What gasoline for AL-KO lawn mower

Choosing the right fuel

Most lawn mowers run on gasoline. There are diesel ones, but we will not talk about them within the framework of the article. Petroleum products of the following brands are sold at the filling station:

  • AI-92;
  • AI-95;
  • AI-98.

The N-80 brand has been discontinued and is rare. The octane number (the number after the letters) indicates the resistance of the fuel to knock. The higher the value, the greater the resistance to self-ignition during compression. Gasoline AI-92 is more prone to detonation than AI-95. In the manufacture of motors for lawn mowers, the manufacturer takes into account the resources of the parts and the maximum permissible knock. The instructions for the tool indicate which gasoline you need to use.

Compliance with the recommendations will increase the service life of the mower. If you fill in gasoline with a lower octane number than indicated in the passport, the piston group will quickly fail. Using a higher fuel value is also detrimental to the engine. In Russia, there is no way to increase the octane number by improving the oil distillation process. Therefore, refineries add chemical additives to the fuel. The resistance to detonation increases, along with it, the duration of combustion increases. The result is carbon deposits on candles, rings, cylinders.

Gasoline for a lawn mower: which one to choose and not to lose?

First time you bought a lawnmower with an internal combustion engine? Not sure which fuel to pick? In this article, we will consider the brands of gasoline sold on the Russian market. You will learn which choice to make, whether it is possible to save on octane, how to extend the life of the tool.

The choice of gasoline depending on the type of engine

When buying, check with the seller which motor the tool is equipped with. Petroleum product requirements for two-stroke and four-stroke engines are different.

The four-stroke lawnmower does not require pretreatment of fuel. The design provides two tanks for gasoline and oil. Use the manufacturer’s recommended petroleum product to extend the life of the tool.

Fill two-stroke engines with a mixture of engine oil. The proportion of the composition is indicated on the fuel cap. To understand how much oil you need to add, see the table.

Type Required proportion
Mineral 1:32. 1:35
Synthetic 1:50

Calculation example using a synthetic product:

  • tank volume. 1 l;
  • the amount (1000 ml) divided by 50 (see the proportion in the table);
  • total value. 20.

This means that 20 ml of synthetic oil is needed per liter. If it is not possible to measure the required volume, prepare a larger amount of the mixture. For example, half a faceted glass of synthetic oil is enough for a 5 liter canister. The surplus can be stored in a canister all season long, the quality will not deteriorate.

Preparation of a fuel mixture for two-stroke engines

The video shows how to make a fuel mixture for two-stroke engines. Refueling mtokos, chainsaws and.

As for the gasoline that you need to refuel the lawn mower, it should not be of a higher grade than that recommended by the manufacturer of the equipment. Since the higher the octane number, the longer the fuel burns. This, in turn, can lead to significant problems and premature tool failure.

Everyone knows that gasoline is a highly flammable substance and its vapors are explosive. Based on this, we recommend that you always follow a few simple rules that will ensure the safety of each user:

  • Allow the engine to cool before refueling.
  • Do not work with fuel if there is an open fire nearby, and smoking is also prohibited.
  • To avoid exhaust gas poisoning, refuel and start up outdoors or in a well-ventilated area.
  • It is not recommended to fill the tank completely, it is imperative to leave room for the “expansion” of gasoline, which always occurs when it heats up.
  • Avoid getting fuel on your clothes and shoes.

In general, maintenance of gasoline engines of a lawn mower is a fairly simple matter that does not require any special knowledge and skills from you. For units with a two-stroke engine, you need to learn how to properly prepare the combustible mixture, as well as clean the air filter in a timely manner. For machines with a four-stroke engine, it is enough to change the oil annually and clean the air filter so that it will serve you faithfully for many years.

Fuel selection

Fuel preparation for a two-stroke engine consists in mixing a special engine oil (it is bought in the same place where lawn mowers or car parts are) with gasoline. Mineral oil is mixed with fuel in a ratio of 1 to 32 (or 1 to 35), and if it is synthetic, then the ratio is 1 to 50. all this should be indicated on the package. You can prepare fuel for the lawnmower for the whole season, for this add 100 g of oil to a 5-liter can of gasoline.

