How much oil to pour into the grass trimmer gasoline

Consumption rates of fuels and lubricants

Fuel consumption for petrol trimmers depends on:

  • engine power;
  • motor volume;
  • the state of the power unit;
  • characteristics of the grass;
  • operator skills.

Therefore, fuel consumption is individual for each engine, and also varies in different situations.

This parameter is measured in various units, the most popular of which are:

  • g / kWh (grams per kilowatt-hour of engine power);
  • l / hp h (liters per horsepower per hour);
  • liters per square meter or weaving (100 m 2).

Manufacturers do not always indicate the real fuel consumption of one trimmer or another, so the owner of such a device will have to find out this parameter empirically. Usually this parameter is within 0.3–2 liters per hundred square meters.

Oil consumption for two-stroke engines is always tied to the amount of fuel and corresponds to the fuel mixture ratio set by the lubricant manufacturer.

The amount of oil for a four-stroke engine is always the same, because it is changed once a season.

What gasoline is suitable for various types of engines?

The motor of any grass trimmer, regardless of type, is designed to run on unleaded AI-92 gasoline.

Nevertheless, the engine can run on other grades of gasoline, for example, AI-76 or AI-95, but this is permissible only for a short time, that is, tens of minutes.

Long-term operation on the wrong fuel will lead to burnout of valves and other problems, after which the power unit will have to be repaired or changed, so you need to know exactly what gasoline can be used to refuel your particular brushcutter model.

Two-stroke

Since the oil for such engines works only for a few moments, after which it burns in the cylinder, it does not require the same durability as is characteristic of the lubricating fluid of four-stroke engines.

In addition, it should have a higher lubricity, because such oil enters the bearing being highly diluted with gasoline.

Since all two-stroke motors of garden equipment operate under approximately the same conditions, the oil for them has no viscosity divisions or any classes.

Two-stroke oil is suitable for a grass trimmer, even if the packaging or container says it is for the following two-stroke devices:

  • lawn mowers;
  • chainsaws;
  • garden equipment.

Complete combustion in the cylinder is also an important condition, otherwise the grass trimmer will heavily pollute the environment, and the smell of its exhaust will be extremely unpleasant.

That is why an improperly formulated fuel mixture produces a thick, dark or bluish exhaust with a pungent unpleasant odor. The same effect appears when the device is operating with a faulty or not tuned engine / carburetor, as well as with strong overgas.

What is the difference between oils for different types of engines?

The different operating principle of the oil system forces the use of lubricants with different properties and characteristics.

In addition, in four-stroke engines, oil serves the whole season, and in two-stroke engines it lubricates the parts, then burns out in the cylinder, which also affects the requirements for it.

Lubrication system for two-stroke and four-stroke engines

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

Therefore, the pump supplies oil directly to the rubbing surfaces, that is, the crankshaft bearing and the point of contact of the piston with the cylinder walls.

For this, the lubricant is poured into a special container, from where it flows through the channels to the areas of increased friction.

In addition, through the crankshaft and connecting rod, oil enters the piston and washes it, lowering the temperature and lubricating the cylinder walls.

Two-stroke engines do not have a separate lubrication system, but they also have a crankshaft bearing that needs to reduce friction.

In such power units, the air-fuel mixture first enters the crankcase, where the crankshaft bearing is located, and then, under the action of vacuum, passes by the piston, cooling it and lubricating the cylinder walls, enters the combustion chamber.

However, gasoline does not have lubricating properties, therefore, such devices are filled with a gasoline mixture, that is, with liquid fuel, to which special oil has been added.

The efficiency of lubrication with a fuel mixture is much lower than that of engine oil, therefore, the service life of the bearing of a two-stroke engine, and therefore of the crankshaft and connecting rod, is noticeably less than that of the same part of a four-stroke engine.

In addition, the two-stroke lubrication system imposes special requirements on the oil, because it must burn as much as possible in the cylinder and form a minimum of toxic substances.

In what ratio should the brushcutter oil be diluted:

In this video, you will find out how much oil you need to add per liter of gasoline to prepare the fuel mixture for the moto grass scythe:

Fuel to Oil Ratio for 2-Stroke Engines

Oil for such engines is supplied in different concentrations, therefore, one part of the lubricating fluid accounts for 20-50 parts of fuel, and the correct ratio is indicated on the packaging or container with oil.

To make the correct mixture, use special containers (cans), which indicate the volume of the contents at different levels.

First, the optimal proportion of both liquids is determined, then the required amount of gasoline is poured (tracked by the marks intended for this) and oil is added to a special discharge of the container, and its amount is also tracked by the marks.

