What Oil Is Pouring Into A Petrol Trimmer

Choosing the wrong lubricating fluid for the motor is a trifle. Especially if you do not know how to distinguish compositions for different power plants. There was a time when KAMAZ lubricants were poured into the VAZ engines with the thought of what, in fact, the difference was. Then they were surprised at the suddenly lit up oiler due to a gelatinous precipitate and blocking the oil channels. What is the situation now – we will understand.

Expertise: is it possible to pour ordinary diesel oil into a gasoline engine – consequences

The fact that you can pour diesel oil into a gasoline engine, many say. But only a few emphasize the exclusivity of such a case. Why? Everything lies in the various processes of the motors.

Briefly about the differences between engines

So, diesel due to the high degree of compression is highly loaded in temperature terms. The duty cycle is organized in such a way that peak thrust is achieved at low speeds and there is no need to twist the unit. Due to the lack of a spark plug, it is difficult to ensure complete combustion of diesel fuel. An analysis of these factors shows that:

• Exhaust gases can erupt into the crankcase, causing oxidation of the lubricant located there.
• Sulfur oxides formed during the combustion of diesel fuel should not be exposed to rubbing surfaces. They must be bound with additives and excreted.
• The greater amount of air required for the diesel engine to function, provokes intense oxidation and carbon formation.
• Soot formed during incomplete combustion of fuel requires binding and elimination.

The operating conditions of the engine for light fuel are more favorable for the oily fluid. The compression ratio is lower, the temperature is lower. Gasoline burns out almost completely during a working cycle. There is only one negative point – optimal traction is achieved at relatively high speeds. And the engine spins much higher than diesel. But, this is if check nozzles , and clean the injector.

Oil differences

Looking at the motor processes, it is not difficult to conclude – the lubricant in the "diesel engine" works in much worse conditions. The high-octane emulsion here will fulfill its function at a decent level if:

1. The additive package to neutralize oxidation products will increase.
2. The alkaline number, which affects the level of opposition to the oxidation composition, will be increased.
3. The amount of ash additives will increase.

Often, diesel oil is poured into a gasoline engine to clean the insides due to the higher alkaline number. This is usually done before you clean the motor from soot by hand. We will talk about how effective this cleaning method is in a separate paragraph.

The reverse situation, when gasoline oil is refueled in a diesel engine, is unacceptable in principle. The process of carbonization and aging is intensifying. After all, additional funds to combat oxidation are not provided.

We recognize oils

For the right choice of lubricant, it is enough to pay attention to the classification. We won’t mention everything, we’ll only delve into a highly specialized group. It was created by the American Fuel Institute and is abbreviated as API.

The official link for the buyer’s information is the letters indicating the type of preferred motor:

• S – light fuel.
• C – diesel.

In an independent version, they are not used. They are additionally equipped with a symbol of the Latin alphabet (for example, SG). The farther it is from the beginning, the higher the quality of the product. Universal oils, found mainly in the synthetic class, are labeled with a “/”. For example: SG / CD.

Pour diesel oil into a gasoline injection engine for preliminary cleaning of the unit from the inside

An oil base, a large alkaline index and calcium additives – you can’t come up with a better composition for a preliminary engine wash. Why not for the main? Studies show that long-term operation on engine oil for diesel only contributes to the oxidation of deposits, but not decomposition and removal of them together with mining.

Many experts made sure that diesel oil can be poured into a gasoline engine for cleaning. In their opinion, the basis of the cleaning procedure is as follows:

• Change grease and filter.
• Drive 7-9 thousand km., Not exceeding 4,000 rpm.
• Drain mining.
• Clean the crankcase and the space under the valve cover.
• Collect and flush engine in a suitable way.

Using a diesel lubricant just for lubrication is not recommended. It contains additives that are not so effective when working at high speeds. Emergency refills during the service interval can be done only in extreme cases, when there is no suitable product at hand. This will obviously be a better solution than oil starvation.

Verdict

You can use lubricating oil for diesel in a gasoline engine only for flushing. The efficiency of this process is low – the sludge only softens. This method of cleaning can be considered as preliminary in advanced situations. It is usually followed by manual cleaning. Emergency mixing with gasoline grease is allowed.

Gas trimmers are some of the most popular grass mowing devices. They are easy to use, mobile, allow a person not to depend on the outlet and show excellent results in places of their use. But for the stable operation of the gas trimmer, quality supplies are needed. In particular, we are talking about gasoline and oil. It is about the last component that we will discuss in this article.

Appointment

Engine oil is a special mixture consisting of a solvent and additives that reduce friction. They form a certain viscosity and do not allow the composition to thicken when the temperature is lowered. Usually, oils are specially painted in various colors: green, red or blue. This allows them not to be confused.

Keep in mind that they may vary in composition, so oil for gas trimmers will be labeled “for gardening equipment”. In addition, it may still differ in labeling: “2T” or “4T”. The first is a two-stroke oil that is poured into the corresponding engine. And the second is intended for pouring into the crankcase.