To the question: “What gasoline should I use?”. the answer is simple: the brand should not be higher than that indicated by the manufacturer of the lawn mower. The octane number matters. the higher it is, the longer the burning time of the fuel, if you use a fuel of a higher grade, this will shorten the life of your device. The four-stroke engine has a crankcase that contains a lubricant that lubricates the engine, so it is only fueled with gasoline. But it will have to be changed every 50 hours, whatever it may be, since there is no special oil filter.

Only a cooled engine can be refueled, and the tank cannot be filled to capacity, you need to leave a little space for expansion. Of course, safety rules must always be followed.

What kind of gasoline to pour into the lawn mower. outlining

What gasoline to fill in a lawnmower with a four-stroke engine?

And now we will tell you what kind of gasoline to pour into a lawn mower with a four-stroke engine, the main difference of which is the presence of a crankcase. It contains oil for lubricating the engine, therefore, in order for an apparatus of this type to work normally, it is enough to fill it with only gasoline. But there are also some peculiarities here. Because the equipment does not have an oil filter, which means that it is not cleaned, it needs to be changed approximately every 50 hours of operation.

Which gasoline is better than 92 or 95?

Every Russian car enthusiast, especially a beginner, sooner or later asked himself, his friends or specialists a really urgent question: What gasoline is better than 92 or 95? What kind of gasoline is better for filling a car? This question arises primarily due to the fact that. This is a lot. Everyone wants to save money. But after opening the instruction manual of your car, you can see an ominous inscription: Fill in gasoline at least 95 octane. So you start to wonder if it is worth saving or not?

I used to ask myself this question, but the latest increase in gasoline has put everything in its place. I received an answer to the question Which gasoline is better than 92 or 95? precisely, not which one is better, but which one should be poured into your favorite car.

A friend of mine who works in an oil refinery helped me with the answer. He once asked me:
– What kind of gasoline do you pour into your car??
I answer:
– 95th.
– What for? why not 92nd?
– I have written in the instructions.
– I also have it written, but I fill in gasoline 92, instead of filling gasoline 95. And here’s why. The fact is that gasoline 95 is produced from ordinary gasoline with an octane rating of 92. Some additives are added to gasoline 92 that increase the octane number from 92 to 95. Thus, gasoline 95 can be sold at a much higher price. But that’s not the point. The main thing is that these additives, which increase the octane number, are not very useful for the engine, I would say that they are not very useful. This has long been proven in practice. Personally, I have been refueling 92m gasoline for several years, instead of 95th and it’s normal.

After listening to this story, I also decided to try and here is the result. For two weeks I fueled exclusively with gasoline 92. I did not notice any particular difference in the behavior of the car. The fact that the car began to dull or accelerate worse was also not noticed. Idle speed is normal. Dashed off more than 2000 kilometers. There are no comments. But the monetary savings were 15-20%. This is good news. I made my choice!

Conclusion: In practice, which gasoline is better than 92 or 95, the difference was not found. So the choice of which gasoline is better to fill 92 or 95 is yours.

Gasoline octane number

The octane number of gasoline is an indicator that characterizes the knock resistance of a fuel, that is, the value of the fuel’s ability to resist spontaneous combustion during compression for internal combustion engines. That is, in simple words, the higher the “octane level” of the fuel, the lower the likelihood of spontaneous combustion of the fuel during compression. With such a study, fuel levels are distinguished according to this indicator. Research is carried out on a single-cylinder unit with a variable level of fuel compression (they are called UIT-65 or UIT-85).

The units operate at 600 rpm, air and a mixture of 52 degrees Celsius, and the ignition timing is about 13 degrees. After such tests, OCHI (research octane number) is withdrawn. This study should show how gasoline will behave at minimum and medium loads.

