Gasoline to oil ratio for grass trimmer with table. The first run-in of the lawn mower
Hello! Purchased a Prorab 8406 1 grass trimmer. How to dilute petrol with oil correctly and in what proportions? I couldn’t find the original Prorab oil, so I bought Hungsvarna HP. In the manual to the trimmer it is written from the outside oils it is possible to use oils of a class SAE MIF\4, API TC-TB. In the case of using a different brand of oil, the proportion of fuel mixture does not change. Standard mix ratio 1:25. But in a specialized store “specialist” who sold me the oil Hungsvarna HP strongly advised to dilute the oil in 1:50 (as written on the oil). The actual question: if the manual says dilute oil to 1:25, and on the oil is recommended 1:50, then in what proportion dilute? How much is 1:25?? 40 ml? I won’t block the engine if I run it at 1:50? 2. What’s the right way to run-in an engine?? There is nothing in the manual other than start up and shut down. Maybe you don’t need a running-in period? I read that there are grass trimmers that you can use immediately after you buy them.
Do I have to grease the gearbox before use or is there factory grease already installed?? Hope to hear from you, thanks!
1) Gasoline is ALWAYS diluted with oil in the proportion indicated on the can of that oil! You can use any oil for two-stroke products (chain saw, chain trimmer, etc.).) you can use any two-stroke engine oil, except boat two-stroke engines. You should use oil from a legitimate store where you are unlikely to buy fake or counterfeit products. Better to get Husqvarna or STIHL oil. STIHL oil must have a sealed neck. Beware of counterfeit products. There is a risk of ruining the piston immediately. 2) There is no running-in of two-stroke products! PLEASE REMEMBER THIS! All two-stroke products are high rpm and like to run exclusively at full throttle! No half gases are allowed! This causes incomplete exhaust and clogs the walls of the piston rod with oil deposits. Piston scoring as a consequence. So full throttle and every 25-30 seconds do a 1-2 second throttle dump to give the product a break and return to normal temperature. 3) The gearboxes on direct driveshaft brushcutters must be relubricated every 20 hours. The oil comes out of there naturally during operation. This is done to keep dirt, dust, etc. out of gearboxes with grease. д. So if you don’t want to get a gearbox replaced, put some special gearbox grease in it every 20 hours. It is not difficult and the whole operation takes no more than 3 minutes. The tubes of grease are sold in every garden equipment store and cost from 100 to 300. 1 tube is enough for 3 years- The concept of running in the tool is reduced to running under load during the first two or three tanks of fuel. For example, when cutting not dense, low grass or when sawing dry, not large wood. You should never run the tool through several barrels of oil while it is idling. As a result of such running-in, carbon deposits are formed on the cylinder windows, piston and muffler, which negatively affects the life of the engine.
Grass trimmer, or lawnmower. a tool you can’t do without in the household. However, its reliability, efficiency and long service life depend on many factors.
For example, the quality of fuel. This means that you need to properly select the oil for the grass trimmer, observe the proportions when adding it to gasoline and the rules of filling the device.
The gasoline-oil mix you choose for your brushcutter must meet the required specifications, as listed in the owner’s manual. It is important to note that quite often domestic producers label their products slightly differently from the American or Japanese classification. Russian producers of lubricants, as a rule, put a 2T marking on all oils designed for two-stroke engines. Often in the store shelves one can find oil cans marked “self mix” or “pre mix. In the first case, this means that the oil does not require any additional manipulation, just pour the gasoline and oil into one container, and mixing will occur without human intervention. In the second case, respectively, the mixture must be shaken or agitated to bring it to the desired consistency.
As one can see, the existence of different classifications of lubricants suggests that it is necessary to use oils in two-stroke engines. This is explained by the fact that the fuel mixture without lubricant fairly quickly put out of operation the engine, which will not be lubricated properly. Gasoline and oil form the necessary environment, which reduces detonation, removes excess debris (waste products from the combustion of gasoline products) and protects the inside of the engine from wear and tear.
