Fuel ratio
If the mixture is diluted correctly, for example, following the instructions below, then the technician will serve you for more than one year without serious technical breakdowns. In this case, fuel consumption will be low, and the result of work will be high. The fuel preparation process must always be the same and constant. It is better to use the same ingredients always, and not change the brand indicated by the manufacturer.
It is NOT worth adding a lot of oil, it can damage the operation of the engine, but you should not save on it either. To maintain the correct proportions Always use the same volumetric container, so as not to be mistaken with the quantity. You can use medical syringes to measure the oil, but some manufacturers together with the oil Provide a set and a measuring container with risks.
The most correct ratio of oil and gasoline is considered to be 1 to 50, where 50 is the amount of gasoline, and the amount of oil is 1. For a better understanding, it is clear that 1 liter is equal to 1000 ml. So, to get a ratio of 1 to 50, divide 1000 ml by 50, we get 20 ml. As a result, only 20 milliliters of oil need to be added to 1 liter of gasoline. To dilute 5 liters of gasoline, you need 100 ml of oil.
In addition to maintaining the correct proportion, you must also follow the mixing technology of the ingredients. In no case should you just add oil to the gas tank. Better to follow the following step by step instructions.
- To dilute the mixture, you must prepare in advance a container in which you will mix gasoline and oil. This can be a clean metal or plastic canister with a volume of 3, 5 or 10 liters, to make it easier to calculate the amount of oil. DO NOT use drinking water bottles for this purpose. they are made of thin plastic, which can dissolve from gasoline. To measure oil Use a special measuring container. But if there is none, then, as already noted, medical syringes with a large dosage will do.
- Pour gasoline into the canister, do not add a couple of centimeters to the full volume. In order not to spill gasoline, take a watering can or insert a funnel into the neck of the canister. Then take the required amount of oil into a syringe or measuring device and pour it into a container with gasoline. It is not recommended to do the opposite. pour gasoline into oil.
- Close the bottle tightly and stir the mixture. If during the preparation of the mixture or its mixing, part of the fuel has spilled out, you must immediately wipe the canister with a dry cloth.
- Be sure to follow fire safety measures. Dilute the mixture away from fire and under no circumstances leave leftover fuel or used materials within easy reach of children.
What gasoline can I fill in the trimmer?
Before determining which gasoline can be put into the trimmer, it is necessary to define some of the concepts used.
- Trim tabs can be with four-stroke or two-stroke engines. Four-stroke trimmers The most powerful and complex in design, the lubrication of its engine parts is carried out by an oil pump. The engine runs on pure gasoline. For two-stroke units. simpler ones. preparation of a fuel mixture consisting of gasoline and oil is required. It is due to the amount of oil in the fuel that the rubbing parts in the cylinder of this engine are lubricated.
- To prepare the mixture, you need a certain grade of gasoline AI-95 or AI-92. The brand of gasoline depends on its ignition speed. octane number. The lower this figure, the faster gasoline burns and the greater its consumption.
Many models of lawn mowers have two-stroke engines running mainly on AI-92 gasoline. The fuel for them must be mixed independently. It is better to pour gasoline into the lawn mower of the brand that is defined for it by the manufacturer, otherwise the trimmer will fail faster. For example, with AI-95 gasoline, the engine will quickly overheat, and when choosing AI-80, the fuel mixture turns out to be of very low quality, therefore the engine will work unstable and with low power.
In addition to choosing a brand of gasoline, when preparing fuel to shift for lawn mowers, you need to use a special oil designed specifically for two-stroke engines. Semi-synthetic and synthetic oils work well for lawn mowers. Semi-synthetic oils are in the middle price range, suitable for such equipment from any manufacturer, they lubricate the necessary engine elements well. Synthetic oils are more expensive, but they will keep the engine running longer. In any case, when buying equipment, you should carefully read the instructions, since sometimes the manufacturer gives recommendations on the use of specific brands of oil.
Gasoline for lawn mowers: which to choose and how to dilute?
