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 brushcutter elements, which contributes to rapid wear. If the oil is more than the prescribed amount, carbon deposits will form on the pistons and spark plugs. Carbon deposits on the moving parts of the engine interfere with normal operation and lead to early engine damage.
What proportion is required for a particular trimmer model can be found in the attached instructions. Most often, for 2-stroke gasoline engines of mowers, a fuel mixture is used in a ratio of 50: 1, where 50 is part of gasoline, 1 part of oil. That is, 20 ml of oil should be added to 1 liter of gasoline. The table will help you choose the required ratio.
To correctly measure the proportions, use measuring containers with a milliliter scale. For these purposes, a special double-necked canister is perfect; it is designed for mixing and storing oil gasoline. For example, oil can be drawn with a medical syringe without a needle. Before mixing fluids, make sure that the container for the ready-made fuel mixture is free of water, dust and dirt particles.
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 damage to the carburetor. Although there are special plastic canisters marked “flame”.
This will require:
- Oil suitable for air-cooled two-stroke engines;
- Canister, preferably metal;
- Mixing container, metal is also better;
In addition to protective equipment, do not forget about fire safety rules, because gasoline and engine oil are flammable:
- It is better to carry out work outdoors in order to avoid the accumulation of gasoline vapors in the room;
- Do not smoke and create situations associated with the occurrence of a spark.
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 flame.
- Add the rest of the oil to the trimmer gasoline and mix thoroughly again. Fuel can now be added to the trimmer fuel tank.
The mixture can be stored for no more than three months, so it is better to dilute gasoline in such an amount that it is enough for several uses.
The choice of oil and gasoline for preparing a fuel mixture for a trimmer: dilution ratio table
A trimmer, or a petrol cutter, is an indispensable tool in the household. Over, its reliability, efficiency and long service life depend on many factors. For example, the quality of fuel. This means that you need to select the right trimmer oil, observe the proportions when added to gasoline and the rules for refueling the device.
Which oil to choose
For effective trimmer operation, it is necessary to select oil for two-stroke engines. This is due to the lack of an oil sump in such a device. Depending on the chemical composition of the oil, the following classification is distinguished:
- Mineral based on petroleum distillate, suitable for low-power equipment and with air-type cooling, but requires frequent replacement and can only be used in good weather during the warm season;
- Semi-synthetic suitable for garden equipment with air and liquid cooling;
- Synthetic ones are based on esters, do not require frequent replacement and can be used at any time of the year.
Oil for 2-stroke engines is characterized by good solubility and complete combustion feature. For the trimmer, we recommend using a lubricant that is suitable for air-cooled units. Most often, it is indicated on the packaging that the oil is intended for gardening equipment and is marked TA, TB or TC. And the last one is the most preferable.
If the consumption of engine oil during the summer season is planned to be large due to the presence of a chainsaw, brush cutter, lawn mower in the garden arsenal, then it is advisable to buy 5 liters of oil at a more favorable price. If it is needed only to mix with gasoline and fill the only tool, then 1 liter will be enough.
Often, manufacturers of petrol cutters produce the right oil, so you can make your choice easier if you select a fluid of the appropriate brand.
What gasoline to fill
Gasoline for the trimmer should be chosen unleaded with a stroke number of 92 or 95. As practice shows, AI-80 gasoline can damage the device, which is a questionable economy.
Fuel must be fresh, that is, after purchase, it can be stored for no more than 60 days.
Other factors also affect the quality of the fuel, for example, using a special lubricant for brushcutters and diluting it in a separate container. It is also recommended to use special canisters designed for storing gasoline.
How and how much to refuel
Filling the trimmer fuel tank is easy. To do this, place the tank so that the lid is on top. The amount of fuel depends on the trimmer model. This information is indicated in the instructions, there is also a mark directly on the tank.
Doing so can cause fuel to spill into the intake manifold and fuel filter, which could cause engine damage or fuel ignition.
When refueling the trimmer, you must observe safety measures:
- Try to fill in the liquid so that it does not spill, you can use a watering can for this;
- If gasoline still spills, then it must be wiped up immediately;
- The start of the trimmer must be started after the container with the fuel is removed to a safe and secure place, preferably at a distance of more than 10 meters;
- Drain off the remaining fuel during a long break between operations.
Correct proportion and adherence to mixing and filling techniques will help prolong the life of the trimmer. At the same time, it is recommended to choose only a high-quality product of the corresponding brand.
Oil selection and fuel mixture for petrol cutters
So, have you finally become the owner of a petrol brushcutter 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.
In fact, it doesn’t matter what technique is used, it can be a lawn mower, a brushcutter or a chain saw, they are united by one two-stroke gasoline engine. Unlike the 4T, it does not have an oil sump. It requires the preparation of a special fuel mixture, consisting of gasoline and oil. The resulting liquid is fed directly to the engine (carburetor). In the process of 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 use in 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. Can be used all year round, regardless of temperature conditions. Ideal for demanding, demanding applications 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 feature is the color, which can be green, red or blue. Of course, this does not mean that some lubricant is better, but some 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 two-stroke engines with a volume of 50.200 cm3. Great for lawn mowers, brushcutters, 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 brushcutters, lawn mowers and other 2T garden equipment, a special engine oil is provided for two-stroke engines with an air cooling system and a marking for garden equipment. Do not use lubricant for 2T engines with liquid cooling system. Also not recommended for outboard engines, motorcycles and other equipment.
