What oil to add to petrol for grass trimmer
Grass trimmer specifications contain references to recommended fuels and lubricants. In this case, the octane number of gasoline is specified specifically, but in terms of oils is a broad explanation of the need to use a product of a particular manufacturer. How much oil and gasoline to dilute for 1 liter of grass trimmer. to make sure it is specified that only when complying with these instructions does the company provide a warranty. What is this: an advertising ploy or other manufacturers’ oils do not meet the requirements? The answer is in the actual article.
Why mix grass trimmer oil with gasoline
Two-stroke engine has an ordinary and, at the same time, very effective design:
- the piston makes a stroke every 2nd stroke;
- cylinder lubrication is done with oil dissolved in gasoline;
- the exhaust of the combustion products is effected 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 peculiarities of design, the desired fuel consumption could only be achieved in small engines with capacities in the range of 15. 20 liters.Forces. In particular, this figure looks great in the range from 1 to 5 liters.с. Completely low weight and the size of the motor matches the gasoline consumption.
As the size increases, so does the inlet and outlet area. for 1,2,5 you need 50 ml. Oil (per 1 liter of gasoline you need. The process of removing gases and fuel supply is sharply deteriorated. This necessitated a transition to a more efficient gasoline mixture combustion system that included forced engine maintenance systems. Four-stroke models have taken over the palm of the high-powered machines. Combining them into a multi-cylinder construction allowed the creation of special systems related to the formation of the fuel mixture, lubrication, etc., which favorably affected gasoline consumption.

With oil for grass trimmer and chain saw?
The friction components of the piston and cylinder in a two-stroke engine are lubricated by oil in a particular proportion of the fuel. How much oil 25 ml of oil for one liter of gasoline. If you don’t add oil to fuel, how much oil to put in 1 liter of gasoline in a chainsaw. Diluting gasoline for. Gasoline burns off and oil settles on the surface of the cylinder, reducing friction of the rubbing parts. Lack of lubrication leads to cylinder damage up to and including jamming. In the case of overdosing, due to the high temperatures, the thermally modified product deposits in the annular grooves. Compression goes down, and with it, so does the power.
How to mix oil with petrol
Motor oils are used for adding to petrol for grass trimmer. When switching to another type of oil and gasoline how much oil. Mixing is made in a certain proportion. Manufacturers have different volume ratios: from 1 to 50 to 1 to 20. There is a reference to this in the technical specifications. Care should be taken with a small proportion of oils. Most often it’s 1 to 50 (20 grams of oil per liter of gasoline). How much does the trimmer for grass cost. A slight inaccuracy leads to oil starvation of the engine, reducing its service life.
The mixture of gasoline and oil chosen for the brushcutter must meet the necessary requirements specified in the manual. It is important to note that domestic manufacturers often label their products slightly differently, not as is customary according to the American or Japanese classification. Russian lubricant producers, as a rule, put the 2T logo on all oils for two-stroke engines. It is not rare to find oil cans marked “self mix” or “pre mix” on the shelves of stores. In the first case it means that the oil does not need any additional manipulations, you just pour the gasoline and oil in one container, and mixing will happen without human intervention. In the second case, accordingly, it is necessary to shake or shake the mixture to bring it to the right consistency.
As you can see, there are different classifications of lubricants, indicating that using oil in two-stroke engines is necessary. The reason for this is that a fuel mixture without lubricant fairly quickly puts the engine out of operation, which will not be lubricated properly. Gasoline and oil form the necessary environment that reduces detonation, removes excess debris (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 damage or clogging of the motor. Certainly, it will be possible to repair it, but to prevent possible breakages, and to reduce their probability to a minimum, it will be better to study the instruction manual, find out the volume of the two-stroke engine installed on a brushcutter, and use only petrol and oil, which will suit this model according to all parameters.
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, fuel and lubricant recommended by the manufacturer will work best for the grass trimmer.
First of all, it is necessary to exclude at once 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 base, composition. Generally, the labels of non-branded manufacturers are not very informative, giving only general information without specifying. It is strongly not recommended 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.
How to dilute gasoline with oil fuel mixture for chainsaws and trimmers mineral or synthetic
A distinctive feature of all oils for two-stroke engines is the fact that manufacturers paint them in a color that contrasts with gasoline. The fluid is semi-transparent, viscous in consistency, a little yellowish, but not dense. Usually, we are talking about three colors. red, green and blue.
Do not forget that the color does not affect the classification in any way (as is often the case with antifreeze).
You should never use oils that are not designed for grass trimmers. This can have an extremely negative impact on the operation of the power unit, leading to increased fuel consumption, fouling on the plugs and a variety 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 when you replace the defective parts you have to do it at your own expense, and no exceptions will help.