It is important to remember that using the wrong oil classification can cause engine damage or clogging. It would, of course, be repairable, but in order to prevent possible damage and to minimize its probability it would be better to study the instruction manual, find out the engine displacement of the two-stroke engine installed on the brushcutter and use only petrol and oil that will suit this model in all its parameters.
Quite often, in the recommendations section (and sometimes on the label), the manufacturer indicates the partner companies whose gasoline and oil they recommend for their models. often than not, the fuel and lubricant recommended by the manufacturer are best suited to the grass trimmer.
First of all, you should immediately exclude all oils of unknown (garage, basement) origin from the list of actively used lubricants. Usually it is not easy to dilute such oils because of unclear base, composition. As a rule, the labels of unbranded manufacturers are not replete with information, covering only general information, without elaboration. It is highly not recommended to dilute and dilute such oils as AC-10 and ACZp-10. The origin of these lubricants is usually quite obscure, so it’s better to prefer the tried-and-true brands that thousands of people around the country use every day.
A distinctive feature of all oils for two-stroke engines is the fact that the manufacturers dye them in a color that contrasts with gasoline. The liquid is translucent, viscous in consistency, slightly yellowish, but not thick. Usually, we are talking about three colors: red, green and blue.
Do not forget that the color has no effect on the classification (as is often the case with antifreeze).
Under no circumstances should you use oils from a line not intended for the grass trimmer. This can extremely adversely affect the operation of the power unit, lead to increased fuel consumption, soot on the plugs and a number of other problems that will have to be identified and eliminated. It should be noted that if the fact of using oil that is not included in the tolerance is established, the seller has every right to remove the machine from the warranty. It means that you will have to replace the defective parts at your own expense, and no exceptions will not help here.
If purchased liquid does not have declared qualities (for instance, too liquid), you should not mix it with petrol under any circumstances. The best way is to return such oil back to the store, explaining to the seller the reason for the return.
What kind of gasoline to put in the gasoline trimmer? How to dilute gasoline for a lawnmower
Any owner of a country site has been faced with the task of mowing. the lawnmower is needed much more often than a chainsaw or a single axle tractor, because grass grows faster than trees and bushes.
In this connection, the question inevitably arises, what fuel mixture to pour into the trimmer for grass? The petrol and oil mixture must be prepared in the right proportions in order to ensure high engine performance.
Possible consequences that can be caused by too rich or, conversely, too poor gasoline mixture in a trimmer will be discussed below. But first of all it is necessary to understand the role of oil for two-stroke engines, which are most often equipped with gasoline trimmers.
The main difference between the principles of operation of a two-stroke and a four-stroke internal combustion engine (ICE) is that in the case of a four-stroke unit, lubrication of the rubbing parts takes place with the help of a crankcase and an oil pump. The power of a four-stroke engine makes it possible to run this unit.
A grass trimmer with a two-stroke engine requires a mixture of gasoline and oil to lubricate the entire system (cylinder and pistons, crankshaft, bearing supports). To properly dilute and prepare such a mixture for the grass trimmer, there is a special classification, often presented as a table.
Oil in trimmer is not different from lubricants intended for other gardening equipment, equipped with a two-stroke combustion engine. It has the same composition, additive package and detergency properties. Let us take a closer look at the American classification of oils, or, as it is commonly called, API.
- TA Group designed for use in air-cooled two-stroke trimmers and mopeds. Claimed capacity of devices from 50 cc.cm up to 200 cc.see.
- Group TV It is also used in trimmers and other gardening equipment, only with a higher engine volume.
Remember that TA and TV groups are not interchangeable, they may have different gasoline and oil ratios.
Their classification of oils also exists in the Japanese. Unlike the conventionally accepted American classification, the Japanese classification is mainly based on ecological standards.
- FA Group Designed for use in trimmers and other appliances for countries where emission standards are quite low.
- Group Designed for trimmers with a two-stroke engine, where the legislative requirements to the exhaust are much higher.
- FC group for trimmers, where the requirements for gasoline and oil exhaust are minimal. zero exhaust.
The other classifications are not intended for trimmers.
