Brand of gasoline suitable for specific model tool, usually indicated in the operating instructions. If you ignore the manufacturer's recommendations and fill the tank with fuel with the wrong octane number, over time, the device may simply fail. Trimmers come with two-stroke and four-stroke engines. Their refueling and maintenance differ significantly.

Gasoline trimmers with two-stroke engine

Motor trimmers equipped with a two-stroke engine do not have a separate oil supply system for lubricating rubbing parts. Therefore, they need to be filled not with pure gasoline, but with a mixture of it and motor oil. Remember that the oil must be special, intended for two-stroke engines. Using automotive engine oil may damage the tool.

Trimmers with a two-stroke engine should be fueled with AI-92 gasoline. Of course, it can also run on higher octane gasoline. But when refueling with AI-95 gasoline, the engine will overheat and run unevenly.

You need to mix oil and gasoline in the correct proportions. If there is too little lubrication, scuffing will appear on the piston surface and cylinder walls, then the piston ring will collapse and the engine will seize. Excess oil is not so critical, but it will also lead to unpleasant consequences. Carbon deposits will form on the piston and the piston ring will become coked, resulting in a loss of power.

Typically, the proportions of gasoline and oil are indicated in the instructions for the tool. Many manufacturers prescribe a ratio of 50:1 - one part of oil is poured into 50 parts of fuel. Therefore, for one liter of fuel there should be 20 ml of oil. If the engine is worn out or the tool is working with high load, the amount of lubricant can be increased to 25:1 by pouring 40 ml per liter of gasoline.

Gasoline trimmers with four-stroke engine

Trimmers powered by a four-stroke engine have more complex device. Gasoline and oil are poured into different containers, from where they are then supplied to the engine. In such models you cannot use lubricant intended for two-stroke engines.
Gasoline for a trimmer with such an engine should be AI-92 or AI-95. It is not recommended to use fuel with a lower octane number - this will lead to unstable work engine.

Many trimmer manufacturers strongly advise using fuels and lubricants, released under their own logo. They often stand more expensive than analogues sold under other names. Is it worth overpaying for branded oil?
Companies that manufacture gasoline tools do not produce fuels and lubricants. They purchase these products from companies involved in the production of oils, and then pack the lubricant in containers with their symbols. So you can safely buy suitable oil any manufacturer. The main thing is that it matches the engine parameters.

Tip 2: What trimmer oils should you use?

In order for the trimmer to serve faithfully for a long time, it is necessary to take a serious approach to its maintenance. One of the important aspects Maintenance trimmer is the choice of engine oil.

Trimmers have become indispensable assistants in many garden plots. They are capable of performing the functions of a whole range of hand-held garden tools used for cutting grass, trimming bushes or trees, and even removing snow. Modern mechanisms characterized by reliability and long service life, which also depends on the application the right type oils Owners of gasoline saws and similar units will not have any difficulties servicing the trimmer: most use the same oil.

For two-stroke engines

Most trimmers have a two-stroke engine, which, although it has a simple design, still requires close attention during maintenance. To refuel two-stroke engines, a mixture of gasoline and oil is used in a certain proportion. It is this ratio that plays a decisive role - it must be clarified when purchasing a trimmer. As for oil, almost any lubricant marked 2T is suitable. Of course, manufacturers expensive instrument require the use of fuels and lubricants according to the established specification, but for most trimmers oils such as Mobil 2T+, Liqui Moly Motorrad 2T or Castrol Power1 Racing are suitable. The average amount of oil added is about 20 g per 1 liter, however, over time, the amount of lubricant can be determined experimentally by the presence of soot on the spark plug and the degree of contamination of the carburetor.

For trimmers with a four-stroke motor

Four-stroke engines have a separate tank for filling oil. Such power units are more sensitive to oil quality than two-stroke ones, although there should not be any special problems with servicing trimmers with a four-stroke engine. For inexpensive trimmers, the Mannol Quad or ZIC 4T line of oils is well suited. For trimmers that have been in use for more than three years, it is recommended to fill them with oil with cleaning and restoring additives. In this case, you can use XADO Atomic Oil 4T, which contains a whole complex of additives and has a high viscosity - 10W60. In most cases, semi-synthetic oils of medium viscosity 10W40 from medium price category.

