What oil to pour in brushcutters. What kind of gasoline to fill up??

How much oil to put in your weed trimmer per liter of gasoline?

Gasoline mowers are quite common tools used by garden and homestead owners for mowing grass and making hay. common names for tools are the terms “grass trimmer” and “lawnmower”. The main difference is hidden in the design of the motor. the expensive segment of the devices is equipped with four-stroke models, and the cheap ones. two-stroke. The latter option has advantages, including a small weight, ease of use, as well as low cost.

The most important condition for two-stroke models is the preparation of the fuel mixture, based on the manufacturer’s defined proportion of gasoline and oil. The simplified design of the motor does not provide a separate channel for lubrication, so 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 failure. Let’s understand what composition is required for gasoline trimmers, how to properly prepare the mixture and what it can affect.

The lubrication system of two-stroke and four-stroke engines

Four-stroke engines are equipped with separate lubrication and air-fuel mixture preparation systems.

This is why the pump pumps oil directly to the rubbing surfaces, that is to say the crankshaft bearing and the point of contact of the piston with the cylinder walls.

To do this, the lubricant is poured into a reservoir where it flows through channels to the friction areas.

Also, oil reaches the piston through the crankshaft and connecting rod and washes it off, reducing the temperature and lubricating the cylinder walls.

Two-stroke engines don’t have a separate lubrication system, but they do have a crankshaft bearing which requires a reduction in friction.

in these power units, the fuel-air mixture enters first into the crankcase where the crankshaft bearing is located, and then it passes the piston under the action of suction, cooling it and lubricating the cylinder walls, and enters the combustion chamber.

However, gasoline has no lubricating properties, so such machines are filled with a gasoline mixture, that is, with liquid fuel to which a special oil is added.

The efficiency of fuel mixture lubrication is much lower than that of engine oil, so the service life of a two-stroke engine bearing, and thus the crankshaft and connecting rod is considerably less than that of a four-stroke engine component.

Also, the two-stroke lubrication system has special requirements for the oil, because it has to burn as much as possible in the cylinder and create a minimum of toxic substances.

Oil for brushcuts. how to choose, in what proportions to dilute

Many of you have gasoline tools in the household, for example, in a private home can not do without a chainsaw. You know, to prepare wood for the winter, comes in handy at construction and repair, and in general, it is a very necessary tool. If your country house also has a decent-sized plot, then the grass trimmer or lawn mower, which also run on gasoline, is just necessary to deal with the grass.

Of course, you can buy them electric, but not everyone likes to pull a 30-meter extension cord to mow the area overgrown with grass up to the knee. That’s why most people prefer to work with petrol-powered tools. As you know, you need to add a special oil for two-stroke engines to the gasoline. That’s what we’ll talk about, because this is a very important aspect, if you don’t add oil and add it in wrong proportions, your engine will go “dumpy” very quickly and your way will be to the service center. To avoid all these troubles, add only quality oil in the correct proportions.

The most popular for chain saws, brush cutters and trimmers are products of the well-known company STIHL. It comes in two packages: 1 liter and 100 ml. For those who work a lot, fit a liter bottle, and “once to saw” quite enough small bottle. One liter costs 250, and 10 ml costs 60. The savings are obvious if you get a large one.

You add oil to gasoline in proportion of 1 to 50, so for example you add 100 ml of oil to 5 liters of gasoline. As you can see, a small bottle is great for getting 5 liters of gasoline mix to fill a chainsaw or grass trimmer. The big bottle has special marks on the side so you can see how much oil you have emptied from the bottle. If you bought a big 1 liter bottle, you can buy a 20ml syringe at the drugstore. Very convenient. 1 syringe of oil for 1 liter of gasoline.

We advise you to use a brand-name oil for your machine because this is ideal because it has been developed and tested specifically for STIHL power tools. Note that Stihl has its own brands, such as VIKING (popular models of gasoline trimmers). Also use Stihl oil for them and there will be no problems at all.