At maximum fuel loads, there is another experiment that deduces (OCHM. motor octane number). Tests are carried out on this single-cylinder installation, only 900 rpm, air and mixture temperature 149 degrees Celsius. RHM has a lower value than RHM. During the experiment, the level of maximum loads is displayed, for example, during throttle acceleration or when driving uphill.

Now I think, at least a little it became clear what it is. And how is it defined.

Now let’s go back to the choice. 92 or 95. Any kind, be it 92 or 95, and even 80. When it is processed at the plant, it does not have such a final octane number. With direct distillation of oil, only 42. 58 are obtained. That is, of very low quality. “How so”. you ask? Is it really impossible to distill at once with a high rate? It is possible, but it is very expensive. A liter of such fuel would cost several times more expensive than those currently on the market. The production of this fuel is called catalytic reforming. Only 40-50% of the total mass is produced in this way, and mainly in Western countries. In Russia, much less gasoline is produced in this way. The second production technology, which is less expensive, is called catalytic cracking or hydrocracking. Gasoline with such processing has an octane number of only 82-85. In order to bring it to the desired indicator, you need to add special additives to it.

Gasoline additives

1) Additives based on metal-containing compositions. For example, tetraethyl lead. They are conventionally called leaded gasolines. Very efficient, they make the fuel work, as they say. But also very harmful. As the name implies tetraethyl lead, the composition contains a metal. “lead”. When burned, it forms gaseous compounds of lead in the air, which is very harmful, settles in the lungs, developing complex diseases, such as “CANCER”. Therefore, these types are now banned all over the world. In the USSR, there was a brand AI. 93, it was just based on tetraethyl lead. This fuel can be conditionally called obsolete and harmful.

2) advanced and safer ones are based on ferrocene, nickel, manganese, but most often they use monomethylaniline (MMNA), its octane number reaches 278 points. These additives are directly mixed with gasoline, bringing the mixture to the desired consistency. But such additives are also not ideal, they form deposits on pistons, spark plugs, clog catalysts and all kinds of sensors. Therefore, sooner or later, such fuel will clog the engine, in the truest sense of the word.

3) The last and most perfect are ethers and alcohols. The most ecological and do not harm the environment. But there are also disadvantages of such fuel, it is a low octane number of alcohols and ethers, the maximum value is 120 points. Therefore, the fuel requires a lot of such additives, about 10. 20%. Another drawback is the aggressiveness of alcohol and ether additives; with a high content, they quickly corrode rubber and plastic pipes and sensors. Therefore, such additives are limited to 15% of the total fuel level.

Which gasoline is better than 92 or 95. A few words about the octane number and compression ratio. Really useful stuff

I think many are asking this question on the vastness of the endless Russian roads. What kind of gasoline is it better to pour into your iron horse 92 or 95? Is there a critical difference between them, and what happens if 92 gasoline is used instead of 95? After all, it is about 5. 10% cheaper, and accordingly, there will be real savings from each tank! BUT is it worth doing this and is it not dangerous for your power unit, let’s sort it out on the shelves, there will be a video version and a vote at the end.

  • Gasoline octane number
  • Gasoline additives
  • Compression ratio and modern car
  • What happens if you pour 92 instead of 95?
  • VIDEO VERSION

At the very beginning, I propose to think, what are these numbers, 80, 92, 95, and in Soviet times also 93? Ever wondered? It’s all just this octane number. And then what is it? Read on.

Compression ratio and modern car

Actually, why did I start talking about the octane number and additives, but because you need to take into account the spontaneous ignition of fuel or the so-called detonation in modern units.

The fact is that manufacturers, in order to increase power and reduce fuel consumption, slightly increase the compression ratio in the engine cylinders.

Here’s some useful information:

  • For a compression ratio of up to 10.5 and below, the octane number of AI gasoline is 92 (we do not take into account the TURBO engine options).
  • From the mark 10.5 to 12. fill in fuel not lower than AI. 95!
  • If the compression ratio is 12 or higher, then it is recommended to fill in at least AI. 98
  • Of course, there are still very rare gasolines, such as AI. 102 and AI. 109, for them the compression ratio is 14 and 16, respectively.