Is an oil change required?

If the trimmer does not experience extreme loads during operation, the service life of the oil is approximately comparable to the service life of the engine itself. Often all that is required is monitoring the level and timely adding oil. However, the condition of the engine lubricant must be monitored from time to time for blackening, the presence of suspension and other signs of aging. In these cases, it is recommended to change the oil completely.

Household appliances with gasoline engines require a responsible approach to maintenance. In order for the tool to enjoy trouble-free operation for a long time, it is necessary to use fuel and oil for the lawn mower according to the instructions for technical operation. Two-stroke gasoline engines operate by adding oil to the fuel mixture, while four-stroke engines have a separate reservoir in the fuel tank.

Types of motor oils, their purpose

Motor oil is a special composition consisting of a solvent and additives that reduce friction, create the desired fluidity and prevent thickening when the temperature drops.

According to the method of obtaining the composition there are:

minerals obtained during the distillation of oil;
synthetic – by synthesis or processing of natural gas;
semi-synthetic – improved mineral oil due to the introduction of synthetic components.

For safety reasons, so as not to confuse the products, the oil is colored red, blue or green color. The assortment varies in composition; the user needs to buy oil marked: “for gardening equipment» 2T, if you need to prepare a mixture for two stroke engine, 4T for filling into the crankcase.

Synthetic and mineral oils have different basis, you cannot mix them. When switching to another type of oil, the system must be thoroughly flushed.

Oil for lawn mowers should be classified as vehicle oils intended for air-cooled engines with a combustion chamber volume of 50-200 cm3. When choosing a product important parameter is not the price, but the protective properties for the engine specific brand. Therefore, first of all, they buy the recommended oil; if it is not available, they select one that is identical in terms of performance.

The alkaline number determines the quality of lawn mower oil. Alkali neutralizes the oxidation process of rubbing materials and slows down the destruction of the surface. When oil becomes oxidized, it loses its protective properties. The normal pH of oil is 8-9 units.

An important indicator is viscosity. Therefore, there are winter, summer and all-season oil. Which oil to use depends on whether the user will work at sub-zero temperatures. Summer oils thicken even with slight cooling. The flash point shows how quickly the oil will burn out of the composition. It is optimal if this indicator is more than 225 0 C.

The use and importance of oil in a two-stroke engine

Engine operation is associated with friction of moving parts of the cylinder and liner, cams, and hinges. When parts rub, the surface heats up, and when they expand, scuffing occurs. If in the gap between the mating parts there is a compound in the required proportion oil and gasoline for lawn mowers, a number of problems are eliminated:

parts in the engine operate with reduced friction and heat up less;
lubricant in the gaps prevents corrosion of parts during long-term storage and washes out particles produced by friction;
engine service life is extended.

The appearance of additional properties is facilitated by the additives used, contained in the oil in an amount of 5-15%. It is the additives that create the anti-corrosion, anti-wear and frost-resistant properties of oils.

An incorrect oil composition can destroy the engine by forming carbon deposits in the cylinders, leading to coking and rapid wear motor.

It is important to know how much oil you need to add to the gasoline for your lawn mower. First of all, you should study the instructions and follow the recommended proportions. Using a composition that takes into account the engine model and configuration, climatic conditions and load will extend the life of the lawn mower. Experienced users advise that when purchasing a tool, immediately buy the recommended oil in reserve.

Requirements for the fuel mixture for a two-stroke engine

The difference between a two-stroke engine is its increased power compared to a four-stroke engine. Combustible mixture it is prepared in a certain ratio of gasoline and special oil. The optimal ratio of oil to gasoline for a lawn mower is written in the instructions. The recommended proportions must be followed exactly. When adding additives, the manufacturer took into account the type of engine. Therefore mix various oils prohibited.

Applying mineral oils, mixing occurs in the proportions of 1:25, 1:30, 1:35. For synthetic oils, a ratio of 1:50 or 1:80 is used. This means that in each of the proposed mixtures the required amount of oil is dissolved in the volume of gasoline. You can mix gasoline with lawn mower oil like water and syrup. It is necessary to pour gasoline, add the exact amount of oil and shake the mixture. It is advisable to use fresh solution for work. If stored for more than 2 weeks, the composition changes, and the oil film will cause carburetor malfunctions.

