How much oil to add to the grass trimmer

Requirements

A quality oil that can be poured into a gasoline grass trimmer must meet a number of requirements and regulations to ensure reliable operation and performance. The oil should:

  • provide an increase in wear resistance for various elements (in particular, the gearbox is especially susceptible to this);
  • to ensure the formation of smoke and exhaust gases is as low as possible;
  • do not allow premature ignition;
  • mix well with gasoline when exposed to low temperatures;
  • have good viscosity and flow characteristics in various temperature ranges;
  • be as safe as possible in terms of environmental impact.

As mentioned, two-stroke engine oil will differ from four-stroke engine oil. It has higher power, which is why fuel for it is obtained by mixing a certain amount of gasoline and oil. For each brushcutter, the ratio will be different. You can find out its meaning in the instructions for the device. These proportions must be observed with maximum accuracy. When adding additives, take into account the type of motor.

If mineral oils are used, mixing should be somewhere in the ratio of 1: 25, 30 or 35, depending on the type. If we are talking about a synthetic analogue, then the proportion will be 1: 50 or 80. That is, a certain amount of oil dissolves in the volume of gasoline.

Petrol trimmer oil: types and recommendations for use

Gasoline grass trimmers are some of the more popular lawn mowing attachments. They are easy to use, mobile, allow a person not to depend on an outlet and show excellent results in the places where they are used. But for the stable operation of the gasoline grass trimmer, quality consumables are needed. In particular, we are talking about gasoline and oil. It is about the last component that we will talk about in this article.

Varieties

The oil that is poured into the motor may differ in the production method. According to this criterion, it happens:

  • mineral. this type is obtained during the processing of petroleum products;
  • synthetic. it is obtained by processing or synthesizing gas;
  • semi-synthetic. this type has better characteristics due to the introduction of synthetic-based components into it.

Lawn mower oil refers to formulations intended for use in air-cooled engines that have a combustion chamber volume of 50-200 cubic centimeters. In addition, any two-stroke oil can differ from analogs in additives that give it certain additional characteristics. They are of the following types.

  • Antiwear. The main task of the oil will be to reduce wear of parts during the operation of the device.
  • Antioxidant. They do not allow oxidation to occur and make it possible to maintain the performance of the oil for a long time.
  • Anti-corrosion. Their task is to prevent corrosion from forming on the engine parts.
  • Friction modifiers. These additives can significantly reduce the coefficient of friction.

Two-stroke oil from different manufacturers may differ in the combination of additives used, which means that their properties will differ.

Recently, when purchasing oil for dilution with gasoline, users very often come across the fact that special letter abbreviations are applied to the cans. These designations are made within the framework of the API classification. Consider what types of oils exist in accordance with it.

  • TA is used for air-cooled brushcutters with an engine displacement of no more than 50 cubic centimeters. It can be used not only for mowers, but also for mopeds, lawn mowers and other types of machinery. For the petrol grass trimmer, this is the optimal solution.
  • TB is used to refuel a chainsaw, scooter, moped or motorcycle with an engine capacity of less than 200 cubic centimeters. Can also be used for refueling petrol trimmers.

But in addition to this classification, other letter designations of the FA-FD type are often found. It should be said that the API is an American standard that is used in Europe. But there is a discrepancy between European and American smoke emission regulations. For this reason, additional letter designations should also be taken into account.

  • FA can be used in countries where minimum exhaust gas emissions are required by law. Barely noticeable smoke may be emitted when using oils with such markings.
  • FB. can be used in countries where the restrictions on the emission of smoke and gases are much stricter. In this case, the smoke will practically not be emitted.
  • FC. a transparent smoke appears here, which the human eye cannot notice.
  • FD is a special category of oils for 2-stroke engines, they do not create smoke at all. They have increased chemical properties. Usually this oil is used for mixing with gasoline and subsequent refueling of boats and yachts.

In addition, oils come in two more categories:

In the first case, this will mean that it is necessary to carry out self-mixing, which does not require shaking, and in the second case, you will need to do it too.

