How much oil should be poured into a trimmer for grass per liter of gasoline

Gasoline braids are fairly common tools used by owners of garden and household farms for mowing grass and hay harvesting. The more common names of the tools are the terms “trimmer for grass” and “lawn mower”. The main difference is hidden in the design of the motor. the expensive segment of the devices is equipped with four.stroke models, and cheap ones. two.stroke. The last option has advantages, including a small mass, ease of use, as well as low cost.

The most important condition for the operation of two.stroke models is the preparation of the fuel mixture, based on the proportion of gasoline and oil determined by the manufacturer. The simplified engine design does not provide a separate lubrication channel, so the engine oil is added directly to the gasoline. Violation of the correct proportion leads to a significant decrease in the resource of the tool and even to its breakdown. We will figure out which composition is required for gasoline trimmers, how to prepare the mixture correctly and what it can affect.

Selection of gasoline for a trimmer for grass

For some reason, everyone prefers to choose a brand of gasoline for motorcycles at their discretion. This is an erroneous approach, because, first of all, it is necessary to carefully study the instructions where the manufacturer’s recommendations for the choice of fuel are given. But this is also not a guarantee, since unearthly fuel can be sold under different brands (which differ in many manufacturers), which are significantly different in composition. Therefore, it is necessary to focus precisely on the main characteristics in order to choose gasoline for a certain model of a trimmer for grass.

Manufacturers of benzo-tools recommend using AI-92 gasoline brand for work, but for more expensive types you will need fuel with a higher octane number-AI-95. Any brands, in the marking of which the number 90 and less appear, is not suitable for benzos, since they lead to rapid wear. The problem develops due to unscrupulous fuel manufacturers, which are sold under the guise of 92nd a completely different brand. The following situation develops:

  • The passport for gasoline equipment has a recommendation for the use of gasoline with an octane number of at least 92;
  • The conscientious owner goes to a gas station, where the lowest price and with a clear conscience floods such a fuel in a motorcycle;
  • As a result, the service life is reduced, since often under the guise of AI-92 AI-80 and AI-76 is sold.

To avoid such a situation, you need to select one gas station, where the proven gasoline is sold (this can be determined by the reviews of regular customers). It is also important where to fill the fuel after the purchase. for this you need to use only metal containers (plastic. prohibited).

The option is preferred when it is possible to buy gasoline for a trimmer for herb specifically for garden equipment. Then you can be confident in its quality and protection against fakes.

Fuel mixture for two.stroke engines

Trammers for grass that are equipped with a two.stroke engine do not have a separate system designed to supply oil in order to lubricate the rubbing parts. For this reason, such devices should not be refueled with clean gasoline, but a mixture of fuel with engine oil. The latter should be specially designed for two.stroke engines. The use of automotive motor fluid will lead to the premature failure of the engine.

Preparation of fuel mixture for two.roll engines

Refueling the lawn mower with a two-stroke engine needs gasoline AI-92 brand. When using AI-95, engine overheating and uneven operation of the unit may be observed. Mix gasoline with butter in a ratio of 50: 1, where 50 is fuel, and 1 is oil. It turns out that 20 ml of oil will need 1 liter of fuel.

If the motor is worn or the tool works with a high load, then the proportion is 25: 1. If there is little lubrication, then on the walls of the cylinder and the surface of the piston will appear. Then the piston ring will be destroyed, as a result of which the engine will jam. An excess is not so critical, but it can lead to the formation of a carbon. The piston ring is overwhelmed, which will reduce the power of the device.

Oil and gasoline proportions for the fuel mixture

Gasoline for a four.stroke engine

Devices with a four.stroke engine have a more complex device. Oil and gasoline are poured into different containers, from where they are then supplied to the engine. For a mower with such a motor, you need gasoline of the AI-92 and AI-95 brands. Applying a fuel with a lower octane number is better not This will lead to unstable engine operation. In addition, you can not use a lubricant intended for two.stroke models.

The finished mixture of gasoline with butter can be stored for no more than 3 months (clean gasoline is stored less). Dilute the fuel in the quantity that is enough for several applications of the trimmer for the grass. In general, prepare:

How to Get Perfect Lawn Edges with a Weed Wacker

  • gasoline and oil, which is suitable for two.stroke engines with an air cooling system;
  • metal canister and a mixture container;
  • respirator;
  • gloves.
  • Pour 1 l of gasoline into a suitable volume of 1 l of gasoline and add 1/2 of the desired amount of oil.
  • Mix carefully, being at a decent distance from the sources of open fire.
  • Add the rest of the oil to combustible and mix everything again.

