Gasoline to oil ratio for grass trimmer table. First run-in of the lawnmower

Hello! I bought a grass trimmer Prorab 8406 1. How to dilute petrol with oil correctly and in what proportions? I couldn’t find any original Prorab oil, so I bought Hungsvarna HP oil. It is written in the instruction manual of the trimmer that SAE MIF\4, API TC-TB oils can be used. Using other oil does not change the proportion of the fuel mixture. The standard mix ratio is 1:25. But in the specialized store, the “expert” who sold me the Hungsvarna HP oil strongly advised to dilute it by 1:50 (as it is written on the oil). Question: if the instruction says dilute oil to 1:25, but the oil is recommended 1:50, then in what proportion dilute? How much is 1:25?? 40 ml? Will I damage the engine if I use 1:50?? 2. What is the right way to run in the engine? The manual does not say anything other than start and shut off. It may not need a running-in period? I read that there are grass trimmers that you can work with immediately after purchase.

Do I need to lubricate the gearbox before working or is it already factory lubricated? Hope for your help, thanks!

1) Gasoline is ALWAYS diluted with oil in the proportion indicated on the oil can! With two-stroke products (gasoline trimmers, chain saws, etc.).) you can use any two stroke engine oil except boat two stroke engines. It’s better to use oil from a legitimate store, where there’s minimal risk of buying fake oil. Is it better to use Husqvarna or STIHL oil? STIHL oil should have a sealed neck. Beware of counterfeit products. You risk ruining your piston right away. 2) Running-in of two-stroke products is not done! REMEMBER THAT, PLEASE! All two-stroke products are high speed and like to run exclusively at full throttle! No half throttle is allowed! This causes incomplete exhaust and clogging of piston walls with oil deposits. The consequence is scuffing of the piston. So full throttle and every 25-30 seconds you dump the throttle for 1-2 seconds to give the product a break and return to normal temperature mode. 3) Gearboxes on direct driveshaft brushcutters must be relubricated every 20 hours. The oil comes out of there naturally during operation. This is done to allow dirt, dust, etc. to come out with the grease. д. So if you don’t want to end up with a gearbox change, put some special gearbox grease in it every 20 hours. It’s not hard and the whole operation takes no more than 3 minutes. You can buy tubes of grease in every garden supply store and they cost from 100 to 300. 1 tube lasts 3 years- The concept of running-in the tool is limited to running under-load during the first two or three barrels of fuel. For example, when mowing sparse, low grass, or cutting dry, undersized wood. In no case can not run the tool at idle speed burning a few tanks of fuel. As a result of such running-in, carbon deposits are formed on the cylinder windows, piston and muffler, which negatively affects the engine life.

Lawn trimmers or lawn mowers are indispensable in the home. However, its reliability, efficiency and long service life depend on many factors.

For example, the quality of fuel. This means that you need to correctly select the oil for the grass trimmer, observe the proportions when adding it to gasoline and the rules of filling the device.

Choice of gasoline for trimmers

Gasoline for trimmers should be selected according to the manufacturer’s recommendations. If these are not followed, the motor will soon break down. Often unleaded fuel with an octane rating of 92 or 95 is used to fill the gas tank of the grass trimmer.

Gasoline for the fuel mixture

Filling the grass trimmer with gasoline of the brand AI-80 can lead to device failures due to its low technical characteristics. Keep in mind that fuel after purchase can be stored for no more than 60 days, and it is better to reduce this period.

Do not use plastic jerrycans for storage. к. There will be static electricity when in contact with the inner walls. The accidental appearance of a spark will lead to an explosion. Although, there are special plastic canisters marked “flame”.

