Oil to gasoline ratio for the lawnmower
Fuel mixture for two-stroke engines
The grass trimmers for grass, which are equipped with a two-stroke motor, do not have a separate system designed for oil supply in order to lubricate the rubbing parts. For this reason, do not fill such engines with pure gasoline, but with a mixture of fuel and motor oil. The latter should be specially formulated for two-stroke engines. The engine will fail prematurely if automobile engine fluid is used.
Fuel mixture preparation for two-roller engines
Gasoline of AI-92 grade should be used to fill the lawnmower with a two-cycle engine. When using AI-95, overheating of the engine and uneven machine operation may be observed. Gasoline and oil should be mixed in the ratio 50:1, where 50 is fuel and 1 is oil. It turns out that 20 ml of oil per 1 liter of fuel is needed.
If the engine is worn out or the tool is operated with a high load, the proportion is 25:1. If there is not enough lubricant, it can cause burrs on the cylinder walls and piston surface. The piston ring will then be damaged, and the engine will seize up. Over-abundance is not that critical, but it can lead to fouling. The piston ring will get caked which reduces the power of the device.
Oil and gasoline proportions for the fuel mix
The service life of your MotoGP engine depends on how accurately you adhere to the manufacturer’s recommended oil to gasoline mix 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 friction parts and surfaces of a variety of parts that are 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 are in contact dryly will start to damage each other. As a result, scuffs, scratches and chips are formed, which will definitely lead to complete or partial failure of the engine (for example, it can jam).
In the opposite case, when too much oil goes into the engine, it does not have time to burn completely, settling on the walls of the cylinder 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 shouldn’t allow the oil to run out of oil even once. It’s better to overfill a little oil 10 times than to underfill just once. It often happens that just once is enough to break an engine.
How to mix gasoline and oil for a chainsaw, for a grass trimmer and for other motorized equipment
The two-stroke motors are already outliving their age. Fewer and fewer 2-stroke machines are being produced but they still exist.
We will consider only the most popular brands.
How to prepare fuel for such machinery.
Always prepare the gasoline-oil mixture thoroughly. Precision in this case is important. If this mixture will be with a small inaccuracy, it can lead to engine failure.
Let’s start with the chainsaw brand Husqvarna
The engine should be filled with 92 petrolNo oil with the designation (TCW) intended for water-cooled boat engines.proportions mixing petrol with oilIf you mix petrol with original Husqvarna oil, the proportion is 2% oil to the amount of petrol or (1:50)
If you mix petrol with non-branded oil marked JASO FB/ISO-L-EGB (according to API classification, these oils are considered low-grade.) then the proportion would be 3% oil to the amount of gasoline or (1:33)
Р mixing recommendations Fill the canister halfway with the required amount of gasoline. Then add required amount of oil and shake it up. After mixing, add the remaining amount of gasoline and shake again. Now you can pour the fuel mix into the tank. Diluted gasoline can be stored for 30 days.
Now let’s look at the STIHL petrol grass trimmer.
The grass trimmer engine for grass runs on 92 gasolineStihl also recommends diluting the gasoline with company oil (STIHL HP, HP Super or HP Ultra)
Proportion for mixing 1:50 (2%) but if you replace the brand oil to oil with a designation API TA (ISO-L-ETA) (in this oil work two-stroke engines of mopeds, mowers and other machines of small power), You should study the packaging with oil. The label will indicate the oil to gasoline ratio (2% or 3%)
Recommendations for mixing First pour the engine oil into the canister, then the gasoline and mix thoroughly.Shelf life is the same 30 days.
Let’s look at two strokes engine with designation f50 and f80.
In certain circles these engines are gaining popularity.These are made in China. They are installed on a bicycle frame. This engine is an exact replica of the engine that was installed on the moped Riga and similar mopeds produced in the USSR.
Preparation of the mixture for this engine is different and uses 2T oil (also mineral oil)
If the motor is running-in, it is recommended to mix oil in the ratio of 1:20 (50 ml of oil per 1 liter of gasoline). After the running-in, the proportion changes. It is necessary to reduce the amount of oil, to 25 ml per liter of gasoline 1:40.