PET bottles must not be used for diluting and storing flammable mixtures. Gasoline destroys plastic, the polymer dissolves in the combustible mixture and further deteriorates the quality of the fuel, creating the danger of stray currents.

Choosing the right oil for lawn mowers

Two-stroke engines are fueled with a mixture of unleaded gasoline and oil marked 2T. In this case, you need to use the recommended AI-92 gasoline. If you use a brand with a higher octane number, the flash and combustion temperature will be higher, and the valves will burn out prematurely. The same applies to butter. The recommended composition is not the most expensive. But using another brand is unacceptable. The viscosity will change, this will lead to insufficient lubrication of conventional products made without high-precision lapping.

If oil is added in excess, incomplete combustion will lead to the formation of soot and excessive exhaust into the atmosphere. Rich mixture harmful to the engine. For a four-stroke engine, oil is poured separately from gasoline. It washes the components, cools them, and reduces friction. During operation, the oil becomes contaminated and must be replaced after 50 working hours. What kind of oil to pour into the lawn mower is indicated in the passport. The composition must be marked 4T with a viscosity of 10W40.

The best oil for any engine is the recommended one. However, Shel Helix Ultra oil is world famous. The company has been developing for 40 years new technology obtaining synthetic oil from natural gas. Pureplus technology made it possible to obtain an improved base oil composition. On its basis, with the addition of the necessary additives, leading manufacturers obtain recommended oils for their equipment.

The choice of oil primarily depends on the manufacturer’s recommendations. So, only branded oil is used. The same oil is suitable for the Vityaz brand, since the engines are of the same brand. There is an opinion among experts that oil from any manufacturer intended for one type of equipment is suitable for use on all brands. But if possible, it is better to use the recommended one.

You should have a supply of oil as needed for one season. A product that has stood for a long time loses its properties. Packages from 0.1 to 5 liters are available for sale.

The path of the oil recommended for... The company does not have its own production, only a bottling shop. A product purchased in bulk is bottled into small containers, labeled and supplied to the retail chain. It is possible that exclusive additives for Husqvarna were added to the oil at the manufacturing stage.

The use of oil, according to the operating instructions for the brush cutter, is mandatory. The equipment cannot operate on pure gasoline.

Oil dosage for lawn mowers - video

So, have you finally become the owner of a gasoline brush cutter or lawn mower? And your imagination is already creating images of how you bravely cope with thick grass. However, the dream of an “ideal lawn” remains a dream when the question involuntarily arises: what oil to use and what are the proportions of mixing it with gasoline?

Information on proper preparation fuel mixture You can find a lot of things on the Internet. This topic is actively discussed on forums and other thematic resources. But despite such active discussion, there are still many inconsistencies that have to be dealt with.

In fact, it doesn’t matter what equipment is used, it could be a lawn mower, a brush cutter or a chain saw, they have one thing in common - two-stroke gasoline engine. Unlike the 4T, it does not have an oil sump. To power it, it is necessary to prepare a special fuel mixture consisting of gasoline and oil. The resulting liquid is supplied directly to the engine (carburetor). During use, all actively working parts are thoroughly lubricated, facilitating trouble-free operation under any operating conditions.

Motor oil for lawn mowers

Depending on the chemical composition, lubricants are divided into the following main groups:

Mineral. They are made on the basis of oils obtained from petroleum distillates. They have high viscosity and require frequent replacement. The material is intended for low-power equipment with an air cooling system. Recommended for use in warm weather.

Semi-synthetic . They represent a kind of “golden mean”. They are based on a mixture of mineral and synthetic oils. This lubricant can be used in 2T and 4T engines, gardening and other air- and liquid-cooled equipment.

Synthetic. They are made on the basis of special synthetic components containing esters. They have low viscosity and long term operation. Can be used all year round, regardless of temperature conditions. Ideal for complex equipment designed to operate in harsh conditions with constant variable productivity.

Any two-stroke oil, thanks to its 20% solvent composition, mixes well with fuel and has the feature of complete combustion. Their second characteristic feature is their color, which can be green, red or blue. Of course, this does not mean that some lubricant some are better, some are worse. This is done solely to make it convenient for the user to distinguish oil from pure gasoline.

