How to dilute gasoline with oil for a trimmer for refueling

Two-stroke tool engines operate due to a gasoline mixture that is prepared in the proportions indicated in the technical passport of the device. If you ignore mixing rules, a garden tool can quickly fail.

The functioning of a two.stroke installation differs from the operation of four.stroke engines: the grease of the rubbing surfaces in the crankshaft and other parts of the device is not from the crankcase, but by means of oil, which was previously divided by gasoline. For two.stroke engines, the general rule of preparing a combustible mixture is valid. gasoline is diluted with a certain volume of oil intended for this purpose.

How to dilute gasoline with oil for a trimmer for grass. step.by.step instructions

Fuel mixing occurs taking into account special proportions.

If you dilute the fuel mixture with an insufficient amount of lubricant, this will lead to the rapid wear of the parts of the lawn mower

The optimal ratio of oil and gasoline can be viewed in the instructions for the trimmer. As a rule, it is equal to 1:50, 1:40 or 1:25.

It will be forbidden to dilute gasoline with a lubricant component in a suitable container: to do this immediately in the fuel tank is prohibited. If you ignore this rule, the work of the motor can be unstable, as a result of which the tool will quickly fail. To dilute the fuel mixture, do not use plastic canists or bottles, since gasoline is able to dissolve this synthetic material. Fuel mixing order:

• Pour a liter of gasoline into the container (optimally. metal canister).
• Add half the necessary oil proportion.
• Mix the liquid thoroughly, away from sources of open fire.
• Pour the rest of the lubricant into the container and mix the mixture again.
• Pour fuel into the fuel tank of a trimmer for grass.

Work should be carried out by wearing a respirator and rubber gloves. For the convenience of transfusion, you can use the watering can. The finished mixture should not be stored for more than 3 months, it is better to dilute exactly as many fuel as you need for the work planned in the near future. Mnight mixing oil with gasoline, be sure to choose high.quality, buy it better at proven gas stations.

Proportions of oils and fuel

Calculation of the ratio of ingredients for preparing a gas station for grass should take place taking into account the recommendations on the packaging from oil. The standard proportion is 1:50. Any quality oil for two.stroke engines is allowed to use.

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 worth.to. 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:

• 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, t.to. 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”, t.to. 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 trouble.free 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.

The order of use and function of the oil in a two.stroke engine

To work with a 2-stroke benzotrimer, first you need to prepare a fuel and lubricant mixture. It is gasoline (usually manufacturers recommend using A-92 gasoline for this) with the addition of special oil in a certain ratio. You can find out accurate proportions from the instructions of the manufacturer of the equipment.

Oil manufacturers often also indicate proportions in which the oil must be added to gasoline.

Entering the fuel in the engine cylinder, the oil is lubricating the rubbing parts and burns during the working cycle. Wheelled gases with combustion products are thrown into the atmosphere.

Oil for two.stroke engines performs not only lubricants. It should protect the details from the formation of corrosion, bullying piston, the formation of a carbon on a candle and performs detergents.

One of the main requirements for the fuel and lubricant mixture is its complete combustion in the cylinder.

If the oil is added in an excess ratio, then complete combustion does not occur, which leads to the formation of soil and harmful exhaust. If the mixture, on the contrary, is too poor, then it will not be able to fully make the lubrication and protection of the engine. This will negatively affect the service life of a trimmer for grass.

For breeding and storing the combustible mixture, it is advisable to use metal containers, glass dishes or special containers for fuel and lubricants. Normal plastic and polyethylene partially decompose in gasoline and reduces the quality of fuel.

For work, it is recommended to use a freshly prepared mixture.

How to choose the right oil

When choosing a lubricant for motorcycles in the first place, it is recommended to follow the recommendations specified in the operating instructions.

So, for example, for the use of STIHL gasoline trimmers, the manufacturer advises using the branded oil of the same name, which fully takes into account all the features and operational modes of the power unit.

If it is not possible to buy recommended oil, then you should take products with similar operational characteristics. At the same time, it is better to opt for fluids of known brands. In principle, the oil of any manufacturer, designed for two.stroke engines, will work well in a benzotrimer.

As in the case of any demanded goods, the possibility of purchasing a fake or expired product is not excluded. Therefore, you should carefully examine the packaging. The label should be typographic quality, and the shelf life is unexpected.

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

How to choose for lawn mower?