For those people who have a summer cottage or a country house, very often there are difficulties with the overgrown grass on the site. As a rule, it is necessary to mow it several times per season and get rid of thickets. A wide range of garden and vegetable garden equipment is currently on the market. One of these assistants can be attributed to a lawn mower, in other words. a trimmer. For effective and long-term operation of such equipment, it is necessary to fill it with high-quality fuel or properly prepared fuel mixtures.
Features of refueling lawn mowers
When the mixture is prepared and ready for use, it must be carefully poured into the fuel tank. Since gasoline is a toxic liquid, safety precautions must be observed when working with it. Work must be carried out in calm weather and away from strangers. And also to pour fuel into the tank, you need to use a watering can or funnel, with which you previously diluted the mixture. Otherwise, the mixture may spill, go unnoticed, and ignite when the engine heats up.
The fuel bank itself must be cleaned of external contaminants and only then Unscrew its cap in order to refuel with the prepared fuel. Once the fuel has been filled, the tank should not be left open, as insects or soil can enter it and clog the fuel filter. You need to fill the fuel in the tank to the indicated mark or less, and then refilled it during operation.
During storage, the container must be tightly closed with a lid. Store fuel in a cool place, out of the sun’s rays. It is worth remembering that during long-term storage of the mixture, the oil liquefies and loses its properties.
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. Use fuel with a lower octane number. This will lead to unstable engine operation. In addition, do not use a lubricant designed for two-stroke models.
Features of refueling a lawn mower
Lawn mowers are divided into two-stroke and four-stroke depending on the engine design. In the first case, the piston in an internal combustion engine makes 2 strokes in one working cycle, and in the second case. 4 strokes. Differences in the principle of operation of the engine cause different approaches to refueling the trimmer.
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 which gasoline the trimmer should work, you can choose it 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 and or another 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 in the equipment manufacturer. And already according to the standard proportions for this manufacturer, select the proportion for a specific model, taking into account the type of oil.
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. In the choice of standard proportions for lawn mowers of European and American manufacturers in connection with the type of oil, we have already told you earlier. According to the class of oils for household trimmers, you need to use TB oil according to the API classification. For more powerful. class TS.
For the ratio of gasoline to oil required for lawn mowers, see the following.
Consequences of violation of the ratio
How accurately you will observe the proportions of the oil-gasoline mixture recommended by the manufacturer depends on the service life of the motor scooter engine. 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, but somewhere it will not be enough at all, the parts touching 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 towards the 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.
Rules for pouring the mixture into different engines
All of the above is relevant for two-stroke engines. In the case of four-stroke engines, it is NOT required to dilute and mix anything. gasoline is poured into the fuel tank, and oil into the crankcase. It is important to know that a two-stroke lawnmower cannot be supplemented with oil that is designed for a four-stroke engine or for a liquid cooling system. Otherwise, the entire piston system will be damaged or severe overheating will occur.
How to choose trimmer oil or types of lubricants
Trimmers and lawn mowers are powered by two-stroke engines, which have a simplified design. Rarely, but there are models of trimmers with 4-stroke motors, which run on pure gasoline. Two-stroke power units do not have a compartment for filling engine oil (oil sump), thereby reducing the weight of the tool and reducing their cost. If the rotating parts of the motor are not lubricated, then in the end they will quickly fail. To prevent this, the trimmer is filled NOT with pure gasoline, but with a mixture with oil. What oil to dilute with gasoline for a trimmer?
To begin with, let’s remember or find out what types of oils are produced by chemical composition:
- Mineral liquids. designed for low power equipment with air cooling. It is the cheapest type of engine lubricant
- Semi-synthetic substances. they are used for equipment that has air and water cooling
- Synthetic. suitable for all types of motors with different types of cooling. They DO NOT require frequent replacement, and this type of lubricant is several times more expensive than mineral and semi-synthetic
From the above it follows that oil with any composition is suitable for a trimmer. mineral water, synthetics and semi-synthetics. Oils with different chemical composition differ in price, therefore, when buying, it is necessary to rely on the recommendations of the tool manufacturer. The instructions indicate advisory information on which types of oils are best to use. If this is the TC-W3 standard, then it is not so important what composition the substance should have. In this case, mineral water, semi-synthetics and synthetics can be diluted with gasoline.