When both liquids reach the desired marks, they are mixed together, shaking the canister thoroughly.

How to fill fuel?

In four-stroke trimmers, pour both fluids into the corresponding holes covered with sealed covers.

If during filling you spill any of the liquids, then remove it with a clean dry cloth, do not leave it on the body.

In two-stroke engines there is only one hole for filling the mixture into the tank.

Remember, a mixture for two-stroke engines must be used within two weeks, after which such a mixture will lose its lubricating properties, so the crankshaft bearing will run dry and dry, which will lead to seizure and expensive repairs.

Fill fuel with a funnel, so there is less chance of spilling, but with enough skill it can be poured directly from a stirring can or even a plastic bottle.

grass trimmer Huter GGT-1500TX belongs to the class of gasoline trimmers, optimally designed for work on lawns and gardens. The GGT-1500TX model received a two-stroke engine, which significantly expands the capabilities of the device, that is, for example, it does not tie the brushcutter to power sources, as is typical for electric trimmers. In this sense, the described model can also be used for processing large areas, since the main factors in this case will be: the availability of a sufficient amount of fuel and the optimal technical condition of the device.

The power of the Huter GGT-1500TX is 1.5 kW, which, along with the features of the cutting tool (line / knife), classifies it as a semi-professional class of such devices. Therefore, the model can be used not only in dachas and country farms, but also in small farms. The GGT-1500TX is great for mowing grass and tidying up areas with small bushes. The grass trimmer weighs 6.78 kg, making it relatively easy to transport, even in a regular passenger car.

How to dilute gasoline with grass trimmer oil

Dilute the grass trimmer gasoline in the correct proportion. An insufficient amount of oil can lead to poor lubrication of the mower components, which contributes to rapid wear. If the oil is more than the prescribed amount, carbon deposits will form on the pistons and spark plugs. Carbon deposits on the moving parts of the engine interfere with normal operation and lead to early engine damage.

You can find out what proportion is required for a particular grass trimmer model from the enclosed instructions. Most often, for 2-stroke gasoline engines of mowers, a fuel mixture is used in a ratio of 50: 1, where 50 is part of gasoline, 1 is part of oil. That is, 20 ml of oil should be added to 1 liter of gasoline. The table will help you choose the required ratio.

To correctly measure the proportions, use measuring containers with a milliliter scale. For these purposes, a special double-necked canister is perfect; it is designed for mixing and storing oil gasoline. For example, oil can be drawn with a medical syringe without a needle. Before mixing liquids, make sure that the container for the ready-made fuel mixture is free of water, dust and dirt particles.

It is unacceptable to dilute gasoline with lubricant directly in the fuel tank; moreover, the proportion of oil and gasoline must be strictly observed. If this rule is ignored, the grass trimmer motor can be erratic, causing it to fail quickly.

It is not recommended to use plastic bottles or canisters for this purpose. This is due to the fact that gasoline has the ability to dissolve plastic, which means that some of the plastic can get into the fuel tank, which can lead to damage to the carburetor. Although there are special plastic canisters labeled “flame”.

  • petrol;
  • oil suitable for air-cooled two-stroke engines;
  • canister, preferably metal;
  • mixing container, metal is also better;
  • gloves;
  • respirator.

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

  • it is better to carry out work outdoors in order to avoid the accumulation of gasoline vapors in the room;
  • do not smoke and create situations associated with the occurrence of a spark.

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. Mix thoroughly, do it with extreme caution, away from sources of open fire.
  • Add the rest of the oil to the grass trimmer gasoline and mix thoroughly again. Fuel can now be added to the grass trimmer fuel tank.

The mixture can be stored for no more than three months, so it is better to dilute gasoline in such an amount that it is enough for several uses.

Stages of starting the grass trimmer for petrol Patriot PT 3355

  • The freshly prepared mixture is poured into the tank.
  • Moves up, to the “cold” position, the choke lever.
  • The ignition on the control knob is set to the “on” position.
  • 5-7 clicks on the primer button are made to fill the carburetor with the mixture.
  • The grass trimmer is placed on a stable surface at a safe distance from objects and people. Avoid touching the trimmer head or cutting blade with the ground.
  • The throttle trigger on the control handle is pressed and locked in this position.
  • Hold on to the grass trimmer with one hand and pull the starter handle with the other hand until it “engages”. At this moment, the handle jerks sharply before starting the engine.

The engine is started with a preliminary pulling of the cord. It is not worth making sharp jerks of a loose cord or pulling the cord all the way because of the high probability of starter breakage.

