How much oil to pour into the trimmer for grass per liter of gasoline
Gasoline mowers. quite common tools used by garden and homestead owners for mowing grass and making hay. common names of tools are the terms “grass trimmer” and “lawnmower”. The main difference is hidden in the design of the motor. the expensive segment of the devices is equipped with four-stroke models, and the cheap ones. two-stroke. The latter option has advantages, including a small weight, ease of use, as well as a low cost.
The most important condition for two-stroke models is the preparation of the fuel mixture, based on the manufacturer’s defined proportion of gasoline and oil. The simplified design of the engine does not provide a separate channel for lubrication, so engine oil is added directly to the gasoline. Violation of the correct proportions leads to a significant reduction in the resource of the tool and even to its failure. Let’s understand what composition is required for gasoline trimmers, how to properly prepare the mixture and what it can affect.
Choice of gasoline for grass trimmer
For some reason everyone prefers to choose a brand of gasoline for brushcutter at his discretion. This is an erroneous approach, because, first of all, you need to carefully study the instructions, where the manufacturer’s recommendations on the selection of the type of fuel are given. But this is also not a guarantee, because unleaded fuel can be sold under different brands (which differ in many manufacturers), with significantly different composition. Therefore, it is necessary to be guided by the main characteristics in order to choose gasoline for a particular model of trimmer for grass.
Petrol tool manufacturers recommend using gasoline brand AI-92 to work, but for more expensive types will need fuel with a higher octane number. AI-95. Any brand that has the number 90 or less in its label is not suitable for benzocos as it leads to rapid wear and tear. The problem results from unscrupulous fuel producers who sell a totally different brand under the guise of 92. The situation is as follows:
- In the passport on the gasoline equipment there is a recommendation to use gasoline with an octane number not lower than 92;
- The conscientious owner goes to the gas station where the price is lowest and with a clear conscience fills the brushcutter with such fuel;
- As a result, the service life is reduced, because it is often sold under the guise of AI-92 AI-80 and AI-76.
To avoid such a situation, you need to choose a filling station, which sells proven gasoline (it can be determined by the testimonials of regular customers). It is also important where to pour fuel after purchase. only metal containers should be used (plastic is prohibited).
Preferably, when there is an opportunity to buy gasoline for grass trimmer high purity specifically for garden equipment. You can be sure of its quality and anti-counterfeit protection.
How to buy a brushcutter
Now on liquid profile commercial sites a wide range of devices for mowing grass, small bushes. For example, there are lawn trimmers with an electronic engine, with gasoline-powered counterparts. Diesel-engine brushcutters are NOT produced, because they have a low revolution speed.
Liquid statistics show the advantage of brushcutters with internal combustion engines over their electronic counterparts. Electric brushcutter is used in places where there is a stationary electronic network.
The mix of gasoline and oil you choose for your brushcutter must meet the necessary requirements specified in the manual. It is important to note that domestic manufacturers often label their products slightly differently than the American or Japanese classifications. Russian producers of lubricants, as a rule, put the 2T designation on all oils intended for two-stroke engines. It is not uncommon to find oil cans on the shelves of stores that have o or “pre mix” on them. In the first case, it 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, accordingly, 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 explained by the fact that the fuel mixture without lubricant pretty quickly puts out of operation the internal combustion engine, which will not be lubricated properly. Gasoline and oil create the necessary environment which reduces detonation, removes unnecessary waste (waste products from gasoline combustion) and protects the inside of the engine from wear.
It is important to remember that using oil of the wrong classification can cause engine damage or clogging. Of course, it can be repaired, but in order to prevent possible breakdowns, and to reduce their probability to a minimum, it will be better to study the instruction manual, learn the volume of the two-stroke engine installed on the brushcutter, and use only gasoline and oil, which will fit all the parameters of this model.
Quite often in the recommendations section (and sometimes on the label), the manufacturer specifies the partner companies whose gasoline and oil it recommends to fill its models. Most often, the fuel and lubricant recommended by the manufacturer will suit the grass trimmer best.
