Mixing Ratio Of Gasoline With Trimmer Oil

Fuel mixture preparation rules

The process of preparing the fuel mixture should begin with a detailed acquaintance with the instructions attached to it. As mentioned at the beginning of the article, some drivers who, in their opinion, have incredible experience, do everything “by eye”. Of course, over time, each driver knows how and what to do, however, each mixture has its own differences, so it will never be superfluous to get acquainted with the advice from the manufacturer.

The main rules for operating the fuel mixture include:

  • Do NOT under any circumstances reduce the proportion of oil to gasoline. Oil is an expensive component, so many people decide to save on it. However, an insufficient amount of oil in the mixture leads to strong heating of the piston and cylinder of the engine. Because of this, seizures appear, which ultimately leads to the need for serious repairs.
  • DO NOT use too much oil in relation to gasoline. Increasing the proportions of the oil is also detrimental to engine performance. An excessive amount of oil leads to an increase in carbon deposits and rapid wear of the engine mechanism. Repair in this case will cost as much as in the first case.
  • Do not store the prepared mixture for more than 30 days. Otherwise, it loses its properties and the use of such a mixture can harm the engine.
  • Do not allow dirt, dust and second mechanical debris to enter, due to which the engine may become unusable.

How and what to store the finished mixture?

Manufacturers recommend storing the fuel mixture in a clean container, preferably in a metal container. In no case should the mixture be left in direct sunlight, because this will lead not only to the loss of its properties, but also to other very unpleasant consequences. The maximum shelf life of the finished mixture is 30 days.

Mixing Ratio Of Gasoline With Trimmer Oil

Depending on how often the car is used, some drivers prepare the mixture once a week, others once a month. Of course, NOT every owner has the time to constantly measure the proportions and mix fuel with oil. It is important to remember that the fresher the mixture, the better it is for the engine.

Many people use plastic cans and bottles as containers for storing the mixture. It is convenient and practical. There is always room for a small plastic bottle. However, you should be careful in this. The fact is that during long-term storage in a plastic container, the fuel mixture can literally “eat through” a hole in it. The process of corroding plastic is very fast. Therefore, it is best to use metal containers.

Perhaps it is not so convenient, but it is more reliable. If, nevertheless, there is a need to use a plastic canister, then remember that you can store the mixture in it for no more than two to three days. Then it needs to be poured into another container.

Fuel and oil for mixing

It is not always easy to properly prepare the fuel mixture. It is necessary to correctly calculate the proportions, mix the liquids and store the finished mixture correctly. Some drivers use their own recipes, add their own “secret” ingredients, which may even include soda. To prepare the fuel mixture was not a problem, you need to follow a few simple rules and follow the instructions from the manufacturer.

To prepare the mixture, use standard gasoline and oil from various manufacturers. What brand of gasoline should I use to prepare the oil mixture? Some people mistakenly believe that 80-grade gasoline is best suited, because it contains many different additives. This is partly true, but it does nothing better than gasoline 92nd and 95th brands.

over, it is very difficult to get gasoline of the 80th grade, because not one large fuel producer in the country now produces Ego. Therefore, the best option is gasoline of the 95th brand, which has almost the same cost as gasoline of the 92nd brand.

What is the best oil for mixing? It all depends on the driver’s preferences in a particular manufacturer. The only thing is important to use oil only for its intended purpose. If oil for tractors or boats is for a car it is not worth using.

How to mix 2-stroke gasoline and oil

The ratio of oil to gasoline is the main fuel for two-stroke engines. The fuel mixture guarantees efficient operation of the engine, helps to preserve its moving parts and reduce the number of breakdowns.

Signs of misuse

Using a dirty or disproportionate mixture can lead to serious engine malfunctions. If you made a mistake when mixing. it’s okay, because the car itself will tell you about it. You just need to be attentive to some signs, among which:

  • The appearance of dirt and various deposits on the carburetor.
  • Rapid clogging of the fuel filter located in the gas tank.
  • Oxidation of the carburetor walls and loss of elasticity of the rubber diaphragm in various parts of the gas tank. This symptom manifests itself only with prolonged storage of an unsuitable mixture directly into the gas tank of a car.

