How much oil to add to the trimmer

Fuel mixture: the proportion of oil and gasoline for the chainsaw

The chainsaw engine is the heart of the tool, so it is very important to use a properly prepared fuel mixture..

The fuel mixture for a chainsaw is prepared from two components – oil and gasoline. Chainsaws are equipped with two-stroke engines, so oil is not added to the lubrication system (like in a four-stroke engine), but directly to gasoline. In this case, it is very important to observe the correct proportions of ingredients, of course, in no case try to work on pure gasoline, because in this way you will very quickly “kill” the chain saw.

How To Oil Your Hair Clippers For Peak Performance & Long Life

If we talk about what kind of gasoline to pour into the chainsaw, then it will be optimal to use fuel with an octane rating of A-95, in this case the savings on fuel can turn out to be deplorable. Often European manufacturers indicate that it is possible to use A-90 or A-92 gasoline, but in post-Soviet countries the quality of gasoline is inferior to that of Europe, so in our realities it is better to use better quality gasoline..

As for the proportion of the petrol-oil mixture itself, everything is simple here: you must follow the instructions for the tool. All manufacturers of chainsaws indicate the required ratio in the instruction manual or in the passport of the tool, in addition, the proportions for refueling the chainsaw may differ depending on the model of the chain saw. As a rule, the proportion of oil and gasoline to a chainsaw of famous manufacturers is a ratio of 1:40 or 1:50, which means 1 part of oil for, for example, 40 parts of gasoline. Now arithmetic 1 liter of gasoline = 1000 ml of gasoline, divide by 40 and we get 25 ml of oil. If you follow the same steps to a ratio of 1:50, you get 20 ml of oil per 1 liter of gasoline. As for budget chainsaws made in China, the situation is slightly different. The ratio of gasoline to chainsaw oil made in China 1:25, that is, divide 1000 ml of gasoline by 25, we get 40 ml of oil. The thing is that in branded chainsaws, a solid assembly and the distance between pistons and cylinders in the engine is much less than that of Chinese chainsaws, therefore, the required amount of oil differs almost twice.

Use a regular medical syringe with sufficient volume to measure the correct amount of oil..

Another subtlety – first fill the dry gasoline can with gasoline and then oil. The procedure, on the contrary, is fraught with a low quality fuel mixture, because the oil is more dense, it will stick to the bottom of the canister – what a good mixing here.

Be sure to prepare the fuel mixture in a canister and pour ready-made special fuel into the gas tank! Never cook or mix directly in the fuel tank of your chainsaw!

If you figured out the question of how to breed gasoline for a chainsaw, then on storage conditions and shelf life of the fuel mixture it is worth saying a few words. It is best and easiest to prepare a petrol-oil mixture for 1 liter of gasoline, it is recommended to do this immediately before working with the tool. Chainsaw fuel tanks have a volume of 0.3 to 1 liter. In the conditions of domestic use, the entire volume of the prepared combustible mixture is rarely used in one session, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special canister for gasoline, in a dry, dark place. It is optimal to count that the shelf life of the finished mixture will be 7-10 days. The fact is that the oil on the market now is not synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats up” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.

At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool will stall (so that the saw has a dry carburetor) and now you can leave it until the next operation..

Unsuitable fuel mixture must be disposed of..

The choice of oil and gasoline for the preparation of the fuel mixture for the trimmer

A trimmer, or lawn mower, is an indispensable tool in the household. Moreover, its reliability, efficiency and long service life depend on many factors. For example, the quality of fuel. This means that you need to select the right trimmer oil, observe the proportions when added to gasoline and the rules for refueling the device..

How to dilute gasoline with trimmer oil

Dilute the trimmer gasoline in the correct proportion. An insufficient amount of oil can lead to poor lubrication of the lawn mower components, which contributes to rapid wear.

The correct ratio can be found in the trimmer instructions. Most often it is equal to 1:25, 1:40, 1:50. To obtain such proportions in 1 liter of gasoline, you need to add 40 ml, 25 ml and 20 ml of oil, respectively.

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 you ignore this rule, then the trimmer motor can be unstable, due to which it will quickly fail..

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

This will require:

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

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 trimmer gasoline and mix thoroughly again. Fuel can now be poured into the 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..

In what ratio to dilute gasoline with trimmer oil?

Summer residents, owners of private suburban households for lawn care, weed mowing, buy small mechanization. Prefer combustion engine powered trimmers with a properly diluted gasoline / oil mixture.

Motorized streamers require maintenance, use of a combined fuel. By keeping the ratio of gasoline to oil, it is easy to achieve the performance of lawn mowers.

Algorithm of actions

Fuel quality increases with proper mixing of the mixture components. The question arises before the mowing machine, how to breed, in what sequence. When mixing the components, pay attention to whether the containers are cleanly washed. A tiny slurry can stall the fuel supply to the carburetor. The fuel tank should be filled from a special container with a filter device..

The procedure is as follows. Half of the available gasoline is mixed with the volume of the specified amount of lubricant. This is followed by the mixing process.

When the components acquire a homogeneous consistency, 50% of the remaining fuel is poured into the partially diluted gasoline. This is how it is recommended to dilute the trimmer fuel..

