How to mix oil with gasoline for grass trimmer

Gasoline for lawn mower. what to choose and how to dilute?

To cut the grass in the cottage or in the field, you will need gasoline grass trimmers. They run on gasoline, unlike their electric counterparts. How to dilute gasoline with oil for trimmers, petrol and brush cutters, not many masters know. Step by step instructions on how to prepare the fuel mixture in the trimmer for grass will be useful not only to beginners, but also to experts who may refuel gasoline saws incorrectly.

How to mix

If you don’t have the graduated graduated graduated jerry can that’s included with every noteworthy trimmer, or if you’ve misplaced an old one, use any container that fits your needs. It is better glass or metal. You can also use plastic, but you need to choose a bottle with stiff walls.

The capacity of a container should be a multiple of 1 liter. You can also take a bottle of 1.5 liters, but practice shows that it is not very convenient. You also need a syringe, preferably 20 to 50 milliliters. First fill the container with gasoline, then add a precisely measured amount of oil (by volume). You can’t change the order.

If you have “pre mix” oil the bottle or canister should be closed with a lid and turned upside down several times and shaken violently. If the oil is a “self mix”, it will dissolve on its own. The prepared mixture must be used over the course of a day. If you know how much fuel a grass trimmer uses for a certain amount of work (or time), it’s not hard to calculate the amount of mix. Otherwise, dilute the new fuel before each refill so that there is a minimal amount left before the end of the job.

Why buy grass trimmers?

Comparing with similar mechanisms, give preference in the choice of brushcutters on the following functional indicators:

  • Mobility and low weight of the unit, allowing to carry it over distances, to use in hard-to-reach places for mowing.
  • Universality. the lawnmower is equipped with a node for changing working elements during the machine operation.
  • Constructive simplicity that allows to use the brushcutter for a long time without frequent adjustments.

These, other positive characteristics, give buyers confidence that by purchasing a grass trimmer, make the right choice.

Lubricants classification

The main difference between the principles of two-stroke and four-stroke internal combustion engines (ICE) is that in the case of a four-stroke unit lubrication of the rubbing parts occurs through the crankcase and the oil pump. The power of a four-stroke engine makes it possible to run this unit. A grass trimmer with a two-stroke engine needs a mixture of gasoline and oil to lubricate the entire system (cylinder and pistons, crankshaft, bearing supports). To properly dilute and prepare such a mixture for the grass trimmer, there is a special classification, often presented as a table.

American

Oil in a trimmer does not differ from the lubricants intended for other garden equipment, equipped with a two-stroke internal combustion engine. It has the same composition, additive package and detergent properties. Let us give a closer look at the American classification of oils, or as it is commonly called, API.

  • Group TA is designed for use in trimmers and mopeds with air-cooled two-stroke engine. Claimed volume of devices from 50 cc.cm up to 200 cc.see.
  • TV group is also used in trimmers and other gardening equipment, but with a larger volume of the engine.

Remember that the TA and TV groups are not interchangeable, the ratio of petrol and oil in them may be different.

Japanese

The Japanese also have their own classification of oils. Unlike the American classification generally accepted throughout the world, the Japanese classification is designed primarily for environmental regulations.

  • Group FA is designed for use in trimmers and other devices for countries where emission standards are rather low.
  • FB group is designed for trimmers with a two-stroke engine where legislative requirements to exhaust are significantly increased.
  • FC group for trimmers where requirements for gasoline and oil exhaust are minimal. zero exhaust.

The other classifications are not intended for trimmers.

Guide For Mixing 2 Stroke Fuel For Garden Power Tool

After filling up a grass trimmer, many people put off the leftover mixture in the bottle until the next time. Sometimes that next time doesn’t come soon enough, and stretches into the next year. It is not allowed to keep the ready mix for such a long time because the oil decomposes. After the mixture is prepared, use it up for 1-2 weeks. Also you should not keep the tool with the fuel mixture in the tank for a long time, because the effect will be the same. To prevent unforeseen circumstances, it is advisable to consider the following recommendations for storing the ready-to-use gasoline-oil mixture:

  • Prepare the fuel mixture in the amount that will be used. If you do not know how much fuel you use, then it is better to prepare less
  • If fuel mixture remains in the grass trimmer’s tank (when the tool is hidden until the next season), it must be completely used up or drained
  • Before pouring the mixture into the tank, stir it thoroughly
  • Store the ready mixture in a tightly screwed container, and in a place restricted to sunlight

If you follow all the recommendations, the service life of the grass trimmer will be at least as long as specified in the manual. The use of quality consumables paired with compliance with the recommendations on the preparation of the mixture in the trimmer for grass, will result in a long and efficient service of the gasoline tool.