The mix of petrol and oil you choose for your brushcutter must comply with the necessary requirements, indicated in the manual. It is important to note that domestic manufacturers often label their products slightly differently than the American or Japanese classifications. Russian lubricant manufacturers, as a rule, put the 2T designation on all oils intended for two-stroke engines.
Often you can find oil cans with markings on them on the shelves “self mix” or “pre mix“. In the first case it means that the oil does not require any additional manipulations, just pour the gasoline and oil in one container, and mixing will occur without human intervention. In the second case, respectively, the mixture should be shaken or agitated to bring it to the desired consistency.
As you can see, the existence of different classifications of lubricants suggests that the use of oils in two-stroke engines is necessary.
This is due to the fact that the fuel mixture without lubricant will rather quickly disable the engine, which will not be lubricated properly.
Gasoline and oil form the necessary environment, which reduces detonation, removes unnecessary waste (waste products from the combustion of gasoline products) and protects the inside of the engine from wear.
It is important to remember that when using oil of the wrong classification can happen Breakage or clogging of the motor. Certainly, it will be possible to fix it, but to prevent possible breakages, and to reduce their probability to a minimum, it will be better to study the instruction manual, to know the volume of the two-stroke engine installed on a brushcutter, and to use only gasoline and oil, which will be according to all parameters suitable for this model.
Quite often, in the recommendations section (and sometimes on the label), the manufacturer specifies the partner companies whose gasoline and oil he recommends to fill his models. Most often, the fuel and lubricant recommended by the manufacturer will suit the grass trimmer best.
First of all, it is necessary to immediately exclude from the list of actively used lubricants all oils of unknown (garage, basement) origin. Usually it is not easy to dilute such oils because of the unclear basis, composition.
As a rule, the labels of nonbranded producers do not contain a lot of information, covering only general information, without specifying. It is highly discouraged to dilute and dilute oils such as AC-10 and ACZp-10.
The origin of these lubricants is usually quite vague, it is better to give preference to the proven brands that are used by thousands of people around the country every day.
The distinctive feature of all oils for two-cycle engines is the fact that manufacturers paint them in a color contrasting with gasoline. The fluid is translucent, viscous in consistency, slightly yellowish, but not thick. Usually, we are talking about three colors. red, green and blue.
Do not forget that the color scheme has no impact on the classification (as is often the case with antifreeze).
Under no circumstances should you use oils from a line not designed for grass trimmer. This can have an extremely negative effect on the operation of the power unit, lead to increased fuel consumption, soot on the plugs and a number of other problems that will have to be identified and eliminated.
Oil for brushcuts. how to choose, in what proportions to dilute
Many of you have gasoline-powered tools in the household, for example, in a private home can not do without a chainsaw. You know, making firewood for the winter, comes in handy at construction and repair, and in general, it’s a very necessary tool. If a country house has another and a decent-sized plot, then to fight the grass just need a trimmer for grass or lawn mower, which also work on gasoline.
Sure, you can buy electric ones, but not everyone likes to pull a 30-meter extension cord to mow an area overgrown with knee-high grass. That’s why most people prefer to work with a gasoline-powered tool. As you know, you need to add a special oil for two-stroke engines to the gasoline. Here we will talk about it, because it is a very important aspect, if you do not add oil and add in wrong proportions, then your engine will fail very quickly and your way will be to the service center. To avoid all these troubles, you should add only quality oil in right proportions.
The most popular solution for chain saws, brush cutters and trimmers is the well-known STIHL brand. It comes in two packages. 1 liter and 100 ml. A liter bottle is enough for those who works a lot and a small bottle is enough for “one cut”. The capacity of 1 liter costs 250, and 10 ml. 60. If you use a bigger one, it saves a lot of money.
You add oil to petrol in the ratio of 1 to 50, so for example you add 100 ml for 5 liters of petrol. As you can see, a small bottle is perfect for getting 5 liters of gasoline mixture to fill a chainsaw or grass trimmer. The big bottle has special markings on the side so you can tell how much oil you’ve emptied from the bottle. If you bought a big 1 liter bottle, buy a 20ml syringe at the drugstore. Very convenient. 1 syringe of oil for 1 liter of petrol.