If you have more gasoline mixture than you can use, it is best to store the leftovers in a metal canister or glass container. Never store mix in a plastic bottle. Of course, if you use up the leftovers in a couple of days, you can pour the rest of the mixture into a plastic half-cup, but if the mixture will be stored for a long time, then either a canister or a glass container. The thing is that the gasoline mixture corrodes plastic bottle, there are microscopic deposits of plastic in the mixture, and it is very bad for the engine. Keep that in mind if you want your tool to work long and without problems.

The second most popular oil brand is the notorious Hooksvarna. Of course, when you think about it, more people use STIHL chainsaws, at least all my friends and their friends use them for work.

What Happens When You Run Straight, Unmixed Gas in a 2-Stroke, 2-Cycle Engine

But there are those who cherish Husqvarna tools and I understand them, because I personally do not see much difference between Husqvarna and Stihl, both tools are of very high quality. but i have seen happy owners of chainsaws Husqvarna and they say that their saws are great. I have not cut my own saws, but I always listen to what people say. So, if you have Husqvarna gasoline tool, it is better to use a special brand oil for it. Although nothing bad will happen if you dilute the gasoline with Stihl. But since the manufacturer recommends using only its products, we will do so.

You can find liter containers on sale. The bottle is black and stylish, with the same markings on the side as Stihl’s (to know how much oil has been poured out of the bottle). To me, it’s exactly the same quality. It costs 270, a little bit more.

Both oils are of high quality, cost almost the same, each diluted in the ratio of 1 to 50. So feel free to buy any oil, of course, better to take the brand of oil that you have the tool. then everything will be perfect, just as the manufacturer advises. Have a great sawing, mowing grass, and may your power tool work for a long time without breakdowns. on a side note: The submersible pump “Aquarius 3”. my review.

How to Dilute Gasoline with Oil for Grass Trimmer

Dilute gasoline for grass trimmer must be in the correct proportion. Not enough oil can lead to poor lubrication of the lawnmower elements, which contributes to rapid wear. In case the oil will be more than the put will form soot on the pistons and spark plugs. Carbon deposits on moving parts interfere with proper operation and lead to early engine damage.

You can find out what ratio is required for each model of grass trimmer in the user manual provided. The most frequently used mixture for 2-stroke petrol motors of grass trimmers is 50:1, where 50 is a part of petrol and 1 is a part of oil. That is, to 1 liter of gasoline should be added 20 ml of oil. The table will help you choose the necessary ratio.

To measure the proportions correctly, use measuring containers with a milliliter scale. A special double-neck canister is excellent for this purpose; it is designed for mixing and storing oil and gasoline. For example, oil can be taken with a medical syringe without a needle. Before mixing liquids make sure that there is no water, dust or particles of dirt in the container for the ready fuel mixture.

Dilute gasoline with lubricant directly in the fuel tank is not allowed, moreover, the proportion of oil and gasoline must be clearly observed. If you ignore this rule, the operation of the grass trimmer engine can be unstable, due to which it will quickly fail.

Do not use plastic bottles or canisters for this purpose. It is connected with the fact that gasoline tends to dissolve plastic, and that means that some plastic can get into the fuel tank, which can lead to carburetor failure. Although there are special plastic canisters marked “flame”.

  • gasoline;
  • oil suitable for two-stroke engines with air cooling system;
  • canister, preferably made of metal;
  • Mixing tank, also preferably metal;
  • gloves;
  • Respirator.

In addition to protective equipment, do not forget about fire safety rules, because gasoline and motor oil are easily flammable:

  • Conduct the work better outdoors to avoid the accumulation of gasoline fumes in the room;
  • Do not smoke and do not create situations involving the creation of sparks.

Make a mixture of gasoline and oil as follows:

  • Pour 1 liter of gasoline into a container, add half of the required portion of oil. Stir thoroughly, being careful to avoid sources of ignition.
  • Add the rest of the oil to the gasoline of the weed trimmer and mix thoroughly again. Fuel can now be poured into the fuel tank of the grass trimmer.

