Oil selection and fuel mixture for lawn mowers
So, have you finally become the owner of a petrol lawn mower or lawn mower? And your imagination is already creating images of how you courageously cope with the dense grass. However, the dream of a “perfect lawn” remains a dream, when the question involuntarily arises: what oil to use and what are the proportions of mixing it with gasoline?
You can find a lot of information on the correct preparation of the fuel mixture on the Internet. This topic is actively discussed on forums and other thematic resources. But, despite such an active discussion, there are many inconsistencies that have to be dealt with..
It doesn’t really matter what technique is used, it could be a lawn mower. lawn mower or chain saw. they are united by one – two-stroke gasoline engine. Unlike the 4T, it does not have an oil sump. To feed it, it is required to prepare a special fuel mixture consisting of gasoline and oil. The resulting liquid is fed directly to the engine (carburetor). During use, all actively working parts are thoroughly lubricated, contributing to trouble-free operation under all operating conditions.
Lawn Mower Engine Oil
Depending on the chemical composition, lubricants are divided into the following main groups:
Mineral. They are made on the basis of oils obtained from petroleum distillates. They are characterized by high viscosity and require frequent replacement. The material is intended for low power appliances with an air cooling system. Recommended for warm weather.
Semi-synthetic. They represent a kind of “golden mean”. They are based on a mixture of mineral and synthetic oils. A similar lubricant can be used in 2T and 4T engines, gardening and other equipment with air and liquid cooling..
Synthetic. They are made on the basis of special synthetic components containing esters. They are characterized by low viscosity and long service life. They can be used all year round, regardless of temperature conditions. Ideal for challenging heavy duty equipment with constant variable performance.
Any two-stroke oil, due to its 20% solvent composition, mixes well with fuel and has the feature of complete combustion. Their second characteristic is their color, which can be green, red or blue. Of course, this does not mean that some lubricant is better, and some is worse. This is done solely so that it is convenient for the user to distinguish oil from pure gasoline..
Classification of engine oils:
The required parameters of oils for 2T engines are prescribed in the requirements of API TC JASO FC, API TC JASO FC ISO GD and API TC JASO FC E-GC. The most widely used classification systems are API. Based on this, 2T engine oils are divided into 4 large groups:
TA. suitable for household appliances with an air cooling system and an engine volume of no more than 50 cm3.
TB – used for more powerful equipment with an air cooling system and a motor volume of 50.200 cm3.
TC. used in technology with high demands for oil quality. It is a high quality lubricant for 50.200 cc two-stroke engines. Great for lawn mowers, lawn mowers, trimmers, chain saws and other garden equipment.
TD. for outboard boat motors with liquid cooling.
Most suitable material for 2T motors of API-TB and API-TC class. However, it is necessary to refer directly to the product passport, where the manufacturer indicates the brand of engine oil recommended for its equipment..
Important! For lawn mowers, lawn mowers and other 2T garden devices, a special engine oil is provided for two-stroke engines with an air cooling system and marked “for garden equipment”. Do not use lubricant for 2T engines with liquid cooling system. Also not recommended oil for outboard engines, motorcycles and other equipment..
Oil to gasoline ratio for lawn mowers: why accuracy is so important?
All of us in childhood loved to “chew”, so the process of preparing a fuel mixture is not only simple, but also interesting. First of all, it is worth considering the fact that the proportions of the mixture may be different. This depends on engine configuration, oil markings and manufacturer recommendations. The fact is that with an insufficient amount of lubrication, the cylinder and piston heat up, which leads to shallow scuffing of all rubbing surfaces and, consequently, to the failure of the cylinder. piston group. Well, in case of its excess, on the contrary, we get coking of the piston ring and the formation of a large amount of carbon deposits.
And even despite the fact that there is a generally accepted mixing ratio of 2% (for every liter of gasoline, 20 ml of lubricant). The proportions in the mixture are still recommended to be kept exactly.
How much to pour oil into gasoline for lawn mowers?