First of all, you should immediately exclude from the list of actively used lubricants all oils of unknown (garage, basement) origin. It is usually not easy to dilute such oils, because of the obscure base, composition. As a rule, the labels of non-branded manufacturers do not abound with information, covering only general information, without clarification. It is highly discouraged to dilute and dilute oils such as AC-10 and ACZp-10. The origin of these lubricants is usually quite obscure, it is better to give preference to proven brands that thousands of people across the country use every day.
A distinctive feature of all oils for two-stroke 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. It usually comes in three colors. red, green and blue.
Do not forget that the color scheme has no effect on the classification (as is often the case with antifreeze).
Never use oils from a line not designed for grass trimmer. This can have a very negative effect on the operation of the power unit, leading to increased fuel consumption, fouling of the spark plugs and a whole range 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 help.
If the purchased liquid does not have the declared qualities (for example, too liquid), in no case you should not mix it with gasoline. The best way is to return the oil to the store, explaining the return reason to the dealer.
Peculiarities of filling of brushcutters
Depending on the engine arrangement, brushcutters are divided into two-stroke and four-stroke brushcutters. In the first case, the piston in the internal combustion engine makes 2 strokes per working cycle, and in the second case. 4 strokes. Differences in the principle of the engine and cause different approaches to refueling trimmer for grass.
Fueling a brushcutter with a two-stroke engine
In common household models of brushcutters, as a rule, a two-stroke engine is used. The lawnmower does not need a lot of power and manoeuvrability. It is therefore well suited for the task at hand. In addition, this engine is much cheaper and easier, but it is fueled by a fuel mixture that consists of oil and gasoline. This fuel is filled into the carburetor and fed to the cylinder in the form of a petrol-oil mist. The oil thus lubricates all necessary parts and is burned together with the gasoline during engine operation. However, the combustion of this mixture is accompanied by emission of acrid odor and smoke, which increases the toxicity of exhaust gases.
Important! For these brushcutters, you need to use special oil for two-stroke engines, which burns completely, without leaving a burnout, and has low evaporation. The oil must be a solvent of 20% to mix well with petrol.
Filling up brushcutters with four-stroke engines
Four-stroke engines are used in professional brushcutter models. These brushcutters have plenty of power and can run for a long time without stopping and refuelling. They also use gasoline and oil, but fill different tanks. This means that oil is not part of the combustion process, so the exhaust fumes are not as toxic.
Also nota bene! In addition to better environmental performance and less heat, four-stroke brushcutter engines are also more economical. They use much less fuel. savings up to 50 percent for gasoline and up to 80 percent for oil.

The gasoline-oil mix you choose for your brushcutter must comply with the specified requirements. It is important to note that domestic manufacturers often label their products slightly differently, not as accepted by the American or Japanese classification. Russian producers of lubricants, as a rule, put the 2T marking on all oils intended for two-stroke engines. It is not rare to find oil cans marked “self mix” or “pre mix” on the shelves. 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 the mixing will occur without human intervention. In the second case, respectively, it is necessary to shake or shake the mixture to bring it to the desired consistency.

Quite often in the recommendation section (and sometimes on the label) the manufacturer will indicate a partner company whose gasoline and oil he recommends to fill his models. In most cases, fuel and lubricant recommended by the manufacturer are best suited for 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 the unclear basis, composition. As a rule, the labels of unbranded manufacturers are not rich in information, covering only general information, without specifying. It is strongly not recommended to dilute and dilute such oils as AC-10 and ACZp-10. The origin of these lubricants is usually quite obscure, it is better to give preference to the proven brands that thousands of people across the country use every day.

It means that you have to replace the defective parts at your own expense, and no exceptions will help you.
If the fluid you have purchased is not of the quality you claim (for instance, it is too thin), you should never mix it with gasoline. The best way is to return such oil back to the store, explaining to the seller the reason for the return.