For two-stroke engines, motorcycles use gasoline AI-92 or AI-95 grades. Most often the first of the named. This is necessarily available in the technical passport of the product. If, for some reason, it is not known exactly what gasoline the trimmer for the grass should work, you can choose by testing both grades of gasoline in action. Global changes in the engine will not happen from this, but to determine which gasoline this or that model of the unit “loves” more, according to some factors, it is quite possible. This will be shown both developed power, acceptance, and heating the engine, as well as its stable operation at all speeds.

But with the proportions of the oil to a certain volume of gasoline, it is much more difficult to determine. In this case, at least you need to know about the manufacturer of equipment. And already for standard proportions for this manufacturer, choose a proportion for a specific model, taking into account the type of oil.

You can start selection even in the country of production.

For example, for Chinese low.power trimmers, two ratios are mainly used. 1: 25 or 1: 32. The first is for minerals, and the second is for synthetic oils. We have already said previously about the choice of standard proportions for the gasosos of European and American manufacturers in connection with the type of oil. In the class of oils for household trimmers, you need to use TV oil according to the API classification. For more powerful. CU class.

About what the ratio of gasoline and oil is necessary for the lawn mower, watch in the next video.

How much oil is required to add to gasoline?

Types of oils used for breeding in gasoline

There are no oil pumps in the chainsaws, so the combustible mixture alone cannot be used. Carefully read the instruction that is attached to the manufacturer to each product. A lot of information on the Internet, finding it is not difficult.

If the lubricant is absent, then the saw after a short time will fail. It is recommended to make preventive maintenance of the unit, pour properly diluted fuel, in which case the tool will operate for many years.

Carefully read the recommendations from the manufacturer (see. “Instruction”), it is always signed there in detail: which composition is required for the power plant. It is not worth saving in oil, the benefit is small, and the engine resource can be significantly reduced. The repair of the tool is expensive, up to 85% of its cost.

If we take, for example, the Husqvarna chainsaw, then unhealthy gasoline with the first additive of the brand 92 is suitable. If the composition has a greenish kner, then this suggests that the product is a premium class. AI-92 is an optimal product that can be suitable for such a device. On average, professionals advise adding one liter from twenty to 50 ml of machine oil. If the power of the unit is one and a half kilowatts, then only 25-27 ml of oil will be required.

Opinion of expert Kuznetsov Vasily Stepanovich

If the tool is more powerful, then about 30 ml of oil is required, and in some cases even more.

How to dilute machine oil and gasoline, in what proportions? This question arises for all users. First you should stock up on containers:

The process of mixing oil and gasoline is technologically simple

It is important to observe safety precautions so that static electricity does not accumulate, not a drop of water does not fall into the fuel

Types of oils used for breeding in gasoline

What proportions should be done? Engines are mainly two.stroke, so the mixture is usually 1:50. Production chainsaws function with the products of such brands:

For foreign analogues, it is permissible to use two liters of gasoline per 80 grams of oil. Foreign saws are characterized by economical fuel consumption, oil proportions in them vary from 40 to 49 shares.

Shades of oil can vary significantly, this should be taken into account during operation. For example, the company “NR” produces machine oil of reddish ring. If the composition has a greenish (sometimes blue) shade, then this is a sure sign that the product is a synthetic premium class. The quality of such compounds is high, the cost is also rather big.

Proportions and mixing process

How to determine proportions for mixing oil with gasoline? Standard proportions should be indicated on containers with oil. The amount of oil used may differ depending on the manufacturer, however, 1:40 or 1:50 proportions are often used. A slight deviation from such a ratio is allowed. this will not entail serious consequences.

Having determined the exact proportions, you need to proceed to the direct preparation of the mixture. What can this be done? Various containers are suitable for this

Important: in no case can you mix fuel with butter directly in the gas tank, pouring one liquid after another in turn. the mixture is always prepared separately and only then slowly poured into the gas tank

For mixing, you can use a variety of devices, among which:

Gas and oil proportions

You need to choose the solution, taking into account the recommendations from the manufacturer of the braid for the grass. As a rule, for a trimmer for grass, AI-92 gasoline brand is used. If the instruction indicates the 95th, then it is necessary to dilute this and without unnecessary savings (you should not take below the 92nd). Oil for two.stroke engines varies in the classification of the API. It is worth paying attention to only two types:

• Ta. for air.cooled engines (suitable for lawn mowers).
• TB. for low.power engines up to 200 cm³ (designed for chainsaws and small motorcycles).