General recommendations for refueling a trimmer for grass with a two-or four-stroke engine:

Gasoline for the preparation of the mixture

Gasoline requirements for the preparation of the mixture are extremely high, He is its basis. The first thing that should not be done is to look for places where you can buy fuel cheaper (refueling without name, etc.D.), because in the end, all the apparent savings in several dozen can be eaten by an expensive engine repair, which is disabled by poor.quality fuel.

Using cheap gasoline with a reduced octane number, the user thereby increases the load on the unit. Its wear occurs much faster, the resource decreases, moreover, in the proportion not one to one, but much more

The second one should remember is to use only fresh gasoline for the base of the mixture. Many in the country or in the garage have fuel reserves that stand there up to six months, waiting in the wings. Fuel, evaporating, enters into a chemical reaction with the surface of the canister (especially plastic), thereby acquiring new, not at all useful properties for ICE. If gasoline stood in the canister for a month and a half, it is better to pour it into the fuel tank, where, having mixed with the total volume of more fresh gasoline, it will not cause any harm to the engine of the machine. Two.stroke ICE are more sensitive in this regard. That is why manufacturers recommend using only the highest quality fuel.

As for the octane number, there are spores of specialists, what kind of gasoline to pour into a trimmer for the grass, they still do not subside. Most manufacturers recommend pouring a high-octane gasoline of the 92nd brand into the fuel system in the fuel system. True, there is one small reservation, quite often the instructions indicate the wording of “not lower than the 92nd”, and this leaves the space for guesses, which gasoline to use.

Of course, the performance (efficiency) of 95th gasoline is slightly higher than that of the 92nd. The latter, in turn, is the heir to the Soviet 80th, on which many equipment worked. But having higher energy efficiency, the 95th is fraught with some features. For example, it is more suitable for modern car models, while ICEs installed in garden equipment are far from some constructive innovations, their structure remains practically unchanged for decades. For a two-stroke gasoline engine installed in most modern trimmers, it will be enough to fill in gasoline of the 92nd brand, purchased on a proven refueling network.

It is best to look for options without additives with the markings “Eco”, “Ecto”, For clear work, you need a clean gasoline base. Adds the mixture with additives.

Is 95 gasoline is needed for optimal work, the question is rather a philosophical, and there is no specific answer for it. It is enough to remember that in the tortures and recommendations it is rare quite rarely, and this already says a lot. In addition, they are poured, usually, at their own peril and risk, wanting to improve the characteristics. If for the sake of the experiment you want to change the 92nd gasoline to the 95th, it is important to remember the consequences in the form of increased wear, unstable operation of the power unit and fails of its individual nodes. Of course, none of the above may occur, but the probability, in the event of the admission limits, is extremely increasing.

Obtaining a mixture

How much oil is pouring per liter to get high.quality gasoline mixture? It would seem that there is nothing complicated in mixing two substances. The preparation of the mixture is often complicated by the fact that in various sources, various information is indicated. For example, the instructions indicate the proportion of 1 to 40, on the fuel tank of the trimmer for grass 1 to 25, and on the canister with oil 1 to 50.

Most experts are sure that it is necessary to mix in accordance with the instructions indicated on the packaging with oil.

There are a number of requirements for how to dilute. Do not add too much oil. This leads to a decrease in ignition characteristics. As a result, the devaluation of the efficiency of the power unit occurs, and the general decrease in its resource. In case of oversaturation of gasoline mixture with oil, soot sediments (ventilation windows of the cylinder) will form on the inner surface of the walls of the engine. This is fraught with the formation of a nap on the piston.

Neither oil starvation, nor excess lubricant on a gasoline basis are a good basis for prolonged ICE operation. For a prolonged operation, the same number of components is necessary. Breeding is best done using the same measured tools to exclude unnecessary errors.

How to calculate, let’s say how much oil is pouring per 1 liter of gasoline with a required ratio of 1 to 50? To do this, we transfer the volume of gasoline into milliliters 1l = 1000 ml. Accordingly, to achieve a ratio of 1 to 50 thousand, they are divided into fifty. Only 20 g of oil will need one liter of gasoline. Someone measures the oil with a 20 cubic syringe, but for such purposes there is a special measured spoon, which sometimes comes with oil from some manufacturers.

