How to dilute oil with gasoline for grass trimmer

How much oil should be put in grass trimmer per liter of gasoline

Gasoline mowers. quite common tools, used by owners of garden and homestead farms for mowing grass and making hay. common names for 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 low weight, ease of use, as well as low cost.

The most important condition for the work of 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 proportion 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 gasoline brand for brushcutters at his own discretion. This is a wrong approach, because, first of all, you need to carefully study the instruction manual, where the manufacturer’s recommendations are given for the selection of the type of fuel. 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 to choose gasoline for a particular model of trimmer for grass.

Petrol tool manufacturers recommend using gasoline brand AI-92, but for more expensive types you will need fuel with a higher octane number. AI-95. Any brand, which marking contains the figure of 90 or less, not suitable for benzokoso because it leads to rapid wear and tear. The problem is due to unscrupulous fuel producers who sell a completely different brand under the guise of 92. The situation is as follows:

  • In the passport to the gasoline technique is the recommendation to use gasoline with an octane number not lower than 92;
  • The conscientious owner goes to the gas station where the lowest price is and with a clear conscience fills the brushcutter with such fuel;
  • As a result, the service life is reduced, because often under the guise of AI-92 sold AI-80 and AI-76.

refueling

To avoid such a situation, you need to choose a filling station, which sells proven gasoline (it can be determined by the reviews of regular customers). It is also important where to fill the fuel after purchase. only metal containers should be used for this (plastic is prohibited).

Preferably, when it is possible to buy gasoline for grass trimmer high purity specifically for garden equipment. Then you can be sure of its quality and protection against fakes.

What to choose oil to fill in the trimmer for grass or types of lubricants

Grass trimmers and lawnmowers work from two-stroke engines, which have a simplified design. Rarely, but there are trimmer models with 4-stroke engines that run on pure gasoline. Power units of the two-stroke type have no compartment for filling the engine oil (oil sump), which reduces the weight of the tool and its cost. If the rotating parts of the motor are not lubricated, they will end up failing quickly. 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 available:

  • Mineral fluids. designed for low-power, air-cooled machinery. This is the cheapest type of lubricant for motors
  • Semi-synthetics. these are used for machinery that are air- and water-cooled
  • Synthetic. suitable for all types of engines with different types of cooling. They do not require frequent replacement, 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 oil with any composition. mineral, synthetic and semi-synthetic. Oils with different chemical compositions differ in price, that is why when purchasing should be based on the recommendations of the tool manufacturer. The manual should tell you what type of oil is better to use. If it is TC-W3, then the chemical composition is not important. In this case you can dilute mineral, semi-synthetic and synthetic with gasoline.

This is interesting! The main thing when choosing oil is not to get caught up in counterfeit, because now very often you can find different types of lubricating compositions for two-stroke engines, which consist mainly of low-quality petroleum products.

Features of brushcutter refuelling

Depending on the engine device, brushcutters are divided into two-stroke and four-stroke. In the first case, the piston in a combustion engine makes 2 strokes per working cycle, and in the second case. 4 strokes. Differences in the working principle of the engine and different approaches to filling the trimmer for grass.

Fueling brushcutters with two-stroke engines

As a rule, a two-stroke engine is used in normal brushcutter models. A lawn trimmer does not need very high horsepower and power, so it is well suited for the task at hand. It is also a much cheaper and simpler engine. but it is fueled with a fuel mix of oil and petrol. This fuel is filled into the carburetor and pumped into the cylinder as a petrol-oil mist. The oil thus lubricates all vital parts. When the engine is in operation, it is burned together with the petrol. But this mixture burns and emits a noxious smell and smoke, which makes the exhaust fumes more toxic.

Important! To use a special oil for two-stroke engines with these brushcutter models, it is designed for low volatility and completely burns without leaving any residue. And to mix well with petrol, they contain 20% solvent.

