburetor, in which there are small channels that can clog up from these small particles, which in turn will lead to damage to the chainsaw and contacting a specialized workshop.
Consumer reviews of Stihl saws are mostly positive. It is lightweight and affordable. There are some complaints about the low power of the instrument. But for occasional use at home, it is quite suitable. And if you use the correct proportions of oil and gasoline for your Stihl chainsaw, it will last for many years.
A little bit about motors for beginners
Those who bought a gasoline mower for the first time, and I’m talking about the new owners, will surely go online sooner or later for certain questions. what is the ideal fuel for it. I myself remember myself out of inexperience. Fortunately, today the Internet is to help.
- Let me remind you that the trimmer model Impulse BT 5200 is ideal for cleaning a garden with the mower that I used to mow the grass, because it is first of all lightweight, not whimsical in maintenance, it “eats” almost any gasoline and, of course, is mobile. I want to say one thing, it is definitely not worth saving on the quality of gasoline for the trimmer.
So, let’s continue. Gasoline mowers, as far as I am concerned, meet with a two-stroke engine and a four-stroke engine. The difference between these engines from each other lies in the number of revolutions made by the engine. If we consider a two-stroke engine, then in one cycle there are two piston cycles, respectively in a four-stroke. four. Why am I saying this, and all to the fact that the second “eats” a little more, but for your garden and nature in the forehead, the second type of engine is safer.
What gasoline to pour into the mower. experienced advice
I am glad to welcome you again to my gardening blog. In a personal note, they often began to write words of gratitude on social networks for the post about, how to clean an area overgrown with grass in the garden or vegetable garden. Many talked about their personal experiences and shared tips. I listened to many and made a conclusion. Due to the fact that most of you asked me about what kind of gasoline to pour into the mower, with what it needs to be mixed and in what quantities. I decided to devote a separate post to this.
I want to note right away that your mower has worked for more than one season and mowed a lot of grass, it is imperative that it be properly maintained. You don’t need to have any special knowledge, you just need to listen to my advice and remember them. We arm ourselves with a pen with a notebook and write it down, and some may just remember.
What gasoline to pour into the mower
Honestly, what kind of gasoline you pour into your car and at what gas station, I recommend that you pour it into a gasoline mower. Personally, my choice fell on the AI-95 and I buy it at Lukoil. I agree that many of you will begin to argue with me about the high price and low-quality fuel, I will cut you off right away, where gasoline is, I buy 100% good.
But this does not mean that if I fill the AI-95 in my trimmer, then the AI-92 does not fit, no. But below 92, I definitely do not recommend pouring into the mower tank. Honestly, I have never poured 98 and 100 gasoline into the mower. If any of you tried, please share your experience.
I note that if the trimmer is new, you just bought it, be sure to look in the passport, which brand of gasoline the manufacturer recommends. Your mower may even run on diesel fuel, just kidding of course.
How to dilute gasoline with mower oil
Before starting to consider this issue, especially if you are new to this business, I do not recommend mixing oil with gasoline already poured into the mower tank, since you will not be able to get a perfectly homogeneous fuel mixture 100%. Some craftsmen can and will be able to do this, but in this case the trimmer will have to be shaken strongly, then failure is not excluded. Given the not light weight of the mower, hardly anyone will do it.
- Let’s take a look at the capacity of the tank. A standard tank, no matter what mower you have, will not put in more than 1.2 liters of gasoline. Honestly, I never saw it again, although I had quite a few mowers.
- The easiest way to mix fuel is in a liter, plastic bottle. Well, now the question itself, tormenting many beginners, is how much oil is needed in gasoline for a mower? Perhaps many of you have observed such a picture as a neighbor in the country league in a tank of red gasoline? Well, what did everyone remember? So this is gasoline mixed with oil. Any engine definitely needs lubrication, so gasoline must be mixed with engine oil for mowers, but which one, you will find out in the next post. Typically the oil is labeled for: scooters, motorcycles, gasoline mowers.
- Note that it is a very bad idea to dilute gasoline with oil by eye, so you will definitely need some kind of measuring vessels. If everything is clear with a liter bottle, but with oil, I think for many, not a little. If you used a plastic bottle for mixing, say from under the “Sprite” like me, then you should not store the gasoline diluted for the mower in it, use the mixture for one refueling, since otherwise the gasoline will quickly eat away at the bottle and you will “dirty” the area in my garden.
How much gasoline to mix with mower oil
To mix and pour gasoline into the tank, you will need: a liter, plastic bottle, a 10 ml medical syringe, a watering can and a can of gasoline. A watering can is necessary in order to carefully pour the resulting gasoline into the mower tank in order to avoid accidental spillage.