How to properly pour ready fuel into a two-stroke motor
Many people do not follow some important recommendations for pouring fuel into the gas tank of a grass trimmer or lawnmower, which eventually leads to unpleasant consequences. Let’s look at important recommendations on how to correctly pour diluted gasoline and oil into the gas tank of a brushcutter:
- Prepare a funnel or watering can. Despite the large diameter of the gas tank opening, very often when you try to get into it, some of the fuel will spill and end up on the body of the tool. Fuel that has been spilled on the tool can ignite when heated, so it is important to use a funnel or watering can
- Before unscrewing the cap, the surface of the tank should be thoroughly cleaned as dirt can get inside and cause the gasoline filter to clog quickly
- You should refuel in calm weather or in a sheltered place to avoid dust and small grains of sand from getting inside the tank
- Do not leave the fuel tank hatch open for a long time, because not only small grains of sand and dust, but also insects can get into it
- Do not inhale petrol vapours when filling up, as they are dangerous to humans. When working with a trimmer, the master must use protective goggles, headphones and a respirator
- The fuel should be filled to the level shown on the fuel filler cap. If you fill up the tank, when you screw in the cap, some of it will come out. not economical use of fuel. In this case, it is better to underfill than overfill
Given these recommendations, you can significantly extend the life of the gasoline tool in question.
This is interesting!Works on mixing and pouring fuel are also recommended to be done with protective gloves.
How to choose an oil
Depending on the chemical composition, there are different types of engine oils:
- mineral. made from petroleum distillates and designed for low-powered equipment with air cooling;
- semi-synthetic. is a mixture of mineral and synthetic oils and is suitable for 2T and 4T, as well as for air and liquid cooling;
- Synthetic. produced on the basis of esters and may be used in heavy-duty equipment, and also for operation in severe climatic conditions.
Important! Oils for two-stroke and four-stroke engines differ in their ability to dissolve, burn and evaporate. To distinguish the liquid lubricant from gasoline, it is painted in different colors: blue, green, red.
Depending on the classification of API we can distinguish the following groups of oils for trimmer motors:
- TA. for low-power machinery with engine displacement up to 50 cm³ and air cooling;
- TV. for powerful equipment with engine displacement of 50-200 cm³ and air cooling system;
- TS. for powerful two-stroke equipment (brushcutters, chainsaws, lawn-mowers, etc.).) with engine capacity of 50-200 cm³;
- TD. for boat engines with liquid cooling.
To choose the right oil for your particular model of grass trimmer, it is best to take into account the recommendations in the manual. For brushcutters 2T oil is usually used class API-TV and API-TS.
For your information! In addition, for two-stroke engines there is the JASO classification, and for four-stroke engines still use SAE30.
The leading companies-manufacturers of garden equipment themselves develop and produce oils for their equipment. Such lubricant compositions best meet all the technical and operational characteristics of specific trimmer series. For example, for STIHL brushcutters (STIHL) FS 5 the oil type STIHL HP or STIHL HP SUPER is the best; for Husqvarna 143R the oil type is Husqvarna HP or Husqvarna LS. But for Patriot brand oil will do and usual mineral oil M-8B.

Depending on the API classification the following groups of oils for trimmer motors can be distinguished:
- TA. for low-power machinery with engine displacement up to 50 cm³ and air cooling;
- TV. for high-powered equipment with engine displacement of 50-200 cm³ and air cooling system;
- TC. for powerful two-stroke equipment (brushcutters, chainsaws, lawnmowers, etc.).) with engine displacement 50-200 cm³;
- TD. for liquid-cooled boat engines.
Choosing the right oil for your grass trimmer is best done according to the recommendations in the owner’s manual. API-TV and API-TC oils are commonly used for 2T brushcutters.
For your information! There is also a JASO classification for two-stroke engines, and SAE30 is used for four-stroke engines.
The leading gardening equipment companies develop and produce their own oils for their machines. These lubricants best meet all the technical and performance specifications of specific trimmer series. For example, the STIHL FS 5 brushcutters (STIHL) are best fitted with STIHL HP or STIHL HP SUPER oil, and the Husqvarna 143R is suited to Husqvarna HP or Husqvarna LS oil. But for Patriot brand will suit and ordinary mineral oil M-8B.