Other categories (for snowmobiles, boats, etc.P.) are not used in trimmers for mowing grass. Having bought a product, you need to pay attention to the packaging. Domestic manufacturers have a note there regarding mixing with fuel:

The following table of recommended volumes shows how many milliliters of lubricant fluid will be required for one or another amount of motor fuel, taking into account the required proportions:

How to mix components

Preparation for the dilution of gasoline

The exact proportion is indicated in the technical characteristics (you need to strictly follow it). If vague values ​​are indicated, for example, from 1:20 to 1:40, this product has low quality and it is better not to use it. If in the instructions for a benzoca, on a fuel tank, on a bottle with a lubricant, etc.D. The numbers diverge, take into account the ratio indicated on the container with oil. But it is better to immediately use the lubricant that a specific braid for grass requires.

Mixing rules

To prepare the fuel mixture, it is necessary to use clean and dry containers, which does not contain extraneous inclusions or pollution. It is not recommended to use plastic containers. After adding liquids in the required proportion, the mixture must be thoroughly mixed for 2-3 minutes. You cannot do the following:

• Add a small amount of oil directly to the gas tank of motorcycles, as this will not give a homogeneous mixture;
• First of all, pour oil, and then gasoline. Due to the difference in densities, with this order of adding components, a heterogeneous mixture is also obtained
• Anging the components “by eye”. With this approach, it is not possible to achieve an accurate proportion of gasoline and oil for a trimmer for grass 1/50 or 1/40;
• Use polyethylene bottles, since the latter is dissolved by gasoline.

The rules for storing the mixture

For the remaining unused fuel mixture, a dark, dry corner is needed, where it can be up to 2 months. In general, there are different opinions of experts in this regard:

• For mineral oils, the expiration date is 7-10 days, after which their lubricants are lost;
• For semi.synthetic and synthetic brands there is data that they are stored from 30 days to 2 months.

After a longer period, fuel is recommended to be changed to a more fresh and new.

So, above the process was described in detail on how to properly breed a gas mixture for two.stroke engines Motokos. To avoid the breakdowns of a trimmer for grass as a result of insufficient oil or frequent purges and unstable operation due to an excess of lubricant, you should carefully read the instructions for the operation of the lawn mower and is meticulously follow it.

Step.by.step instructions for breeding fuel mixture

The optimal ratio of oil and gasoline can be viewed in the instructions for the trimmer. As a rule, it is equal to 1:50, 1:40 or 1:25 (for strongly worn engines). A measured container with a milliliter scale or a syringe of a large volume will help to observe the proportion.

It is necessary to dilute gasoline with butter in a suitable container (preferably metal or dense plastic). Special canists with a double neck are convenient to use to get a mixture. Should work in a respirator and gloves.

It is impossible to fill the oil immediately into the fuel tank, since in this way it will not work to mix liquids qualitatively. If you ignore this rule, malfunctions of the engine appear, as a result of which the tool will quickly fail.

• Pour 1 liter of gasoline into containers
• Add half the required portion of the oil
• Mix the liquid thoroughly away from the sources of open fire
• Pour the rest of the oil into the container and mix everything again

When breeding the mixture, clearly observe the proportions. Excessive amount of oil in gasoline leads to the appearance of soot on pistons and spark plugs. In case of lack of lubrication on the walls of the cylinders and pistons, bullying forms, as a result of which piston rings are destroyed, and the engine can jam.

Recommendations for pouring and storing the mixture

Before opening the fuel tank, it is necessary to carefully clean its surface, especially near the lid. If this is not done, pollution can get inside, which will cause a quick clogging of the gasophiller.

Pour a certain amount of oil-banding mixture-to a special mark on the tank. If you overwhelm it, the liquid can fall into the intake pipe and the fuel filter, which will cause fuel ignition and engine failure.

In order not to spill the fuel mixture, it is better to use a watering can or a funnel. Random drops and traces of fluid must be wiped immediately.

The operation of a trimmer for grass can begin after a canister with fuel is removed in a safe place (optimally. at a distance of at least 10 meters).

With a prolonged pause between the use of a benzoice, it is recommended to drain the remaining fuel from the tank, since under the influence of high temperatures the fuel mixture forms deposits on the walls of the ring channels. This leads to a decrease in the compression and engine power.

The finished mixture should not be stored for more than 3 months, it is better to breed exactly as many fuel as necessary for the planned work. If the liquid still remains, you need to keep it in a tightly closed metal container, exclude its contact with moisture and air. The container should be stored away from sunlight and sources of fire.