For ease of calculating the ratio of oil and gasoline, we bring the table https: //

Learning to dilute gasoline with oil for a trimmer for grass if you do not have or pour oil

If you bought a trimmer for grass, a lawn mower, a motorcycle, a chainsaw and other types of equipment, then you probably know that two.stroke engines are used as power units on them. These motors do not work on pure gasoline, like four.stroke, but on a mixture of gasoline with butter. In what proportion should be diluted gasoline with oil for a trimmer for grass. this question asks for himself every summer resident before preparing the tool for work. We will figure out in detail in this matter, since the dilution of gasoline with oil for a trimmer for grass affects the life of the tool, and improper preparation of the mixture will lead to rapid engine wear. What is the dangerous or insufficient amount of oil in gasoline for a trimmer for grass:

  • If gasoline is diluted with a large amount of oil (above the norm), this will lead not only to a large amount of smoke, but also to the formation of a carbon on the walls of the cylinder and a drop in power. This incapacitance will cause wear of the piston, which will be diagnosed to reduce its performance
  • If gasoline contains an insufficient amount of oil poured into a trimmer for grass, then this is even more dangerous. After all, the working mechanisms of the engine will not be lubricated in sufficient quantities, which will ultimately lead to their rapid wear (rapid destruction of the piston rings and jamming of the motor occurs). With an insufficient amount of oil in gasoline, poured into a trimmer for grass, the wear of the motor will occur ten times faster

So that you do not have to pay for errors at the cost of overhaul of the engine or buying a new tool, it is necessary to fill the fuel of the correct consistency into the tank from the first day. You can find out the ratio in the instructions for the tool, since models of different manufacturers can give different recommendations. Usually this ratio is the following norms:

  • 1 to 25 or 1 liter of gasoline 40 grams of two.stroke oil
  • 1 to 40 or 1 liter of gasoline 25-30 grams of grease
  • 1 to 50. this is added to a liter of gasoline 20 grams of oil

The value of 1 to 50 is considered standard (indicated on canister with butter for two.stroke engines), but it is necessary to rely on it in the most extreme case, since the manufacturers indicate the recommended value of the proportion, and if it is not observed, the operational resource of a two.stroke motor decreases.

In addition to observing the proportion, you must also learn to prepare the mixture. After all, the option of adding oil to the gas tank is categorically contraindicated, although some do so. If you bought a trimmer for grass or a lawn mower, you will need the consumables that you will use to prepare the mixture. Instructions for the preparation of the fuel mixture in a trimmer for grass have the following view:

  • Prepare gasoline and two.stroke oil, based on the above recommendations for choosing a lubricant and fuel
  • Additionally, to prepare the mixture, you need to take a container or container. Typically, a plastic bottle is used for this, the choice of which needs an appropriate approach. It should be clean inside. Using a milk container and other drinks is not recommended. The best option is a mineral water container
  • It is very important that the capacity has a whole value of volume, that is, 1 or 2 liters, so that you do not have to calculate how much oil is pouring into a bottle per 1.5 liters, 1.3 or 1.25 liters, because you can easily make a mistake so easily
  • You will also need a syringe that is used as a measured device for dosing. For such purposes, a regular medical syringe for 10 cubes is suitable. It is desirable that the syringe has an exact measuring scale
  • After preparing the necessary materials, you can proceed to prepare

Instructions for the preparation of the fuel mixture in the lawn mower:

  • First you should fill a plastic container. The container is filled with 2 fingers not supplemented to fit the oil
  • The required amount of two.stroke oil is typed in a syringe, and poured into a bottle with gasoline. You need to do just that, and not vice versa
  • After adding a lubricant to the bottle, it requires to close it tightly with a lid and stir. However, take into account that the streaming needs oil with the designation “Pre mix”. If the container “Self mix” is on the container with oil, then you do not need to shake the container, and after connecting the substances, you can pour them into the tool tank

After preparing a fuel mixture for a trimmer for grass, it remains to season the tool, and start work. How to correctly refuel trimmers for grass, lawn mowers, chainsaws and other types of motorcycles, consider in detail.

How to fill in the finished fuel on a two.stroke motor

Many do not comply with some important recommendations for pouring fuel in the gas tank of the trimmer for grass or lawn mowing, which ultimately leads to unpleasant consequences. Consider important recommendations on how to properly fill in the gas tank of motorcycles diluted fuel from gasoline and oil:

  • Prepare a funnel or watering can. Despite the large diameter of the hole of the gas tank, very often when trying to get into it, a certain part of the fuel is spilled, which enters the tool case. The fuel that came to the instrument can cause ignition when heated, so it is very important to use a funnel or a watering can
  • Before twisting the cork, you should thoroughly clean the surface of the tank, since pollution can get inside, which will cause a quick clogging of the benzophilter
  • Work on pouring fuel must be carried out in calm weather or in a secluded place in order to exclude the likelihood of dust and small grains of sand inside the tank
  • Do not leave the open hatch of the tank for a long time, since not only small grains of sand and dust can fall into it, but also insects
  • During flooding, do not inhale the vapors of gasoline, as they are dangerous for humans. When working with a trimmer, the master should use protective glasses, headphones and respirator
  • Pour fuel into the tank must be before the mark. If you pour a full tank, then with screwing the cork, some will result in a non.excessive use of fuel. In this case, it is better to shorten than to pour

Given these recommendations, you can significantly extend the service life of the gasoline tool in question.