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

Grass trimmers and lawnmowers work from two-stroke engines, which have a simplified design. Rarely, but there are models of trimmers with 4-stroke motors 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 tools is reduced and their cost is reduced. 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 produced:

  • Mineral fluids. designed for low-power, air-cooled machines. This is the cheapest type of motor lubricant
  • Semi-synthetics. they are used for machinery that is air-cooled and water-cooled
  • Synthetic: suitable for all engine types with different cooling modes. 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 for grass trimmer oil with any composition is suitable. mineral, synthetic and semi-synthetic. Oils with different chemical compositions differ in price, so it is necessary to rely on the recommendations of the tool manufacturer when buying. The instructions indicate the recommended information about what types of oils are better to use. If it is a TC-W3 standard, it does not matter how the composition of the substance should be. In this case, 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 in counterfeit, because today you can often find different types of lubricating compositions for two-stroke engines, which consist mainly of low-quality petroleum products.

Peculiarities of filling brushcutters

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

Fueling a brushcutter with a two-stroke engine

As a rule, a two-stroke engine is used in common household trimmer models. The lawnmower does not need much power or speed, so it is well suited for the task at hand. This engine is also much cheaper and simpler, but it is fueled by a fuel mixture of oil and gasoline. This fuel is filled into the carburettor and pumped into the cylinder in the form of an oil and petrol mist. This way oil lubricates all the necessary parts and burns off the gasoline when the engine is running. However, combustion of this mixture is accompanied by emission of acrid odor and smoke, which increases toxicity of exhaust gases.

Important! The machine requires a special two-stroke oil that burns completely without rust and has very low volatility. For the oil to mix well with petrol it contains 20% of a solvent.

Fueling 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 stopping and refuelling. They are powered by gasoline and oil, but fill separate tanks. That means that there is no oil involved in the combustion process. The exhaust fumes are therefore less toxic.

Special Note! In addition to better environmental performance and less heat, 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.

What kind of gasoline is in a VIKING mower?

VIKING self-propelled electronic and petrol lawnmower: reviews

See also  How to Install Magneto on a Huter Trimmer

The Austrian company VIKING announced itself for the first time in 1981. Heinrich Lechner is thought to be the founder of the VIKING. In the small town of Kufstein he is engaged in the construction of garden shredders. The world saw the first VIKING lawnmowers in 1984. Since 1992 the company underwent intensive development.

This is usually attributed to the merger of “Viking” with “Steel”. They were the inventors of chainsaws. But since 2001, the company “VIKING” can boast just not a small range of lawn mowers, which are in great demand in the world. Today, the brand is a strong favourite for the production of garden tools.

What is the difference between VIKING?

At first it is fundamentally important to note that the buyer has the ability to pick up a lawn mower, which operates either on gasoline or on an electronic engine. There are also battery-powered models.

Their power rating averages around 4 kW. The working width can vary, as well as the mowing height. The cutting system is usually available centrally.

If we consider small models, they are equipped with an eight-speed gear.

The grass catcher box is supplied in a set of high quality blades. Their volume depends mainly on the lawnmower power. The frames of all models are reinforced. In the maintenance of lawnmowers actually do not need.

Blades can be cleaned quite easily after lawn mowing. The wheels of the devices are available with double bearings. Because of this, their service life is substantially increased.

VIKING lawnmowers can only be repaired at a service center.

Reviews of the petrol VIKING MB 248

This gasoline lawnmower “VIKING” reviews have excellent. Many buyers of this model are preferred because of the low fuel consumption. With all that, the power output is within the normal range. Power of this mower is 4 kW. Cutting width of the knives is 46 cm. The cutting height is 25mm minimum.

It can be adjusted with a lever. The cutting system in this case is centralized. The power of the device can be adjusted in steps. The standard feature of the VIKING MB 248 is a metal blade. Producers have provided a total of 8 different modes. For dacha this mower is excellent, and on average it can handle an area of 1200 sq.m. м.

What they say about the ME 235 electric model?

The reviews on the VIKING ride-on mower are mostly positive. This model is very easy to use. The handle is of sufficiently high quality, and to keep the device under control comes out with jewel-like precision. This lawnmower requires virtually no maintenance.

The blades of the machine are very sharp. The lawn mower copes with small grass successfully. The disadvantages are the low machine power. It is therefore more practical on small lawns. Electricity this modification consumes within the norm.

The ME 235 lawnmower rarely breaks down.

MB 448 Lawn Mower Overview

The VIKING self-propelled lawnmower is one of the most compact mowers. The cutting system in this case is a rotary.