It is interesting! The main thing when choosing an oil is not to fall for a fake, since today you can very often find different types of lubricants for two-stroke engines, which consist mainly of low-quality oil products.
Consequences of filling with a mixture with incorrect proportions
When diluting fuels and lubricants, it is very important to observe the ratio recommended by the lawn mower manufacturer. If there is not enough oil, then scuffs will form on the piston and cylinder, which sooner or later will lead to a breakdown of the piston ring.
And with an excessive amount of oil, coking of the piston ring occurs, as well as the formation of carbon deposits on the piston, on the spark plug, etc. All this leads to heavy wear and tear of equipment and the need for constant cleaning.
The choice of oil and gasoline for the preparation of a fuel mixture for a trimmer: we disassemble thoroughly
For cutting grass in the country or in the field, you will need gasoline trimmers. They run on gasoline, unlike their electric counterparts. How petrol and oil for trimmers, petrol and lawn mowers are diluted, are not known by many masters. Step-by-step instructions for preparing the fuel mixture in the trimmer will be useful Not only for beginners, but also for specialists who may be refueling chainsaws incorrectly.
Mixing the trimmer fuel system is one of the most important tasks for proper trimmer function. From the above, we can conclude that making the mixture with your own hands is not difficult, the main thing is to adhere to simple and clear recommendations. For the convenience of calculating the optimal proportion, it would be best to refer to the table above. It lists all the most popular oil to gasoline ratios.
How to dilute gasoline with trimmer oil
Dilute 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 instructions for the trimmer. 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, 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 carburetor breakdown. 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, also better metal;
- Gloves;
- Respirator.
Make a mixture of gasoline and oil as follows:
- Pour 1 liter of gasoline into a container, add half 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 a few used.

In what ratio dilute gasoline with trimmer oil?
Summer residents, owners of private suburban households for lawn care, weed mowing, buy small mechanization. Preferred trimmers powered by combustion engines fill in a properly diluted mixture of gasoline and oil.
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. Before the mowing, the question arises of 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.
Trimmer Fuel Mix: Practical Tips
A lawn mower is the same equipment necessary for a suburban or garden 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 about keeping lawn mowers clean, some users periodically have questions about the composition of the fuel. How do you dilute gasoline with trimmer oil to keep it working 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.
Practical recommendations for preparing a mixture
Absolutely primitive options should not be considered as oil for a lawn mower, which include autolas of the AC-10 ASZp-10 brands or exotic Chinese and garage origin “masterpieces”. The bulk of lubricants for two-stroke engines are painted by manufacturers in contrasting colors of gasoline: red, green or blue. There are several recommendations proven by many years of practical operation of trimmers.
How much lubricant is required to dilute per 1 liter of fuel if the operating instructions indicate the ratio 1:40, on the fuel tank. 1:25, and on the oil canister. 1:50? The answer is unequivocal. you need to follow the recommendations given on the packaging with the lubricant. Two-stroke engines DO NOT like oil starvation, but you should not oversaturate gasoline with oil either. This provokes the formation of abundant soot deposits on the ventilation ports of the cylinder, which leads to seizure on the piston.
The proportion of how to dilute gasoline with trimmer oils is not difficult to calculate. It is enough to divide the amount of gasoline by the recommended ratio. One liter of gasoline is 1000 ml. To calculate how much lubricant you need to add to get a mixture of 1:50, you need to divide 1000 by 50.It turns out that 1 liter of fuel requires 20 ml of oil. It is convenient to measure the required amount of lubricant with a disposable syringe with a volume of 20 ml.
Do not prepare a large amount of fuel mixture in advance. Gasoline diluted with oil should be stored in a tightly closed container in a cool place. It is safer to store the prepared mixture using steel or aluminum canisters, rather than plastic containers. This is especially true of containers for drinks. Polyethylene terephthalate, which is used in their production, is NOT resistant to most oil products and additives. But plastic is great for sewer systems /
It should be remembered that the resource of the unit, its performance, fuel consumption and comfort when working on the lawn largely depend on how to dilute gasoline with oils for trimmers.