Selection Tips

Now let’s try to figure out how to choose a quality gasoline grass trimmer oil. The main feature to look out for is the base number. This moment excludes the oxidation of the parts that have friction and slows down their deformation as much as possible. The more this compound is used, the faster it loses its alkalinity and becomes more oxidized. The optimal indicator of acidity (PH) is a value of at least 8-9 units.

The second important factor that also has a major impact on the performance of a gasoline grass trimmer is the viscosity of the oil. This characteristic determines the ability to use the device at different temperatures. Summer brands of oils begin to thicken already with a minimal decrease in temperature.

But given that these grass trimmers are usually used in the fall and spring, it is best to use just the oil with summer markings.

The third point, the importance of which should not be underestimated, is the flash point. This indicator should not be less than 225 degrees. Otherwise, the composition will burn out very quickly and the load on the piston group will begin to increase, which will cause its accelerated wear. Also, 4-stroke oil is not suitable for 2-stroke. Namely, the latter type of motors is used in the vast majority of gas mowers.

If we talk about manufacturers, then you can make a small rating that will allow you to navigate the formulations offered by various manufacturers. For example, STIHL offers high-quality synthetic and mineral oils that have already proven themselves as an excellent solution at any time of the year.

Shell Helix Ultra oil is considered very good. Experts note its high characteristics and excellent indicators of alkalinity and viscosity. In addition, the products of such brands as Oleo-Mac, Motul, Hammerflex, Echo are considered worthy. If we talk about the products of domestic brands, then you should pay attention to Lukoil oil. Its price is several times lower than foreign counterparts, but at the same time it has high quality and good technical characteristics.

In general, the ideal solution would be a synthetic or semi-synthetic oil labeled TV or TA.

Appointment

Engine oil is a special blend of solvent and friction-reducing additives. They form a certain viscosity and do not allow the composition to thicken when the temperature is lowered. Usually oils are specially colored in different colors: green, red or blue. This allows them not to be confused.

Please note that they may vary in composition, so petrol trimmer oil will be labeled “for gardening”. In addition, it may still differ in marking: “2T” or “4T”. The first is two-stroke oil, which is poured into the corresponding engine. And the second is intended for pouring into the crankcase.

In addition, you should be aware that under no circumstances should mineral and synthetic oils be mixed due to the fact that they have a different base.

How to use?

For the proportions of oil used, see above. We must say right away that you should not deviate from the indicated values ​​and dilute gasoline by eye. At best, you just need to change the oil, and at worst, engine damage cannot be avoided.

It is also important to be able to prepare the mixture correctly. It cannot be poured into the gas tank. It is better to pour the oil into a special container that already contains gasoline. A plastic bottle of mineral water is perfect for this. It is very important that it is clean, which is why beer or milk bottles will not work. And it is better that it be a liter or two-liter, since it will be difficult for many to calculate how much oil to fill in a 1.5-liter or 1.25-liter bottle. You will also need to have a syringe on hand that will function as a dosimeter. It is best to take a regular medical one for 10 or more cubes.

Now we will explain step by step how to make a good gasoline grass trimmer oil.

  • First, you need to know exactly what type of oil is required for a particular model of grass scythe, as well as find out the exact ratio of gasoline to oil to create a mixture.
  • Then you need to fill the container. The container should not be filled with gasoline to the end, because the oil must still fit there;
  • Now we draw the required amount of 2-stroke oil into the syringe and pour it into a bottle of gasoline. You cannot do the opposite, otherwise all the ingredients will need to be replaced, and the mixture will need to be done again.
  • Close the bottle with a lid and stir. It is important not to forget that you need to stir the mixture if there are the words Premix on the bottle of oil. If it says Selfmix, then after mixing the substances, everything is poured into the tank.

Now all that remains is to refuel the petrol grass trimmer, and you can carry out the necessary work.

For information on how to choose oil for gasoline trimmers, see the next video.