Because of that the lawnmower can work for a long time without interruption. Rated power of the marked device is in the range of 3 kW. The small cutting height is 20 mm.

Many people find the working width to be good, approximately 30 cm.

Maximal mowing height the user can set 60 mm. The engine in this case is installed by the manufacturer of asynchronous type. The wheel drive is of the rear type.

The deck of the MB 448 is made entirely of plastic, but it is strong enough and can withstand heavy loads. In terms of noise level, this model does not differ from conventional lawnmowers.

At 5 meters the MV 448 gives out 50 dB. The standard package includes only one mowing head. Blades are installed by the manufacturer of the blade type.

Advantages of the model CF 2

This model is valued by consumers for its high performance. Continuously work it can about 3 hours. With all this the engine does not actually overheat. This was achieved by a good cooling system. But this modification also has disadvantages.

How much petrol and oil to fill a VIKING lawnmower and how often to change the oil? First, it is necessary to emphasize quite thin blades in the kit. The height adjustment on this model is very difficult.

This is due to the fact that the lever is fixed firmly enough. It is also important to note the increased vibration. When working on uneven ground, there is a great deal of shaking. As a result, the handle begins to vibrate very.

Keeping under control in such a situation is difficult for the MV 2 lawnmower.

VIKING lawnmower oil change at the end of the season

Oil change at the end of the season. Lightweight four-stroke engine with no oil.

VIKING МА 339 petrol lawnmowers

This model can boast just great features. The power of this machine is 4 kW. The grass bag is large enough to catch the grass. It can be quickly unhooked during operation for cleaning.

The cutting height can be adjusted. The cutting width of the blades is optimal. The cutting system of the lawnmower is designed as a rotary mower. There is only one nozzle in the standard set. In total there are five modes to choose from.

You can also adjust the height of the handle on the MA 339.

Consumer reviews of the MB 3

This VIKING lawn mower is not suitable for everyone, but it does have certain advantages. Users primarily note convenient operation.

Regulating the speed of the blades is quite easy with a single switch. The off button is in a convenient place and that’s good. From the disadvantages should be noted a rather large size of the device.

Features of the brushcutter refueling

When the mixture is ready and ready to use, it must be carefully poured into the fuel tank. As petrol is a poisonous liquid, it is necessary to observe the safety precautions when working with it. Working in calm weather and away from bystanders. Also, in order to pour fuel into the tank, you must use a funnel or funnel, with which you previously diluted the mixture. Otherwise the mixture may blur, remain unnoticed and become inflamed when the engine heats up.

The fuel bank itself should be cleaned of external impurities and only then unscrew its cap in order to refuel with ready fuel. After filling the fuel tank should not remain open, as insects or soil can get in the tank and clog the fuel filter. Fuel must be poured into the tank designated mark or less, and then refill during operation.

When storing, the container must be tightly closed with a lid. The fuel must be stored in a cool room, out of the sunlight. Keep in mind that during prolonged storage of the consistency of the oil liquefies and loses its characteristics.

The choice of oil and gasoline for the preparation of the fuel mixture for grass trimmer. consider

Household appliances with gasoline engines require responsible maintenance. For your lawn mower to work reliably for a long time, it is important to use fuel and lawn mower oil according to the owner’s manual. Two-stroke gasoline engines work with the addition of oil to the combustible mixture, four-stroke have a separate tank in the fuel tank.

Recommendations for Storing Ready Grass Trimmer Fuel Mix

After filling up the grass trimmer, many people save the remaining mixture in the bottle until the next time. Sometimes this next time comes not soon, and stretches to the next year. It is not allowed to store the ready to use mixture for such a long time, because the oil decomposes. After preparing the mixture, use it up within 1-2 weeks. Besides, you should not store the tool with the fuel mixture in the tank for a long time, because the effect will be the same. To prevent unforeseen circumstances, it is recommended to consider the following recommendations for storing a ready mix of gasoline and oil:

  • Mix the fuel in the quantity you will use. If you do not know how much fuel you are using, it is better to prepare less
  • If fuel mixture remains in the grass trimmer’s tank (when the tool is hidden until the next season), it must be completely used up or drained
  • Stir the mixture thoroughly before pouring it into the tank
  • Store ready mixture in a tightly screwed container and in a place restricted to sunlight

If you follow all the recommendations, the life of the grass trimmer will be at least as long as the instructions. Using quality consumables paired with following the recommendations for the grass trimmer mix will result in a long and efficient service of the gasoline tool.