  • Set the choke lever to the middle position.
  • The starter handle must be pulled several times before starting the engine.
  • Warm up the engine for 5-10 seconds. Move the choke lever down. Pull the throttle trigger to unlock.
  • Smoothly pressing the gas trigger, the engine is brought to maximum speed. Start to work.
  • Mow with a firm grip on the grass trimmer by the ergonomic handles.
  • For a warm engine, the operations described above are performed without pressing the primer. In this case, the air damper is put in the lower position.

The grass trimmer is equipped with a semi-automatic line feed system. When operating at maximum RPM, hit the ground with a light pressure head to increase the length of the line by 2.5 cm.

Answers to the question What gasoline do you need for a grass trimmer and how much oil do you need? under the heading Animals and Plants on the Otvet.expert portal

How to Mix Petrol Oil for 2 Stroke Engine Whipper Snipper / Weed Whacker

Gasoline 92nd. And the proportion of oil is written on the container with oil and depends on its viscosity. In most cases, this is 1 in 50 (20 grams of oil per liter of gasoline).

I’m not very well versed in such things, I only know that the brand of gasoline depends on the type of grass trimmer (in other words, the annotation indicates what brand of gasoline is needed and how much oil is needed), but I also found a forum site where there is for the data you need.

We have a grass trimmer. Usually he takes a duralumin canister and goes for 92 gasoline. How much oil to pour should be written in the trimmer annotation, or on the trimmer itself. Take a close look at the grass trimmer you have. There should be numbers 1:50, 1: 40,1: 20. This is the ratio of oil to gasoline.

Gasoline is needed for the 92nd grass trimmer, but AI-95 is better. Better about everything is written in the annotation. If there is none, then here and there on the tank there should be an indication of the proportion in which the oil should be poured. There is a rule that it is better to overfill the oil than to underfill. 1:20 in some places they write, and in other trimmers 1:40. Stare at Your Own Grass Trimmer.

How much oil to add to grass trimmer gasoline

lawn mowers are a fairly common technique for combating weeds in summer cottages, in household, road and housing and communal services. These devices have two more names. grass trimmer and lawn mower. These units differ in their engines. The more expensive ones have four-stroke engines, all the others have two-stroke engines. Of course, the latter are the most popular among the population, since they are simpler in design, lighter in weight, and much cheaper than their four-stroke competitors. However, two-stroke models are inconvenient in that the fuel mixture for them must be prepared by hand, maintaining a strict dosage between gasoline and oil. In four-stroke analogs, the mixing of these components occurs automatically, you only need to fill the gas tank and oil tank with the corresponding substances. Let’s consider the question of the correct refueling of two-stroke brushcutters, since it depends on how effective and long the operation of such a unit will be.

READ  Selection Of Electric Grass Trimmer

Standard proportions

First of all, it is necessary to take into account the information that the manufacturer recommends, since in case of failure of the brushcutter, you can present your claims to him, and not to a third-party source. If there is no instruction in the passport, and even more so if there is no passport, then we recommend that you look for another model of grass trimmer from a more reliable seller.

For all other cases, when you have a lawn mower model in your hands and there is no way to find out its technical features, there are standard proportions of the most likely fuel mixture components for a two-stroke engine. Basically, these units use AI-92 gasoline and a special synthetic oil, which contains a solvent for better mixing with fuel. Such oil evaporates slowly and has the ability to completely burn out in the cylinder, leaving no carbon deposits.

The standard ratio of synthetic oil to gasoline is 1: 50. This means that 5 liters of gasoline requires 100 ml of oil, and in accordance with this oil consumption per 1 liter of gasoline is 20 ml. Knowing the amount of oil required to dilute 1 liter of fuel, you can easily calculate any rate when preparing fuel for your grass trimmer. When using mineral oils, the ratio of 1: 40 is most often the standard. Therefore, 1 liter of fuel will require 25 ml of such oil, and for a 5-liter canister. 125 ml.

When operating a lawn mower, a person with little experience in operating such equipment will not be difficult to determine and correct the actual amount of oil required for a particular model. You should only pay attention to the exhaust gases (their color, odor toxicity), cycle stability, engine heating and developed power. details about the consequences of incorrect mixing proportions of gasoline and oil can be expected in another section of the article. There are options for brushcutters running on AI-95 gasoline. This should also be considered.

If the manufacturer recommends fuel with such an octane number, then the requirements must be followed so as not to reduce the operating resource of the equipment thereby.