Classification of motor oils:

The necessary parameters of oils for 2T engines are specified in the requirements of API TC JASO FC, API TC JASO FC ISO GD and API TC JASO FC E-GC. Most widespread received API classification systems. Based on this, 2T motor oils are divided into 4 large groups:

T.A.- suitable for household appliances with an air cooling system and an engine capacity of no more than 50 cm3.

TB- used for more powerful equipment with air system cooling and engine volume 50 - 200 cm3.

TC- used in equipment with high demands on oil quality. This is a high-quality lubricant for two-stroke engines with a volume of 50 - 200 cm3. Great for lawn mowers, walk-behind trimmers, chain saws and other garden equipment.

T.D.- for hanging boat motors with liquid cooling.

The most suitable material for 2T motors of the API-TB and API-TC classes. However, you must refer directly to the product passport, where the manufacturer indicates the brand of motor oil recommended for its equipment.

Important! For brush cutters, lawn mowers and other 2T garden devices, a special engine oil for two-stroke engines with an air cooling system and marked " for garden equipment». It is prohibited to use lubricant for 2T engines with a liquid cooling system. The oil is also not recommended for use on outboard engines, motorcycles, or other equipment.

The ratio of oil and gasoline for lawn mowers: why is it so important to be accurate?

As children, we all loved to “mess up”, so the process of preparing the fuel mixture is not only simple, but also interesting. First of all, it is worth considering the fact that the proportions of the mixture may be different. It depends on the engine configuration, oil markings and manufacturer's recommendations. The fact is that if there is insufficient amount of lubrication, heating of the cylinder and piston occurs, which leads to shallow scuffing of all rubbing surfaces and, consequently, to failure of the cylinder - piston group. Well, if there is an excess of it, on the contrary, we get coking of the piston ring and the formation of a large amount of carbon deposits.

And even despite the fact that there is a generally accepted mixture ratio of 2% (for every liter of gasoline 20 ml of lubricant). It is still recommended to maintain the proportions in the mixture exactly.

How much oil to pour into gasoline for lawn mowers?

Everything is quite simple, if the correct balance is maintained, the engine runs in in full, all parts are thoroughly lubricated and do not wear out. As a result, we get confidently working equipment that will last for more than one season.

To know how much oil to add to your lawn mower, you need to read performance characteristics products. Proportional ratios can be presented as follows: 1:25, 1:40 and 1:50, which which means 1 part oil to 25, 40 or 50 parts gasoline.

For example:

1 liter of gasoline = 1000 ml

To determine the required amount of oil for a ratio of 1:25, we need 1000 / 25 and we get a proportion of 40 ml.

We perform the same steps for the ratio 1:40 and 1:50:

1:40 (for 1 liter of gasoline 25 ml of oil)
. 1:50 (per 1 liter of gasoline 20 ml of oil)

To ensure that the proportion of oil for the lawn mower is correct, it is recommended to use a special measuring container (not plastic). Avoid the possibility of dirt and water getting into the fuel mixture - this may affect its quality. It is better to start preparing the mixture with gasoline. Fill it to the required mark, then add oil. A couple of tilts of the container are enough for mixing. The liquid quickly combines and acquires a uniform shade, which, depending on the structure of the oil, can be red, green, blue or another. After which the correctly prepared mixture is poured into fuel tank equipment.

Before you start using the equipment, make sure that the tank lid is tightly closed. If you have more fuel, the remainder can be stored in a special canister or mixing container (no more than 14 days). It is recommended to drain fuel that is not completely consumed.

Important! Be sure to follow safety regulations. Mix liquids in an open area to prevent caustic gasoline fumes from accumulating indoors. Wear gloves and long sleeves. Don't smoke or set anything on fire.

Petrol

Gasoline with an octane rating of AI-92 is considered the most popular type of fuel for two-stroke engines. Due to its relatively low cost, it is extremely rarely falsified. Therefore, it is not one hundred percent, but you can be sure of its quality. It is also permissible to use AI-95 fuel.

As for fuel storage, its period should not exceed 3 months. Over time, gasoline loses its properties, the resin content becomes higher and a polymerization process occurs, which adversely affects the combustion chamber. Fuel mixture for lawn mowers made from non-alcoholic quality materials, settles in the form of carbon deposits, as a result of which the main components and systems of the engine suffer.