We need a 10 cc syringe to add 20 ml to a liter of gasoline. Those. 2 full syringes must be injected per liter of gasoline. If any of you manage to find a 20 cc syringe, it will be even better and faster. Note that you should not fill a liter bottle up to the neck with gasoline, since you will need to mix the mixture thoroughly and get a red, homogeneous fuel.
Advice: pour half a liter of gasoline into the bottle, then pour in 2 syringe oils, mix everything well and only then add the remaining half a liter, and then everything into the tank through the watering can. As you can see, everything is simple.
What gasoline to fill in the scooter?
What threatens the wrong choice of gasoline?
Deciding which gasoline is best for a scooter is not entirely correct, since each technique has its own recommendations. Simply put, if a high-quality A-95 is poured into a moped operating on the A-92, its systems will begin to function incorrectly.
Poor quality or unsuitable fuel will cause:
- Fuel system malfunctions. The injector or carburetor of the scooter will simply clog up with additives.
- Carbon deposits in the combustion chamber. If gasoline does not burn well, black deposits appear on the piston and spark plug. Because of this, the scooter loses momentum or starts to start badly.
- Engine overheating.
And these are just some of the problems a rider may face.
Tips for choosing fuel for your moped
Before using the scooter, you should study its documentation. It is in it that it is indicated which gasoline is best used for a particular scooter. These manufacturer’s recommendations will help to avoid a lot of problems and increase the resource of the moped.
Important: Use gasoline with the correct octane rating. If the fuel is selected incorrectly, the scooter engine will overheat and work incorrectly, as well as increased piston wear.
But even if you only fill the scooter with the correct gasoline, you need to watch out for:
- Fuel quality. Remember that the desire to save on gas can backfire. For example, low-quality fuel is one of the reasons why a scooter won’t start or engine speed decreases. Always refuel at the approved places, even if the price of fuel is higher there.
- Scooter operation after refueling. To decide which gasoline is better to fill in the scooter, observe the “behavior” of the moped. If, after refueling, the moped began to “twitch” or there were dips in the engine, then drain the liquid and flush the fuel system.
For the scooter to work properly, forget about any experiments with fuel. It is highly discouraged to use octane correctors or additives that optimize gasoline consumption. All these “tests” can harm the engine and the fuel system of the moped.

Almost all scooter owners are not interested in fuel quality and characteristics. But it strongly affects the operation of equipment, and can lead to a breakdown of the carburetor, a decrease in power or a deterioration in the dynamics of the apparatus. This means that the rider must definitely figure out which gasoline to put into the scooter and how to select the right fuel.

The choice of gasoline for 2t and 4t scooters
Usually, the documentation for the scooter contains all the necessary information about fuel and oil. But what if the manufacturer did not indicate the octane number of the fuel or the instructions were lost? In this case, the rider needs to build on the engine parameters (compression ratio).
So, if you are thinking about what kind of gasoline to fill in a 2t scooter, then try the A-92. Almost all scooters with a two-stroke engine “eat” such fuel without any problems. There are exceptions though, like Yamaha or Suzuki 2-stroke machines. A-95 can also be poured into the equipment of these brands.

But with four-stroke mopeds, it’s a little more complicated. In this case, the rider will have to consider:
- Reliability of the moped.
- Compression ratio.
- Engine volume.
- Limit turns.
If you cannot decide which gasoline to fill in a 4t scooter, then stop at the A-92. But always follow the work of the moped, if the slightest problems are observed, go to the A-95.
Note: Almost 80% of all Japanese and Chinese scooters operate on A-92.
Which gasoline is better than 92 or 95? What to fill?
Many motorists are faced with the question of choosing gasoline. Which one to choose. 92 or 95? Or maybe the 98th? Naturally, a modern car will run on almost any gasoline with an octane rating higher than 92, but in pursuit of greater throttle response, speed, dynamics, the car owner begins to experiment with octane numbers in his gas tank, sometimes forgetting even about the recommendations of the automaker. But in all this big question, the main thing is rather the quality of the gasoline at the gas station you have chosen.
It sounds a little childish, but the best gasoline will be the one that is produced in accordance with all GOSTs and standards, that is, real. Probably, every car owner has come across disastrous results in the operation of a car after refueling with dubious gasoline. And after such experiments, each owner has a so-called “own” gas station, on which, he is sure.
How to choose a gas station for yourself?