Filling up your brushcutter with a four-stroke engine

Four-stroke engines are used in professional brushcutter models. They have great power and can run for a long time without interruption and refueling. They also use gasoline and oil as fuels, but they are poured into different tanks. That means no oil is present in the combustion process and the exhaust fumes are less toxic.

Special note! In addition to better environmental performance and the ability to heat up less, four-stroke brushcutter engines are also more economical. They use much less fuel. savings of up to 50% on gasoline and up to 80% on oil.

Using a trimmer for garden trimming

In today’s environment, the purpose of a grass trimmer is to take care of the lawn and the area as a whole. Unlike a traditional lawn mower, the grass trimmer has some advantageous differences:

High mobility. This allows using the device in hard-to-reach and limited-sized places.

Versatility. Working bodies change depending on a type of vegetation, allowing to cut the grass of any height and hardness.

Simple design. With timely maintenance the grass trimmer does not require regular adjustments, frequent repairs.

When choosing a trimmer for grass, analyze the conditions of use of the unit, which will help make the right choice on the type and power of the engine.

How many types of motor there are

When choosing a grass trimmer by motor type, some features should be considered. Units with electric units have significant limitations associated with providing power to the motor. Low RPM diesel engines are not available for trimmers, as on tillers.

Take into account the peculiarities of the gasoline engines used:

Two-stroke cycle. Structurally simpler. demanding on the quality of the mixture at service. any deviations lead to a reduction in the life of the motor.

Four-stroke cycle. No need for a specific gasoline to lawnmower oil ratio. mixing is automatic and the working fluids are in two different tanks. The product turns out to be more expensive, but runs quieter and the exhaust is cleaner.

Regardless of the type of gasoline engine selected, oil and gasoline selection is based strictly on the recommendations of individual manufacturers.

Lubricants

Stricter criteria for choosing an oil component. At its best, it is a manufacturer-recommended mineral or semi-synthetic engine oil designed for use in high-speed, air-cooled two-stroke engines.

The advantage of mineral oils is their lower cost. Their more expensive semi-synthetic and synthetic analogues compare favorably with improved performance and compliance with environmental standards.

  • retain their operating properties in a wide range of operating temperatures;
  • do not form deposits;
  • contain detergent, antioxidant, preservative and other additives useful for power unit operation.

What oil to choose

For effective grass trimmer operation it is necessary to select oil for two-stroke engines. It is connected with absence of oil sump in such unit. Depending on the chemical composition of the oil the following classification is distinguished:

  • mineral. in the basis is an oil distillate, suitable for equipment of small capacity and with air type of cooling, but requires frequent replacement and can only be used in good weather in the warm season;
  • Semi-synthetic. suitable for garden equipment with air and liquid type of cooling;
  • Synthetic. based on esters, they do not need frequent changes and can be used at any time of year.

Oil for 2-stroke engines is characterized by good solubility and the feature of complete combustion. For a grass trimmer, it is recommended to use a lubricant that is suitable for devices with an air-cooled system. Most often the packaging indicates that the oil is designed for garden equipment and is labeled TA, TV or TC. The latter is preferable.

Often manufacturers of gasoline mowers produce a suitable oil, so you can make the choice easier if you pick up a liquid of the appropriate brand.

We deal with the choice of gasoline for lawn mower AI-92 or AI-95

So many people and so many opinions, which applies not only to the choice of oil for grass trimmer, but also gasoline. Similarly, in order not to make a mistake with the choice, it is recommended to use gasoline of the brand recommended by the manufacturer (it is specified in the manual to the tool). But it’s not that simple, because each gas station only has the same gasoline brand name, but has a completely different composition. Need to understand, and come to a single conclusion about what brand better to fill the gasoline in a two-stroke engine for your trimmer grass.