Oil to Gasoline Ratio for Lawnmower

The introduction of lawn mowers on the market has made lawn care a lot easier. Depending on the engine model, there are two types: gasoline and electric. If you choose between these options, gasoline is preferable because it is much more mobile. It doesn’t require wires and an electrical outlet.

To help care for the lawn as long as possible, the shrubbery mower must be carefully monitored and regularly serviced.

Amount of oil per liter of fuel

There are two types of engines on the lawnmower. four-stroke and two-stroke. There are some major differences between the two. The first option has a separate oil and gasoline supply, t.е. No need for a special fuel mixture.

And the second type of engine requires constant lubrication of engine parts by mixing fuel and oil in a certain proportion.

The fuel mixture consists of gasoline and special oil for two-stroke engines. When choosing oil, it is recommended to use oil from the same manufacturer as the lawnmower, but this is not a fundamental problem.

The main thing is that the oil is of high quality and not a cheap knockoff. in this case there is no need to save money.

You can tell two-stroke engines from the label. This also indicates in what ratio the oil should be diluted with fuel. With good, quality oils, the dosage is usually: 1 part oil to 50 parts fuel, i.e. 2% of the fuel. Some owners are confused about these proportions. It’s really quite simple.

If the label says 50:1, this means that 100 grams of petrol must be filled with 100 grams of oil. In other words, it takes 20 grams of oil per liter of gasoline to lubricate engines.

How to prepare the fuel solution

Please read the instructions carefully before starting. Never just “by eye”. Each manufacturer adds fuel to its components, so it will be helpful to read its recommendations.

The basic rules for making fuel for a two-stroke engine are.


    Lawnmower oil: with 4-stroke engines, what kind of oil to use, petrol, change

    Preparation, mixing, and changing the fuel-air mixture are the main maintenance procedures for the lawn mower. The quality and composition of the fuel and lubricant used depends on the durability of not only the rotating parts, but also the engine.Lawnmower oil covers rubbing parts and clearances between parts with a thin binding film, which reduces wear and scratches in operation.

    What kind of oil to fill

    When selecting a lubricant, the main factors to consider are:

    • ensuring engine cooling, protection against thermal shock;
    • operation at high revolutions and under high loads;
    • corrosion resistance during winter downtime of the mower;
    • absence of soot and sulfate ash, smokeless;
    • environmental friendliness;
    • good gasoline solubility
    • storage time of prepared lubricant.

    Lawnmower oil must meet the requirements of biodegradability, all-season performance and economy.

    2-stroke engines require a mix in the manufacturer’s recommended oil to gasoline ratio. For four-stroke engines, no mixing is done; the ingredients are poured separately into different containers. Lubrication is by means of oil pipes, pump, filter and valves.

    For the lubricant use the types of oil that are most suitable for 2-stroke units:

    The fluid contains 5-15% of various additives designed to improve performance, slow down corrosion, and stabilize viscosity.

    Lawnmowers with 4-stroke engines require a simple automotive fluid, e.g. SAE30 or 10W40, with the right technical characteristics. The SF formulation is suitable for almost all vehicle brands. To operate in winter, a frost-resistant fluid is poured.

    What kind of gasoline to fill up

    Gasoline for the lawnmower is the second element of the fuel mixture. Its brand should be chosen according to the manufacturer’s recommendations, described in the passport of the unit. The longer the fuel burns and its resistance to detonation is indicated by the octane number: the higher the number, the longer the fuel burns. Thus, at gas stations you can buy such grades of petroleum products:

    See ” Top 4 Robotic Lawnmower Models on Radio Control

    AI-92 has a greater tendency to detonate.