Ratio of gasoline and grass trimmer oil

Gasoline mowers are quite common tools used by owners of garden and backyard farms for mowing grass and making hay. The more common names for tools are grass trimmer and lawn mower. The main difference lies in the design of the motor. the expensive segment of devices is equipped with four-stroke models, and the cheap ones are equipped with two-stroke ones. The latter option has advantages, including low weight, ease of use, and 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 reduction in the resource of the tool and even to its breakdown. Let’s figure out what composition is required for gasoline trimmers, how to properly prepare the mixture and what it can affect.

How Much Oil to Dilute Per Liter of Gasoline Grass Trimmer

How to dilute gasoline with grass trimmer oil?

The grass trimmer specification contains links to recommended fuels and lubricants. In this case, the octane number of the brand of gasoline is indicated specific, but in the part of oils there is an extensive explanation about the need to use a product of a certain manufacturer. How much grease is required to dilute by 1 liter per grass trimmer oil and gasoline. For assurance, it is indicated that only when these tips are followed, the company extends the warranty. What is it: a publicity stunt or oils from other manufacturers do not meet the requirements? The answer is in the true article.

Standard proportions

First of all, it is necessary to take into account the information that the manufacturer recommends, since in case of failure of the brushcutter, 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, then we recommend that you look for another model of grass trimmer from 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 likely fuel mixture components for a two-stroke engine. Basically, these units use AI-92 gasoline and a special synthetic oil, which contains a solvent for better mixing with fuel. Such oil evaporates slowly and has the ability to completely burn out in the cylinder, leaving no carbon deposits.

The standard ratio of synthetic oil to gasoline is 1: 50. This means that 5 liters of gasoline requires 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 rate when preparing fuel for your grass trimmer. When using mineral oils, the 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 operating a lawn mower, 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 the 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 options for brushcutters running on AI-95 gasoline. This should also be considered.

If the manufacturer recommends fuel with such an octane number, then the requirements must be followed so as not to reduce the operating resource of the equipment thereby.

What gasoline to fill

Gasoline for the grass 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 lawnmower lubricant and diluting it in a separate container. It is also recommended to use special canisters designed for storing gasoline.

Why Mix Grass Trimmer Oil with Gasoline

The two-stroke engine has an ordinary and, at the same time, very efficient design:

All this determined the creation of a family of small engines that were successfully adapted in household and professional equipment:

  • grass trimmers;
  • chainsaws;
  • bikes;
  • different motoblocks.

Due to the design features, it was possible to achieve the desired fuel consumption only on small engines with a power in the range of 15. 20 hp. This indicator looks especially great in the range of 1. 5 hp. Here, the completely low weight and dimensions of the motor correspond to the consumption of gasoline.

As the size increases, the area of ​​the inlet and outlet channels increases. Like “how much oil to pour on 1.2.5 should be 50 ml. Oil (1 liter of gasoline is needed. The process of gas removal and fuel supply deteriorates sharply. In this regard, it was necessary to switch to a more efficient gasoline mixture combustion system, which would provide for the presence of forced engine maintenance systems. Combining them into multi-cylinder designs allowed the creation of special systems associated with the formation of the composition of the fuel mixture, lubrication and other things, which favorably affected the consumption of gasoline.

The rubbing elements of the piston and cylinder of a two-stroke engine are lubricated with oil, which is in a certain proportion in the fuel composition. How much oil 25 ml of oil per liter of gasoline. If you do not add oil to the fuel, how much oil is there per 1 liter of gasoline in the chainsaw. Dilute gasoline for. Gasoline burns out, and oil settles on the surface of the cylinder, reducing the friction of the rubbing parts. Lack of lubrication leads to cylinder damage, up to and including seizure. In case of excess, under the influence of high temperatures, the thermally modified product is deposited in the annular grooves. Compression drops, and with it power.

We deal with the choice of gasoline for a lawn mower AI-92 or AI-95

How many people, so many opinions, which applies not only to the choice of oil for the grass trimmer, but also gasoline. Similarly, in order not to make a mistake with the choice, it is recommended to use gasoline of the brand recommended by the manufacturer (indicated in the manual for the tool). However, everything is not so simple here, since at each gas station, the brands of gasoline are only called the same, but they have a completely different composition. You need to figure it out and come to a common conclusion about which brand is better to pour gasoline into a two-stroke engine for your grass trimmer.