Trimmer Fuel Mixture: Practical Tips

A lawn mower is the same equipment necessary for a suburban or gardening plot, like a tiller or a chain saw. An unpretentious tool in operation, demanding exclusively on the quality of the fuel mixture and its own purity. And if there is usually no misunderstanding with keeping lawn mowers clean, some users periodically have questions about the composition of the fuel. How to dilute gasoline with trimmer oil to keep it running as efficiently as possible? What are the consequences of an excess or, conversely, insufficient amount of oil in gasoline? The answers to these simple questions lie on the surface: you need to understand what role the lubricant plays in the operation of a two-stroke engine.

How and how much to refuel

Filling the trimmer fuel tank is easy. To do this, place the tank so that the lid is on top. The amount of fuel depends on the trimmer model. This information is indicated in the instructions, there is also a mark directly on the tank.

It is strictly forbidden to overfill the tank..

Doing so can cause fuel to overflow into the intake manifold and fuel filter, which could cause engine damage or fuel ignition..

When refueling the trimmer, you must follow the safety measures:

  • try to fill in the liquid so that it does not spill, you can use a watering can for this;
  • if gasoline still spills, then it must be wiped up immediately;
  • the start of the trimmer must be started after the container with fuel is removed to a safe and secure place, preferably at a distance of more than 10 meters;
  • when there is a long break between operations, drain the remaining fuel.

Correct proportion and adherence to mixing and filling techniques will help to extend the life of the trimmer. In this case, it is recommended to choose only a quality product of the corresponding brand.

How to choose the right proportion?

the lawnmower is filled with A-92 gasoline. There are other factory instructions that require gasoline of a different octane number. For example, A-95. The difference in cost is minimal.

The selection of oil does not take liberties. For two-stroke engines, the API sets a specific order:

  • for tillers, lawn mowers, air-cooled mopeds – TA class;
  • engines with a cylinder volume of 200 cm³ – TB class oil;
  • recommends the use of TC class oils for all-terrain vehicles and motorcycles;
  • yacht engines, hydro scooters, motor boats use TD brand lubricant.

From the above list, engine lubricating fluid of the last two positions is not recommended for use with trimmer power units. Letter designations indicate from which petroleum products the lubricating fluid is made.

Attention: If you buy a product on liquid domestic trading floors, take an interest in the labels on the container. The English words self mix say that self-mixing with gasoline is not required. If there is a pre mix phrase on the label, you should prepare the combustible mixture yourself.

How much oil to add to 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 – 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, and 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 lawn mowers, since it depends on how effective and long the operation of such a unit will be..

How to refuel the 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 trimmer uses. In general, prepare:

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

Adding oil to gasoline

Dilution instructions:

  • 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..

Trimmer refueling process

General tips for refueling a 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 in the room – 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 operations of the mower, then the remaining old fuel must be drained.

Choosing a brand of gasoline for trimmers

Select the brand of gasoline for lawn 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 RON 95 unleaded fuel is used to fill the trimmer tank..

Gasoline for fuel mixture

Filling the 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”.

Answers to the question What gasoline is needed for the trimmer and how much oil to pour? under the heading Animals and Plants on the Otvet.expert portal

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 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 are the necessary ones for you data.

We have a 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 trimmer you have. There should be numbers 1:50, 1: 40,1: 20. This is the ratio of oil to gasoline..

Read more:  Which Gasoline To Pour In A Trimmer

Gasoline is needed for the 92nd trimmer, but better than the AI-95. 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 to pour the oil. 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. Take a close look at your own trimmer.

Gasoline for four-stroke engine

Devices with a four-stroke motor are more complex. Oil and gasoline are poured into different containers, from where they are then fed to the engine. For a mower with such a motor, you need AI-92 and AI-95 gasoline. It is better not to use fuel with a lower octane number, because this will lead to unstable engine operation. In addition, do not use a lubricant designed for two-stroke models..

Standard proportions

First of all, it is necessary to take into account the information that the manufacturer recommends, since in the event of a failure of the lawn mowers, 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 trimmer model 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 rates when preparing fuel for the trimmer. When using mineral oils, a ratio of 1: 40 is most often the standard ratio. Therefore, 1 liter of fuel will require 25 ml of such oil, and for a 5-liter canister – 125 ml.

When lawn mowers are working, 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. More 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 lawn mowers 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.

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 mowers’ gas tank. In this way, a homogeneous fuel mixture cannot be obtained. Perhaps it will work, if only then shake the 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 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 much more energy will be required than if it were done the other way around – pour oil into the poured gasoline.
  • Ignoring accurate 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 trimmers are ideal for site maintenance due 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.

Consequences of violation of the ratio

The service life of the motor scooter 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 top up just 1 time. It often happens that this time is quite enough to break the engine..

much, 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. You should 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 fuel tank of the lawn mowers 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 trimmer performance..

Let’s consider the question of the correct refueling of two-stroke lawn mowers, since it depends on how effective and long the operation of such a unit will be..

How to choose for lawn mowers?

For two-stroke engines, lawn mowers 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 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 “likes” 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 lawn mowers of European and American manufacturers in connection with the type of oil. According to the class of oils for household trimmers, it is necessary to use TB oil according to the API classification. For more powerful – vehicle class.