    When using fuel with a higher octane rating than the one in the manual, it damages the engine in 2-cycle engines and the piston group in 2-cycle machines with a lower rating.

    The mixture is prepared before use in the proportion that is indicated on the gasoline tank cap:

    This means that you need 20 ml of oil per 1 liter of fuel.

    Lawn mower with a 4-stroke engine does not require oil preparation. There are two tanks in the equipment. Fill the tank with petrol and the oil through the drain hole in the crankcase.

    oil change

    • turn on the mower and let the engine idle for 15 minutes
    • the cap in the tank opening must be unscrewed;
    • put a container in front of the trimmer to catch the used oil;
    • tilt the unit towards the side of the drain;
    • after draining the used oil screw up the plug;
    • place the mower on a flat surface and open the top opening;
    • fill up the oil to the required level, check the level with the dipstick;
    • close the hole and screw in the plug.

    The volume of liquid poured in most units reaches 500-600 ml.

    What kind of gasoline is needed for the grass trimmer?

    the brand of gasoline that is suitable for a specific model of tool is usually specified in the instructions. Ignoring the manufacturer’s recommendations and filling the tank with the wrong octane rating will eventually cause the unit to malfunction. Weed trimmers are available with two and four stroke engines. Their refills and maintenance are very different.

    Two-stroke grass trimmers do not have a separate oil system to lubricate the working parts. That’s why they should not be filled with straight gasoline but with a mix of diesel and engine oil. Remember that oil should be specially formulated for two-stroke engines. Using engine oil can damage the tool.

    STIHL 2-stroke grass trimmers should be filled with 92o petrol. Surely it can operate on higher-octane gasoline. But if you fill the tank with AI-95 gasoline, the engine will overheat and run unevenly.

    What Gasoline to Use with a Grass Trimmer

    Mix the oil and gasoline in the correct proportions. If the lubrication is too low, the surface of the piston and the cylinder walls will crack, then the piston ring will fall apart and the engine will jam. Too much oil is not so critical, but it can have some nasty side effects. Sludge builds up on the piston and the piston ring gets caked, causing the power to drop.

    As a rule, the proportions of gasoline and oil are given in the appliance instructions. Many manufacturers specify a 50:1 ratio. one part oil in 50 parts fuel. So there should be 20 ml of oil per gallon of fuel. If the engine is worn out or the tool is under heavy load, the amount of oil can be increased to 25: 1, pouring 40 ml per liter of gasoline.

    Four-stroke gasoline grass trimmers

    Grass trimmers with a four-stroke engine have a more advanced device. Gasoline and oil are poured into different containers, from where they enter the engine. These models do not allow the use of lubricants for two-stroke engines.Gasoline for grass trimmer with such an engine must be AI-92 or AI-95. Do not use fuel with a lower octane rating. This would make the engine unstable.


      Grass trimmer oil: selection and proportions

      A huge role on the performance and durability of the gasoline trimmer for grass is played by oil, which protects the parts of the cylinder-piston group from rapid wear and tear.In order for the lawnmower to please its owner with trouble-free operation it is necessary to take a competent approach to maintenance. Currently, it is accepted to distinguish between two main types of engines by the number of work strokes: the principle of two-stroke and four-stroke engines

      • Two-stroke engines where oil is added directly to the fuel tank;
      • Four-stroke engines with a separate oil reservoir. An exception to this is the STIHL 4-MIX engine that runs on a petrol-oil mix but has four strokes.

      Nevertheless, the majority of trimmers presented in our market are equipped with power units running on a mixture pre-prepared poured into the fuel tank.

      Types of engine oils and their purpose

      Choice of gasoline trimmer oilThe engine oil for the gasoline grass trimmer is a lubricant that reduces wear 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 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 oils according to the way they are produced:

      • Mineral, created in the process of distillation of hydrocarbons;
      • Synthetic oils, obtained through the processing of natural gas or by synthesis;
      • Semi-synthetic, incorporating an improved mineral oil with the addition of some synthetic components.