Everything is quite simple, with the correct balance, the engine runs at full capacity, all parts are thoroughly lubricated and do not wear out. As a result, we get a confidently working technique that will last more than one season..
To know how much oil to add to your lawn mower, you need to familiarize yourself with the performance of the product. Proportional ratios can be presented as follows: 1:25, 1:40 and 1:50, which means 1 part of oil for 25, 40 or 50 parts of gasoline.
1 liter of gasoline = 1000 ml
To determine the required amount of oil for a ratio of 1:25, you need 1000/25 and we will get a ratio of 40 ml.
We carry out the same actions for the ratio 1:40 and 1:50:
Lawn Mower Oil Guide: What Type of Lawn Mower Oil Should I Use? | eReplacementParts.com
1:40 (for 1 liter of gasoline 25 ml of oil)
1:50 (for 1 liter of gasoline 20 ml of oil)
To ensure the correct proportion of lawn mower oil, it is recommended to use a special measuring container (not plastic). Eliminate the possibility of dirt and water getting into the fuel mixture. this may affect its quality. It is better to start preparing the mixture with gasoline. Pour it up to the required mark, then add oil. A couple of tilts of the container are sufficient for mixing. The liquid quickly combines and acquires a uniform hue, which, depending on the structure of the oil, can be red, green, blue or other. After that, a properly prepared mixture is poured into the equipment fuel tank..
Before using the equipment, make sure that the tank cap is tightly closed. If you get more fuel, then the remainder can be stored in a special canister or mixing container (no more than 14 days). It is recommended to drain the unused fuel.
Important! Be sure to follow the safety instructions. Mix fluids outdoors to prevent corrosive gasoline fumes from accumulating indoors. Wear gloves and long sleeves. Do not smoke or set anything on fire.
RON 92 gasoline is considered the most popular type of fuel for two-stroke engines. Due to its relatively low cost, it is extremely rarely falsified. Therefore, not one hundred percent, but you can be sure of its quality. It is also permissible to use AI-95 fuel.
As for the storage of fuel, its period should not exceed 3 months. Over time, gasoline loses its properties, the resin becomes higher and a polymerization process occurs, which adversely affects the combustion chamber. The fuel mixture for lawn mowers prepared from low-quality materials settles in the form of carbon deposits, as a result of which the main components and engine systems suffer.
Recommendations for use and storage
The fuel is ready, poured into the fuel tank, the first spurt and the long-awaited start. However, if you want the equipment to work as long as possible, it is recommended to run it in for the first time. To avoid overheating of the engine, it is recommended to adhere to the average load. After the main elements of the system have been thoroughly lubricated, the load can be increased..
Certain rules should also be followed when preparing the braid for off-season storage:
Drain the remaining fuel from the fuel tank and carry out the final run until the fuel is completely depleted. Then, pause the work and make sure that the engine is completely cool..
Unscrew the spark plug carefully and add about 5 ml of lubricant. Pull the starter handle slowly to distribute the oil equally evenly inside the engine. Then, return the candle to its original state. Store equipment in a cool dry place.
Second: what kind of oil to fill in the engine crankcase.
Many people consider famous brands of automobile oil to be the best for use in engines for a tiller (cultivator, snowmobile, electric generator, motor pump, etc.). This is absolutely not the case. Automotive oils are designed to work in water-cooled engines, not air-cooled ones. The boiling point of automotive oils is lower than that of oils that contain special additives for air-cooled engines.
Use oil with quality class SF, SG, SH, SJ, CD or higher. Do not use oil additives. Select oil viscosity based on ambient temperature.
SAE 30 (5 ° C and above) is recommended for temperatures above 5 ° C. May cause difficult starting when used below 5 ° C.
10W-30 (-18 to 38 ° C) is recommended for variable temperatures. This oil provides a cold start to the engine, but can lead to increased oil consumption at temperatures above 27 ° C.
Check oil level more often at elevated air temperatures.