Honda GX35 & GX25 Trimmer, VersAttach, and VersaTool Oil Change
We advise you to use original STIHL oil for your machine because it’s been developed and tested specifically for STIHL power tools. I should note that Stihl has its own brands, such as VIKING (popular models of gasoline trimmers). Use Stihl oil for them as well and you won’t have any problems at all.
If you put more gasoline mixture than you can use, it’s best to store the rest in a metal canister or glass container. Never keep the mixture in a plastic bottle. Of course, if you use up the rest in a couple of days, you can pour the rest of the mixture and in a plastic container, but if the mixture will be stored for a long time, then either a canister or glass containers. The thing is that the gasoline mixture corrodes the plastic bottle, microscopic sediments of plastic appear in the mixture, and it is very bad for the engine. Keep this in mind if you want your tool to run long and trouble-free.
The second most popular brand of oil is the unbeknownst Hooksvarna. Of course, if I think about it that way, more people use STIHL chainsaws, at least all my friends and their friends use them only in their work.
However, there are those who cherish Husqvarna tools and I understand them, because I personally do not see much difference between Husqvarna and Stihl, both tools are of very high quality. But I have seen satisfied Husqvarna chain saw owners. they say the saws are great. I haven’t cut any saws myself but I always listen to what people have to say. So, if you have a gasoline tool Husqvarna, it will be better to use a special brand oil for it. Although nothing terrible will happen if you dilute the gasoline Stihl. But since the manufacturer recommends only using its products, this is what we do
On sale you can find a liter containers. The bottle is black and has style marks on the side, the same as Stil’s (to know how much oil has been poured out of the bottle). Seems to me the quality is exactly the same. It’s a 270 bottle, a little more expensive.
The two oils are of high quality, cost about the same, each diluted at a ratio of 1 to 50. So feel free to buy any oil, of course, better to take the brand of oil that you have a tool. then everything will be perfect, just as the manufacturer advises. Good luck with sawing, mowing the grass and let your power tool work for a long time without failures.
Rules of mixing
For the preparation of the fuel mixture you should use a clean and dry container, which does not contain any foreign particles or impurities. It is not recommended to use plastic containers. After you have added the liquids in the proper proportions, you must mix the mixture thoroughly for 2 to 3 minutes. Do not do the following:
- Add a small amount of oil directly into the gas tank of the trimmer, as this will not give a homogeneous mixture;
- Pour oil first, then gasoline. Because of the difference in density, this order of adding components also results in a non-uniform mixture4
- Metering by eye. With this approach to achieve the exact proportion of gasoline and oil for grass trimmer 1/50 or 1/40 is not possible;
- Use polyethylene bottles because the latter dissolves with gasoline.

How to Dilute Gasoline with Oil for Grass Trimmer?
Grass trimmer specifications contain references to recommended fuels and lubricants. How to properly dilute gasoline with oil for a lawnmower, what gasoline for a grass trimmer?
And the octane number of gasoline brand is specified specifically, but when it comes to oils, there is a broad explanation of the need to use a certain manufacturer’s product.
For the sake of reassurance it is pointed out that only when these tips are followed, the company extends the warranty. What is it: an advertising trick or oils from other manufacturers do not meet the requirements? The answer is in the true article.
Why mix grass trimmer oil with gasoline
The two-stroke engine has an ordinary and at the same time very efficient design:
- the piston makes a working stroke every 2nd stroke;
- The cylinder lubrication is done with oil dissolved in gasoline;
- the exhaust of the combustion products is done by compression, without a special mechanism.
All this determined the creation of a family of small engines, successfully adapted in household and professional equipment:
Due to the design features, it was only possible to achieve the desired fuel consumption on small engines with a capacity in the range of 15. 20 liters.forces. How do I properly dilute the gasoline and oil for the gasoline mower if I don’t mix the gasoline with. This indicator looks particularly good in the range of 1. 5 L.с. Here the engine is completely low in weight and size corresponds to the gasoline consumption.