Proportions and mixing process

How to determine the proportions for mixing oil with gasoline? Standard proportions To be indicated on the oil container. The amount of oil used may differ depending on the manufacturer, but proportions of 1:40 or 1:50 are often used. A slight deviation from this 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. How can this be done? Various containers are suitable for this. Important: in no case should you mix fuel and oil directly into the gas tank, pour one liquid after another in turn. the mixture is always prepared separately and only then is slowly poured into the gas tank.

A wide variety of mixing tools can be used, including:

  • Special mixing containers. These are handy canisters with two separate compartments. separate for gasoline and oil. To prepare a mixture in such a container, you just need to pour the required amount of liquid, close the container and tilt the canister several times. Such devices are very convenient, but they are also quite expensive. If you have to mix the mixture often enough, then you should think about purchasing such a container.
  • Conventional metal and plastic canisters. Standard canisters. The most practical of these. One has only to be careful when using plastic and glass canisters, because when using them, there is a possibility of an electrical discharge. If you need to prepare a small amount of the mixture, you can use a regular plastic bottle.
  • Handy means. To save money, many people use improvised devices, for example, children’s horns and even syringes. Such funds are not very convenient, but they cost a penny.

Formation of gummy deposits in the carburetor area.

At the slightest manifestation of one of the signs, it is necessary to make changes in the mixing process, choosing more suitable proportions. This way you can select the ideal fuel mixture and avoid serious engine malfunctions.

In order to independently prepare the correct fuel mixture, which will ensure ideal engine performance, you must use the correct fuel, strictly adhere to the proportions indicated by the manufacturer, use a suitable container and store the ready mixture for NOT longer than 30 days. By adhering to THESE rules, you will prepare the perfect mixture for your car engine.

Fuel mixture: the proportion of oil and gasoline for the chainsaw

The chainsaw engine is the “heart” of the tool, so it is very important to use a properly prepared fuel mixture.

The fuel mixture for a chainsaw is prepared from two components. oil and gasoline. Chainsaws are equipped with two-stroke engines, so oil is not added to the lubrication system (as in a four-stroke engine), but directly to gasoline. At the same time, it is very important to observe the correct proportions of ingredients, of course, in no case should you try to work on pure gasoline, because in this way you will very quickly “kill” the chain saw.

If we talk about what kind of gasoline to pour into the chainsaw, then it will be optimal to use fuel with an octane rating of A-95, in this case the savings on fuel can turn out to be deplorable. Often European manufacturers indicate that it is possible to use A-90 or A-92 gasoline, but in the post-Soviet countries the quality of gasoline is inferior to European, therefore, in our realities it is better to use higher quality gasoline.

See also  Gasoline For Trimmer Proportions

As for the proportion of the oil-oil mixture itself, everything is simple here: you must follow the instructions for the tool. All manufacturers of chainsaws indicate the required ratio in the instruction manual or in the passport of the tool, in addition, the proportions for refueling the chainsaw may differ depending on the model of the chain saw. As a rule, the proportion of oil and gasoline to a chainsaw of famous manufacturers is a ratio of 1:40 or 1:50, which means 1 part of oil for, for example, 40 parts of gasoline. Now arithmetic 1 liter of gasoline = 1000 ml of gasoline, divide by 40 and we get 25 ml of oil. If you do the same to a 1:50 ratio, you get 20 ml of oil per 1 liter of gasoline. As for budget chainsaws made in China, the situation is slightly different. The ratio of gasoline to chainsaw oil made in China 1:25, that is, divide 1000 ml of gasoline by 25, we get 40 ml of oil. The thing is that in branded chainsaws, a solid assembly and the distance between the pistons and cylinders in the engine is much less than in Chinese chainsaws, therefore the required amount of oil differs almost twice.

In order to measure the correct amount of oil, use a conventional medical syringe of sufficient volume.

Another subtlety. Fill the dry gas canister with gasoline first and then oil. The procedure, on the contrary, is fraught with a low quality fuel mixture, because the oil is denser, it will stick to the bottom of the canister. what a good mixing here.

Be sure to prepare the fuel mixture in the Canister and fill the ready-made special fuel into the gas tank! Never ready and DO NOT mix it directly in the fuel tank of your chainsaw!