The mixture can be stored for up to three months, so it is better to dilute the gasoline in such an amount, that it is enough for several uses.

Only high-quality oil may be used for dilution, and it is recommended to buy it only from trusted stores, such as specialized hypermarkets.

How to properly pour diluted fuel into a two-stroke motor

Many people do not follow some important recommendations for pouring fuel into the gas tank of a grass trimmer or lawnmower, which eventually leads to unpleasant consequences. Let’s consider important recommendations on how to properly pour diluted fuel from gasoline and oil into the gas tank of a brushcutter:

  • Prepare a funnel or watering can. Despite the large diameter of the gas tank opening, very often when you try to get into it, some of the fuel spills, which falls on the body of the tool. Trapped fuel on the tool can cause ignition when heated, so it is very important to use a funnel or watering can
  • Before unscrewing the plug, you should thoroughly clean the surface of the tank, because contaminants can get inside, which will cause a rapid clogging of the gasoline filter
  • The works on filling fuel should be done in calm weather or in a secluded place to avoid dust and small grains of sand from getting inside the tank
  • Do not leave the gasoline tank hatch open for a long time, because it can get not only small grains of sand and dust, but also insects
  • Do not inhale gasoline fumes during priming, as they are dangerous to humans. When working with the trimmer, the master must use protective goggles, headphones and a respirator
  • It is necessary to fill the tank up to the mark. If you fill up the tank, when you tighten the cap some of it will spill out. not economical use of fuel. In this case it is better to underfill than overfill

Given these recommendations, you can significantly extend the life of the gasoline tool in question.

This is interesting! It is also recommended to wear protective gloves when mixing and pouring fuel.

What kind of oil to use?

When selecting a lubricant, the following main factors are taken into account

  • provision of engine cooling, protection against thermal shock
  • operation at high rpm and under high loads;
  • resistance to corrosion during standstill periods in winter;
  • absence of carbon and sulfate ash, smokeless;
  • eco-friendliness;
  • good solubility in petrol;
  • storage time of prepared lubricant.

Lawnmower oil must meet the requirements of biodegradability, all-season performance, and economy.

2-stroke engines require a blend in the manufacturer’s recommended oil to gasoline ratio. For four-stroke engines, no mixing is done; the ingredients are poured into separate containers. Lubrication is accomplished by means of oil pipes, a pump, a filter and valves.

To obtain the lubricant, use the types of oils that are most suitable for 2-stroke units:

The fluid contains 5-15% of various additives designed to improve performance, slow down corrosion and stabilize viscosity.

Lawnmowers with 4-stroke engines require a simple automobile fluid, e.g. SAE30 or 10W40, with appropriate technical characteristics. An important characteristic of oils for 4-stroke lawnmowers is their long-term stability. The SF formulation is suitable for almost all makes of car. A frost-proof fluid is used for winter operation. In the chart you can find the right oil grade to fill the tank of a 4-stroke mower for the job at the right temperature. For example, ALKO or Zubr ZMD-4T-M SAE30 mineral engine oil can be used at the following temperatures.5 C° to 35 C°, and semi-synthetic Mannol 4-Takt Plus 10W-40 SL with a temperature range of.25° C to 40° C is suitable for all-season use.

Selection and use of oil

The design of a petrol lawnmower engine differs from a car engine only in the number of cylinders and air cooling.

Its closest analogue is moped motors, because they also have only one cylinder and air cooling. For this reason, gasoline lawnmower engines are suitable for the same oil that is used in cars or mopeds and that corresponds to SAE and API specifications of the manufacturer.

If the manufacturer did not specify SAE and API parameters, then you should be guided by the following values:

Sometimes manufacturers recommend a certain brand of oil, but this is not because it is better suited to a specific engine, but due to a desire to earn money or a partnership commitment, as the manufacturer advertises his products or those of his partners.