Synthetic 5W-30 (-30 to 40 ° C). Synthetic oil, provides engine operation over the entire temperature range, as well as easy starting and reduced oil consumption.
5W-30 (5 ° C and below) is recommended for work in winter conditions.
FILL ONLY OILS SPECIFIED IN ENGINE INSTRUCTIONS.
Always check the oil level. The level should be up to the last thread of the filler neck in the horizontal position of the engine (as shown in the figure). The fill and drain holes are located at the front and rear of the engine.
Engine oil fill level
On lawn mowers, pay attention to the dipstick. Vertical shaft motor dipstick has marks.
Different engines have different crankcase volumes. If you have a 4, 5.5, 6.5 or 7 hp engine then you need to fill in 600 ml. oils. Engines 7.5 hp 900 ml is poured. In motors with a capacity of 8, 9, 11, 13 and 15 hp. respectively 1.1 l.
Third: starting the engine.
When the engine is started for the first time or cold, there is an increased load on the piston system. High revs can damage the motor. Therefore, it is necessary to start the motor at 1/3 throttle position. And you need to run in at medium speeds.
Instruction for running in and operating a 4-stroke engine
First cause of failure: fuel valve not closed.
When the engine is not running and the fuel valve is open, the carburetor overflows and the spark plug “floods”. Also, gasoline enters the crankcase. And this will lead to overpressure during engine operation and extrusion of the oil seals. This mixture of gasoline and oil will then enter the combustion chamber and through the exhaust valve into the muffler. Gradually the muffler will become clogged with oil residues and the engine will lose traction.
CLOSE FUEL VALVE AFTER OPERATION ALWAYS.
What you need to know about the running-in and operation of four-stroke air-cooled gasoline engines installed on garden, construction and road moto equipment.
Air-cooled four-stroke gasoline engines are widely used in gardening equipment. tillers, motor-cultivators, lawn mowers, snow blowers, motor pumps, mini-tractors, on construction and road-building equipment. gas generators, vibrating plates, vibrating rammers.
READ THE OPERATING INSTRUCTIONS before operating the engine. Unfortunately, many buyers don’t. Therefore, the most elementary questions about the use of the motor arise..
TIP: READ ENGINE OPERATING MANUAL.
The main causes of engine breakdowns
REMEMBER. Engine breakdowns are mainly due to improper operation..
Fourth: how is the engine running in.
Air-cooled engines “don’t like” idling. Start the engine, warm it up for 1-2 minutes. and run in at work. During the break-in, try to adhere to 50-75% of the load and take obligatory breaks in work after 20-25 minutes. After a break, when the engine has cooled down (15-20 minutes), you can continue working again. In this mode, the engine should run for the first 4-5 hours, after which it is imperative to change the oil. Running in finished.
How often to change the oil?
An oil change has a certain interval, which is prescribed for each generator in its data sheet, but there are times when the documentation is not always there or the passport may be in a foreign language. For example, you are unlikely to find a recommendation to go through a run-in. Meanwhile, it is very important for the normal functioning of your station..
Oil change tips:
- If the product is new, the first replacement should take place after 5 hours of operation. This is the very “run-in” that I spoke about. New details seem to “rub” against each other, microroughnesses are smoothed out. At the same time, the oil absorbs all the metalized particles, it becomes waste – black and cloudy. This consistency must be drained and changed;
- The second replacement occurs (on average) – after 20-25 hours of operation. This is the optimal replacement interval, regardless of what loads the generator can handle;
- I recommend performing the third oil change after 50 hours of operation. Subsequent replacements can be at intervals of both 50 and 100 hours. this indicator depends on the manufacturer or the engine installed on the generator. I recommend that you strictly adhere to the specified interval in the technical data sheet of the generator itself..
What kind of oil to fill in a gasoline generator
Expert of the category “Hand and Power Tools”
Many of its components are responsible for the quality of the gasoline generator. How the power plant will work, what current it will supply and whether it will give out a stable voltage depends equally on its mechanisms, and on assembly, and on the quality of the materials used..