Manufacturers recommend using A-92 gasoline for their equipment, and some models require the use of A-95 grades, which do not contain ethyl alcohol. It is not recommended to use AI-90 and lower gasoline, as they will cause rapid wear of engine parts. When buying gasoline of one brand, you cannot be 100% sure that it corresponds to reality. The result is the following picture:

  • The manufacturer recommends adding fuel to the AI-92 grass trimmer
  • The summer resident uses only gasoline of this brand, but buys it at gas stations, where the price is lower or where necessary
  • This negatively affects the internal details of the engine, since at one gas station it is really high-quality AI-92 gasoline, and at the second. at best, if it is AI-80, not AI-76

As a result, the motor suffers, and after a couple of years of operation of the new grass trimmer, it becomes necessary to overhaul it. In order not to have to analyze the quality of fuel or buy only expensive gasoline, it is recommended to refuel at only one filling station. At filling stations, gasoline is poured only into metal cans, not plastic.

There are manufacturers producing special purified fuel for two-stroke engines. If this option is chosen, then you do not need to choose the best gas station, the brand of gasoline and control its shelf life.

Conclusion on choosing gasoline for your grass trimmer! The grass trimmer must be filled with gasoline of the brand recommended by the manufacturer. If you pour A-95 gasoline into the grass trimmer tank, instead of A-92 (which is recommended by the manufacturer), the engine will warm up faster and work unstable. It is also better to choose gasoline A-92 Ecto, which has improved characteristics in terms of environmental friendliness.

How to Choose Grass Trimmer Oil or Lubricants

grass trimmers and lawn mowers are powered by two-stroke engines, which are simplified in design. Rarely, there are trimmer models with 4-stroke engines that run on pure gasoline. Two-stroke power units do not have a compartment for filling engine oil (oil sump), thereby reducing the weight of the tool and reducing their cost. If the rotating parts of the motor are not lubricated, they will eventually fail quickly. To prevent this, the grass trimmer is not filled with pure gasoline, but with a mixture of oil. What oil to dilute with gasoline for a grass trimmer?

To begin with, let’s remember or find out what types of oils are produced in terms of chemical composition:

  • Mineral liquids. designed for low power equipment with air cooling. It is the cheapest type of engine lubricant.
  • Semi-synthetic substances. they are used for equipment that has air and water cooling
  • Synthetic. suitable for all types of motors with different types of cooling. They do not require frequent replacement, and this type of lubricant is several times more expensive than mineral and semi-synthetic

From the above, it follows that oil with any composition is suitable for a grass trimmer. mineral water, synthetics and semi-synthetics. Oils with different chemical composition differ in price, therefore, when buying, it is necessary to rely on the recommendations of the tool manufacturer. The instructions indicate advisory information on which types of oils are best to use. If this is the TC-W3 standard, then it is not so important what composition the substance should have. In this case, mineral water, semi-synthetics and synthetics can be diluted with gasoline.

It is interesting! The main thing when choosing an oil is not to fall for a fake, since today you can very often find different types of lubricants for two-stroke engines, which consist mainly of low-quality oil products.

A properly prepared fuel mixture is the key to efficient operation and long engine life. The composition burns out completely, does not leave carbon deposits and does not harm the working components. Our short instruction will help you understand the intricacies of the process of mixing oil with gasoline.

Consequences of violation of the ratio

The service life of the motor scooter engine depends on how accurately you follow the manufacturer’s recommended oil-gasoline ratio. 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, and somewhere it will not be enough at all, the parts that touch 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 in the direction of a lack of oil. It is better to pour a little oil 10 times than not to add just 1 time. It often happens that this time is quite enough to break the engine.

Rules for pouring the mixture into different engines

The basic rule is to strictly observe the mixing ratio for two-stroke engines and not use such formulations for four-stroke engines. In addition, observe the principle of “seasonality”. after a long stay of fuel in the gas tank, drain it and replace it with fresh.

