How to dilute gasoline for a lawn mower

How to correctly dilute gasoline for a grass trimmer

Depending on the type of trimmers, they can be filled with a fuel mixture or separately with gasoline and oil. Now there is a huge variety of types of engine oils, which are suitable for different equipment, including garden. In order to choose the right fuel for your particular brushcutter model, you need to know its technical features and be familiar with gasoline brands and liquid lubricants. on how to mix petrol and oil for trimmers, read.

Depending on the engine device, brushcutters are divided into two-stroke and four-stroke. The first cycle of the combustion engine uses two strokes for the first cycle, and the second cycle uses four strokes. Differences in the working principle of the engine and cause different approaches to refueling trimmer for grass.

Fueling a brushcutter with a two-stroke engine

The common household brushcutter models usually use a two-stroke engine. Lawn trimmers do not need very high power and sharpness, so it is quite suitable for the task at hand. This engine is also much cheaper and simpler, but it is filled with a fuel mix of oil and gasoline. This fuel is filled into the carburetor and fed to the cylinder in the form of an oil and gasoline mist. In this way oil provides lubrication of all necessary parts, and in the process of engine operation it is burned together with petrol. But this mixture burns, producing a pungent smell and smoke, which increases the toxicity of the exhaust fumes.

Important! You need to use special oil for two-stroke engines for these brushcutters. This oil burns completely without leaving any carbon buildup and has low volatility. And to mix it well with petrol, it contains 20% of solvent.

Fueling brushcutters with four-stroke engines

The four-stroke engines are used in professional brushcutter models. They have high power and can run for a long time without interruption or refuelling. They also use gasoline and oil as fuels, but are fed into different tanks. Which means that oil is not involved in the combustion process, so the exhaust gases are not as toxic.

For your information! In addition to better environmental performance and less heat, four-stroke brushcutter engines are also more economical. They consume much less fuel. savings up to 50% for gasoline and up to 80% for oil.

Oil requirements

The mix of petrol and oil you choose for your brushcutter must comply with the prescribed specifications. It’s important to note that Russian producers often label their products differently from the American or Japanese classification. Russian producers of lubricants, as a rule, put a 2T marking on all oils intended for two-stroke engines. It is not uncommon to find oil cans marked “self-mix” or “pre-mix” on store shelves. In the first case it means that the oil does not require any additional manipulations, just pour petrol and oil into one container, and mixing will take place without human intervention. In the second case, respectively, you will have to shake or shake the mixture to bring it to the right consistency.

As you can see, the existence of different classifications of lubricants suggests that the use of oils in two-stroke engines is necessary. This is due to the fact that the fuel mixture without lubricant fairly quickly disable the ICE, which will not be lubricated properly. Gasoline and oil form the necessary environment that reduces detonation, removes excess debris (waste produced by the combustion of gasoline products), and protects the engine interior from wear.

It is important to remember that using the wrong oil classification can cause engine damage or blockage. It will of course be repairable, but to prevent and minimize the risk of malfunctions, it would be better to study the instruction manual, find out the engine capacity of the two-stroke engine installed on the brushcutter and use only petrol and oil that are compatible with this model by all parameters.

Quite often, in the recommendations section (and sometimes on the label as well), a manufacturer indicates the partner companies, which gasoline and oil it recommends to fill up their models. often than not, the fuel and lubricant recommended by the manufacturer will suit the grass trimmer best.

First of all, it is necessary to immediately exclude from the list of actively used lubricants all oils of unknown (garage, basement) origin. Usually it is not easy to dilute such oils because of the unclear basis, composition. As a rule, labels of non-branded producers do not contain a lot of information, covering only general information, without specifying. It is highly discouraged to dilute and dilute oils such as AC-10 and ACZp-10. The origin of these lubricants is usually quite vague, it is better to give preference to the proven brands that thousands of people use every day all over the country.

A distinctive feature of all oils for two-stroke engines is the fact that manufacturers paint them in a color that contrasts with gasoline. The fluid is semi-transparent, viscous in consistency, slightly yellowish, but not thick. There are usually three colors involved. red, green and blue.