What kind of oil to choose for your grass trimmer or types of lubricants
Grass trimmers and lawn mowers are powered by two-stroke engines that have a simplified design. Rarely, but there are trimmer models with 4-stroke engines that run on pure gasoline. Two-stroke power units have no engine oil compartment (oil sump), which reduces the weight of the tool and its cost. If the rotating parts of the motor will not be lubricated, then as a result they will quickly fail. To prevent this, the grass trimmer is not filled with pure gasoline, but with a mixture of oil. What oil to dilute with gasoline for grass trimmer?
To begin with, let’s remember or find out what types of oils by chemical composition are produced:
- Mineral fluids. designed for low-power, air-cooled machines. This is the cheapest type of engine lubricant
- Semi-synthetic substances. they are used for equipment that has air and water cooling
- Synthetics. suitable for all engine types with different types of cooling. They don’t require frequent changes, and this type of lubricant is several times more expensive than mineral and semi-synthetic
From the above it follows that the grass trimmer is suitable for any oil composition. mineral, synthetic and semi-synthetic. Oils with different chemical compositions differ in price, so when buying should be based on the recommendations of the tool manufacturer. The instructions contain recommended information on what types of oils are best to use. If it is TC-W3, then chemical composition is not so important. In this case, you can dilute mineral, semi-synthetic and synthetic with gasoline.
This is interesting!The main thing when choosing oil do not get caught on the fake, as today very often you can meet different types of lubricating compositions for two-stroke motors, which consist mainly of low-quality petroleum products.
It remains to choose which gasoline to fill in the trimmer for grass. The choice is not great. AI-92 and AI-95. The difference between them is quite substantial. If the manufacturer’s instructions do not specify what gasoline to use, you must stop at AI-92. It almost does not depend on the brand of gasoline, how much oil to add per liter of gasoline, if the fuel is of high quality and fully complies with the declared brand. Buy gasoline only at branded gas stations, where the risk of buying A-80 instead of AI-92 is almost zero.
If it is recommended to fill Ai-95, do not use other brands of gasoline. If the engine starts, it will run irregularly and quickly overheat. So you risk to put out of operation the motor not only domestic trimmer for grass, but also professional.
We learn how to dilute petrol with oil for grass trimmer if you under or overfill the oil
If you bought a grass trimmer, lawnmower, brush cutter, chainsaw and other types of equipment, you probably know that two-stroke motors are used as power units on them. These motors do not run on pure gasoline, like four-stroke motors, but on a mixture of gasoline and oil. How much gasoline and oil should be diluted for grass trimmer. this is the question every dacha owner asks himself before preparing the tool for work. Let’s understand this issue in detail, as the dilution of gasoline with oil for grass trimmer affects the service life of the tool, and improper preparation of the mixture, will lead to rapid engine wear. What are the dangers of excessive or insufficient amounts of oil in gasoline for grass trimmer:
- If the gasoline will be diluted with a lot of oil (above the norm), it will lead not only to a large amount of smoke, but also to the formation of soot on the cylinder walls and a drop in power.This fouling will cause wear of the piston, which will be diagnosed by a decrease in its performance
- If the gasoline does not contain enough oil in the grass trimmer, it is even more dangerous.After all working mechanisms of the engine will not be lubricated in sufficient quantity that will result in their fast wear and tear (there is a fast destruction of piston rings and engine jamming). If the amount of oil in the gasoline poured into the grass trimmer is insufficient, the wear of the motor will occur dozens of times faster
To avoid having to pay for mistakes at the price of an engine overhaul or the purchase of a new tool, you need to fill the tank with fuel of the correct consistency from the first day. You can find out the ratio in the instructions to the tool, because the models of different manufacturers may give different recommendations. Usually this ratio is the following norms:
- 1:25 or 40 grams of 2-stroke oil per liter of gasoline
- 1 to 40, or 25-30 grams of oil for 1 liter of gasoline
- 1 to 50. this is 20 grams of oil added to a liter of gasoline
The standard value is 1:50 (indicated on canisters of oil for two-stroke engines), but it should be relied on as a last resort, as manufacturers indicate the recommended value of the proportion, and if not respected, it reduces the operational life of the two-stroke engine.
