The main thing is to dilute gasoline with trimmer oil in proportion in accordance with the product line.
How to breed petrol with oil for trimmer?
Specifications for the trimmer contain links to recommended fuels and lubricants. At the same time, the octane number of the brand of gasoline is indicated specifically, but in terms of oils there is a lengthy explanation about the need to use a product of a certain manufacturer. For persuasiveness, it is indicated that only if these recommendations are followed, the company extends the guarantee. What is this: marketing ploy Or oils from other manufacturers do not meet the requirements? The answer is in this article.
For what oil for trimmers mix with gasoline
The two-stroke engine has a simple yet extremely efficient design:
- the piston makes a working stroke every second cycle;
- the cylinder is lubricated with oil dissolved in gasoline;
- the removal of combustion products occurs due to compression, without a special mechanism.
All this led to the creation of a family of small engines that have successfully adapted to household and professional equipment:
Due to the design features, it was possible to achieve the desired fuel consumption only on small engines with a power in the range of 15 - 20 hp. This indicator looks especially good in the range of 1 - 5 hp. Here, the low weight and dimensions of the engine fully correspond to the consumption of gasoline.

With an increase in size, the area of the inlet and outlet channels increases. The process of removing gases and supplying fuel deteriorates sharply. As a result, a transition to more effective system combustion of a gasoline mixture, which would provide for the presence of compulsory engine maintenance systems. Four-stroke models have thus intercepted the palm among high-power power units. Combining them into multi-cylinder structures allowed the creation special systems associated with the formation of the composition fuel mixture, lubricants and other things, which favorably affected the consumption of gasoline.

The rubbing elements of the piston and cylinder of a two-stroke engine are lubricated with oil, which is in a certain proportion in the composition of the fuel. Petrol burns out and oil settles on the surface of the cylinder, reducing the friction of the rubbing parts. Lack of lubrication leads to damage to the cylinder, up to jamming. In case of excess, under the influence high temperatures, the thermally modified product is deposited in the annular grooves. Compression drops, and with it, power.
How to mix oil with gasoline
Engine oils are used to add gasoline to the trimmer. Mixing is carried out in a certain proportion. Manufacturers have different volume ratios: from 1 to 50 to 1 to 20. technical specifications there is a link to it. You should be careful with a small fraction of oils. A small inaccuracy leads to oil starvation engine, reduces its resource.
There are products that indicate the proportion of 1 to 20-40. It is better to refuse the use of such a lubricant. The wide range of the mixture speaks of low qualities product. The occurrence of piston rings, with the constant use of such varieties, is practically guaranteed.
Motor oils, type M-8, are added in proportions of 1-20. IN high speed engines their use is undesirable. The mixture cycle is so small that it will cause an overabundance of lubrication in the cylinder. Trimmers have low speed, so they allow the use of low-grade grease. Due to the initially low resource, you can not worry about the coking of the rings. Before there will be a complete wear of the equipment.
It is not important to use the recommended oil or from other manufacturers. The main thing is to spread petrol with oil for trimmer in proportions according to the characteristics of the product. Refusal of service workshops in the guarantee only on the basis of the use of a different brand of lubricant, but with valid parameters, illegal.
A huge role in the performance and durability of a gasoline trimmer is played by oil, which protects parts. piston-cylinder group from rapid wear.
In order for the lawn mower to please its owner with trouble-free operation, a competent approach to maintenance is necessary. Currently, it is customary to distinguish between two main types of engine according to the number of working cycles:
The principle of operation of two- and four-stroke engines
- two-stroke engines where oil is added directly to the fuel tank;
- four-stroke engines with a separate oil reservoir. An exception in this category is the STIHL 4-MIX engine, which runs on an oil-gasoline mixture, but at the same time has 4 cycles of operation.
However, most of the trimmers on our market are equipped with power units working on a mixture previously prepared poured into the fuel tank.
The choice of oil for the gas trimmer
Gasoline trimmer engine oil is lubricant, which serves to reduce wear between the rubbing nodes of the internal combustion engine.
The composition of the oil includes residual hydrocarbons and various additives that improve the properties of the final product. To ensure durable and trouble-free operation of lawn mowers, experts recommend using oils that, in terms of their physical and chemical properties, correspond to this type motor.
Today it is customary to distinguish three main types of oils according to the method of their production:
- Mineral, created in the process of distillation of hydrocarbons;
- Synthetic oils obtained through processing natural gas or synthesis;
- Semi-synthetic, including improved mineral oil with the addition of some synthetic components.