Of course, if you just bought your first car, then you simply have no experience in choosing a gas station and gasoline. The advice of friends and acquaintances can come to the rescue, which, of course, you will check yourself experimentally. If no one can recommend a gas station to you, then in every city there is a forum where other car owners discussed such issues. If you are the owner of a diesel car, then the issue of choosing fuel for it needs to be approached even more carefully, since breakdowns due to low-quality diesel fuel can be quite serious and entail high costs.
And now, when you have decided on the fuel manufacturer and its filling station, the last question remains at this stage, which both beginners and experienced drivers face. what octane gasoline should be poured into the gas tank? We will only touch on gasoline, since everything seems to be clearer with diesel fuel, since the choice is not large. Everyone knows that now the brands of gasoline are mainly 92nd, 95th, 98th. We will not consider here some branded brands of gasoline from a number of large manufacturers; the car owner will learn more about them at branded gas stations of large chains. And many experienced drivers will say that such brands are more of a marketing ploy. Let’s go back to the main brands of gasoline. The number in the name of gasoline means the octane number, which characterizes the resistance of the fuel to spontaneous combustion during compression. Some car owners are of the opinion that the higher the octane number, the better the car will work, drive faster and have other positive qualities. Others assure that, for example, the 92nd, on the contrary, is cleaner in comparison with the same 95th, and therefore it saves the engine better. But this is by and large speculation. Of course, there are some theories. But still it is better to listen to the recommendation of your car manufacturer to use the gasoline of the brand that he indicates in the owner’s manual and writes on the back of the gas tank flap.
Using the wrong gasoline can lead to abnormal engine operation, damage to spark plugs, valves and other problems. Therefore, in this matter, you need to listen to those who are responsible for the assembly and operation of the engine.
Bon appétit!
First we fill in AI-92. When the trip computer of the first Vesta issued dashes (the minimum numerical remainder of the power reserve is 30 km), we prepared for the fact that the engine was about to stall. It was not so! As it turned out, cars easily pass several tens of kilometers before the engine stops.
Vesta showed absolutely the same average consumption of “ninety-second”. 6.7 l / 100 km. We take it as a starting point for subsequent measurements. An interesting detail: the trip computer of the five-door SW Cross gives out consumption almost without twisting, but the sedan underestimated the result per liter (it showed 5.7 l / 100 km in this mode), and the alignment was repeated in subsequent measurements. Very strange behavior. the constructiveness of the counters is the same.
We pass to AI-95. Both testers failed to catch the difference in the behavior of each of the cars on the higher octane fuel. The resulting fuel consumption was not surprising either: the SW Cross wagon dropped one “top ten”. up to 6.6 l / 100 km. A less powerful sedan saves a little more: minus 400 ml, the result is 6.3 l / 100 km. But given the same ride feel, why pay more? Without a calculator, it is obvious that in such modes it is cheaper to drive the AI-92.
For dessert. AI-100. And then a surprise awaited us. Neither SW Cross nor “simple” Vesta could improve the result of the “ninety-fifth”! Elite fuel did not give any advantage, and the elasticity of the 1.6 engine was even worse. Although this is not such a sensation: almost five years ago, we already tested the Chevrolet Cobalt and Nissan Almera sedans in a similar way (ЗР, № 12, 2013), and then the “premium” AI-98 was also not surprising.
But this is driving in a steady state. Perhaps instrumental measurements of dynamics will open our eyes?
Should I upgrade to 92nd? Experiment ZR
Russia is one of the largest oil-producing countries, but our for gasoline do not fluctuate with it, and premium AI-98 and AI-100 have jumped far beyond the psychological boundary of 50 rubles per liter. And the eternal dispute about the optimal choice of gasoline flared up with renewed vigor.
Many suddenly remembered that their cars can be refueled “in ninety-second”. and for the sake of economy switched to it.
Others are still convinced that the expensive “ninety-fifth” and even more so “ninety-eighth” provide the car with the best dynamics. And with a quiet ride on high-octane gasoline, they say, the consumption falls. and it will come out even cheaper than on the “ninety-second”!
Do similar theories work for cars with modern, but not highly accelerated engines??
We took two editorial Vesta. Sedan with a 1.6-liter engine producing 106 hp. and the AMT robot symbolizes the choice of a person who is not in a hurry: you don’t need a lot of power, the box switches itself. that’s nice. SW Cross station wagon with 1.8-liter 122-horsepower engine and manual transmission will certainly be preferred by those who want to always have a “headroom under the pedal”.
At the stand
All dots above the “i” have placed the measurements on the dyno. Inzhkar has kindly provided the latest professional Dynomax dynamometer for our testing. Any measurements can be taken on it, and thanks to the powerful air blowing system, the test does not turn into torture for the car’s cooling system.