If you figured out the question of how to breed gasoline for a chainsaw, then on storage conditions and shelf life of the fuel mixture it is worth saying a few words. It is best and easiest to prepare a petrol-oil mixture for 1 liter of gasoline, it is recommended to do this immediately before working with the tool. Chainsaw fuel tanks have a volume of 0.3 to 1 liter. In the conditions of domestic use, the entire volume of the prepared fuel mixture is rarely used in one session, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special Canister for gasoline, in a dry, dark place. It is optimal to count that the shelf life of the finished mixture will be 7-10 days. The fact is that the oil on the market now is NOT synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.

At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool will stall (so that there is a dry carburetor in the saws) and now you can leave it in the next operation session.

Unsuitable fuel mixture must be disposed of.

How much oil is needed for 1 liter of gasoline?

How much oil to add to gasoline for a two-stroke engine is not difficult to calculate.

It is enough to divide the amount of gasoline by the recommended ratio.

We will assume that a liter of gasoline is 1000 ml.

Now, to calculate how much oil to add to gasoline for the trimmer, to get a mixture of 1:50, you need to divide 1000 by 50.

In total, 1 liter of gasoline requires 20 ml of oil. It is convenient to measure the required amount of lubricant with a 20 ml disposable syringe.

Do the same with other ratios / proportions.

Instruction. Two-stroke and four-stroke

Internal combustion engines used in trim tabs come in two-stroke and four-stroke. By design, two-stroke engines are simple. But they require a high-quality fuel mixture.

A four-stroke engine does not require the correct proportion of oil and gasoline. Formation of the desired mixture is automatic. The components of the combustible mixture are stored in different containers. The fuel is expensive, but the costs are covered by the silent operation of the unit, the environmental friendliness of the exhaust gases.

Vladimirus-team. What gasoline to fill

Gasoline for the trimmer should be chosen unleaded with a stroke number of 92 or 95. As practice shows, AI-80 gasoline can lead to device breakdowns, which is a questionable economy.

Fuel must be fresh, that is, after purchase it can be stored for no more than 60 days.

Other factors also affect the quality of the fuel, such as using a special lawn mower lubricant and diluting it in a separate container. It is also recommended to use special canisters designed for storing gasoline.

In what ratio dilute gasoline with trimmer oil?

Summer residents, owners of private suburban households for lawn care, weed mowing, buy small mechanization. Preferred trimmers powered by combustion engines fill in a properly diluted mixture of gasoline and oil.

Motorized streamers require maintenance, use of a combined fuel. By keeping the ratio of gasoline to oil, it is easy to achieve the performance of lawn mowers.

Practical recommendations for preparing a mixture

Absolutely primitive options should not be considered as oil for a lawn mower, which include autolas of the AC-10 ASZp-10 brands or exotic Chinese and garage origin “masterpieces”. The bulk of lubricants for two-stroke engines are painted by manufacturers in contrasting colors of gasoline: red, green or blue. There are several recommendations proven by many years of practical operation of trimmers.

How much lubricant is required to dilute per 1 liter of fuel if the operating instructions indicate the ratio 1:40, on the fuel tank. 1:25, and on the oil canister. 1:50? The answer is unequivocal. you need to follow the recommendations given on the packaging with the lubricant. Two-stroke engines DO NOT like oil starvation, but you should not oversaturate gasoline with oil either. This provokes the formation of abundant soot deposits on the ventilation ports of the cylinder, which leads to seizure of the piston.

The proportion of how to dilute gasoline with trimmer oils is not difficult to calculate. It is enough to divide the amount of gasoline by the recommended ratio. One liter of gasoline is 1000 ml. To calculate how much lubricant you need to add to get a mixture of 1:50, you need to divide 1000 by 50.It turns out that 1 liter of fuel requires 20 ml of oil. It is convenient to measure the required amount of lubricant with a disposable syringe with a volume of 20 ml.

Do not prepare a large amount of fuel mixture in advance. Gasoline diluted with oil should be stored in a tightly closed container in a cool place. It is safer to store the prepared mixture using steel or aluminum canisters, rather than plastic containers. This is especially true of containers for drinks. Polyethylene terephthalate, which is used in their production, is NOT resistant to most oil products and additives. But plastic is great for sewer systems https://ingplast.ru/sistema-navozoudaleniya/

It should be remembered that the resource of the unit, its performance, fuel consumption and comfort when working on the lawn largely depend on how to dilute gasoline with trimmer oils.

What two-stroke engines DO NOT like?