In order to avoid mixing various types the manufacturer adds a dye to the oils, which indicates the difference in the composition of the lubricant.
The choice of oil for lawn mowers
For trimmer engines, it is necessary to choose oils marked "2T", which are used for internal combustion engines with a volume of 50 to 200 cm 3 and are air-cooled. First of all, when buying oil, you should pay attention not to the price, but to the protective properties of the material, since a small saving can subsequently become a real headache for the owner and, as a rule, at high costs.
Two-stroke oil for lawn mowers
The main factor determining the quality of trimmer oil is base number. It is this component that eliminates the oxidation of rubbing parts and slows down their destruction. During operation, the oil gradually loses its alkalinity and becomes oxidized. The optimal level of acidity (Ph) should not be less than 8-9 units.
The viscosity of the brushcutter oil also has big influence on the operation of a gasoline tool. This indicator determines the possibility of operating the trimmer at different temperatures. For example, summer stamps lubricants thicken even at a slight decrease in temperature. Due to the use of lawn mowers exclusively in the spring-autumn period, great option will be oil with summer markings.
The flash point for trimmer oil must be over 225C, otherwise the oil will quickly burn out, and piston group will be subject to heavy wear and tear.
What to look for when choosing an oil?
Modern two-stroke lawn mower engines are refueled with a mixture of AI-92 gasoline and oil marked "2T". Using fuel with higher octane rating will contribute to an increase in the flash point and, as a result, the burnout of the lubricant.
Varieties of oils Stihl
Undoubtedly best oil for the trimmer is recommended by the manufacturer, however, the owner does not always have the opportunity to purchase exactly the “branded” lubricant. Experts recommend Shell Helix Ultra, based on Pureplus technology, which improves the basic properties of the lubricant.
For petrol trimmers of the German manufacturer Stihl, it is necessary to use Stihl HP Ultra, Stihl HP, Stihl HP S oils. Vityaz products, which in their properties are most similar to the recommended material, can become a budget substitute.
How much oil to pour into the trimmer?
Depending on the number of engine cycles and the type of oil used, it is necessary to strictly observe the proportions when preparing the fuel mixture.
Proportions of gasoline and oil
So, when preparing fuel with mineral oil, the proportions can vary from 1:25 to 1:35. To high revving engines with synthetic oil, the portion of grease and gasoline can be 1:50 or 1:80. Preparation of fuel consists in pouring a certain amount of oil into gasoline and then mixing.
Containers are not suitable for long-term storage of a diluted PVC mixture, since the solution loses its properties when interacting with plastic. Long-term storage of prepared fuel (more than 2 weeks) should not be allowed, which leads to the formation of an oil film and malfunctions of the fuel system.
Trimmer oil: choice and proportions was last modified: July 4th, 2018 by Administrator
Hello! I purchased a trimmer Prorab 8406
1. How to dilute gasoline with oil correctly and in what proportion? original oil I didn’t find it from Prorab, I bought Hungsvarna HP oil. The instructions for the trimmer say from third-party oils you can use oils SAE class MIF\4, API TC-TB. In the case of using a different brand of oil, the proportion of the fuel mixture does not change. The standard proportion of the mixture is 1:25.
But in a specialized store, the "specialist" who sold me the Hungsvarna HP oil strongly advised me to dilute it at 1:50 (as it is written on the oil). Actually the question is: if the instructions say to dilute the oil by 1:25, and 1:50 is recommended for oil, then in what proportion should I dilute it? And 1:25 is how much? 40 ml? I won’t lock up the engine if I divorce it at 1:50?
2. How to properly break in the engine? The manual doesn't say anything other than starting and shutting down. Maybe you don't need a wrap? I read that there are such trimmers that you can work immediately after purchase.
3. Do I need to lubricate the gearbox before work, or is there already a factory grease?
Hope you can help, thanks!
1) Gasoline is ALWAYS diluted with oil in the proportion indicated on the can of this oil! With two-stroke products (gas trimmers, chainsaws, etc.) you can use any two-stroke engine oil except two-stroke outboard motors. It is advisable to use oil from normal stores, where the probability of purchase is minimal. fake oil. It is better to take Husqvarna or Stihl oil. Stihl oil must be with a sealed neck. Beware of fakes. There is a risk of spoiling the piston immediately.
2) Two-stroke products are not run-in! REMEMBER THIS PLEASE!