Do not forget that the color scheme has no effect on the classification (as is often the case with antifreeze).

Under no circumstances should you use oils from a line not designed for the grass trimmer. It can extremely negatively affect the operation of the power unit, lead to increased fuel consumption, soot on the plugs and a variety of other problems that will have to be identified and eliminated. It should be noted that if the fact of using oil that is not in the tolerance is established, the seller has the full right to withdraw the machine from warranty. This means that the replacement of defective parts have to be at their own expense, and no exceptions do not help here.

If the fluid you have purchased is not of the quality you claim (for example, too thin), you should never mix it with gasoline. It will be best to return such oil back to the store, explaining to the seller the reason for return.

What are the chainsaw’s characteristics??

If you have a cottage or house in the countryside, you need a chainsaw. An ordinary chainsaw is quite enough for gardening. It is not powerful, but it is enough to remove old tree branches, cut firewood and boards. This saw does not have much weight or size. If you need to cut down trees in your yard or are planning construction work, a semi-professional chainsaw is the better choice. It should not work for more than 8 hours a day. A professional chainsaw has high power and can run for up to 16 hours in a row. High-strength materials are used to make these saws, and use requires some skill. Professional chainsaws are used for felling wood on an industrial scale and for other similar jobs.

All of these types of saws vary in both power and weight. If you’re not planning on doing big, permanent jobs, it’s better to stick with the cordless chainsaw, which weighs much less and is therefore easier to handle. Professional saws, on the other hand, have a power up to 6 kW and, accordingly, more weight. The choice of such a saw depends on the thickness and strength of the material to be sawed.

Mixing Rules

To prepare the fuel mixture, you must use a clean and dry container that is free of foreign matter or contaminants. Do not use plastic containers. After adding the correct proportions of liquids, stir the mixture thoroughly for 2 to 3 minutes. You can’t do the following:

  • Adding oil directly to the brushcutter fuel tank, as it will not form a homogeneous fuel mix;
  • Pour the oil first, and then the gasoline. Because of the difference in density, this order of adding components also makes the mixture not homogeneous4
  • Metering by eye. With this approach to achieve the exact proportion of gasoline and oil for grass trimmer 1/50 or 1/40 is not possible;
  • Use polyethylene bottles, as the latter are dissolved by gasoline.

The gasoline-oil ratio is different than recommended.

How much oil per liter of gasoline is needed for a lawnmower or chainsaw

All 2-stroke engines run on a mixture of gasoline and oil. Fuel enters the cylinder, burns there, creating a working force on the piston, and the part of the mixture that has not had time to ignite, lubricates the moving parts of the piston group.

When putting together a fuel mix for your lawnmower or chainsaw, calculate how much oil you need per liter of gasoline based not only on the standard ratio, but also on what brand of gasoline and oil is used. In the case of two-stroke motors, this is very important.

For trimmers, a special two-stroke oil is produced, which should be marked “2T” on the package. It is strictly forbidden to use automobile, and even more so, transmission oil. Two-stroke oil comes in three types:

It all depends on the ingredients in the oil base. Mineral oil is the cheapest and unreliable. Its use is justified only in household trimmers that operate for 30 to 60 minutes a day with long pauses. Most brushcutter manufacturers at this level indicate that TC-W3 grade oil is suitable for the engine. This means that you can use mineral, synthetic and semi-synthetic 2T oil.

For professional-grade brushcutters, it is advisable to buy only the oil brands recommended by the manufacturer. Usually semi-synthetics and synthetics with special additives.

Manufacturers label the oil with letters:

  • ? TA. for two-stroke motors up to 50 cc;
  • ? TV. for engines of 50 to 200 cc;
  • ? 2T is for motorcycle engines, snowmobile engines, etc.д.

In brushcutters, if the type of oil is not specified in the instructions, you can pour all three modifications. How much oil to add to your grass trimmer fuel depends on the brand of the tool and the quality of the gasoline. Also on the oil package there may be letters FA, FB, FC, etc.д. They show the level of smokiness. The closer the second letter is to the beginning of the alphabet, the more smoke is emitted. As a rule, quality oil has very little. The choice of oil is not affected by this indicator.

important than the labels “self mix” and “pre mix”. The first word means that the oil dissolves itself, and the container with the second mixture must be shaken several times.