As the size increases the area of the inlet and outlet ducts. The process of gas extraction and fuel supply is sharply improved. That’s why it was necessary to switch to a more efficient system for burning gasoline consistency, which would include the presence of forced maintenance of the engine.
Four-stroke models by this intercepted the palm tree among the power units of the highest capacity. Combining them into a multi-cylinder design allowed the creation of special systems related to the formation of the composition of fuel consistency, lubrication and other things that favorably affected gasoline consumption.

How to dilute gasoline (AI 92) for grass trimmers and lawn mowers.
The friction parts of the piston and cylinder of a two-stroke motor are lubricated by oil in a certain proportion of the fuel. Gasoline burns and oil settles on the surface of the cylinder, reducing friction of the rubbing parts.
Lack of lubrication leads to cylinder damage, up to jamming. In the case of an overabundance, under the influence of high temperatures, there is a deposition of thermally modified product in the annular grooves.
The compression drops and so does the power.
How to Mix Oil with Gasoline
Motor oils are used to add to gasoline for grass trimmer. How to properly dilute gasoline with oil before filling a lawn mower. Mixing is done in a certain proportion. Manufacturers have different volume ratio: from 1 to 50 to 1 to 20.
Practical tips on how to dilute gasoline with oil properly. But, as. There is a reference to this in the technical specifications. How to dilute petrol with oil for grass trimmer? You should be careful with a small proportion of oils.
A slight inaccuracy leads to oil starvation of the engine, reducing its life.
There are products, which specify the proportion of 1 to 20-40. Practical tips on how to dilute gasoline and grass trimmer oil. Can be attributed which. It is better to refuse using such lubricant. A wide range of the mixture indicates the low quality of the product. Piston ring lodging, with the constant use of such grades, is practically guaranteed.
M-8 type engine oils are added in the ratio of 1 to 20. In high-speed engines, their use is undesirable. The cycle between feeding the mixture is so small that it will cause an overabundance of lubricant in the cylinder.
Grass trimmers have low revolutions and therefore allow the use of low-grade grease. Peculiarities of fuel for two-stroke engines and classification of oils. Practical hints on how to dilute gasoline and grass trimmer oil.
Due to the inherently low service life, you do not have to worry about ring coking. Before the full wear and tear of the equipment.
The principle is not to use the recommended oil or oil from other manufacturers. The main thing is to dilute gasoline with grass trimmer oil in proportions according to the characteristics of the product. It is illegal for service shops to deny warranty solely on the basis of using a different brand of oil but with acceptable parameters.
How much oil to add to gasoline?
Types of oils used to dilute in gasoline
There are no oil pumps in chainsaws, so it is impossible to use only a combustible mixture. Carefully read the manufacturer’s instructions included with each product. There is a lot of information on the Internet, which is not very difficult to find.
If you don’t use any lubricant, the saw will break down in a short time. It is recommended to do preventive maintenance of the unit, pour properly diluted fuel, in this case the tool will function for many years.
Carefully read the manufacturer’s instructions. “It always states in detail which lubricant is required by the power tool. You should not save on oil, the benefit is small, but the engine life can be significantly reduced. Tool repair is expensive, up to 85% of its cost.
If you take, for example, chain saw “Husqvarna”, then unleaded gasoline with the first additive of mark 92 is suitable. If the composition has a greenish tint, it indicates that the product is a “Premium” class. AI-92 is the optimal product that can be suitable for such a device. On average, professionals advise to add from twenty to fifty ml of machine oil per liter. If the power of the machine is one and a half kilowatt, then only 25-27 ml of oil will be required.
Opinion of the expert Kuznetsov Vasily Stepanovich
If the tool is more powerful, you need about 30 ml of oil, and in some cases even more.
How to dilute machine oil and gasoline, in what proportions? This question arises with all users. To begin with, you should stock up on containers:
The process of mixing oil and gasoline is technologically simple
It is important to observe safety precautions, so that no static electricity is accumulated, not a drop of water gets into the fuel
Types of oils used for dilution in gasoline
What proportions should be done? Engines are mostly two-stroke, so the mixture is usually 1:50. Russian-made chainsaws function with products of these brands:
For foreign counterparts allowed to use two liters of gasoline per 80 grams of oil. Foreign saws are economical, the proportions of oil in them vary from 40 to 49 fractions.