If the fluid you buy is not what it claims to be (for example, too thin), you should never mix it with gasoline. It is best to return such oil back to the store, explaining to the seller the reason for the return.
What kind of petrol to fill up
Lawnmower gasoline is the second element in the fuel mix. Its brand should be chosen according to the manufacturer’s recommendations, as described in the machine’s data sheet. High octane rating indicates how long the fuel burns and is resistant to detonation. the higher the rating, the longer the fuel burns. For example, you can buy such brands of petroleum products at gas stations:
AI-92 has a higher tendency to detonate.
The mixture is prepared before use in the proportion that is indicated on the gasoline tank cap:
It means that for 1 liter of fuel you need 20 ml of oil liquid.
Manufacturers of gasoline mowers with a two-stroke engine (for example, Patriot PT 555 or Champion T336) specify the required ratio for the preparation of the fuel mixture in the instruction manual of the tool. For the first model, the proposed ratio is 32:1, for the second. 50:1.
Lawnmower with a 4-stroke engine does not require prior preparation of petroleum product. Two reservoirs are provided in the equipment. Gasoline must be poured into the tank, and the oil liquid. in the drainage hole on the crankcase.

Oil. the name is rather relative. It is an oil base with a variety of additives. Without them, its lubricating qualities are not so great.
The base is divided into two types according to the origin:
- Mineral. obtained by petroleum refining. Its properties depend considerably on the composition of the raw material and are not stable, which is why a large number of various additives are added to the mixture. Despite their action, it is recommended to replace the mineral material as often as possible;
- synthetic. obtained by directed synthesis. The properties of the mixture are set in advance, they are characterized by stability. synthetic compounds last longer, they need to be replaced less often.
Additives added to the base, give the ready mixture various additional properties:
- antioxidant. prolong the “life” of the mixture itself;
- Corrosion inhibitors. protects the engine from rusting;
- anti-wear compounds. reduce wear and tear on parts;
- thorny modifiers etc.
Oil for brushcutters. how to choose, in what proportions to dilute
Many of you have in the household petrol tools, for example, in a private home can not do without a chainsaw. You know, making firewood for the winter, it comes in handy for construction and repair, and in general, it is a very useful tool. If the country house also has a decent-sized plot, then to combat the grass just need a trimmer for grass or lawnmower, which also run on gasoline.
Of course, you can buy them and electric, but not everyone likes to pull a 30-meter extension cord to mow the area overgrown with grass to the knee. 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 gasoline. And here we are going to talk about it, because this is a very important aspect, if you don’t add oil and add it in wrong proportions, then your engine will go “croaky” very quickly and your way will be to the service center. To avoid all these troubles, add only quality oil in the correct proportions.
The most popular for chain saws, brush cutters and trimmers are products of famous company STIHL. It comes in two packages. 1 liter and 100 ml. For those who work a lot, a liter bottle is good, but a small bottle is enough for “one cut”. A 1 liter capacity costs 250 and a 10 ml capacity costs 60. If you take the big one, the economy is obvious.
The oil is added to petrol in the ratio of 1 to 50, that is, for example, for 5 liters of petrol you add 100 ml. As you can see, the small bottle is perfect for getting 5 liters of gasoline mix for your chain saw or weed trimmer. The large bottle has special markings on the side, by which you can tell how much oil you have poured out of the bottle. If you bought a big 1 liter bottle, you can also buy a 20ml syringe at the drugstore. Very convenient. 1 syringe of oil for 1 liter of gasoline.
We advise you to use STIHL brand oil for your machines. it is ideal because it has been developed and tested specifically for STIHL power tools. Note that Stihl has its own brands, such as VIKING (popular models of gasoline trimmers). Also use Stihl oil for them and you won’t have any problems at all.
If you put more gasoline mixture than you can use up, it’s best to store the leftovers in a metal canister or glass container. Never store the mixture 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 gasoline mixture corrodes the plastic bottle, and microscopic plastic precipitates in the mixture, and this 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 notorious Hooksvarna. Of course, when you think about it this way, more people use STIHL chainsaws, at least all my friends and their friends use them for work only.
But there are those who cherish Husqvarna tools and I understand them, because I personally do not see much difference between Husqvarna and Stihl, and both tools are of very high quality. But I’ve seen the happy owners of chain saws Husqvarna. they say the saws are great. I have not sawn myself, but I always listen to what people have to say. So, if you have a Husqvarna gasoline tool, it is better to use a special brand oil for it. But nothing bad will happen if you dilute the gasoline with Stihl. But since a producer recommends using only his products, we will do it that way.