And even from the manufacturer. However, there are two leading and defining elements – the alternator and the engine..
If the generator motor is good and works like a clock, then there are no problems. Today I will tell you how to take care of the engine in order to achieve exactly the desired result – long-term operation without failures and repairs..
I always warn inexperienced users that a gasoline engine is not an easy mechanism, it requires a lot of attention, regular inspection and maintenance. One of the most important maintenance steps is oil change..
Any gasoline 4-stroke engine cannot function normally without oil of a certain viscosity, as well as with a small amount or working out. The side effect will be like this. a sharp increase in normal operating temperature, rapid erasure of compression rings, galling on the cylinder, which will lead to premature engine wear or critical breakdown.
In this article I will try to tell you in detail what kind of oil to pour into a gasoline generator, what interval to observe, what brand and viscosity the oil should have.
Choosing a brand of oil
When asked which oil to fill, the best answer is quality. This is in case you love your gene and wish it a long life. Indeed, often premature generator failure is attributed to the manufacturer – they say, the factory defect and the quality is bad. But in fact, you yourself are to blame – pouring bad oil.
Often a conscientious manufacturer clearly indicates which oil for a gas generator should be used in order not to harm the equipment. The brand is registered in the data sheet.
If there is no such information, then I recommend:
The very first step is to shut down the power plant and set it up evenly and securely. Then the used oil for the gasoline generator must be drained, and replaced with fresh.
- We slightly warm up the used oil by turning on the engine for 10-15 minutes. So it will merge more easily;
- We substitute a bucket or other container (1-5 l) under the drain hole;
- Below is a drain plug. It looks different in different oil sump. Sometimes it is a bolt that we do not unscrew completely, but slightly loosen its fastening;
- The oil starts to flow. The process takes some time. You must wait and make sure that all the used oil has drained out;
- After draining, tighten the drain bolt and pour new oil into the tank through the crankcase filler plug;
- Check if the oil level is sufficient. In the crankcase, it must be threaded. We tighten the lid as tightly as possible. The oil change is complete. The device can continue to operate
In no case should you neglect the timely oil change, because this is fraught with engine failure, additional cash costs for its restoration and loss of time. Practice shows that even a person who has never done this can make a replacement on his own in the shortest possible time.

How to mix (dilute) gasoline and oil for 2t engines.
Let’s summarize the above. Use oil for your branded appliances that has been developed or recommended by the manufacturer of that technique. For example, for Stihl FS 55 lawn mowers Stihl HP oil (see Figure 1a) or Stihl HP SUPER oil, for Husqvarna 128R lawn mowers use Husqvarna HP oil (Figure 1b) or Husqvarna LS oil. For 2-stroke engines, do not use 4-stroke engine oils. e.g. 10W30, SAE 30, etc..

Which oil is better for pouring into a lawn mower
What oil Zinaida to use for a 2-stroke engine lawn mowers | Topic author: Love
and in what proportion is it more correct to prepare a mixture for a gasoline trimmer Jeanne.
Yuri Refuel horsemeat Yevgeny from the oil, the lawn mower will go crazy
Antonina with oil for Calm 1: 50
Alla Mineralny Enough
Alena, what does mineral water or synthetics have to do with it? The oil must be FOR 2 STROKE engines.
Valery IS THE SAME ON THE LID OF THE TANK A PROPORTION IS WRITTEN
Lily Mineral two-stroke. Synthetics for environmentally friendly two-stroke engines of technology, which has an environmental class in accordance with the highest European standards.
There on the deafeners of the afterburner systems, grids, etc..
are extremely bad about mineral water, not all burns.
In short, the most expensive models of Calm and Husqvarna with environmental standards for EU countries, completely biodegradable oil, etc..
Inna has a special oil for 2T engines. Litrushka enough horseradish knows how much, do not destroy the technique than not fit.