Manufacturers recommend using A-92 gasoline for their equipment, and some models require the use of A-95, which does not contain ethanol. Use gasoline AI-90, and below is not recommended, as they will entail a rapid deterioration of the engine parts. Buying gasoline of one brand, you can not be 100% sure that it is true. As a result, we get the following picture:

  • The manufacturer recommends to fill in the trimmer for grass AI-92
  • The farmer only uses gasoline of this brand, but buys it at gas stations, where the price is lower or where it should
  • It negatively affects the internal parts of the engine, because at one gas station it is really high quality gasoline AI-92, and at the second one it is at best if it is AI-80, not AI-76

As a result, the engine suffers, and after a couple of years of operation of the new trimmer for grass necessitates its overhaul. In order not to have to analyze the quality of fuel or to buy only expensive gasoline, it is recommended to fill only one filling station. At gas stations, gasoline is filled only in metal canisters, not plastic canisters.

There are manufacturers that produce special purified fuel for two-stroke engines. If you choose this option, then you do not need to choose the best gas station, gasoline brand and monitor its shelf life.

Conclusion on choosing gasoline for your trimmer!

Your trimmer for grass should be filled with gasoline of the brand recommended by the manufacturer. If you fill the tank of grass trimmer with gasoline A-95, instead of A-92 (which is recommended by the manufacturer), the engine will warm up faster and work unstably. It is also better to choose A-92 Ekto gasoline, which has improved characteristics in terms of environmental friendliness.

Fuel

It remains to choose what gasoline to fill in the trimmer for grass. The choice is not great. AI-92 and AI-95. The difference between them is quite significant. 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 gas stations, where the risk of buying AI-80 instead of AI-92 is almost zero.

If it is recommended to pour AI-95, do not use other brands of gasoline. If the engine starts, it will run irregularly and overheat quickly. So you run the risk of damaging the motor not only the domestic trimmer for grass, but also the professional.

Standard proportions

It is defined by the standard that in order to make a petrol-oil blend, you need to take technical fluids in the ratio of 1 to 50. This means that to 10 liters of gasoline, you must add 200 milliliters of oil. If you need to dilute the amount per 1 liter of gasoline, then use the formula according to the rule of proportion.

Note that when using mineral oil, the proportion is less and is 1 to 40 per liter of gasoline as standard.

Why won’t the lawnmower start??

There can be many reasons why the grass trimmer does not start.

The most common causes of difficult starting are:

  • problems with fuel quality;
  • spark plugs malfunction;
  • contamination of air and fuel filters;
  • Problems with pressure equalization in the gas tank;
  • exhaust manifold malfunction;. spark plug malfunction.

Most often these faults are not critical and you can fix them yourself. Let’s take a closer look at how to do it.

Fuel

Do not save on fuel for your equipment, use only high-quality gasoline and oil. Strictly follow the recommended proportions for the fuel mixture. It is also not a good idea to leave fuel in the tank for a long time. it will water out and lose its properties over time.

Spark plugs and spark plug passage

If a spark plug failure is suspected, immediately unscrew the old spark plug and replace it with a new one. If you can’t afford to install a new spark plug right away, clean and dry the old one thoroughly. Drain excess fuel through the spark plug passage and dry it thoroughly. Then screw the spark plug back in, check the gap of 1mm and try to start the machine again.

If the proposed manipulation did not give the desired result. check the spark plug contact. Also the lack of spark may be caused by a faulty ignition unit, which you aren’t likely to be able to repair yourself.

Air and fuel filter

If these lawnmower parts get dirty, you either have to replace them completely or clean them thoroughly. When replacing the fuel filter, do not leave the intake tube without protection. it can provoke a breakdown in the engine piston system.

Problems with pressure equalization in a gas tank

This malfunction is due to contamination of the breather valve. When this part is clogged, a vacuum is formed in the gas tank, which prevents the flow of fuel. You can clean the breather plug with an ordinary needle.

If after checking these systems of the grass trimmer it did not start, most likely the cause is a problem with the carburetor (clogged jets, broken tightness) or the engine (wear of piston rings, chips on the cylinder). Repair of this type can also be made independently, but it is better to trust the professionals at the service center.

