How to Properly Dilute Gasoline For a Trimmer

Depending on the variety 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 motor oils that are suitable for various equipment, including garden. In order to choose the right fuel for a particular model of Lawn Mower, you need to know its technical features and understand the brands of gasoline, as well as liquid lubricants. All details on how to dilute gasoline with trimmer oil are in the material below.

Features of refueling motokos

Depending on the engine design, the scythes are divided into two-stroke and four-stroke. In the first case, the piston in the internal combustion engine makes 2 strokes in one working cycle, and in the second case. 4 strokes. Differences in the operating principle of the engine determine the different approaches to refueling the trimmer.

Refueling with two-stroke engine

In ordinary household models, a motokos uses, as a rule, a two-stroke engine. For the brushcutter does not need a very large power and agility, so it is quite suitable for the fulfillment of tasks. In addition, this engine is much cheaper and simpler, but it is fueled with a fuel mixture that consists of oil and gasoline. Such fuel is poured into the carburetor and fed into the cylinder in the form of oil-gasoline fog. Thus, the oil provides lubrication of all necessary parts, and during the operation of the engine burns out along with gasoline. However, the combustion of this mixture is accompanied by the release of a pungent odor and smoke, which increases the toxicity of exhaust gases.

How to Properly Dilute Gasoline For a Trimmer

Important! For such motokos it is necessary to use a special oil for two-stroke engines, which completely burns out without leaving a burn, and has low volatility. And so that it mixes well with gasoline, it contains 20% of the solvent.

Four-stroke engine refueling

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

On a note! Along with the best environmental performance and the ability to heat less, four-stroke engines of motokos are also more economical. They consume much less fuel. savings reach up to 50% in gasoline and up to 80% in oil.

Rules for choosing gasoline

Before buying fuel for your Lawn Mower, you need to read the manufacturer’s instructions. It indicates the grades and brands of fuel that can be used for a specific trimmer model. In general, when choosing gasoline, you need to focus on the A-92 brand. A-95 is also suitable for refueling Lawn Mower, although some experts do not recommend taking fuel with such an octane rating. This is due to the fact that at many gas stations, the composition of such gasoline includes various additives and solvents (for example, alcohol). It should be borne in mind that you can’t save money in this matter. in order to extend the life of the brushcutter, you should choose only high-quality fuel from trusted suppliers.

Oil Selection Rules

Motor oil, depending on the chemical composition, can be:

  • mineral. is made from petroleum distillates and is intended for low-power equipment with air cooling;
  • semi-synthetic. is a mixture of mineral and synthetic oils and is suitable for 2T and 4T, as well as for air and liquid cooling;
  • synthetic. made on the basis of esters and can be used in powerful technology, as well as for working in difficult climatic conditions.

Important! Oils for two-stroke and four-stroke engines differ in their ability to dissolve, burn and evaporate. At the same time, so that the liquid lubricant differs from gasoline, it is painted in different colors: blue, green, red.

Depending on the API classification, the following groups of oils for trim motors can be distinguished:

  • TA. for low-power equipment with an engine capacity of up to 50 cm³ and air cooling;
  • TV. for powerful equipment with an engine capacity of 50-200 cm³ and an air cooling system;
  • TS. for powerful two-stroke equipment (motor-scythes, chainsaws, lawn mowers, etc.) with an engine volume of 50-200 cm³;
  • TD. for boat engines with liquid cooling.

To choose the optimal oil for a particular trimmer model, it is better to take into account the recommendations indicated in the instructions. For motokos 2T API-TV and API-TC class oil is usually used.

On a note! In addition, for two-stroke engines there is a JASO classification, and for four-stroke engines, SAE30 is still used.

Leading manufacturers of garden equipment themselves develop and produce oils for their equipment. Such lubricant compositions most fully satisfy all the technical and operational characteristics of a specific series of trimmers. For example, for Stihl Lawn Mower FS 5 it is best to use Stihl HP or Stihl HP SUPER oil, for Husqvarna 143R, Husqvarna HP or Husqvarna LS oil is suitable. But for the Patriot brand, the usual mineral oil M-8B is also suitable.

Rules for the preparation of the fuel mixture

For many beginners who have bought a Lawn Mower, the issue of diluting gasoline with oil to prepare a gas mixture becomes a problem. After all, you need to know the proportions and very carefully adhere to them. The instructions for the product usually indicate in what proportion to dilute the components: 1:25 or 1:32, or 1:40, or 1:50. This means that for 1 part of the oil, you need to take 25, 32, 40 or 50 parts of gasoline and mix them.

Of course, it is inconvenient to measure in such categories, therefore it is better to determine how much oil is needed per liter of gasoline using simple mathematical calculations. To do this, divide 1 liter, which is 1000 ml, into a known proportion. The following mixing table is obtained.