Christina 20 cc syringe per liter of gasoline. autol oil
Ruslan oil for 2t mix 40cc per liter of gasoline! but about mineral water or synthetics, it doesn’t matter anyway, it burns out
Igor syringe for 20 cubes of oil per liter of gasoline.
Georgy The guys have already spoken about it. for two-stroke engines of lawn mowers and other two-stroke engines of motor vehicles, the oil “Stihl” Elena or Khuzkvarna Ekaterina is best suited. The rest is Lukoil-type oil. for domestic engines of type D16.
It is best to use freshly diluted gasoline for the mechanism. It is allowed to use petrol diluted with oil after storage up to 3 months. In this case, it will be better to dilute fresh gasoline with oil and add Polina to the gasoline from storage..
Oil with gasoline is diluted in a ratio of 1:50 Oksana. That is, 1 liter of oil per 50 liters of gasoline. Accordingly, 0.5 liters of oil per 25 liters of gasoline. From here, you can calculate that 1.5 liters of gasoline requires 25 ml of oil. On new equipment, as well as on old ones, you can dilute a little more oil. for the same 1.5 liters of gasoline. no more than 30 ml of oil Ilya.
Breeding procedure. First, pour oil into a plastic bottle. You can pour through the funnel, you can draw with a disposable Kirill syringe, you can measure the oil with the cap of the oil container itself. For example, Elena bottle cap. this is about 10 ml of oil. There is even a marking, only it is not shown in the photo..
After that, we fill the bottle with fresh AI-92 gasoline, as water is poured into it at the Fedor plant. After that, we twist the cork and shake the bottle several times, and also turn it upside down several times to mix gasoline and oil. After mixing the mixture, we put the bottle on the sediment for 10-20 minutes. After that, the oil-gasoline mixture can be poured into the tank and get to work..
For running-in, it is better to use AI-95 gasoline, and in the future it is better to alternate AI-92 and AI-95 gasolines for the engine. First, 5 liters of AI-95 gasoline are prepared and completely consumed. After that, we work on AI-92 gasoline for about 10-15 liters. After that, we again produce 5 liters of AI-95 gasoline..
The inconvenience here is due to the different quality, additives and octane number of gasoline in the Russian Federation and the same euro-ass.
And further. Please read the instructions carefully before using the device. And especially the point in which it is spelled out: continuous work with the device. 1 tank of fuel, after which the device must cool naturally for at least 20 minutes. After that, refill the fuel and continue working. Otherwise, Pavel is experiencing increased wear and tear, and it is not always possible to start the engine on cold gasoline and it will turn out to be Lydia.
Well. something like this. about.

How much oil do you pour into a two-stroke engine? | Topic author: V
How much oil do you pour into a two-stroke engine?
Sometimes on the instrument they write one ratio of oil to gasoline, and on the oil itself another. So the question is which ratio to use?
On the one hand, the manufacturer, in view of some design features, recommends pouring more oil. And on the other hand, the oil manufacturer says that it should be poured less.
So, for example, I have a 25k1 ratio written on my chainsaw, and 50k1 on a bottle of oil. So, when I burned a liter of gasoline with a ratio of 25K1, the rings on the piston lay down on my piston, a lot of soot formed, the piston had to be disassembled and cleaned. There was also a case when the entire muffler was scored..
What Is The Best Oil For Lawnmowers | Small Engines
So I decided for myself to choose such a ratio as indicated in the oil. After all, oils are of different compositions and you need to follow this indicator and this is the only indicator. And how are you?
By the way, I worked somehow, using ordinary motor mineral oil, the tool works fine. True, I do not know how this affects long-term operation..
Victor (Juta) 20 gram syringe to the eyeballs. Both the saw and the trimmer have been intensively used for 8 years.
Novel (Vihang) Manufacturer to manufacturer difference. So is the oil. Lei at least haddo semisynthetics or motel at the rate and you will be happy. In the Yamaha Axis scooter I pour only Haddo from the very beginning! 11 years and 34 thousand mileage without a single repair. I just change the candles. In the lawn mower I pour both a motul and haddo (when there is something in the leftovers) for 5 years without problems. At work for 5 years for pi. de gone already 3 braids pour some sort of Stihl red and some other crap.