Prepares the working mixture manually, it should be remembered that two-stroke engines DO NOT reach the design working power if the proportions of the fuel mixture are violated. The above condition forces the owner of the unit to comply with the proportions. As practice shows, the use of lawn mowers with an underfilled lubricant product. Oil starvation of the engine is observed, and does not allow the unit to be brought to the specified power.

Excess lubricant prevents the engine from developing the required power. Prepares a working mixture, a reasonable question arises, how much oil needs to be mixed in gasoline. Helps to define the exact standard. It is recommended to fill the trimmer with gasoline according to the following mathematical calculation. If the fuel tank holds 5 liters, 1 liter of gasoline is divided by 50. That is, 100 ml of lubricating consistency is poured into the gasoline for the trimmer mower per 5 liters. The owner of the lawn mower receives the ideal fuel in terms of structural composition.

Gasoline to lawn mower oil ratio

lawn mows are a fairly common technique for combating weeds in summer cottages, in road gardens and housing and communal services. These devices have two more names. trimmer and lawn mower. These units differ in their engines. The more expensive ones have four-stroke engines, all the others have two-stroke engines. Of course, the latter are the most popular among the population, since they are simpler in design, and lighter in weight, and much cheaper than their four-stroke competitors. However, two-stroke models are inconvenient in that the fuel mixture for them must be prepared manually, maintaining a strict dosage between gasoline and oil. In four-stroke analogs, the mixing of THESE components occurs automatically, you only need to fill the gas tank and oil tank with the corresponding substances. Let’s consider the issue of the correct refueling of two-stroke lawn mowers, since it depends on how effective and long the operation of such a unit will be.

Refueling the four-stroke lawn mower

Four-stroke engines are used in professional lawn mowers. They have great power and can work for a long time without interruption and refueling. They also use gasoline and oil as fuel, but they are poured into different tanks. This means that the oil does not participate in the combustion process, therefore the exhaust gases are not so toxic.

See also  How to Calculate Lawn Mower Gasoline Consumption

On a note! Along with better environmental performance and the ability to heat less, four-stroke lawn mower engines are also more economical. They consume much less fuel. savings up to 50% for gasoline and up to 80% for oil.

Features of refueling a lawn mower

Lawn mowers are divided into two-stroke and four-stroke depending on the engine design. In the first case, the piston in an internal combustion engine makes 2 strokes in one working cycle, and in the second case. 4 strokes. Differences in the principle of operation of the engine cause different approaches to refueling the trimmer.

Consequences of violation of the ratio

How accurately you will observe the proportions of the oil-gasoline mixture recommended by the manufacturer depends on the service life of the motor scooter engine. The fact is that the fuel mixture enters the cylinders in the form of gasoline-oil mist. And the task of the oil composition is to lubricate the moving and rubbing parts and surfaces of various parts in the cylinder. If it suddenly turns out that there is not enough oil, but somewhere it will not be enough at all, the parts touching dry will begin to damage each other. As a result, scuffs, scratches and chips are formed, which will certainly lead to complete or partial engine failure (for example, it can jam).

In the opposite case, when too much oil enters the engine, it does NOT have time to completely burn out, settling on the cylinder walls and turning over time into solid particles. coke, slag and the like. As you might guess, this also leads to engine failure. The most important thing is that you must not allow. even a single violation of the proportion towards the lack of oil. It is better to pour a little oil 10 times than not to top up just once. It often happens that this time is quite enough to break the engine.

How to dilute gasoline with trimmer oil

Dilute trimmer gasoline in the correct proportion. An insufficient amount of oil can lead to poor lubrication of the mower components, which contributes to rapid wear. In the event that the oil is more position, carbon deposits will form on the pistons and spark plugs. Carbon deposits on the moving parts of the engine interfere with normal operation and lead to early engine damage.

What proportion is required for a particular trimmer model can be found in the attached instructions. Most often, for 2-stroke gasoline engines of lawn mowers, a fuel mixture is used in a ratio of 50: 1, where 50 is part of gasoline, 1 is part of oil. That is, 20 ml of oil should be added to 1 liter of gasoline. The table will help you choose the required ratio.

To correctly measure the proportions, use measuring containers with a milliliter scale. For THESE purposes, a special double-necked canister is perfect, it is designed for mixing and storing oil gasoline. For example, oil can be drawn with a medical syringe without a needle. Before mixing liquids Make sure that the ready-mix container contains water, dust and dirt particles.