On sale you can meet liter capacities. A black stylish bottle with the same marking on the side as a Stil bottle (so that you know how much oil has been poured out of the bottle). Seems to me the quality is absolutely identical. This bottle costs 270, a little bit more expensive.
Both are quality oil, the cost is about the same, each diluted in the proportion of 1 to 50. So feel free to buy any, of course, it is better to take the oil of the brand you have the tool. then everything will be perfect, just as the manufacturer advises. Have a good time sawing, mowing the grass and let your power tool work for a long time without failures.
Rules for pouring mixture into different engines
The basic rule is to strictly observe the ratio in the mixture for two-stroke engines and not to use such compositions for four-stroke engines. Also observe the principle of “seasonality”. after a long stay of fuel in the tank, drain it and replace it with fresh one.
It is practical to prepare a certain amount of mixture at once in advance, so that you can promptly use it later. Follow the rules for storage:
- Keep the petrol-oil composition not longer than 3 months, because it stratifies;
- Use a container that does not let in sunlight for storage. Keep it out of direct sunlight;
- Do not place the tank near heaters.
The result of calculating the fuel mixture:
In order to measure the right amount of oil in milliliters, use a medical syringe of a larger volume, it is inexpensive, sold at any drugstore. Or use any measuring cup with graduations.
Our calculator can help you calculate the right proportion to fuel any power tool e.g.: boat motor, chainsaw, grass trimmer, lawn mower etc.д. In other words you can independently and for free calculate the correct petrol to oil ratio for two-stroke engines. Mixing instructions on the photo below.
Important, before you start the calculation please read the instruction manual, especially the paragraphs: refueling volumes, fuel mix ratio. This data is the input for the correct calculation.

The gasoline used in your power tool has a run-in period and the gasoline/oil ratio is different than recommended.
How much oil per liter of gasoline you need for your lawnmower or chainsaw
All two-stroke engines run on a fuel mixture of gasoline and oil. Fuel enters the cylinder, burns there, creating a working force on the piston, and the part of the mixture that has not had time to ignite lubricates the moving parts of the piston group.
When making a fuel mixture for a lawnmower or chain saw, you need to calculate how much oil you need per liter of gasoline, based not only on the standard proportion, but also on what brand of gasoline and oil is used. In the case of two-stroke engines, this is very important.
For trimmers, a special two-stroke oil is produced, the packaging of which should be marked “2T”. It is strictly forbidden to use automobile oil, and even more so, transmission oil. Two-stroke oil is produced in three types:
how to change oil in a 4 cycle string trimmer
It depends on the substances in the oil. Mineral oil is the cheapest and most unreliable. Its use is justified only in household trimmers that work for 30-60 minutes a day with long breaks. Most brushcutter manufacturers at this level specify that TC-W3 oil is suitable for the engine. This means you can use 2T mineral, synthetic and semi-synthetic oil.
For professional-grade brushcutters, it is advisable to buy only the oil brands recommended by the manufacturer. These are usually semi-synthetics and synthetics with special additives.
Manufacturers mark the oil with letters:
- ? TA. for two-stroke engines up to 50 cc;
- ? TV. for 50. 200 cc engines;
- ? TC. for motorcycle engines, snowmobile engines, etc.д.
In trimmers, if the type of oil is not specified in the instructions, you can pour all three modifications. How much oil to add to grass trimmer fuel depends on the tool brand and gasoline quality. Also on the package of oil there may be letters FA, FB, FC, etc.д. They indicate the smoke level. 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. This indicator does not affect the choice of oil.
The “self-mix” and “pre-mix” labels are more important. The first word means that the oil dissolves on its own, and the container with the second mixture should be shaken several times.
If the manufacturer’s instructions do not specify what gasoline to use, you must stop at AI-92. If AI-95 is recommended, do not use other brands of gasoline.
Some users believe that if you add more oil to the gasoline for the fuel mixture than necessary, it will benefit. That’s not true. Unburned oil will not leave the engine with exhaust gases, but will settle inside as fouling. This fouling threatens the integrity of the piston. If too much oil is used regularly, the grass trimmer will smoke heavily, and a drop in power is inevitable.
If there is not enough oil, the grass trimmer will overheat, the piston rings will collapse and the piston will jam. If oil deficiency is negligible, the grass trimmer will run 30 to 40% less than its service life. If the lubricant is lacking more than 20%, the motor will jam after 20 to 30 minutes of intensive work. Each trimmer manual provides proportions on how to dilute the fuel mixture. Usually 1:25. 1:40 or 1:50.