All two-stroke products are high-revving and love to work at full throttle exclusively!
No half gases are allowed! This leads to incomplete exhaust and coking oil deposits piston wall. As a result - badass piston. So full throttle and every 25-30 seconds you do a gas release for 1-2 seconds to give the product a break and return to normal temperature.
3) The gearbox in straight shaft brushcutters must be filled with new grease every 20 hours. Oil comes out naturally during operation. This is done so that dirt, dust, etc., come out with the lubricant. So if you don’t want to get to replace the gearbox, clog it with special gearbox grease every 20 hours. It is not difficult and the whole operation takes no more than 3 minutes. Tubes of lube are sold in every store with garden equipment and cost from 100 to 300 rubles. 1 tube is enough for 3 years.
----
The concept of tool break-in is reduced to work with partial load during the development of the first two or three tanks of fuel. For example, when mowing thin, low grass or sawing dry, not large wood. Under no circumstances should the tool be run in Idling burning several tanks of fuel. As a result of such break-in, carbon deposits are formed on the cylinder windows, on the piston and in the muffler, which negatively affects the engine life.
When choosing a grass care product for a garden or summer cottage, the owner is faced with a choice - what to buy - a lawn mower (electric scythe) or a wheeled lawn mower. The abundance of information on the Internet and the advice of sellers make a perfect mess in the head of a potential buyer, based not only on experience (including negative), but also on prejudices and outright ignorance.
Benzokosa is only for strong men! (like Schwarzenegger).
A benzokosa is a two-stroke gasoline motor with a power of 1-2 hp, located at one end of the tube. And at the other end is a cutting element, a disc or a reel of fishing line. The total weight of this device is several kilograms. And the suspension point is made in such a way that even a fragile girl can handle the brushcutter. The scythe is very well balanced.
Refueling two-stroke engines and preparing the fuel mixture are miracles of alchemy, inaccessible to a mere mortal ....
Two-stroke engines require for their power not just gasoline, but a fuel mixture of gasoline and oil (special for two-stroke engines). This is not a shortage at all, oil for two-stroke engines is sold in any auto parts store and in any place where these same lawn mowers are sold ... Ask the seller and he will bring you to the shelf with these oils. Eyes will run from the choice.
And preparing a mixture of "gasoline-oil" is no more difficult than dressing a salad with mayonnaise. As a rule, the ratio of oil and gasoline in the mixture is indicated on the scythe (or chainsaw) (1:32 - 1:35). This is the ratio for mineral oils. And now for two-stroke engines - still look for them, perhaps among oils for motorcycle engines. For oils in small packages for gardening equipment - practically only synthetic oils. And they have a ratio of 1:50 (as is usually indicated on the package). You should follow the recommendations from the packaging of the oil!
To prepare the fuel mixture, take a canister, for example, 5 liters of gasoline and add 100 ml of oil to it. That's the whole secret. You will be provided with a mixture for the whole season. Not enough - repeat the procedure ... Pour this mixture into the gas tank and no more problems.
For Husqvarna lawn mowers, you need to buy only Husqvarna oil ....
Husqvarna does not have its own oil refineries. This is a completely different business. Therefore, she buys oil for two-strokes at an oil refinery in tanks, packs it in small jars and glues the Husqvarna tag ... And beats the extra 2-3 dollars from the ignorant for this tag. Another firm, for example, "Shtil", buys the same oil at the same plant and glues the "Shtil" tag on the bottles ... And also beats its 2-3 bucks from fools ... Any two stroke oil suitable for any two-stroke engines!
Wheeled lawn mowers – only for perfectly flat lawns…
Nothing like that ... I also thought so on my completely unplanned site. It turned out that the wheeled petrol mower perfectly bends around the terrain. An obstacle for her is perhaps anthills, which are removed with a shovel. And the wheeled lawn mower handles uneven terrain perfectly. Especially if it has height adjustment. Set the maximum - and "check" the site. Where the knife clings to the ground, you can work with a shovel there.
The performance of a wheeled lawn mower is several times higher than a manual lawn mower. And driving it is no more difficult than pushing a baby carriage. You just go and direct it. Especially if the lawn mower is self-propelled. Even kids can handle it.
Wheeled lawn mowers are 4-stroke and their maintenance is as complicated as a car ...