In addition to following the recommended proportions, you must also learn how to prepare the mix. After all, the option of adding oil to the gas tank, is categorically contraindicated, although some do so. If you have bought a grass trimmer or lawn mower, you will need the consumables you will use to prepare the mixture. The instructions for preparing the fuel mixture in the grass trimmer are as follows:
- Prepare gasoline and two-stroke oil, based on the above recommendations for the choice of lubricant and fuel
- In addition for the preparation of the mixture you need to take a container or container. Usually a plastic bottle is used for this purpose, which you need to choose accordingly. It has to be clean inside. It is not recommended to use a container from under milk, beer or other drinks. A mineral water container is optimal
- It is very important that the container had a whole value of volume, that is, 1 or 2 liters, so that you do not have to calculate how much to pour oil in a bottle of 1.5 liters, 1.3 or 1.25 liters, because so you can easily make a mistake
- You will also need a syringe, which is used as a measuring device for dosing the oil. For such purposes, an ordinary medical syringe of 10cc or more is suitable. It is desirable that the syringe has an accurate measuring scale
- After preparing the necessary materials, you can proceed to the preparation
Instructions for preparing the fuel mixture into the lawnmower:
To begin with, you should fill a plastic container. The container is filled to 2 fingers not full, so that the oil will fit
After preparing the fuel mixture for the grass trimmer, it remains to fill up the tool, and start working. How to properly fuel grass trimmers, lawnmowers, chainsaws and other types of motor equipment, let’s consider in detail.
ДOnly fresh gasoline is used to dilute and apply to the trimmer.
Oil for brushcutters. how to choose, in what proportions dilute
Many of you have power tools in your household, for example, in a private home, you can’t do without a chainsaw. You know, making firewood for the winter, comes in handy at construction and repair, and in general, it is a very necessary tool. If your country house also has a decent-sized plot, then the grass trimmer or lawn mower, which also run on gasoline, is simply necessary to deal with grass.
Of course you can buy electric as well, but not everyone likes to pull a 30-meter extension cord to mow a knee-deep patch of grass. That’s why most people prefer to work with petrol tools. As you know, you need to add a special oil for two-stroke engines to gasoline. Here we are going to talk about it, because this is a very important aspect, if you do not add oil and add in the wrong proportions, then your engine very quickly “will fail” and your way will lie in the service center. To avoid all these troubles, add only quality oil and in the right proportions.
The most popular for chain saws, brush cutters and trimmers are products of the famous STIHL company. It comes in two packs. 1 liter and 100 ml. For those who work a lot, a liter bottle is enough, but a small bottle is enough to “once cut”. A 1 liter bottle costs 250, and a 10 ml bottle costs 60. If you take the big one, the savings are obvious.
The oil is added to gasoline in the ratio of 1 to 50, that is, for example, for 5 liters of gasoline add 100 ml. As you can see, a small bottle is great for getting 5 liters of gasoline mixture for your chain saw or weed trimmer. There are special marks on the side of a big bottle, by which you can see how much oil you have poured out of the bottle. If you bought a big 1 liter bottle, buy a 20ml syringe at the drugstore. It is very convenient to add 1 syringe of oil to 1 liter of petrol.
It’s the experts’ recommendation to use a brand-name oil for your machine. it’s perfect, because it’s been developed and tested specifically for STIHL power tools. Note that Stihl has its own brands, such as VIKING (popular models of gasoline trimmers). Use Stihl oil for them as well and there will be no problems at all.