It is unacceptable to dilute gasoline with lubricant directly in the fuel tank; moreover, the proportion of oil and gasoline must be strictly observed. If you ignore this rule, then the trimmer motor may be unstable, due to which it will quickly fail.

It is not recommended to use plastic bottles or canisters for this purpose. This is due to the fact that gasoline tends to dissolve plastic, which means that some of the plastic can get into the fuel tank, which can lead to carburetor breakdown. Although there are special plastic canisters with markings “flame”.

This will require:

  • Petrol;
  • Oil suitable for air-cooled two-stroke engines;
  • Canister, preferably metal;
  • Mixing vessel, also better metal;
  • Gloves;
  • Respirator.

In addition to protective equipment, do not forget about fire safety rules, because gasoline and engine oil are highly flammable:

  • It works better outdoors to avoid the accumulation of gasoline vapors indoors;
  • Do not smoke and create spark situations.

Make a mixture of gasoline and oil as follows:

  • Pour 1 liter of gasoline into a container, add half the required portion of oil. Mix thoroughly, do it with extreme caution away from sources of open fire.
  • Add the rest of the oil to the trimmer gasoline and mix thoroughly again. Fuel can now be poured into the trimmer fuel tank.

The mixture can be stored for no more than three months, so it is better to dilute gasoline in such an amount that it is enough for a few used.

Fuel mixture for two-stroke engines

Trimmers, which are equipped with a two-stroke engine, do not have a separate system designed to supply oil to lubricate the rubbing parts. For this reason, such devices should not be refueled with pure gasoline, but with a mixture of fuel and engine oil. The latter should be specially designed for two-stroke engines. Application of automotive engine fluid will result in premature engine failure.

Preparation of a fuel mixture for two-wheel engines

You need to refuel lawn mowers with a two-stroke engine with AI-92 gasoline. When using the AI-95, overheating of the engine and uneven operation of the unit may be observed. You need to mix gasoline with oil in a ratio of 50: 1, where 50 is fuel and 1 is oil. It turns out that 1 liter of fuel will require 20 ml of oil.

If the engine is worn out or the tool is operated with a high load, then the proportion is 25: 1. If there is little lubrication, then scuffs will appear on the walls of the cylinder and the surface of the piston. Then the piston ring will undergo destruction, causing the engine to jam. Excessive excess is NOT so critical, but it can lead to carbon deposits. At the same time, the piston ring will coke, which will reduce the power of the device.

The proportions of oil and gasoline for the fuel mixture

Standard proportions

First of all, it is necessary to take into account the information that the manufacturer recommends, since in the event of a failure of the lawn mowers, you can present your claims to him, and not to a third-party source. If there is no instruction in the passport, and even more so if there is no passport, we recommend that you look for another trimmer model in a more reliable seller.

For all other cases, when you have a lawn mower model in your hands and there is no way to find out its technical features, there are standard proportions of the Most probable fuel mixture components for a two-stroke engine. Basically, for THESE units, AI-92 gasoline and a special synthetic oil are used, which contains a solvent for better mixing with fuel. This oil evaporates slowly and has the ability to completely burn out in the cylinder, Do not leave carbon deposits.

The standard ratio of synthetic oil to gasoline is 1: 50. This means that 5 liters of gasoline need 100 ml of oil, and in accordance with this, oil consumption per 1 liter of gasoline is 20 ml. Knowing the amount of oil required to dilute 1 liter of fuel, you can easily calculate any rates when preparing fuel for the trimmer. When using mineral oils, a ratio of 1: 40 is most often the standard. Therefore, 1 liter of fuel will require 25 ml of such oil, and for a 5-liter canister. 125 ml.

When working with lawn mowers, a person with little experience in operating such equipment will not be difficult to determine and correct the actual amount of oil required for a particular model. You should only pay attention to Exhaust gases (their color, odor toxicity), cycle stability, engine heating and developed power. details about the consequences of incorrect mixing proportions of gasoline and oil can be expected in another section of the article. There are variants of lawn mowers running on AI-95 gasoline. This should also be considered.

If the manufacturer recommends fuel with such an octane number, then you need to follow the requirements so as not to reduce the operating resource of the equipment.