It is interesting! Work on the preparation of the mixture and pouring fuel is also recommended in protective gloves.

Choosing oil mushrooms

For trimmers engines, it is necessary to choose oils with “2T” labeling, which are used for ICE with a volume of 50 to 200 cm and have air cooling. First of all, when buying oil, it is worth paying attention not to the price, but the protective properties of the material, since slight savings can subsequently become a real headache for the owner and, as a rule, large costs.

Two.stroke oil for lawn mower

The main factor that determines the quality of the oil for a trimmer for grass is an alkaline number. It is this component that excludes the oxidation of the rubbing parts and slows down their destruction. During operation, the oil gradually loses its alkalinity and becomes oxidized. The optimal level of acidity (pH) should not be less than 8-9 units.

The viscosity of the oil for motorcycles also has a great influence on the process of gasoline tools. This indicator determines the possibility of operating a trimmer for grass at different temperatures. For example, summer grades of lubricants thicken even with a slight drop in temperature. Due to the use of the lawn mower exclusively in the spring-autumn period, oil with summer marking will be an excellent option.

The temperature of the outbreak for a trimmer oil for grass should be more than 225C, otherwise the oil will quickly burn out, and the piston group will be subjected to intensive wear.

What to look for when choosing oil?

Modern two-stroke engines of Motokos are seasoned with a mixture of AI-92 gasoline and oil marking “2T”. The use of fuel with a higher octane number will contribute to an increase in the temperature of the flash and, as a result, burning out lubricants.

Varieties of STIHL oils

Undoubtedly, the best oil for a trimmer for grass is recommended by the manufacturer, however, the owner does not always have the opportunity to purchase precisely a “branded” lubricant. Experts recommend Shell Helix Ultra, based on PurePlus technology, which helps to improve the basic properties of lubricants.

For gasoline trimmers of the German manufacturer, STIHL must use the STIHL HP Ultra, Stihl HP, Stihl HP S oils. The budget substitute can be the products of the Vityaz company, which in its properties is the most similar to the recommended material.

The consequences of refueling with a mixture with incorrect proportions

When diluting, combustible materials are very important to observe the ratio recommended by the manufacturer Motokos. If the oils are not enough, then bulletin forms on the piston and cylinder, which sooner or later is led to breakdown of the piston ring.

Important! In addition, as a result of friction, the metal from the piston settles on the walls of the cylinder, and the engine can simply jam. This will require repair or replacement of the motor.

And with an excessive amount of oil, the piston ring is shielding, as well as the formation of soot on the piston, on the spark plug, etc.D. All this leads to strong wear of equipment and the need for constant cleaning.

The rules for filling the mixture in different engines

All of the above is relevant for two.stroke engines. In the case of four.stroke engines, dilute and mix nothing. gasoline is poured into the fuel tank, and oil. into the crankcase. It is important to know that you can not add oil intended for a four.stroke engine or for a liquid cooling system with a two.stroke engine. Otherwise, the entire piston system will be disabled or a strong overheating will occur.

Important! For the first refueling of the four.stroke engine, the oil in a special tank can be poured no more than 90 ml.

What gasoline to fill

Gasoline for a trimmer for grass must be selected unhealthy with an equal number of 92 or 95. As practice shows, AI-80 gasoline can lead to breakdowns of the device, which is a dubious savings.

The fuel should be fresh, that is, after buying it can be stored for no more than 60 days.

Other factors are affected by the quality of fuel, for example, the use of a special lubricant for the lawn mower and its breeding in a separate container. It is also recommended to use special canists designed to store gasoline.

Oil selection rules

Motor oil depending on the chemical composition:

  • mineral. made of oil distillates and is intended for low.power air.cooled equipment;
  • semi.synthetic. is a mixture of mineral and synthetic oils and is suitable for 2T and 4T, as well as for air and liquid cooling;
  • synthetic. produced on the basis of complex ethers and can be used in powerful equipment, as well as for work in difficult climatic conditions.

Important! Oils for two.stroke and four.stroke engines differ among themselves the ability to dissolve, burn and evaporate. At the same time, so that liquid lubricant differs from gasoline, it is painted in different colors: blue, green, red.