There are few people left today who use a common scythe in their home garden. This “ancient” method is almost never met. And many already have no idea how to handle it, sharpen and rivet. With the development of technology, devices called grass trimmers appeared.

There are two basic types of these devices. These are gasoline and electric. From the name it is clear that their main difference is the power source. Each type has both advantages and disadvantages. The advantage of petrol ones is the absence of a power cord, which does not limit the owner in moving around the site during work. Electric, on the other hand, needs 220 V mains for power. There’s no way to do without the extension cord, which will always be in the way and get tangled underfoot.

Modern trimmer for grass, which runs on fuel, thanks to the presence of different interchangeable heads has turned from an ordinary grass trimmer into a means of small-scale mechanization with multiple functions. By installing the appropriate attachment, the owner will not be difficult to form a crown in shrubs on a personal garden plot. In a snowy winter, it can be used as a snowplow. Replacement of the working heads of the trimmer for grass will not take much time, and can be done with or without a tool.

What grass trimmer oil to choose?

When using such a device as a gasoline trimmer for grass, its maintenance is particularly difficult. When the time comes to change the oil, many people do not know what oil to pour into the trimmer for grass.

In each case, it all depends on the type of grass trimmer engine. In its essence, it is similar, but of higher power, used in the manufacture of mopeds. That’s why it’s necessary to use trimmer oils that are labeled 2T.

In most of these devices oil is filled with gasoline. Therefore, it is imperative for the owner to know, when using a grass trimmer, the ratio of gasoline to oil. In most cases you take 20 grams of oil per liter of fuel. The higher the quality of fuel, the lower its consumption.

There are also 4-stroke models of engines for trimmers. In these trimmer oils are poured into a separate container, which does not cause any particular difficulties. One of the main advantages of these devices is their low noise, which allows you to work without headphones. Trimmer oils are labeled 4T, which is a must to pay attention to.

Advantages and disadvantages of gasoline trimmers

Thus, summarizing the above, it is necessary to note the main advantages and disadvantages of gasoline trimmers. To the pluses can be attributed:

  • weight;
  • The amount of noise emitted during operation is greater than that of electric mowers. Despite this, the number of gasoline trimmers in the countryside is only increasing.

Oil for brushcutter. how to choose, in what proportions dilute

Many of you have a petrol tool in the household, for example, in a private home can not do without a chainsaw. You know, it comes in handy for making firewood for the winter at construction and repair, and in general, it is a very useful tool. If your country house also has a decent-sized plot, then the struggle with grass just need a trimmer for grass or lawn mower, which also work 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 up to the knee. That’s why most people prefer to work with gasoline-powered tools. As you know, you need to add to the gasoline special oil for two-stroke engines. That’s what we’re going to talk about, because this is a very important aspect, if you don’t add oil, if you add it in wrong proportions, then your engine will crack up really fast, and your way will be to the service center. To avoid all these troubles, add only quality oil and in the right proportions.

The most popular for chainsaws, brush cutters and trimmers are products of the famous company STIHL. It is sold in 2 packages. 1 liter and 100ml. For those who work a lot, a liter bottle is fine, but a small bottle is enough to “once cut”. A 1 liter bottle costs 250, while a 10 ml bottle costs 60. If you buy a large one, you will save a lot of money.

You add oil to petrol in proportion of 1 to 50, so for example for 5 liters of petrol you add 100 ml. As you can see, a small bottle is great for getting 5 liters of gasoline mixture to fill a chainsaw or grass trimmer. On the big bottle there are special marks on the side, by which you can determine how much oil you have poured out of the bottle. If you buy a large 1 liter bottle, buy a 20ml syringe at the drugstore as well. Very convenient. 1 syringe of oil for 1 liter of gasoline.