Fuel mixture for two-stroke engines

Grass trimmers, which are equipped with a two-stroke motor, do not have a separate system for supplying oil to lubricate the rubbing parts. For this reason, such devices should be refueled not with pure gasoline, but with a mixture of fuel and engine oil. The latter should be specially designed for two-stroke engines. Application of automotive engine fluid will lead to premature engine failure.

Preparation of a fuel mixture for two-wheel engines

You need to refuel a lawnmower with a two-stroke engine with AI-92 gasoline. When using AI-95, overheating of the engine and uneven operation of the unit can be observed. You need to mix gasoline with oil in a ratio of 50: 1, where 50 is fuel, and 1 is oil. It turns out that 1 liter of fuel will require 20 ml of oil.

If the motor is worn out or the tool is under heavy load, then the ratio is 25: 1. If there is little lubrication, then scuffs will appear on the cylinder walls and the piston surface. Then the piston ring will undergo destruction, causing the engine to jam. An overabundance is not so critical, but it can lead to the formation of carbon deposits. At the same time, the piston ring will coke, which will reduce the power of the device.

Ratios of oil and gasoline for the fuel mixture

How to refuel the grass trimmer

A ready-made mixture of gasoline and oil can be stored for no more than 3 months (pure gasoline is stored less). Dilute enough fuel for several uses of the grass trimmer. In general, prepare:

  • gasoline and oil that is suitable for air-cooled two-stroke engines;
  • metal canister and mixing container;
  • respirator;
  • gloves.

Adding oil to gasoline

  • Pour 1 liter of gasoline into a container of suitable volume and add 1/2 of the required amount of oil.
  • Stir gently while keeping a good distance from open flames.
  • Add the remaining half of the oil to the fuel and stir again.

Grass trimmer filling process

General tips for refueling the grass trimmer with a 2- or 4-stroke engine:

  • Place the fuel tank so that the lid is on top, then fill in the required amount of fuel.
  • Do not overfill the fuel tank. This will lead to one of the problems: overflow into the intake manifold and fuel filter, fuel ignition or engine breakdown.
  • Try to pour the mixture so that it does not spill. To do this, you can use a watering can.
  • If you do spill fuel, wipe it up immediately. Dispose of the cleaning material, do not accumulate indoors. it is fire hazard.
  • The start-up of the device should be started after the fuel canister has been removed at a distance of more than 10 m.
  • If there was a long break between the use of the mower, be sure to drain the remaining old fuel.

Mixing rules

And now about how to mix the components correctly. However, it would be more logical to start with an analysis of common, but absolutely unacceptable mistakes that many owners of this mowing unit “sin” with. The following actions are considered as mixing errors.

  • Adding oil to the fuel already poured into the brushcutter’s gas tank. In this way, a homogeneous fuel mixture cannot be obtained. Perhaps you will succeed if you only shake the grass trimmer for a long time. But it is unlikely that someone will do this, given the severity of the unit.
  • First pour oil into a mixing container, and then add gasoline to it. Gasoline has a lower density than oil, so if it is poured into the oil, it will remain in the upper layer, that is, natural mixing will not occur. Of course, it will be possible to mix later, but it will take much more energy than if it were done the other way around. pour oil into the poured gasoline.
  • Ignoring precise measuring instruments for taking the required quantities of ingredients used. In other words, diluting the amount of oil or gasoline “by eye” is a bad habit when operating motor vehicles.
  • Take empty drinking water bottles for preparation of the fuel mixture. Such a container is made of too thin polyethylene, which can dissolve with gasoline.

Gasoline grass trimmers are ideal for site maintenance thanks to their portability. These models of lawn mowers require periodic fuel changes. The choice of gasoline must be approached competently. It is not worth saving much on the purchase.

Choosing a brand of gasoline for trimmers

It is necessary to select the brand of gasoline for mowers taking into account the manufacturer’s recommendations. If you do not follow them, then the motor will soon break down. Often RON 92 or 95 unleaded fuel is used to fill the grass trimmer tank.

Gasoline for fuel mixture

Filling the grass trimmer with AI-80 gasoline can lead to device breakdowns due to its low technical characteristics. Please note that after purchase, fuel can be stored for no more than 60 days, but it is better to reduce this period.

Polyethylene cans are not used for storage, since static electricity will be generated in contact with the inner walls. An accidental spark will cause an explosion. Although, there are special plastic canisters marked “flame”.