The fuel is ready, poured into the fuel tank, the first push and the long-awaited start. However, if you want the equipment to work for as long as possible, it is recommended to run it in for the first time. To avoid engine overheating, it is recommended to adhere to medium load. After the main elements of the system are thoroughly lubricated, the load can be increased.

Certain rules should also be followed when preparing the braid for off-season storage:

Drain the remaining fuel from the fuel tank and carry out the final drive until the fuel is completely depleted. After that, stop working and make sure that the engine has cooled completely.

Carefully remove the spark plug and add about 5 ml of lubricant. Pull the starter handle slowly to distribute the oil evenly throughout the engine. After that, return the candle to its original state. The equipment must be stored in a cool, dry place.

Results

We hope that the above general information, will help you navigate the main question - which mower oil to use and in what proportions to mix it with gasoline? After doing this step just once, you will realize that it is very simple. You can buy a brush cutter and oil for it in our online store. And remember that only when proper care and the use of high-quality materials, the equipment will serve you for as long as possible.

Answers to the question How true breed gasoline as oil for lawn mowers, what kind of gasoline is needed? in the Science and Technology section on the Otvet.expert portal

How to do it right breed gasoline oil for lawn mowers, which one is needed petrol?

To prepare a fuel mixture for a lawn mower, you should firstly have gasoline of a grade not lower than AI92, and secondly, a special synthetic oil for two-stroke engines and thirdly a clean mixing container. Although many people simply pour gasoline into the tank first, and then oil, and lightly shake the mower. As a rule, the required ratio of gasoline and oil is indicated in the passport, but if it is lost, then you can mix the components in a ratio of 1:40 and you can’t go wrong. That is, one liter of gasoline requires approximately 25 grams of oil. Changing the oil in a lawn mower oleo mac. This may be exactly the volume of a standard cap from an oil container. By the way, the excess slightly increases the smokiness of the mixture during operation, and therefore the soot.

I dilute gasoline with mower oil in a three-liter jar. Changing the oil in a lawn mower video. For 1 liter of gasoline 93 or 95, I pour 1 cap (a cap from a bottle of oil). This is what my dad taught me, and he has been working with engines for more than 40 years. My mower is already 7 years old and has never (ugh 3 times) broken down.

My father dilutes gasoline in a one and a half liter plastic bottle for mower. Reason for brushcutter leaking oil. He pours gasoline into the bottle not to the brim, but just as the water was originally poured there. Then he pours half a glass of oil into it. Changing the oil in the lawn mower engine. Change of oil trimmer patriot. This faceted glass contains 100 grams, which means he pours 50 grams of oil into 1.5 liters of 95 gasoline.

For lawn mowers, you should use only AI-92 gasoline. The proportion is 1 liter of gasoline and 40 grams of oil for two-stroke engines. First you need to mix gasoline with oil and pour it into the fuel tank. Changing the oil in a Honda lawn mower. If you do not mix gasoline with oil, but first add gasoline then oil, the lawn mower will not work and the piston mower will burn out.

Usually upon purchase lawn mowers Attached is an instruction manual that clearly describes the fuel requirements. However, the instructions are not always saved. To refuel a lawn mower in order to extend its service life, you need to add oil to the gasoline. This is usually done in proportions of 1 to 40, that is, for 40 liters of gasoline take 1 liter of oil. Changing the oil in a lawn mower briggs stratton. If you reduce the amount of gasoline to 1 liter, it turns out that 25 ml of oil is needed. Before refueling the lawn mower, this mixture must be thoroughly mixed in a separate canister, and only then poured into the gas tank.

Preparation of fuel mixture for two-stroke engines

The video shows how to make a fuel mixture for two-stroke engines. Refueling mowers, chainsaws, etc.

Typically, manufacturers write in the instructions that gasoline must have an octane rating of at least 90. Changing the oil in a Viking lawn mower engine. As for the proportion of oil and gasoline, then, again, you need to look at the instructions. For one saw 1 in 30, for others - 1 in 40, and, for example, for Husqvarna chainsaws 1 in 50.