We spent more than one hour “on the drums” and received graphs of the power of both engines on different gasoline. On AI-92 and AI-95, the cars produced results very close to the passport values: the Vesta 1.6 sedan showed 103.5 and 103.6 hp. respectively (106 hp declared), and the Westa SW Cross 1.8 station wagon produced 119.3 and 119.7 hp. (declared 122 hp).
Curiously, the curves of power and torque on the “ninety-second” were even a little smoother. And at the “hundredth” power. did not reach the parameters declared by the manufacturer 9-10 “horses”! Now it’s clear why the dynamics have barely changed.
With device
With a professional measuring complex VBOX, we first measured the acceleration time to hundreds. The station wagon with “ninety-second” gasoline in the tank gained 100 km / h in 12.0 seconds. On “ninety-fifth” gasoline, he accelerated more fun: 11.3 seconds. Maybe AI-100 will breathe even more power into the motor? Alas. the same 11.3 seconds. Like a carbon copy. history with consumption, only seconds instead of liters.
Sedan? Long 14.8 seconds to the first hundred on “ninety-second” gasoline. ardent greetings from the AMT robot with its rubber switches. On the AI-95, the 1.6 engine cheered up a little: minus six tenths of a second.
And finally, the “hundredth” gasoline showed itself, which allowed it to run out of fourteen seconds and improved the result on the “ninety-second” by almost a second.
Now. transitional regimes, or elasticity. Acceleration from 60 to 100 km / h in fourth gear and from 80 to 120 km / h in fifth.
The elasticity of the “cross” Vesta in the transition from “ninety-second” to “ninety-fifth” improved slightly. The gain is a few hundredths in different modes, whether it is acceleration from 60 to 100 km / h in fourth gear or from 80 to 120 km / h in fifth. The most noticeable difference was recorded during acceleration in fifth gear from 60 to 100 km / h. more than one and a half seconds were won.
AI-100 gave nothing even here. Several hundredths of a second in all measurements of the elasticity of SW are not even crumbs, but fleas. The sedan did not at all demonstrate any advantage in elasticity on different fuels. over, on the “hundredth” gasoline, it even worsened!
How so? Indeed, in theory, the opposite is true!
Menu selection
How to explain such strange results? After all, the higher the octane number, the, in theory, the better the economy and power characteristics. That’s how it is, but not always.
The fact is that the external speed characteristics of the engines are removed by the plant on AI-95 gasoline. they are exactly what are stated in the passport data. Ten or fifteen years ago, even in cars with simple eight-valve engines, AVTOVAZ allowed only “ninety-fifth” to be injected. And it is this gasoline that is still recommended for Grants, Kalina, Priora and Niva!
And why on other front-wheel drive cars with the same 106 ‑ horsepower 1.6 engine, the permissible grade of fuel depends on the model? Marketing! Competitors allow “ninety-second”. and in the struggle for a buyer, AVTOVAZ is forced to make concessions. That is why AI-92 gasoline was included in the list of acceptable grades. For cheaper gasoline, the settings of the control unit were changed, which entailed a slight decrease in engine power and car dynamics. What we have fixed.
And motors are simply not calibrated for more expensive AI-98 and AI-100 gasolines. The control unit is sharpened for engine operation at a maximum of “ninety-fifth” and does not adapt to higher-octane gasolines. Consequently, the power does not grow either. Of course, in some narrow transient modes, the “hundredth” gasoline is able to give a certain increase (for example, in the acceleration efficiency from 80 to 120 km / h), but it is not so significant and will be washed out against the background of other indicators.

What is what
In each Vesta, in turn, we fill in Lukoil Ecto gasoline of different grades: first AI-92, then AI-95, and for dessert. elite AI-100. The instruction manual requires observing only the lower bar. this is AI-92 gasoline. No upper bound.
We will compare not only fuel consumption, but also dynamics, and then drive the cars to a dynamometer. in order to determine the maximum power and torque on the wheels using instrumental measurements.
The method for measuring fuel consumption is extremely simple. We burn out the remains of gasoline in the tank until the engine stops and fill in ten liters of test fuel. We develop it until the engine stalls again, and record the mileage traveled. By simple recalculation, we get the average fuel consumption.
The races were carried out at the same time in similar weather conditions. To minimize the measurement error, the canisters were filled on one dispenser (from the corresponding pistols, of course) at the same gas station.
The driving mode is a quiet highway. We keep 110 km / h evenly. Each car is driven by the same driver throughout the test. to avoid scattering results due to “change of leg”.