Dmitry and Elena Taranichenko (Ryashentseva) Pour oil on the saw and on the scythe, for boat motors mercury, yamaha 2x tactics. I don’t know the name, but the cost is 1l-1100r. They just gave the canister to the twenty already induced by gasoline. Two years, the norm.
Victor (Juta) It is not recommended to use gasoline that has already been diluted for too long.
Dmitry and Elena Taranichenko (Ryashentseva) Yes, I know, great. But the toad is choking, pour it out.
Roman (Vihang) For the first time I ever hear that you can’t keep a divorced one for a long time! There were a bunch of motorcycles, Java, Izhi, always in the fall filled a full tank of benzyl with oil and stood until spring and nothing. What will become of him.
Dmitry and Elena Taranichenko (Ryashentseva) Usually light fractions of gasoline evaporate, and so.
Roman (Vihang) That’s it, evaporation and that’s it. A friend had a barrel in his garage with gasoline since Soviet times AI-93. At the beginning of the 2000s, we uncorked it, tormented by very strong doubts, for a long time it stood for 10 years, so for sure! But there was no choice, there was no money to refuel, but we had to go! So they filtered it through a watering can with a mesh, folded cheesecloth several times, in addition, I passed the fuel through the filter (there was a very rusty benz) and poured it into the tank and just oh.el! The car began to pull like a beast. From this I conclude that sho in a tightly closed container, even with oil, even without it, you can store nothing with it. P.s about diesel fuel, there was also a case that it was stored for 10-15 years in a capacity of 2 tons. Everything was safely forgotten about it, but I found it and took it for myself and perfectly sold it to my friends, for which they thanked me very much! The diesel was of excellent quality. This is all a myth. I mean that you can’t store! )))
Dmitry and Elena Taranichenko (Ryashentseva) I have nothing against, But when serving the aircraft, there are thousand-capacity tanks, and so they brought fresh fuel, and which left for 2-3 years in storage, then to refueling in units. something like this!
Anatoly (Cherise) The car works much better on old gasoline. I have been holding gasoline in a barrel for at least 2 months for a long time, then I refuel.
Roman (Vihang) I drive on gas, about once a year I fill a full tank of gasoline (it goes to warm-ups in winter and get to the gas station when the gas runs out) and nothing happens to it in the tank, better or worse on sediment gasoline, she goes to say not I can, because when driving on gas, somewhere 20% of power is lost when switching to a benz car rocket
Anatoly (Cherise) On different cars, we checked the settled and fresh gasoline. The difference is at times. The older the gasoline, the better it pulls. The only condition is that gasoline must be stored in an airtight container. This condition is not possible in a gas tank..
Roman (Vihang) What? I have a petal valve on the neck of the gas tank, and the lid is also with a valve, if anything is thrown into the atmosphere, then this is a current in extreme heat.
Anatoly (Cherise) Where did the expansion pipe from the tank go??
Roman (Vihang) I haven’t seen her! There is some kind of tube and it is located like in an iron canister inside, I think that’s what it is! And the tank cover copes with the expansion
Anatoly (Cherise) When gasoline is cooled without an expansion tube, the tank will shrink. Therefore, any machine has a pipe. On cars, you usually need to remove the skin to see it. And in the neck there is an anti-air tube, it is during refueling that gases from the tank are discharged and gasoline does not spill out of the neck.
What kind of oil can be poured into the “nine” transmission
I bought a used “nine” (VAZ-21093). I want to change the oil in the gearbox. They say that even engine oil can be poured into boxes. Is it true?
I bought a used “nine” (VAZ-21093). I want to change the oil in the gearbox. They say that even engine oil can be poured into boxes. Is it true?
Marat Sh., Chernihiv region.
We asked the specialists of TNK Lubrikants Ukraine to answer the question, whose products are supplied for the AvtoVAZ conveyor.