Add the required amount of oil to the gasoline canister and shake
How to dilute petrol with oil for a grass trimmer if you under or overfill the oil
If you have bought a grass trimmer for grass, lawnmower, brush cutter, chainsaw and other types of equipment, you probably know that two-stroke motors are used as power units on them. These engines do not run on pure gasoline like four-stroke engines, but on a mixture of gasoline and oil. In what proportion should you dilute petrol with oil for grass trimmer. this is the question every dacha user asks himself before preparing the tool for work. In this matter we will understand in detail, because the dilution of gasoline with oil for grass trimmer affects the service life of the tool, and improper preparation of the mixture, will lead to rapid wear of the engine. What is dangerous is the excessive or insufficient amount of oil in the gasoline for the grass trimmer for grass:
- If gasoline will be diluted with a lot of oil (above the norm), it will lead not only to a large amount of smoke, but also to the formation of carbon deposits on the cylinder walls and a decrease in power.This fouling will cause wear and tear on the piston, which will be diagnosed by a decrease in its performance
- If the gasoline contains an insufficient amount of oil in the grass trimmer, it is even more dangerous.After all, the working mechanisms of the engine will not be lubricated in sufficient quantity, which will eventually lead to their rapid wear (there is a rapid destruction of the piston rings and jamming of the motor). If there is not enough oil in the gasoline in the grass trimmer, the motor will wear out dozens of times faster
To avoid having to pay for mistakes at the cost of an engine overhaul or buying a new tool, you need to fill the tank with fuel of the correct consistency from the first day. You can find out the ratio in the instruction manual of the tool, because different manufacturers’ models may give different recommendations. Typically this ratio is as follows:
- 1:25 or 40 grams of two-stroke oil per liter of gasoline
- 1 to 40 or 25-30 grammes of grease per 1 liter of petrol
- 1:50. that’s 20 grams of oil added to a liter of gasoline
The standard value is 1 to 50 (it is specified on canisters with oil for two-stroke engines), but you have to rely on it as a last resort, because the manufacturers indicate the recommended proportion value, and if not observed, it reduces the service life of the two-stroke motor.
In addition to the proportions, you must also learn how to prepare the mix. After all, the option of adding oil to the gas tank, is categorically contraindicated, although some do so. If you bought a grass trimmer or lawn mower, you will need the consumables that you will use to prepare the mixture. Instructions for the preparation of the fuel mixture in the grass trimmer for grass is as follows:
- Prepare gasoline and two-stroke oil, following the above recommendations for lubricant and fuel
- In addition, to prepare the mixture, you need to take a container or container. Usually a plastic bottle is used for this purpose, which should be chosen accordingly. It should be clean on the inside. It is not recommended to use a container from milk, beer or other beverages. Mineral water containers are best
- It is very important that the container had a whole value of volume, ie, 1 or 2 liters, so you do not have to calculate how much oil to pour in a bottle of 1.5 liters, 1.3 or 1.25 liters, because it is easy to make a mistake
- You also need a syringe, which is used as a measuring device for dosing the oil. An ordinary medical syringe for 10cc or more is suitable for such purposes. It is desirable that the syringe has an accurate measuring scale
- After preparing the necessary materials, you can begin preparing
Instructions for preparing the fuel mixture in the lawn trimmer:
First, you should fill a plastic container with. The container is filled to 2 fingers not full, so that the oil will fit
After preparing the fuel mixture for the grass trimmer for grass, it remains to fill the tool, and go to work. How to properly fuel grass trimmers for grass, lawn mowers, chainsaws and other types of motor equipment, we will consider in detail.
ДOnly fresh gasoline is used to dilute and apply in the trimmer.
What oil to put in a 2-stroke grass trimmer engine
For gasoline grass trimmer key element that determines the longevity of its operation is lubrication. The two-stroke engine that receives oil together with fuel will serve much longer, if the owner will be selective enough in this matter and will fill only high quality products from reliable suppliers.
In our review you find some of the best oils for 2-stroke trimmers. Rating was based on the lubricant manufacturer’s declared performance. Rating also takes into account the experience of two-stroke owners who have successfully used one of these lubricants for a long time in practice.
What is the ratio of gasoline to oil for a lawn mower
How to dilute gasoline with oil for lawnmower, what kind of gasoline is needed?
Only AI 92 gasoline should be used for lawnmowers.
The ratio is 1 liter of gasoline and 40 grams of oil for two-stroke engines.
First you mix petrol with oil and pour it into the fuel tank.
If you do not mix petrol with oil, but pour petrol first and then oil, the lawnmower will not work and the piston will burn out.
For the preparation of the fuel mixture for the lawn trimmer you should firstly have gasoline of not lower than АI92, secondly a special synthetic oil for two-stroke engines and thirdly a clean container for mixing. Many people simply pour petrol into the tank first, then oil, and shake the mower gently. as a rule the necessary petrol to oil ratio is given in the certificate, but if it is lost, you can mix the components in the proportion 1:40 and you won’t make a mistake. So you need about 25 grams of oil for every liter of gasoline. It may be just the volume of a standard oil cap. By the way extra little increases the smokiness of the mixture when working, and consequently the soot.
Usually manufacturers write in the instructions that gasoline must be with an octane number of at least 90. Regarding the oil and gasoline ratio, again, you need to look at the manual. For one saw 1 to 30, for others. 1 to 40, and, for example, for a Husqvarna chainsaw 1 to 50.
Usually, when you buy a lawnmower, it comes with an instruction manual, which clearly describes the requirements for fuel. But the instruction is not always kept. To refuel your lawn mower, you need to add oil to the gasoline to extend its life. Usually you do it in 1:40 proportions, i.e. you take 1 liter of oil for 40 liters of gasoline. If you cut the amount of gasoline to 1 liter, it turns out that you need 25 ml of oil.
before filling up the lawnmower, you have to mix the mix in a separate fuel can, and only then pour it into the tank.