If the manufacturer’s instructions do not specify what kind of gasoline to use, it is necessary to stop at AI-92. If recommended is AI-95, do not use other brands of gasoline.

Some users believe that if you add more oil to the gasoline for the fuel mixture than necessary, it will benefit. It’s not. The unburned oil is not carried away by the exhaust gases but is deposited inside the engine as sludge. This buildup threatens the integrity of the piston. If you use a mixture with too much oil regularly, the grass trimmer will smoke a lot, and a drop in power is inevitable.

If there is not enough oil, the weed trimmer will overheat, the piston rings will collapse and the piston will jam. If the oil deficiency is insignificant, the grass trimmer will work for 30. 40% less resource. If you lack more than 20% lubricant, the engine will jam after 20 to 30 minutes of intensive work. Each trimmer manual gives proportions on how to dilute the fuel mixture. It’s usually 1:25. 1:40 or 1:50.

Mixture requirements for a two-stroke engine

The difference of a two-stroke engine is its higher power as compared to a four-stroke engine. The fuel mixture for it is prepared in a certain ratio of petrol and special oil. You can find the optimum ratio of oil to petrol for your lawnmower in the owner’s manual. The recommended proportions have to be followed precisely. When adding additives the manufacturer has considered the type of engine. Do not mix different oils.

When using mineral oils, mixing is done in proportions of 1:25, 1:30, 1:35. For synthetic oils use a ratio of 1:50 or 1:80. This means that in each of the suggested mixtures, the right amount of oil is dissolved in the volume of gasoline. Mixing gasoline with lawnmower oil is like mixing water with syrup. It is necessary to pour petrol, add the exact amount of oil and shake the mixture. For work it is desirable to use a fresh solution. If stored for more than 2 weeks, the composition will change and the oil film will cause the carburettor to malfunction.

Do not use PET bottles for diluting and storing the mixture. Petrol destroys plastic, the polymer dissolves in the combustible mixture and further deteriorates the quality of the fuel, there is a risk of stray currents.

Choosing the right oil for your chain saw

Two-stroke engines are filled with a mix of unleaded petrol and 2T oil. Use recommended AI-92 gasoline. If a higher octane rating is used, the flash and combustion temperature will be higher, and the valves will burn out prematurely. The same applies to oil. Recommended compound is not the most expensive. But you can’t use another brand. Viscosity will change, it will lead to insufficient lubrication of conventional products made without high-precision lapping.

If you add too much oil, incomplete combustion will lead to carbon deposits and excessive exhaust emissions. A rich mixture is bad for the engine. For four-stroke engines, oil is filled separately from gasoline. It washes components, cools, reduces friction. The oil gets contaminated during operation and must be changed after 50 operating hours. What oil to use in the lawnmower is listed in the owner’s manual. The composition should be marked as 4T with a viscosity grade of 10W40.

The best oil for any engine is considered to be the recommended. But the world famous oil is Shel Helix Ultra. The company has been developing a new technology of synthetic oil from natural gas for 40 years. Pureplus technology has optimized the composition of the base oil. It is the basis for the recommended oils for their equipment by the leading manufacturers, with the necessary additives.

Choice of oil depends primarily on the manufacturer’s recommendation. For example, STIHL lawnmower oil is only used by brand-name STIHL lawnmowers. The same oil is suitable for the brand Vityaz, since the engines of the brands. According to experts, any manufacturer’s oil intended for one type of machinery is suitable for use in all brands. But if you can, it is better to use the recommended oil.

You need to have a supply of oil for one season. Product that has been sitting for a long time loses its properties. Available in packages of 0.1 to 5 liters.

Investigated the path of oil recommended for Husqvarna lawnmowers. The company does not have its own production, only a bottling plant. The product, which has been purchased in bulk, is then filled into small containers, labelled and delivered to the stores. Possibly exclusive Husqvarna additives were added to the oil at the manufacturing stage.

Use of oil according to the instruction manual for the brushcutter is obligatory. The machine cannot be operated on pure gasoline.