The shades of oil can vary significantly, it should be taken into account during operation. For example HP company produces machine oil with reddish tint. If the composition has a greenish (sometimes blue) tint, it is a sure sign that the product is a premium synthetic. The quality of such compositions is high and their price is also not trivial.
For trimmers, a special two-stroke oil is produced, which should be marked “2T” on the package. It is strictly forbidden to use motor oil, especially transmission oil. Two-stroke oil is produced in three kinds:
It all depends on what substances make up the oil base. Mineral oil is the cheapest and unreliable. Its use is justified only in domestic trimmers, which work for 30-60 minutes a day with long breaks. Most brushcutter manufacturers at this level indicate that TC-W3 oil is the correct engine oil. This means that mineral, synthetic, and semi-synthetic 2T oils can be used.
For professional-grade brushcutters, it is advisable to buy only the oil brands recommended by the manufacturer. Usually it is semi-synthetic and synthetic with special additives. Manufacturers mark the oil with letters:
- TA for two-stroke engines up to 50 cubic centimeters;
- TV for engines up to 50 to 200 cc;
- TC for motorcycle engines, snowmobile engines, etc.д.
All three versions of oil can be used in brushcutters, if the oil type is not mentioned in the manual. How much oil to add to the fuel of grass trimmer depends on the brand of tool and the quality of gasoline. Also there may be letters FA, FB, FC, etc. on the oil package.д. These indicate the level of smokiness. The closer the second letter is to the beginning of the alphabet, the more smoke is emitted during combustion. As a rule, quality oil has very little. Oil selection is not influenced by this parameter. important than “self mix” and “pre mix”. The first word means that the oil dissolves itself, and the container with the second mixture must be shaken several times. The best oils on the market are STIHL, Shell Helix Ultra, Oleo-Mac, Lukoil.
Choosing the right oil for your chain saw
Two-stroke engines are fueled with a mixture of unleaded gasoline and oil marked 2T. You need to use recommended gasoline AI-92. If a higher octane rating is used, the flash and combustion temperature will be higher, and the valves will burn prematurely. The same applies to oil. The recommended composition is not the most expensive. But you can’t use any other brand. Viscosity will change, resulting in inadequate lubrication of conventional products made without precision lapping.
If too much oil is added, incomplete combustion will result in fouling and excessive exhaust emissions. A rich mixture is bad for your engine. For four-stroke engines, add oil separately from petrol. It washes the nodes, cools, reduces friction The oil gets contaminated during operation and must be changed after 50 operating hours. You can read the oil type in the machine’s data sheet. The compound should be marked 4T with a viscosity 10W40.
The best oil for every engine is the recommended oil. But Shel Helix Ultra is the world’s best-known oil. For 40 years the company has been developing a new technology to produce synthetic oil from natural gas. Pureplus technology has made it possible to get an improved base oil composition. The leading oil companies use it as a basis, adding the correct additives, to produce the oils recommended by the leading oil companies for their equipment.

The choice of oil depends primarily on the manufacturer’s recommendations. For example, STIHL lawnmower oil is used only from STIHL. The same oil is good for the brand Vityaz, as the engines in the brands of the same brand. There is an opinion of experts, the oil of any manufacturer intended for one type of equipment is suitable for all brands. But if there is a possibility, it is better to use the recommended one.
Oil should be stocked as needed for one season. Product that has been sitting for a long time loses its properties. On sale is available in packages from 0.1 to 5 liters.
Investigated the path of the oil recommended for Husqvarna lawnmowers. The company does not have its own production, only a bottling plant. The product you buy in bulk is filled into small containers, labeled and shipped to the stores. Possibly exclusive Husqvarna additives were added to the oil at the time of manufacture.
It is compulsory to use oil in accordance with the instruction manual for your brushcutter. The machine can’t run on pure gasoline.