If you put more gasoline mixture than you can use, it is best to store the leftovers in a metal canister or in a glass container. Never store petrol mix in a plastic bottle. Of course, if you use up the leftovers in a couple of days, you can pour the rest of the mixture into a plastic container, but if the mixture will be stored for a long time, then either a canister or a glass container. The thing is that the gas mixture corrodes the plastic bottle, there are microscopic precipitations of plastic in the mixture and this is very bad for the engine. Keep this in mind if you want your tool to run long and without problems.
The second most popular oil brand is notorious Hooksvarna. Of course, when you think about it that way, more people use STIHL chain saws, at least all my friends and their friends use them for work only.
But there are some who dote on 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’ve seen some happy Husqvarna chain saw owners. they say the saws are great. I haven’t done it myself, but I always listen to what people have to say. So, if you have gasoline Husqvarna tool, then 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 to use only its products, we are going to do so.
On sale you can find a liter capacity. Black stylish bottle, with the same markings on the side as Stihl’s (to know how much oil has been poured out of the bottle). Seems to me the quality is absolutely identical. It costs 270, a little bit more.
Both oils are of high quality, the cost is about the same, each diluted in the proportion 1 to 50. So feel free to buy any oil, of course, it is better to take the oil of the brand that you have a tool. then everything will be perfect, just like the manufacturer advises. Good luck with cutting and mowing, and may your power tool work for a long time without downtime.

Types of engine oils and their function
Choice of oil for a gasoline trimmer
Engine oil for gasoline grass trimmer is a lubricant that serves to reduce wear and tear between the rubbing parts of the engine.
The oil composition includes residual hydrocarbons and various additives that improve the properties of the final product. To ensure the long and trouble-free work of the lawnmower, experts recommend using oil, which by its physical and chemical properties correspond to this type of motor.
Today it is customary to distinguish between three basic types of oil according to the way they are made:
- Mineral, created in the process of distillation of hydrocarbons;
- Synthetic oils obtained by processing natural gas or by synthesis;
- Semi-synthetic, which includes an improved mineral oil with the addition of some synthetic components.
In order to prevent the mixing of different types, the manufacturer adds a dye to the oils, which shows the difference in the composition of the lubricant.
What oils for trimmers should be used
In order for the grass trimmer to serve faithfully for a long time, it is necessary to take a serious approach to its maintenance. One of the important aspects of grass trimmer maintenance is the choice of engine oil.
Grass trimmers have become indispensable helpers in many household plots. They can function as a complete set of hand-held garden tools, used for cutting grass, trimming bushes or trees, and even for shoveling snow. Modern mechanisms are characterized by reliability and long service life, which also depends on the use of the right type of oil. Owners of gasoline saws and similar units will not have difficulties with the maintenance of the grass trimmer: the oil used for most is the same.
For two-stroke engines
Most trimmers have a two-stroke engine, which, although it has the simplest device, still requires close attention during maintenance. For filling two-stroke engines, a mixture of gasoline and oil in a certain proportion is used. It is this ratio that plays a decisive role. It must be specified when buying a grass trimmer. When it comes to oil, just about any lubricant that is marked 2T is suitable. Of course, the manufacturers of expensive tools require the use of fuel and lubricants to a specific specification, but for most trimmers are suitable oil such as Mobil 2T, Liqui Moly Motorrad 2T or Castrol Power1 Racing. Medium oil additive. about 20 g per 1 liter, but over time, the amount of lubrication can be determined experimentally by the presence of soot on the plug and the degree of contamination of the carburetor.
Four-stroke engines have a separate oil reservoir. Such power units are more sensitive to oil quality than two-stroke engines, although special problems with maintenance of trimmers with a four-stroke engine should not arise. Mannol Quad or ZIC 4T are good for inexpensive trimmers. For trimmers that are more than three years old, an oil with cleaning and degreasing additives is recommended. In this case you can use XADO Atomic Oil 4T oil, which has a whole complex of additives and is characterized by higher viscosity. 10W60. In most cases semi-synthetic oils of medium viscosity 10W40 in the medium price range are suitable for trimmers.