In 1970, for the primary (conveyor) filling and operation of transmission units for VAZ vehicles, a special TAD-17i gear oil was developed and introduced into production, which was made on the basis of Russian base oils with the Anglomol-99 additive package of the Lubrizol company. The TAD-17i oil was an analogue of the W / 90M oil from Fiat and, according to foreign classifications of that time, met the requirements of the SAE 90 and API GL-5 class..
However, in the early 80s, when developing cars of the VAZ-2108/09 family, it was established that the TAD-17i oil did not provide the required durability of the brass synchronizers of the new gearbox for front-wheel drive models. In addition, its use made it difficult to switch gearbox stages. Oils that would correspond to the operating conditions of transmissions of new machines were simply not produced in the USSR at that time. Therefore, for about ten years, engine oil was poured into the checkpoint of “eights” and “nines”, which did not ensure the durability of this unit. The situation changed in 1996, when specialists from the Tyumen Oil Company, together with the Scientific and Technical Center of JSC AvtoVAZ, developed a special oil for gearboxes of front-wheel drive vehicles from Togliatti. It has an SAE viscosity of 80W-85 and meets the API class GL-4 performance. At TNK, this product was originally named Trans KP, and later – Trans Oil. The use of this type of gear oil has made it possible to extend the life of the gearbox and avoid the problems associated with the use of engine oil. The same product in 2002 became the primary fill oil in the gearbox of VAZ cars..
Today AvtoVAZ recommends the use of oils for the gearboxes of its front-wheel drive models that have viscosity according to SAE 75W-90 and 80W-90 and meet the performance properties according to API GL-4.

Lawn Mower Oil
In lawn mowers, which today can be purchased in a wide range, usually a 2-stroke or 4-stroke engine is installed, and accordingly, for each of them it is necessary to prepare a fuel mixture on which they work..
It is not difficult to prepare a fuel mixture. The proportions of gasoline and oil are always indicated in the operating instructions, for example 1 to 32 or 1 to 35. This ratio applies to mineral oil. Synthetic oils are diluted with gasoline in a ratio of 1 to 50. And recommendations for proportions should be followed to the nearest gram!
And if you take a five-liter canister of gasoline, then you need to add only one hundred milliliters of oil to it, and the fuel mixture is ready, and with a low consumption of the fuel mixture by a lawn mower, this amount can be enough for the entire season.
There is an opinion that for a certain brand of lawn mowers you should buy two-stroke oil from the same company, and this is not the case. For any lawn mower with a two-stroke engine, any two-stroke oil is suitable, be it Stihl or Husqvarna, or for four-stroke engines – EFCO SAE oil.
lawnmowers on wheels are equipped with a four-stroke engine, which, unlike a two-stroke engine, also includes an oil sump that lubricates all engine parts. Such units work on gasoline, and it is not necessary for them to prepare a fuel mixture from gasoline and oil, but at the same time it is necessary to change the oils in the crankcase after every fifty hours of operation of the unit. The lack of an oil filter prevents the oil from being cleaned, and therefore it requires such frequent replacement. But fifty hours of work is not a short time, and such a change will not take long. It is better to change the oil in a lawn mower that has worked for a while, so that the oil in it is hot and liquid.
the lawn mower is installed with a slope towards the drain hole. A support is placed under the casing. Having unscrewed the screw-plug, the oil is allowed to drain, after which new oil is poured through the measuring neck. Before changing the oil, the gasoline in the gas tank must be used up. The oil used for lawn mowers is mineral or synthetic, and its viscosity should be within the range. 10W40.
It is necessary to fill the lawn mower with no more “expensive” and better oil, but the one recommended by the manufacturer. If the oil is too thin, it will not stick between parts. The same requirements apply to gasoline. Expensive high-octane gasoline burns longer and can burn a valve, piston or piston rings. Pouring too much oil into the fuel mixture is also not recommended in order not to clog the rings in the engine, which may coke.