STIHL recommends you use a brand oil for your machine. it’s ideal because it has 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’ve put more gasoline mixture than you can use, it’s best to store the leftovers in a metal canister or glass container. Never store it 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 half-cup, 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, there are microscopic deposits 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 trouble free.

The second most popular oil brand is the notorious Hooksvarna. Of course, if you put it this way, still more people use chain saws STIHL, at least all my friends and their friends use in their work only.

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 the happy owners of chain saws Husqvarna. they say the saws are awesome. I have not saw it myself, but I always listen to what people say. So, if you have gasoline tool Husqvarna, 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 using only his products, that’s what we’ll do.

You can find liter capacities on sale. Black stylish bottle, same markings on the side as Stihl’s (to know how much oil has been poured out of the bottle). To me, the quality is absolutely identical. It’s 270, a little bit more expensive.

Both are good quality oils, cost about the same, each diluted at a ratio of 1:50. 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 as the manufacturer advises. Happy sawing, mowing and let your power tool work for a long time without damage.

Types of engine oils and their purpose

Choice of oil for the gasoline trimmer

Engine oil for gasoline grass trimmer is a lubricant that serves to reduce wear and tear between the rubbing nodes of the engine.

The oil composition includes residual hydrocarbons and various additives that improve the properties of the end product. To ensure long-lasting and trouble-free operation of the lawnmower, experts recommend using oils, which by their physical and chemical properties correspond to this type of motor.

Today it is customary to distinguish between three main types of oil according to the way they are made:

  • Mineral, created in the process of distillation of hydrocarbons;
  • Synthetic oils obtained through natural gas processing or 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.

Features brushcutter oil refills

In order for the mixture to be properly distributed in the fuel system of the device, you must follow a simple instruction. How to correctly fill a gasoline trimmer for grass:

  • Place the brushcutter on a horizontal surface with the filler neck up and pour in the correct amount of fuel;
  • Do not fill the grass trimmer too much. check the fuel level at the top mark;
  • Do not spill any fuel on the ground or tool body;
  • Before starting the engine, keep a safe distance to the fuel containers;
  • If there was old fuel in the tank, you must completely empty the gas tank before refilling the new.

Fueling your power tool with a two-stroke engine

To fuel a petrol two-stroke trimmer of this type, follow the already described procedure. It is necessary to strictly maintain the ratio of oil and avoid spilling on the body of the tool. Make sure that the gas tank is not overfilled, because then the engine will be unstable.

Filling up brushcutters with four-stroke engines

The main difference is that grass trimmers with this type of engine are not filled with a mixture of oil. It is necessary to fill separately the AI-92 and engine oil. The general rules for filling the tank are similar to those already described above.

What to choose oil to fill a grass trimmer or types of lubricants

Grass trimmers and lawnmowers are powered by two-stroke engines, which have a simplified design. Rarely, but there are trimmer models with 4-stroke engines that run on pure gasoline. Power units of the two-stroke type do not have a compartment for pouring engine oil (oil sump), due to which the weight of the tool is reduced and their cost is reduced. If the rotating parts of the engine are not lubricated, they will eventually fail quickly. 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 available:

  • Mineral fluids. designed for low-power, air-cooled machinery. This is the cheapest type of lubricant for motors
  • Semi-synthetic substances. they are used for equipment that has air and water cooling
  • Synthetic. suitable for all types of engines with different types of cooling. They do not 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 oil is suitable for any composition. mineral, synthetic and semi-synthetic. Oils with different chemical compositions differ in price, so you should rely on the recommendations of the tool manufacturer when buying. The instructions contain advisory information about what types of oils are best to use. If it is a TC-W3 standard, then the composition of the substance is not so important. You can dilute mineral, semi-synthetic and synthetic with gasoline.

This is interesting!The main thing when choosing an oil is not to get caught up with counterfeit, since today it is very common to find different types of lubricating compositions for two-stroke engines, which consist mainly of low-quality petroleum products.