      In order to prevent the mixing of different types of producer adds a dye to the oil, which shows the difference in the composition of the lubricant.

      Choice of lawnmower oil

      For trimmer engines, you should choose oils marked “2T”, which are used for engines with a volume of 50 to 200 cm3 and are air-cooled. The first thing to look for when buying oil is not the price but the protective properties of the material, since small savings can later turn into a real headache for the owner and, as a rule, large expenses.

      The main factor that determines the quality of grass trimmer oil is the alkali number. It is this component that eliminates oxidation of rubbing parts and slows down their destruction. During use the oil gradually loses its alkalinity and becomes oxidized. The optimum level of acidity (Ph) is 8. 9.

      The viscosity of brushcutter oil also has a big influence on the working process of a gasoline-powered tool. This indicator determines the ability to operate the grass trimmer at different temperatures. For example, summer brands of lubricants become thick even at a slight drop in temperature. As lawnmowers are used exclusively in the spring and autumn, an oil with a summer grade is an excellent choice.

      The flash point for grass trimmer oil should be over 225C, otherwise the oil will burn out quickly and the piston group will be subjected to intense wear and tear.

      What to pay attention to when choosing oil?

      Modern two-stroke brushcutter engines are filled with a mixture of gasoline AI-92 and oil marked “2T”. The use of fuel with a higher octane number will increase the flash point and, consequently, the burnout of the lubricant.

      Undoubtedly, the best oil for trimmer for grass is the one recommended by the manufacturer, but the owner does not always have the opportunity to buy exactly “branded” lubricant. Experts recommend Shell Helix Ultra, based on Pureplus technology, which helps improve the basic properties of the lubricant.

      How much oil in gasoline for grass trimmer

      Answers to the question What gasoline is needed for the grass trimmer and how much oil to pour? In the category Animals and plants on the Otvet portal.expert

      Gasoline 92. And the oil ratio is written on the oil tank and it depends on its viscosity. In most cases, it’s 1 to 50 (20 grams of oil per liter of gasoline).

      I’m not very well versed in such things, just know that the brand of gasoline is depending on the type of trimmer for grass (in other words, in the annotation specifies what brand of gasoline needed and how much oil you need), but here I found a site and a forum where you have the right data.

      We have a grass trimmer. Usually he takes a dural canister and goes for 92 gasoline. How much oil to use should be written in the trimmer manual or on the trimmer. Look closely at the grass trimmer that you have. It should be 1:50, 1:40, 1:20. This is the ratio of oil to gasoline.

      You need 92 gasoline for your grass trimmer, but AI-95 is better. Everything is written better in the instruction manual. If there is no such a thing, then somewhere on the tank should be an indication of the proportion of oil to pour. There is a rule that it is better to overfill oil than underfill. 1:20 here and there they say 1:40 in other trimmers. Look closely at your own grass trimmer.

      For each brand grass trimmer you need a mixture of gasoline and engine oil in a certain proportion. The manual usually says what ratio would be good. Some manufacturers, like STIHL, have premixed fuel for their products.

      How to dilute petrol (AI 92) for grass trimmer.

      For grass trimmer you need 92 gasoline usually, I have not heard of any other fuel, to be honest. And here’s how much? Look closely at your trimmer for grass, it should say the ratio of oil to gasoline, these figures may look like 1:50 or 1:20.

      Gasoline must be of the brand that is specified in the instruction manual of the grass trimmer. Usually it’s AI 92 to AI 95. You should use a special oil for two-stroke engines, in the ratio of 50 ml per liter of gasoline. oil

      You can use either 92 or 95 gasoline. And here’s how much oil to pour have to look in the instruction manual to your trimmer or look for the inscription on the body of the “bull. If you can’t find it, dilute it in the ratio 1:40. It’s better to overfill a little than underfill.

      Gasoline for grass trimmer is usually used either ninety-second or ninety-fifth. I cannot say what the proportion is, it is necessary to read the instructions on the package, because it (proportion) depends on many factors.