Dilute 50 ml of two-stroke engine oil per liter of gasoline. internal combustion- you can't go wrong. Petrol it is better to use brands AI 93 or AI 95. Changing the oil on an alco lawn mower. Trimmer gasoline service changing engine oil. Well, the exact proportion and brand of gasoline must be indicated in the passport attached to the product

Take the instructions for the lawn mower, usually this is the booklet with which you bought the lawn mower. It will definitely indicate what the requirements for gasoline are. Changing the oil in a lawn mower mtd. Usually you need to fill the ratio 1:40, although 1:30 is possible. That is, 1 part oil and 40 parts gasoline. The ratio is also indicated on the oil packages. We buy 92 gasoline, mix it with oil in a separate canister, and then fill the lawn mower and chainsaw with this mixture.

Most often, for two-stroke engines in petrol mowers AI-92 gasoline is used, and the oil to gasoline ratio is 1:40. But if you are not sure, you can try 1k30. And then watch how the braid behaves and adjust it in one direction or another.

Petrol mowers typically use a 2-stroke engine. Accordingly, it is necessary to use the fuel mixture on which the 2-stroke engine runs. Change of oil in the trimmer gearbox. Since the engine does not have a lubrication system, oil is added to the fuel. If oil is not added to the fuel, the engine will very quickly fail due to the fact that the rubbing parts run dry and overheat. The piston is the first to suffer piston rings and a cylinder. Recently, almost all manufacturers recommend using gasoline with an octane rating of at least 92 with oil for 2-stroke engines in a ratio of 40:1. If the engine is new or after overhaul, then you can add a little more oil during the break-in period (25:1). In any case, if the manufacturer's recommendations are unknown, it is better to look at the label of the can of oil. Makita lawn mower oil change. If there is a question about changing the proportion, then it is better to give more oil. In this case, the risk of engine failure will be minimal.

Please note that you also need special oil for a 2- or 4-stroke engine, and those for lawn mowers contain special additives.

Lawn care equipment takes pride of place in the garage country house or dachas. Competitors - a walk-behind tractor or a chainsaw - are losing to trimmers and lawn mowers in popularity. Maintenance operations for brush cutters include maintaining cleanliness, maintenance and regular refueling.

Using a trimmer in the garden

IN modern conditions The purpose of the trimmer is to care for the lawn and the area as a whole. Compared to a traditional lawn mowing unit, the trimmer has some advantageous differences:

High mobility. This allows you to use the device in hard-to-reach and limited-space places.

Versatility. Depending on the type of vegetation, the working parts change, which allows you to cut grass of any height and hardness.

Simplicity of design. With timely maintenance, the trimmer does not require regular adjustments or frequent repairs.

When choosing a trimmer, analyze the operating conditions of the unit, which will help to produce correct selection by engine type and power.

How many types of engine are there?

When choosing a trimmer based on the type of motor, you should consider some features. Units with electrical units have significant limitations related to providing power to the motor. Diesel engines, as on walk-behind tractors, taking into account low speeds, they are not offered for trimmers.

WATCH THE VIDEO

Consider the features of the gasoline engines used:

Two-stroke cycle. Structurally it is simpler. When servicing, they are demanding on the quality of the working mixture - any deviations lead to a reduction in engine life.

Four-stroke cycle.
There is no need to maintain a precise ratio of gasoline and oil for a lawn mower - mixture formation occurs automatically, and the working fluids are in two various containers. The product turns out to be more expensive, but it is quieter, and traffic fumes– cleaner.

Regardless of the type selected gasoline engine the selection of oil and gasoline is carried out strictly in accordance with the recommendations of individual manufacturers.

Selecting gasoline and oil for refueling

In the vast majority of cases, gasoline with an octane rating of 92 is used to fill the trimmer’s gas tank.

But if the manufacturer specifies 95 gasoline for the trimmer, then it’s not worth saving. The price difference between the two varieties is currently minimal.

You should be careful when selecting oil. API classification gives a certain order for fluids of two-stroke engines:

class TA - air-cooled engines - from mopeds to lawn mowers;

TV class - low-power engines up to 200 cm3 from chainsaws to light motorcycles;

vehicle class – motorcycles and snowmobiles;

class TD – for use with motors of yachts, boats and hydroscooters.