Which oil to choose

For effective trimmer operation, it is necessary to select oil for two-stroke engines. This is due to the lack of an oil sump in such a device. Depending on the chemical composition of the oil, the following classification is distinguished:

  • Mineral. based on petroleum distillate, suitable for low-power and air-cooled equipment, but requires frequent replacement and can only be used in good weather in the warm season;
  • Semi-synthetic. suitable for garden equipment with air and liquid cooling;
  • Synthetic. based on esters, and do not require frequent replacement and can be used at any time of the year.

Oil for 2-stroke engines is characterized by good solubility and complete combustion feature. It is recommended to use a lubricant for the trimmer that is suitable for air-cooled units. Most often, it is indicated on the packaging that the oil is intended for garden equipment and is marked I, TV or TC. over, the last of them is the most preferable.

If the consumption of engine oil during the summer season is planned to be large due to the presence of a chainsaw, brush cutter, lawn mower in the garden arsenal, then it is advisable to buy 5 liters of oil at a more favorable price. If it is needed only in order to mix with gasoline and fill the only tool, then 1 liter will be enough.

Lawn mowers often produce the right oil, so you can make your choice easier if you choose the right brand fluid.

Mixing rules

And now about how to mix the components correctly. However, it would be more logical to start with an analysis of common, but absolutely unacceptable mistakes, which many owners of this mowing unit “sin” with. The following actions are considered as mixing errors.

  • Adding oil to the fuel already in the mowers’ gas tank. Similarly, a homogeneous fuel mixture will NOT work. Perhaps it will work, if only then shake the trimmer for a long time. But it is unlikely that someone will do this by taking the weight of the unit.
  • First pour oil into a mixing container, and then add gasoline to it. Gasoline has a lower density than oil, so if it is poured into the oil, it will remain in the upper layer, that is, natural mixing will NOT occur. Of course, it will be possible to mix later, but much more energy will be required than if it were done the other way around. pour oil into the filled gasoline.
  • Ignoring accurate measuring instruments for taking the required quantities of ingredients used. In other words, diluting the amount of oil or gasoline “by eye” is a bad habit when operating motor vehicles.
  • Take empty drinking water bottles for preparation of the fuel mixture. Such a container is made of too thin polyethylene, which can be dissolved in gasoline.

Considering all of the above, we recommend using the following rules when mixing a fuel mixture for two-stroke trimmer engines.

  • Use only clean containers made of metal or special plastic for storage of gasoline, oil, ready-made fuel mixture and its preparation.
  • Use for filling gasoline into the LEIKOME dilution container in order to avoid spilling, and for adding oil. in a measuring container with volume risks or a medical syringe for 5 and 10 ml.
  • First, pour gasoline into the canister for preparing the fuel mixture, and then oil.
  • To dilute the mixture, first pour only half of the planned volume of gasoline into the container.
  • Next, add the entire amount of oil required to prepare the mixture to the gasoline.
  • Mix the contents of the dilution container thoroughly. It is best to stir by making circular movements with a tightly closed container. You should not stir the fuel inside the canister with any foreign object, since it is not known what material this object is made of, what reaction it can enter into with an ingredient in the mixture, how clean it is.
  • Add the rest of gasoline to the mixed mixture and mix thoroughly again.
  • You can refill the fuel tank of the lawn mowers.

It must be borne in mind that the ready-made fuel mixture does not have to be stored for more than 14 days, since it loses its properties, stratifies and evaporates, which leads to changes in proportions, and therefore, deterioration of trimmer performance.

Consequences of violation of the ratio

How to choose for lawn mowers?

For two-stroke engines, lawn mowers use AI-92 or AI-95 gasoline. Most often. the first of the named. There is always information about this in the technical data sheet of the product. If, for some reason, it is not known exactly on which gasoline the trimmer should work, you can choose it by testing both brands of gasoline in action. Global changes in the engine will not happen from this, and it is quite possible to determine what kind of gasoline and or another model of the unit “likes” more, according to some factors. This will be shown by the developed power, and throttle response, and engine heating, as well as its stable operation at all speeds.

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

For example, for Chinese low-power trimmers, two ratios are mainly used. 1: 25 or 1: 32. The first is for mineral oils, and the second is for synthetic oils. In the choice of standard proportions for lawn mowers of European and American manufacturers in connection with the type of oil, we have already told you earlier. According to the class of oils for household trimmers, you need to use TB oil according to the API classification. For more powerful. class TS.

For the ratio of gasoline to oil required for lawn mowers, see the following.