      Mowers can be different in my mower, I fill my 92nd gasoline. The proportion for five liters of gasoline is 200 milliliters of oil. And you can pour that mixture in as much as you can fit in the tank. Do not be stingy with the oil.

      The engine in a trimmer and a regular chainsaw is almost the same. All fill with 92 gasoline (check with the manufacturer, but other types of fuel, I have not yet seen). And how much oil. it already depends on the oil itself (read the label). I usually dilute 100 grams of oil in 5 liters of gasoline. enough gasoline to mow a 9 acres of land. And remember, gasoline diluted with oil can not be stored for a long time.

      How much oil to put in gasoline for grass trimmer

      What gasoline is needed for the grass trimmer and how much oil to pour?

      92rd gasoline. And the share of oil is written on the container with the oil and depends on its viscosity. Most often it is from 1 to 50 (20 grams of oil per liter of gasoline).

      I’m not very knowledgeable about such things, only know that gasoline depends on the type of trimmer for grass (that is, the instructions specify what brand of gasoline is needed and how much oil is needed), but I found a website.Where you have the data you need.

      We have a grass trimmer. It usually takes an aluminum canister and goes for 92 gasoline. How much oil you need in the trimmer’s manual or the trimmer itself. Look closely at the grass trimmer you have. Should be the numbers 1:50, 1: 40,1: 20. This is the ratio of oil to gasoline.

      Gasoline is required for the grass trimmer is 92, but AI-95 is better. It is better about everything that is written in the instructions. If they are not there, then somewhere on the tanker should indicate the proportion in which you need to pour the oil. There is a rule of thumb that it is better to pour oil than to recharge. 1:20 somewhere they write, and other trimmers have 1:40. Look carefully at your trimmer for grass.

      For each brand of grass trimmer you need to have a mixture of gasoline and in a certain proportion. Usually the manual specifies what ratio would be optimal. Some manufacturers, like STIHL, make ready-to-use fuel mixtures for their products.

      Peculiarities of filling the brushcutter

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

      • Place the brushcutter on a horizontal surface so that the neck of the tank is at the top and pour the required amount of mixture;
      • Do not fill the grass trimmer too much. watch how much fuel is at the top mark level;
      • Do not spill any fuel on the ground or on the body;
      • Before starting the engine, ensure a safe distance to the fuel tanks;
      • If there was old fuel in the tank, you must completely empty the gas tank before refueling with new.

      Fueling your brushcutter with a two-stroke engine

      To refuel gasoline trimmers of this type, you must follow the instructions already described. It is necessary to keep the oil ratio strictly and not to spill it on the body of the tool. Make sure that the gas tank is not overfilled, because then the engine will not work steadily.

      Filling the brushcutter with a four-stroke engine

      The main difference is that grass trimmers with this type of engine is not fueled with a mixture of oil. it is necessary to fill up Ai-92 and engine oil separately. General rules for filling the tank are the same as those already described above.

      What to choose oil to fill in the trimmer for grass 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. Two-stroke power units do not have an engine oil compartment (oil sump), which reduces the weight and cost of the tool. If the rotating parts of the motor will not be lubricated, then they will quickly fail. To prevent this, the grass trimmer is not filled with pure gasoline, but a mixture with oil. What oil to dilute with gasoline for grass trimmer?

      Let’s start by remembering or finding out what types of oils are available in terms of their chemical composition:

      • Mineral fluids. designed for low-power, air-cooled machinery. This is the cheapest type of lubricant for motors
      • Semi-synthetics. they are used for machinery that has air and water cooling
      • Synthetic. suitable for all types of engines 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 for the grass trimmer is suitable oil with any composition. mineral, synthetic and semi-synthetic. Oils with different chemical compositions differ in price, so rely on the recommendations of the tool manufacturer when buying. The instructions give recommendations on the type of oil to use. If it is a standard TC-W3, so it is not so important what should have the composition of the substance. In this case, you can dilute mineral, semi-synthetic and synthetic with gasoline.

      This is interesting!The main thing when choosing an oil is not to fall for a fake, as today you can very often meet different types of lubricating compositions for two-stroke engines, which consist mainly of low-quality petroleum products.