Requirements

High-quality oil that can be poured into a gas trimmer must meet a number of requirements and standards to ensure reliable operation of the device and its performance. Oil should:

• To provide increased wear resistance for various elements (in particular, the gearbox is particularly susceptible to this);
• Ensure the lowest possible smoke and exhaust gases;
• Prevent premature ignition
• Mix well with gasoline when exposed to low temperatures;
• Have good viscosity and fluidity in various temperature ranges;
• Be as safe as possible in terms of environmental impact.

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

If mineral oils are used, mixing should occur 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 to 80. That is, a certain amount of oil dissolves in the volume of gasoline.

Varieties

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

• Mineral – this type is obtained during the processing of petroleum products;
• Synthetic – it is obtained during the processing or synthesis of gas;
• Semi-synthetic – this type has more advanced characteristics due to the introduction of synthetic-based components into it.

Lawn-mowing 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 analogues in additives, which give it certain additional characteristics. They are of the following types.

• Antiwear. The main objective of the oil will be to reduce the wear of parts during 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.
• Corrosion resistant. Their task is to prevent corrosion from forming on engine parts.
• Friction modifiers. These additives can significantly reduce the coefficient of friction.

Recently, when purchasing oil for dilution with gasoline, users very often encounter the fact that special letter abbreviations are applied to canisters. These designations are performed as part of the API classification. Consider what types of oils exist in accordance with it.

• TA applies to air-cooled lawn mowers, the engine capacity of which is not more than 50 cubic centimeters. It can be used not only for mowers, but also for mopeds, lawn mowers and other types of equipment. For a gas trimmer, this is the optimal solution.

• TB is used to refuel a chainsaw, scooter, moped or motorcycle, the engine capacity of which does not exceed 200 cubic centimeters. It can also be used for refueling gas trimmers.

• TC suitable for dilution with gasoline and pouring into a snowmobile, motorcycle and other types of equipment.

• TD is for refueling boats, yachts and hoverboards.

But in addition to this classification, other FA-FD type letters are often found. It should be said that the API is an American standard that is applied in Europe. But there is a mismatch between European smoke emission standards and American. For this reason, additional lettering should also be taken into account.

• FA can be used in countries where the law provides for minimal exhaust emissions. When using oil with this marking, faint smoke may be produced.
• FB – can be used in countries where smoke and gas restrictions are much stricter. In this case, smoke will hardly be emitted.
• FC – here appears smoke of a transparent color, which the human eye cannot notice.
• FD – a special category of oils for 2-stroke engines, they do not create smoke at all. They have enhanced chemical properties. Typically, this oil is used for mixing with gasoline and subsequent refueling of boats and yachts.

In addition, oils come in two more categories:

• Selfmix
• Premix

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

Selection tips

Now let’s try to understand how to choose high-quality oil for a trimmer that runs on gasoline. The main feature that you need to pay attention to is the alkaline number. This moment excludes the oxidation of parts in which friction is observed, and decelerates their deformation as much as possible. The more this compound is used, the faster it loses alkalinity and becomes more oxidized. The optimal indicator of acidity (PH) is a value of not less than 8-9 units.

The second important factor, which also has a major impact on the operation of the gas trimmer, is the viscosity of the oil. This characteristic determines the possibility of using the device at various temperatures. Summer brands of oils begin to thicken already with a minimum decrease in temperature.

The third point, the importance of which should not be minimized, 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. In addition, oil for a 4-stroke engine is not suitable for a 2-stroke. Namely, the latter type of motors is used in the vast majority of lawn mowers.

If we talk about manufacturers, then you can make a small rating, which will allow you to navigate in the compositions offered by various manufacturers. For instance, stihl company It offers high-quality synthetic and mineral oils that have already established themselves as an excellent solution at any time of the year.

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

How to use?

Information on the proportions of oil use was given above. We must say right away that you should not deviate from the indicated values ​​and dilute gasoline by eye. In the best case, you just need to change the oil, and in the worst you can’t avoid a motor breakdown.

It is important to be able to cook the mixture correctly. It is impossible to fill it in a gas tank. It is better to pour oil in a special container that already contains gasoline. A plastic mineral bottle 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, which will serve as a dosimeter. It is best to take a regular medical for 10 or more cubes.

Now step by step explain how to make good oil for a gas trimmer.

1. First you need to know exactly what type of oil is required for a particular model of the braid, and also find out the exact ratio of gasoline and oil to create a mixture.
2. Then you need to fill the container. The tank should not be filled with gasoline to the end, because the oil should also fit there;
3. Now we collect the necessary amount of 2-stroke oil into the syringe and pour it into a bottle with gasoline. You can’t do the opposite, otherwise you will need to replace all the ingredients, and the mixture will need to be done again.
4. Close the bottle with a lid and stir. It is important not to forget that stirring the mixture is necessary if there are Premix words on the oil bottle. If Selfmix is ​​written there, then after mixing the substances everything is poured into the tank.

Now it remains only to refuel the gas trimmer, and you can carry out the necessary work.