Rules for pouring the mixture into different engines

All of the above applies to two-stroke engines. In the case of four-stroke engines, you don’t need to dilute and mix anything. the gasoline is poured into the fuel tank, and the oil into the crankcase. It is important to note that you should not add any oil to the brushcutter with a two-stroke engine for the four-stroke engine or for the liquid cooling system. Otherwise, the entire piston system will fail or severe overheating will occur.

Important! For the first filling of a four-stroke engine, no more than 90 ml of oil can be poured into a special tank.

Andrew (Iolanta) Much? Gasoline? 1 liter of oil per 40 kg of slurry.

a lot of oil, 1 liter of benzene per 25, 30 oils

This time I contacted Siberia, asked the guys how much they were counting on their blizzards-2? Answer: 1-50 liters of oil per 50 liters of AI-95, what do seasoned gentlemen think? But of course, I understand that usually after a break.

About the type of oil Shtylivske it can not be prepared for the future, so although I used it for a week, I remember to include it in the manual.

Paul (McLean) 1 / 40ml 1/50ml a lot, I’ll smoke!

If at the rate of 40-50 grams of oil per 1 liter of gasoline, I agree with you on this bankruptcy and ruin, as I wrote above, I correctly recommended the ratio, even if, for example, (1-30. 1.40, 1- 50, where 1 = 1000 ml of oil 30, 40, 50 L = all gasoline: let’s start with this addition, let the ratio be 1-35, we have a canister of 10 L, then 3510 = 350 g of oil for 10 L of gasoline, but this proportion is not very economical, so I specifically went to look at the proportion of 1-50, that is 1 liter oil for 50 liters of gasoline, for example we need to dilute 1 liters of gasoline and calculate how much oil you need? 1000 ml divide by 50 = 20 ml of oil, if my friends I have left somewhere on the right jamb, all have a good mood and a nice day!

The calculated flow rate can be calculated using the formula: for two-stroke 300 grams per horsepower for four-stroke 200 grams. One thought creeps into my scooter’s manual with data on fuel consumption of 7 hp out of 3 liters, it follows that 300 reasonable 7 = 2100 ml, where 0, 900 ml? Help us understand this argument?

Which oil to choose

For the effective operation of the grass trimmer, 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 small engines and air-cooled, but requires frequent changes and may be used only in nice, warm weather;
  • semi-synthetic. suitable for garden equipment with air and liquid type of cooling;
  • Synthetic: with esters in the base, they do not need oil changes very often and can be used at any time of the year.

Oil for 2-stroke engines is characterized by good solubility and peculiarities of complete combustion. For the grass trimmer it is recommended to use a lubricant that is suitable for devices with air cooling system. In most cases it is indicated on the package that the oil is intended for garden equipment and is labeled TA, TV or TC. And the latter is the most preferred.

Often manufacturers of chain saws produce a suitable oil, so you can make the choice easier by selecting a liquid of the appropriate brand.

Features of brushcutter refueling

Depending on the engine, brushcutters are divided into two-stroke and four-stroke models. In the first case, the piston in the internal combustion engine makes 2 strokes per work cycle, and in the second case, it makes 4 strokes. Differences in the engine operating principle cause different approaches to filling the grass trimmer.

Filling up brushcutters with two-stroke engines

Household brushcutter models usually have a two-stroke engine. The lawnmower does not need a lot of power and quickness, so it is quite suitable for the task at hand. Also, this engine is much cheaper and simpler, but it is fueled by a fuel mixture consisting of oil and gasoline. This fuel is filled into the carburetor and discharged into the cylinder as an oil and gasoline mist. The oil thus lubricates all necessary parts. When the engine is in operation, it is burned together with the petrol. But this mixture burns and emits a noxious smell and smoke, which increases the toxicity of the exhaust fumes.

Important! For these brushcutters you need to use a special oil for two-stroke engines, which burns completely without leaving a smudge, and has low evaporation. And in order for it to mix well with petrol it contains 20% of solvent.

Fueling your brushcutter with a four-stroke engine

Four-stroke engines are used in professional brushcutter models. They have plenty of power and can go a long time without stopping and refuelling. Gasoline and oil are also used, but they are filled into separate fuel tanks. It means that oil does not participate in the combustion process, so the exhaust gases are less toxic.

Side note! In addition to better environmental performance and less heat, brushcutter four-stroke engines are also more economical. The engine uses much less fuel. Savings are up to 50 percent for gasoline and 80 percent for oil.