But for turbocharged units, fuel recommendations are not lower than 95th. I would also like to note not to confuse the compression ratio with compression.!

gasoline, lawn, mower

So what happens, IN THEORY, if we put 92 gasoline into a motor that is rated at 95? YES everything is simple, fuel from a high compression ratio will ignite spontaneously, “mini-explosions” will occur. that is, the destructive effect of detonation will manifest itself!

And what is the danger of detonation? Yes, everything is simple, burnout of the gasket between the block head and the block itself, destruction of rings (both compression and oil scraper), burnout of pistons, etc.

BUT this is how I wrote above. ALL THIS IS IN THEORY! ESPECIALLY WITH US IN RUSSIA! Why am I saying this. Many manufacturers have understood that it is VERY DIFFICULT to find high-quality gasoline (and now we are talking about the 95th option), if possible, even in the capital regions (I am already silent about small towns). Often gasoline is “badyazhat” so that it is unrealistic to reach the octane number of 95. I remember a couple of years ago, I read an article with an experiment. where samples were taken from a large number of gas stations in the capital, and only in 20. 25% of cases gasoline approached the norms, the rest were far from 95 and even 92. Just think about it! How do you check the quality yourself? That’s right. NO.

So if you fill in such a low-quality fuel, the engine will immediately shut down? Immediately? Not certainly in that way. Cars are smart now, and it is precisely to prevent your motor from going “out of gear” that the knock sensor was invented, it allows the motor to work with a different octane number. It monitors the mechanical vibrations of the engine block, converts them into electrical impulses and constantly sends them to the ECU.

If the pulses “go beyond the normal state”, then the ECU decides to correct the ignition angle and the quality of the fuel mixture. Thus, a modern engine designed for 95 gasoline will work quietly even at 92.

But! Such work will be successful at low and medium revs, at high revs (almost maximum), the knock sensor does not work as efficiently, therefore, it is NOT desirable to “fry” on a low-octane mixture!

Let’s summarize.

What happens if you pour 92 instead of 95?

In fact, the difference between 92 and 95 gasoline is minimal, only “3 numbers”. If you go to refuel in a company that guarantees you exactly “hard indicators”, that is, “92 is 92”, and “95 is 95” and YOU WILL BE SURE OF IT. That difference will be more likely for your engine at high speeds, and not in a significant (up to 2. 3%) loss of power, and fuel consumption will also increase by this percentage.

And what is most interesting, if you do not often spin your power unit up to 5000. 7000 rpm, but move from 2000 to 4000, then 92 will not give you any negative moments. Nevertheless, the electronics will regulate everything by itself.

Prejudice. that valves can burn out, there is no such thing. Burnout of valves was typical for leaded types that had metal additives. High-octane leaded gasoline could harm an engine configured to use AI-76 (and it did not have electronic ignition angle correction and fuel injection). But now there is simply no such danger, because such fuel has long been banned.

BUT IN IDEAL! Fill with the exact fuel recommended by your manufacturer. After all, if suddenly a new engine shuts down, and it turns out that the breakdown is related to gasoline, then you will find yourself in a very expensive repair, AND AT YOUR OWN EXPENSE. Saving 10% on gasoline will “come out sideways” for you.

What end result would you like to draw. to each his own, if your motor is not designed for the 92nd, then you should not pour it! Yet it can be fraught! However, if you fill in then a modern engine, automatically, will adjust the ignition angles and you may not even feel the fuel change (THAT IS, and you can drive on the 92 without spinning your engine to the maximum). But if a breakdown occurs, and the warranty finds out that the wrong fuel has been filled, REPAIR WILL BE AT YOUR EXPENSE! And this, for sure, is not worth 2. 3 rubles saving per liter.

Now a detailed video version, we are watching.

This concludes, I think my article was interesting to you, sincerely your AUTOBLOGGER.