At the same time such oil “for lawnmowers” has no real advantages, because car engines operate under much heavier conditions, which means the requirements to the oil for them are much higher.

In addition, it is important to choose the right oil according to the type of base, because it can be:

The choice of base depends on the age of the mower and the presence of a carburetor:

  • 20 years or more. mineral only.
  • 0-20 years, carburetor, mineral or semi-synthetic.
  • 10-20 years old, fuel injection. semi-synthetic.
  • 0-10 years, fuel injection. synthetic or semi-synthetic.

The most popular products for chain saws, brush cutters and trimmers are the well-known STIHL brand. It comes in two packs, one liter and 100 ml. For those who work a lot, a liter bottle is good, and a small bottle is enough for “one time sawing”. A 1 liter bottle costs 250, and a 10 ml bottle costs 60. If you take a large one, the savings are obvious.

Oil is added to petrol in the ratio of 1 to 50, so for example, for 5 liters of petrol you add 100 ml. As you can see, the small bottle is great for getting 5 liters of gasoline mixture to fill a chainsaw or grass trimmer. The big bottle has special marks on the side, by which you can tell how much oil you have poured out of the bottle. If you bought a large 1 liter bottle, then buy a 20ml syringe at the drugstore as well. Very convenient. 1 syringe of oil per 1 liter of gasoline.

STIHL recommends you use a brand-name oil for your machine. it’s ideal, because it has been tested and developed specifically for STIHL power tools. I note that Stihl has its own brands, such as VIKING (popular models of gasoline trimmers). Use Stihl oil for those as well and you won’t have any problems at all.

If you have put more petrol in the mix than you can use, it’s best to keep the remainder in a metal canister or glass container. Never store the mixture in a plastic bottle. Of course, if you use up the leftovers in a couple or three days, you can pour the rest of the mixture into a plastic can, but if the mixture will be stored for a long time, then either a can or a glass container. The whole point is that the gasoline mixture corrodes the plastic bottle, there are microscopic deposits of plastic in the mixture and this is very bad for the engine.

You can find liter containers on sale. It has a black stylish bottle with the same labels on the side as Stihl has (to know how much oil you have poured out of the bottle). To my mind, it’s exactly the same quality. This bottle costs 270, a little bit more.

Both are high-quality oils, the cost is about the same, each diluted in the proportion of 1 to 50. So you can buy any oil you want and it’s better to use the brand of oil you have your tool in. then everything will be perfect, just like the producer says. Good luck with cutting and mowing, and may your chain saw continue to run for a long time without downtime.

How much to charge?

Cultivators, mini-tractors and tillers supplied to the Russian market are mainly equipped with Subaru, BriggsStratton, Honda or their Chinese equivalents. They can be of different capacities and hold different amounts of grease. How to find out how much lubricant to pour out of the canister, so that the 4-stroke engine works in optimum mode, and from the lack of lubrication its parts are not worn out?

Lubricant consumption rates are given in the owner’s manual or in technical documents supplied with the machine. The table below shows individual lubricant consumption rates for the most popular engine models.

Required volume, l
Subaru EX21D (7.0 liters). с.) 0,6
Subaru EH34B (11.0 hp. с.) 1,1
BriggsStratton (8.0 to 13.5 l. с.) 1,2
Honda GX-390 (8.0 to 13.0 l. с.) 1,1

To fill the motor grease can be simple, determining its quantity by the dipstick on the plug. The minimum level is practically limited by the length of the dipstick itself, and the maximum level reaches the threads of the drain hole. You can also orient yourself by looking into the hole in the crankcase.

As a rule, a single axle tractor or snow tugger with 6-8 hp engine can hold about 0,6 l of fluid, and a bit more than 1 l in more powerful units. It is no coincidence that the most popular pouch by manufacturers is the 0.6 liter capacity. That is enough oil to fill medium-powered motor vehicles to the full level, which are most in demand among gardeners and dacha owners.