Therefore, oils from the last two categories are not allowed for use with trimmers. When purchasing oils from domestic sellers, pay attention to the method of mixing the liquid with gasoline. When marked “self mix” - not required additional conditions to mix the two components. When marked “pre mix”, forced mixing is required.

Do not ignore the recommendations to use only recommended oils. Professionals such as Stihl and Husqvarna develop original recipes for their models, taking into account their temperature conditions work, parts used. You should not deprive yourself of the warranty in advance by saving on oil.

Practical guide for correct preparation of the mixture

Before deciding how to mix oil and gasoline for a trimmer, you should complete organizational issues. This includes the following points:

Storage technical fluids. For gasoline, it is better to provide a metal canister, and leave the oil in the original container. For convenience, it is allowed to use a special two-section canister.

Volume of prepared mixture. Do not prepare a large amount in advance. Better gasoline pour into the trimmer taking into account the planned amount of work. The homogeneity of the mixture will be impaired during long-term storage.

Tool for preparing the mixture. The ideal device for oil selection and dosage accuracy is an analogue of a medical syringe. This will not only allow you to accurately measure the liquid, but also make it convenient to use.

By the way, when buying oil, do not make a large supply. It is enough to buy the amount that you can spend during the season.

We dilute in the correct proportion

The problem of how much oil to pour into gasoline for a trimmer is aggravated by bringing different proportions in different sources. For example, the following discrepancy is often encountered:

the proportion of 1:40 is indicated in the instructions for the unit;

value 1:25 on the plastic container of the fuel tank;

proportion 1:50 in a plastic container for preparing the solution.

If you have the slightest doubt, pay attention to the packaging of the oil. When determining the volume of oil to be poured into gasoline for a lawn mower,
the properties of the liquid are taken into account. It is taken into account that two-stroke engines do not like oil starvation. At the same time, excessive enrichment of the mixture with oil is perceived capriciously.

When determining how much oil will need to be added to gasoline for a trimmer, use the standard proportion. For one liter of gasoline, divide 1000 ml by 50 to obtain a volume of oil measuring 20 ml. If the volume to be filled is 500 ml, then the amount of lubricant is reduced proportionally. It is easy to calculate the amount of gasoline for large volumes. If you need to prepare a mixture for a mowing team, you will need 200 ml of oil per 10 liters of gasoline.

What to add

Uniform mixing is important. Therefore, when adding oil per liter of gasoline to the trimmer, use the following algorithm. Half of the gasoline is mixed with the entire required volume of oil. After thorough mixing, adjust the volume of the mixture to the nominal volume by adding the remaining gasoline.

Keep all containers, including the mixing container or gasoline can, clean. You should not use improvised containers made of unprepared plastic to prepare the mixture. Even small portions of impurities or debris will cause carburetor failure. After preparation, it is better to pour gasoline into the trimmer using a container with a device that will protect the mixture from spilling.

If you break the ratio

The mixture supplied to the cylinders is a gasoline-oil mist. Oil helps lubricate moving parts and surfaces in the cylinder. Lack of oil affects the service life of parts. With a large proportion of oil, it does not have time to burn. Deposits form, which over time can peel off from the cylinder walls, leaving marks and wearing out the surface of the cylinder walls.

When operating, try to remember how much oil per liter of gasoline is needed for the trimmer, even with single refills. For example, when extracting the last drops of oil from a container, it is a mistake to think that a one-time violation of the proportion will not change anything.

Do I need to dilute gasoline for a 4-stroke engine?

Lubrication of parts of the cylinder-piston group in a more advanced engine is carried out using the traditional method of splashing and under pressure. Therefore, there is no need to add oil to gasoline. Just control its volume in the working tank.

The operating life of the liquid is 50 hours. For smaller jobs, follow the seasonal replacement principle. The oil must be sucked out from the oil drum.

We service a push-pull trimmer

For two-stroke engine The main maintenance operation is maintenance air filter. The frequency is 10 hours of operation. When cleaning, wash the material in warm soapy water. Before reinstalling the surface, lightly soak it in oil.

At the same time check the cleanliness fuel filter(if available). However, it is better to clean the fuel mixture when refueling the trimmer. The spark plug is checked regularly for carbon deposits. The gap between the electrodes should be 0.5 mm.