Why Mix Grass Trimmer Oil with Gasoline

The two-stroke engine has a simple yet extremely efficient design:

  • the piston makes a working stroke every second stroke;
  • the cylinder is lubricated with oil dissolved in gasoline;
  • removal of combustion products occurs due to compression, without a special mechanism.

All this led to the creation of a family of small engines that have been successfully adapted in household and professional equipment:

  • grass trimmers;
  • chainsaws;
  • motorcycles;
  • various motoblocks.

Due to the design features, it was possible to achieve the desired fuel consumption only on small engines with a power in the range of 15. 20 hp. This figure looks especially good in the range of 1. 5 hp. Here, in full measure, the low weight and dimensions of the engine correspond to the consumption of gasoline.

As the size increases, the area of ​​the inlet and outlet channels increases. The process of gas removal and fuel supply deteriorates sharply. In this regard, a transition to a more efficient gasoline mixture combustion system was required, which would provide for the presence of forced engine maintenance systems. Four-stroke models have thus intercepted the palm among high-power powertrains. Combining them into multi-cylinder designs allowed the creation of special systems associated with the formation of the composition of the fuel mixture, lubrication and other things, which had a beneficial effect on gasoline consumption.

The rubbing elements of the piston and cylinder of a two-stroke engine are lubricated with oil, which is in a certain proportion in the fuel composition.

Algorithm of actions

Fuel quality increases with proper mixing of the mixture components. The question arises before the mower, how to breed, in what sequence. When mixing the components, pay attention to whether the containers are cleanly washed. A tiny slurry can stall the fuel supply to the carburetor. The fuel tank should be filled from a special container with a filter device.

The procedure is as follows. Half of the available gasoline is mixed with the volume of the specified amount of lubricant. This is followed by the mixing process.

When the components acquire a homogeneous consistency, 50% of the remaining fuel is poured into the partially diluted gasoline. This is how it is recommended to dilute the grass trimmer fuel.

How and how much to refuel

Refilling the grass trimmer’s fuel tank is easy. To do this, place the tank so that the lid is on top. The amount of fuel depends on the grass trimmer model. This information is indicated in the instructions, there is also a mark directly on the tank.

It is strictly forbidden to overfill the tank.

Doing so can cause fuel to spill into the intake manifold and fuel filter, which could cause engine damage or fuel ignition.

When refueling the grass trimmer, the following safety precautions must be followed:

  • try to fill in the liquid so that it does not spill, you can use a watering can for this;
  • if gasoline still spills, then it must be wiped up immediately;
  • the start of the grass trimmer must be started after the container with fuel is removed to a safe and secure place, preferably at a distance of more than 10 meters;
  • during a long break between operations, drain the remaining fuel.

Correct proportion and adherence to mixing and filling techniques will help extend the life of your grass trimmer. At the same time, it is recommended to choose only a high-quality product of the corresponding brand.

Problems with equalizing pressure in the gas tank

This malfunction is associated with a dirty breather. When this part is clogged, a vacuum forms in the gas tank, which prevents the supply of fuel. You can clean the breather using a regular needle.

If, after checking these grass trimmer systems, it does not start, most likely the reason is a problem with the carburetor (clogged jets, broken tightness) or the engine (worn piston rings, chips on the cylinder). Repair of this type can also be done independently, but it is better to trust the specialists of the service center.

What two-stroke engines dislike?

When preparing the working mixture manually, it should be remembered that two-stroke engines do not reach their 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 brushcutters with an underfilled lubricant product. there is an oil starvation of the engine, which does not allow the unit to be brought to the rated power.

Excess lubricant prevents the engine from developing the required power. When preparing the working mixture, a reasonable question arises, how much oil needs to be mixed in gasoline. Helps to define the exact standard. It is recommended that gasoline is poured into the grass trimmer 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 grass trimmer mower per 5 liters. The owner of the brushcutter gets the ideal fuel in terms of structural composition.