Wheeled lawnmowers usually have four-stroke engines. Fundamental difference four-stroke engines from two-stroke - the presence of a crankcase in which there is oil for lubricating the engine. Therefore, for normal operation A 4-stroke engine does not need to prepare a fuel mixture of oil and gasoline, it is enough to pour only gasoline into the gas tank. This circumstance is presented by some dishonest sellers as a virtue - "they say, you don't have to bother with the preparation of the fuel mixture ...". At the same time, they "cutely" miss such a detail as the need for at least an annual oil change in the crankcase of a wheeled lawn mower. The procedure is not complicated, much easier than changing the oil in a car, but more difficult than preparing the fuel mixture. Generally speaking, the oil in the crankcase of a wheeled lawn mower should be changed approximately every 50 hours of operation. The lawn mower does not oil filter and therefore the oil is not refined there. This leads to more frequent oil changes. On the other hand, 50 hours of lawn mower operation per season is a very long time.
The process of changing the oil in a wheeled lawn mower is simple. Before changing the oil, it is advisable to let the lawn mower run for 10-15 minutes so that the oil warms up and becomes more liquid.
In the design of any lawn mower there is a special screw that closes the drain hole from the crankcase. It is usually located under the filler and measuring neck of the crankcase. (in the photo - indicated by an arrow).
The lawn mower is installed with an inclination to the side drain hole, placing a wooden block or brick under the casing on the opposite side. After that, unscrew the screw - plug. To prevent oil from spilling onto the lawnmower cover, plastic bottle a groove is cut out through which the oil will flow into the substituted container. Gasoline before changing the oil is desirable to develop from the gas tank.
After that, the screw-plug is unscrewed and the oil is allowed to drain by tilting the lawn mower. When the oil drains, the screw is screwed into place. Pour through the measuring neck fresh oil. It is generally recommended to use 10W40, mineral or semi-synthetic oil in lawn mowers.
The danger of "improvement".
An inexperienced owner of garden motorcycles, of course, is inclined to almost idolize the new purchased equipment, up to fetishism. He wants to fill it with better gasoline and more expensive oil. This typical mistake leading to a very rapid failure of equipment!
The point is that this garden equipment made by "flow", i.e. the materials used in it are the most common, and not special. The gaps in the engines are “conveyor-type”, no one rubbed anything there. Therefore, you can not fill more liquid oil than recommended by the manufacturer. It just won't stay in the gaps between the parts.
You can not pour gasoline of a higher grade than recommended. Because gasoline with a higher octane burns longer. And this is fraught with burnout of the valve, piston or rings.
It is impossible to pour more oil into the fuel mixture for two-stroke engines (which would be better lubricated). The saying “you can’t spoil porridge with butter” is completely inapplicable here. Everything should be in moderation here. In general, carefully read the instructions and follow them, and not advice in Internet forums.
In general, maintenance of both 2- and 4-stroke engines is simple and does not require any special skills or effort. For two-stroke engines, it all comes down to the preparation of the fuel mixture and cleaning air filters and ventilation holes. And for four-strokes, maintenance comes down to an annual oil change and cleaning of the air filters. Other annual work to prepare the lawn mower for the season is described in
So, have you finally become the owner of a gasoline mower or lawn mower? And your imagination is already creating images of how you bravely cope with thick grass. However, the dream of a “perfect lawn” remains a dream when the question arises: what kind of oil to use and what 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.
In fact, it doesn’t matter what technique is used, it can be a lawn mower, lawn mower or chain saw, one thing unites them - two-stroke Gas engine . Unlike 4T, it does not have oil sump. For its power, the preparation of a special fuel mixture consisting of gasoline and oil is required. The resulting liquid is fed directly into the engine (carburetor). During use, all actively working parts are thoroughly lubricated, contributing to uptime under any 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. Differ high viscosity and demand frequent replacement. The material is intended for technology low power with the system air cooling. Recommended for use in warm weather.
Semi-synthetic . They represent a kind of golden mean". They are based on a mixture of mineral and synthetic oils. Such a 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 have low viscosity and long term operation. Can be used year-round, regardless of temperature conditions. Ideal for complex equipment designed to work in difficult conditions with constant variable performance.
Any two-stroke oil, due to its 20% solvent composition, mixes well with fuel and has the feature complete combustion. Their second characteristic feature is the color, which can be green, red or blue. Of course, this does not mean that some lubricant is better, but some is worse. This is done solely to make it convenient for the user to distinguish oil from pure gasoline.