Depending on the classification of the API, the following groups of oils for trimmer engines can be distinguished:

  • That. for low.power equipment with an engine volume up to 50 cm³ and air cooling;
  • TV-for powerful equipment with a motor volume of 50-200 cm³ and an air cooling system;
  • TS. for a powerful two.stroke equipment (motorcycles, chainsaws, lawn mowers, etc.) with a engine volume 50-200 cm³;
  • TD. for motors of boats with liquid cooling.

To choose the optimal oil for a specific trimmer model for grass, it is better to take into account the recommendations specified in the instructions. For motos 2t, API-TV class oil and API-TS is usually used.

On a note! In addition, there is a JASO classification for two.stroke engines, and SAE30 is also used for four.strokes.

Leading manufacturers of garden equipment themselves develop and produce oils for their equipment. Such lubricants most fully satisfy all the technical and operational characteristics of specific series of trimmers. For example, for STIHL (STIHL) FS 5 motorcycles, it is best to use the STIHL HP or Stihl HP Super oil, for Husqvarna 143R, Husqvarna HP or Husqvarna LS oil is suitable. But the usual M-8V mineral oil is also suitable for the Patriot brand.

Calculation of the proportion of gasoline and oil for two.stroke engines

Everyone knows that two-stroke engines work on a gasoline mixture. Therefore, it is important to comply with the recommended proportions specified in the processport of the product. Otherwise, an expensive garden tool will fail. We have made a convenient calculation that will help you easily get the necessary data.

We select gasoline and oil for refueling

In the overwhelming number of cases for refueling the gas tank trimmer for grass, gasoline with an octane number 92 is used.

But if the manufacturer indicates the 95th gasoline for a trimmer for grass, then you should not save. The difference in price between two varieties is currently minimal.

The selection of oil should be taken carefully. API classification gives a certain order for liquids of two.stroke engines:

Thus, the oil of the last two categories is not allowed for use with trimmers. When purchasing oils from domestic sellers, we pay attention to the method of mixing fluid with gasoline. When the Self Mix marks. no additional conditions are required to mix two components. At the mark “Pre mix”. forced mixing is necessary.

Do not ignore recommendations for the use of only recommended oils. Professionals such as Stihl and Husqvarna develop original recipes for their models, taking into account their temperature modes of operation, parts used. Do not deprive yourself in advance, saving in oil.

Practical guide for the correct preparation of the mixture

Before solving the issue of how to mix oil with gasoline for a trimmer for grass, organizational issues should be completed. These include the following points:

much, needed, motorcycle, using

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

The volume of the cooked mixture. Do not cook in advance a large volume. It is better to pour gasoline into a lawn mower taking into account the planned volume of work. The uniformity of the mixture during long.term storage will be violated.

Mixture tool. An ideal device for the selection of oil and dosage accuracy is an analogue of a medical syringe. This will not only allow you to accurately measure the liquid, but also creates conveniently in work.

By the way, when buying oil, do not make a big stock. It is enough to buy the volume that you can spend per season.

Dilute in the correct proportion

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

At the slightest doubt, pay attention to the packaging with oil. When determining the volume that is to pour oil into gasoline for the 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. the excessive enrichment of the mixture oil is capricious.

When determining how much you need to add oil to gasoline for a trimmer for grass, use a standard proportion. For one liter of gasoline, 1000 ml is divided into 50, and a 20 ml of oil is obtained. If the poured volume is 500 ml, then the amount of lubrication is reduced in proportion to. It is easy to calculate the amount of gasoline for large volumes. If it is necessary to prepare a mixture for the Kostsov brigade, you will need 200 ml of oil per 10 liters of gasoline.

Why add

Important is the uniformity of mixing. Therefore, when adding oil to a liter of gasoline to a trimmer for grass, the following algorithm is used. Half of gasoline is mixed with all the required oil volume. After thorough mixing, the volume of the mixture is brought to the nominal with the addition of the residual part of the gasoline.

Follow the cleanliness of the container, including the mixing container or a canine with gasoline. You should not use an improvised container of unprepared plastic for the preparation of a mixture. Even small portions of impurities or garbage will contribute to the failure of the carburetor. After preparation, pour gasoline into a trimmer for grass is better with a container with a device that protects the mixture from the strait.

If you break the ratio

The mixture supplied to the cylinders is represented by gasoline-oil fog. Oil promotes lubrication of moving parts and surfaces in the cylinder. The lack of oil affects the resource of parts. With a large share of oil, it does not have time to burn. Deposits are formed, which over time are able to exfoliate from the walls of the cylinder, and leave the bully, wear out the surface of the cylinder walls.