Standard proportions

First of all, it is necessary to take into account the information that the manufacturer recommends, since in case of failure of the brushcutter, you can present your claims to him, and not to a third-party source. If there is no instruction in the passport, and even more so if there is no passport, then we recommend that you look for another model of grass trimmer from a more reliable seller.

If the manufacturer recommends fuel with such an octane number, then the requirements must be followed so as not to reduce the operating resource of the equipment thereby.

Consequences of violation of the ratio

The service life of the motor scooter engine depends on how accurately you follow the manufacturer’s recommended oil-gasoline ratio. The fact is that the fuel mixture enters the cylinders in the form of gasoline-oil mist. And the task of the oil composition is to lubricate the moving and rubbing parts and surfaces of various parts in the cylinder. If it suddenly turns out that there is not enough oil, and somewhere it will not be enough at all, the parts that touch dry will begin to damage each other. As a result, scuffs, scratches and chips are formed, which will certainly lead to complete or partial engine failure (for example, it can jam).

In the opposite case, when too much oil enters the engine, it does not have time to completely burn out, settling on the cylinder walls and turning over time into solid particles. coke, slag and the like. As you might guess, this also leads to engine failure. The most important thing is that you must not allow even a single violation of the proportion in the direction of a lack of oil. It is better to pour a little oil 10 times than not to add just 1 time. It often happens that this time is quite enough to break the engine.

Mixing rules

And now about how to mix the components correctly. However, it would be more logical to start with an analysis of common, but absolutely unacceptable mistakes that many owners of this mowing unit “sin” with. The following actions are considered as mixing errors.

  • Adding oil to the fuel already poured into the brushcutter’s gas tank. In this way, a homogeneous fuel mixture cannot be obtained. Perhaps you will succeed if you only shake the grass trimmer for a long time. But it is unlikely that someone will do this, given the severity of the unit.

  • Ignoring precise measuring instruments for taking the required quantities of ingredients used. In other words, diluting the amount of oil or gasoline “by eye” is a bad habit when operating motor vehicles.
  • Take empty drinking water bottles for preparation of the fuel mixture. Such a container is made of too thin polyethylene, which can dissolve with gasoline.

Considering all of the above, we recommend using the following rules when mixing the fuel mixture for two-stroke engines of the grass trimmer.

  • Use only clean containers made of metal or special plastic for storage of gasoline, oil, ready-made fuel mixture and its preparation.
  • Use a watering can to pour gasoline into a dilution container to avoid spilling, and to add oil. a measuring container with volume risks or a medical syringe for 5 and 10 ml.
  • First, pour gasoline into the canister for preparing the fuel mixture, and then oil.
  • To dilute the mixture, first pour only half of the planned volume of gasoline into the container.
  • Next, add to the gasoline the entire amount of oil required to prepare the mixture.
  • Mix the contents of the dilution container thoroughly. It is best to stir by making circular movements with a tightly closed container. Do not stir the fuel inside the canister with any foreign object, since it is not known what material this object is made of, what reaction it can enter into with the ingredients of the mixture, how clean it is.
  • Add the rest of the gasoline to the mixed mixture and mix thoroughly again.
  • You can fill the mower’s fuel tank with the prepared mixture.

It must be borne in mind that the ready-made fuel mixture should not be stored for more than 14 days, as it loses its properties, stratifies and evaporates, which leads to changes in proportions, and therefore a deterioration in the operation of the grass trimmer.

How to choose for a lawn mower?

For two-stroke engines, brushcutters use AI-92 or AI-95 gasoline. Most often. the first of the named. There is always information about this in the technical data sheet of the product. If, for some reason, it is not known exactly on what gasoline the grass trimmer should work, you can pick it up by testing both brands of gasoline in action. Global changes in the engine will not happen from this, and it is quite possible to determine what kind of gasoline this or that model of the unit “loves” more, according to some factors. This will be shown by the developed power, and throttle response, and engine heating, as well as its stable operation at all speeds.

But it is much more difficult to determine the proportions of oil to a certain volume of gasoline. In this case, you need to know at least something about the manufacturer of the equipment. And already according to the standard proportions for this manufacturer, select the proportion for a specific model, taking into account the type of oil.

You can start selection even by country of origin.

For example, for Chinese low-power trimmers, two ratios are mainly used. 1: 25 or 1: 32. The first is for mineral oils, and the second is for synthetic oils. We have already talked about the choice of standard proportions for petrol cutters of European and American manufacturers in connection with the type of oil. According to the class of oils for household trimmers, you need to use TV oil according to the API classification. For more powerful. class TS.

For information on the ratio of gasoline and oil needed for a lawn mower, see the next video.