Classification of motor oils:
The required oil parameters for 2T engines are specified in the requirements of API TC JASO FC, API TC JASO FC ISO GD and API TC JASO FC E-GC. Most widespread received systems API classifications. Based on this, 2T engine oils are divided into 4 large groups:
TA- suitable for domestic appliances with an air-cooled system and an engine capacity of not more than 50 cm3.
TV- used for more powerful equipment with air system cooling and engine capacity of 50 - 200 cm3.
TC- used in machinery with high demands on the quality of the oil. It is a high quality lubricant for two-stroke engines with a volume of 50 - 200 cm3. Great for lawn mowers, brush cutters, trimmers, chain saws and other garden equipment.
TD- for hanging outboard motors liquid cooled.
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 for two-stroke engines with an air cooling system and the mark " for garden equipment». Do not use lubricant for 2T engines with a liquid cooling system. Boating oil is also not recommended. outboard engines, motorcycles and other equipment.
The ratio of oil and gasoline for lawn mowers: why is accuracy so important?
We all loved to “cheat” in childhood, so the process of preparing the fuel mixture is not only simple, but also interesting. First of all, it is worth considering the fact that the proportions of the mixture can be different. It depends on the engine configuration, oil marking and manufacturer's recommendations. The point is that at not enough lubrication, heating of the cylinder and piston occurs, which leads to shallow scuffing of all rubbing surfaces and, consequently, to failure of the cylinder - piston group. Well, in case of its excess, on the contrary, we get coking piston ring and education a large number soot.
And even despite the fact that there is a generally accepted mixture ratio of 2% (for every liter of gasoline, 20 ml of lubricant). The proportions in the mixture are still recommended to withstand exactly.
How much oil to pour into gasoline for lawn mowers?
Everything is quite simple, with the right balance, the engine runs in full, all parts are thoroughly lubricated and do not wear out. As a result, we get a confidently working equipment that will last more than one season.
To know how much oil to add to a lawn mower, you need to familiarize yourself with operational characteristics products. Proportional ratios can be represented in this form: 1:25, 1:40 and 1:50, which which means 1 part oil to 25, 40 or 50 parts gasoline.
For example:
1 liter of gasoline = 1000 ml
To determine required amount oil for a ratio of 1:25, you need 1000 / 25 and we get a proportion of 40 ml.
We perform the same actions for the ratio of 1:40 and 1:50:
1:40 (for 1 liter of gasoline 25 ml of oil)
. 1:50 (for 1 liter of gasoline 20 ml of oil)
In order for the proportion of oil for the lawn mower to be observed correctly, it is recommended to use a special measuring container (not plastic). Eliminate the possibility of dirt and water getting into the fuel mixture - this can affect its quality. It is better to start preparing the mixture with gasoline. Pour it up to the required mark, then add oil. For mixing, a couple of tilts of the container are enough. The liquid quickly combines and acquires a uniform shade, 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 fuel tank of the equipment.
Before using the equipment, make sure that the tank lid is tightly closed. If you get more fuel, then the rest can be stored in a special canister or mixing container (no more than 14 days). It is recommended to drain the unused fuel to the end.
Important! Be sure to follow the safety regulations. Mix liquids in an open area so that caustic gasoline fumes do not accumulate indoors. Put on gloves and long sleeves. Do not smoke or burn anything.
Petrol
AI-92 octane gasoline is considered the most popular type of fuel for two-stroke engines. Due to the 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 content becomes higher and polymerization occurs, which adversely affects the combustion chamber. The fuel mixture for lawn mowers, prepared from low-quality materials, settles in the form of soot, as a result of which the main components and systems of the engine suffer.
Fuel is ready, poured into the fuel tank, the first jerk and the long-awaited start. However, if you want the equipment to work as long as possible, it is recommended to make its first break-in. In order to avoid overheating of the engine, it is recommended to adhere to the average load. After the main elements of the system are 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 fuel tank and carry out the final run until the fuel runs out. After that, stop work and make sure that the engine is completely cool.
Carefully remove the spark plug and add about 5 ml of lubricant. Slowly pull the starter handle until the oil is evenly distributed inside the engine. After that, return the candle to its original state. Equipment must be stored in a cool, dry place.
Results
We hope that the above general information, will help you navigate the main question - what oil to use for lawn mowers and in what proportions to mix it with gasoline? Having done this action just once, you will understand that it is very simple. You can buy a lawn mower and oil for it in our online store. And remember that only proper care and using high-quality materials, the equipment will serve you as long as possible.