1:40 figured out how, a liter of gasoline40 ml of oil (you need less to drink).5 years the grasshopper worked. and even with last year’s fuel that wasn’t drained.And then, oh, yeah. You need 25ml.Dilute, pour it in, start it up, stall it. and won’t start again.Changed the carburetor. all in one.That’s funny I already bought a new one.I wanted a two-stroke.But the AL-KO(germany)lies and withers.
You should use 50 ml of internal combustion engine oil per liter of gasoline. You can’t go wrong.
You’d better use AI 93 or AI 95.
Well, the exact proportion and brand of gasoline should be specified in the passport that comes with the product
2-stroke engines are usually used in chain saws. Accordingly, it is necessary to use the fuel mixture, on which a 2-stroke engine runs.
Since the engine has no lubrication system, oil is added to the fuel. If you do not add oil to the fuel, the engine fails very quickly because the rubbing parts run dry and overheat. The piston, piston rings and cylinder are the first to suffer.
In recent years, nearly all manufacturers recommend that gasoline with an octane rating of at least 92 and 2-stroke oil be used in the 40:1 ratio.
If the engine is new or overhauled, you can add a little more oil during the running-in period (25:1). In any case, if you don’t know the manufacturer’s recommendations, it’s better to look at the label on the oil can. If it is a question of changing the proportion, it is better to give more oil. In this case the risk of engine failure will be minimal.
Get the instruction booklet for your ride-on mower, usually the booklet you bought it with. It will definitely say what the requirements are for gasoline. I usually use a 1:40 ratio, but a 1:30 ratio is also possible. So it is 1 part oil and 40 parts gasoline. The oil list on the package also shows the ratio. We buy 92 gasoline, mix it with oil in a separate canister, and then fill the lawnmower and chainsaw with this mixture.
My father dilutes the gasoline in a 1.5-liter plastic bottle for the mower.
He pours the gasoline into the bottle not to the edge, but as it was originally filled with water. Then he pours half a shot of oil in it. There’s 100 grams in that shot glass, so he pours 50 grams of oil on 1.5 liters of 95 gasoline.
I mix my petrol and oil for my mower in a 3 liter jar.
I use 1 capful of oil (the cap of the oil bottle) per 1 liter of 93 or 95 liter of gasoline.
That’s what my dad taught me, and he’s been working with engines for over 40 years.
My mower is 7 years old and it hasn’t broken even once (three times).
Most often, gasoline AI-92 is used for two-stroke engines in gasoline mowers, and the oil to gasoline ratio is 1k40. But if you’re not sure, you can try 1k30. And then watch how the mower behaves for grass and tweak in one direction or another.
Rules for mixing 2-stroke oil with gasoline and diesel fuel
Understanding the role of lubricants in 2t engine operation will allow you to dilute oil with gasoline in the correct proportions. Knowing the consequences of too much or too little oil in the fuel, you will not let your mower or chain saw blend “by eye”.
This instruction applies to all 2t oils and in particular to Agro Formula s 7858 from Mannol, which we also have in stock.
Classification of 2-stroke oils
The API classification divides oils into 4 categories:
- TA. for air-cooled 2t engines used in mopeds, scooters up to 50 cm3 or up to 200 cm3 (oil Naftan 2T-Super);
- TV. used in chainsaws, scooters with a working volume of the cylinder 50-200 cm3 (for example, Mannol 7858 Agro for STIHL);
- TS. used in snowmobiles, motorcycles (Orlen Oil 2t Semisynthetic);
- TD. are used in boat motors, hydraulic scooters, etc.д. (two-stroke oil Sibi Moto 2t, Naftan 2T-Mix).
The division by smokiness, developed by the Japanese (JACO) defines the following categories of oils:
- FA. class with minimum requirements to smoke emissions;
- FB. meet the high smoke emission requirements;
- FC is a class of smokeless oils;
- FD. improved smokeless oils (for yachts, boats).

What kind of gasoline can you put in a grass trimmer for grass? Gasoline of certain AI-95 or AI-92 grade is necessary for blending. Gasoline brand depends on its ignition rate. octane number. The lower the ratio, the faster the gasoline burns and the higher the consumption.
Usually this ratio is as follows:
- 1 to 25 or 40 grams of two-stroke oil per 1 liter of gasoline
- 1 to 40 or 25 to 30 grams of oil per liter of gasoline
- 1 to 50. that’s 20 grams of oil per liter of gasoline
Rules of mixing
To prepare the fuel mixture, you must use a clean and dry container that contains no foreign inclusions or contaminants. Plastic containers are not recommended. After adding liquids in necessary proportions, stir the mixture thoroughly for 2-3 minutes. You cannot do the following:
- Add a small amount of oil directly into the gas tank of the brushcutter, as this will not give a homogeneous mixture;
- Pour oil first, and then gasoline. Because of the difference in densities, this order of adding components also results in an uneven mixture4
- Metering of components “by eye”. You can’t get the exact ratio of gasoline and grass trimmer oil to 1/50 or 1/40 with this approach;
- Use polyethylene bottles as the latter are dissolved by gasoline.