Oil to gasoline ratio for brushcutters: why is accuracy so important?
We all loved to cheat in childhood, 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 lubricant, 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 the 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 in spite of 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 oil to pour into gasoline for petrol cutters?
Everything is quite simple, with the right 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 the brushcutter, you need to familiarize yourself with the performance characteristics of the product. Proportional ratios can be presented in the following form: 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:
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 petrol cutters 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 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, the 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 have 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 ignite anything.
Gasoline with an octane rating of AI-92 is considered the most popular 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 content becomes higher and a polymerization process occurs, which adversely affects the combustion chamber. The fuel mixture for petrol cutters made of low-quality materials settles in the form of carbon deposits, as a result of which the main components and systems of the engine 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 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 operation and make sure 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 evenly inside the engine. Then, return the candle to its original state. Store equipment in a cool dry place.
Which trimmer oil to choose?
When using a device such as a petrol trimmer, maintenance is particularly difficult. When it comes time to change the oil, many people don’t know which oil to put in the trimmer.
In most of these devices, oil is filled with gasoline. Therefore, the owner must definitely know, using a trimmer, the ratio of gasoline and oil. In most cases, 20 g of oil is taken per liter of fuel. Over, the higher the quality of the fuel, the lower its consumption.
There are also 4-stroke trim engines available. In such oils for trimmers are poured into a separate container, which does not cause any particular difficulties. One of the main advantages of these devices is their low noise, which allows you to work without headphones. Trimmer oils with a four-stroke engine are marked 4T, which must be paid attention to.
What trimmer oils should I use?
Today, there are few people left who use an ordinary braid on their personal plot. This “old-fashioned” method practically does not occur. And many already have no idea how to handle it, sharpen it and rivet it. With the development of technology, devices called trimmers have appeared.
There are two main types of such devices. These are gasoline and electric. From the name it is clear that their main difference is the power source. Each type has both advantages and disadvantages. The advantage of gasoline engines is the absence of a power cord, which does not restrict the owner from moving around the site during work. The electric one needs a 220 V network for power supply. There is no way to do without an extension cord, which will constantly interfere and get confused under your feet.
A modern trimmer that runs on fuel, thanks to the presence of various replaceable heads, has turned from an ordinary scythe into a means of small mechanization with many functions. Having installed the appropriate nozzle, it will not be difficult for the owner to form a crown of shrubs on his personal garden plot. In the snowy winter, it can be used as a snow blower. The very replacement of the working heads of the trimmer does not take much time and can be done with or without the use of a tool.
Advantages and Disadvantages of Gasoline Trimmers
Thus, summing up the above, it is necessary to note the main advantages and disadvantages of gasoline trimmers. The pluses include:
The disadvantages include:
- More weight;
- The amount of noise emitted during operation is greater than that of electrical ones. Despite this, the number of gasoline trimmers in summer cottages is only increasing.
What to look for when choosing an oil?
Modern two-stroke brushcutter engines are fueled with a mixture of AI-92 gasoline and 2T oil. Using a fuel with a higher octane rating will increase the flash point and therefore burn out the lubricant.
Undoubtedly, the best trimmer oil is the one recommended by the manufacturer, but 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 gasoline trimmers of the German manufacturer Stihl, it is necessary to use oils Stihl HP Ultra, Stihl HP, Stihl HP S. A budget substitute can be the products of the Vityaz company, which by their properties are most similar to the recommended material.
Oil selection for petrol cutters
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 small savings can subsequently become a real headache for the owner and, as a rule, high costs.
Two-stroke oil for petrol cutters
The main factor in determining the quality of trimmer oil is the base number. It is this component that excludes oxidation of rubbing parts and slows down their destruction. During operation, the oil gradually loses its alkalinity and becomes oxidized. The optimum acidity level (Ph) should not be less than 8-9 units.
The viscosity of the brush cutter oil also has a great influence on how a gasoline tool works. This indicator determines the ability to operate the trimmer at different temperatures. For example, summer brands of lubricants thicken even with a slight decrease in temperature. Due to the use of petrol cutters exclusively in the spring-autumn period, oil with summer marking would be an excellent option.
The flash point for trimmer oil should be more than 225C, otherwise the oil will burn out quickly and the piston group will be subject to intense wear.
Types of engine oils and their purpose
The choice of oil for the petrol trimmer
Gasoline trimmer engine oil is a lubricant that is used to reduce wear between the rubbing engine components.
The oil composition includes residual hydrocarbons and various additives that improve the properties of the final product. To ensure long-lasting and trouble-free operation of petrol cutters, experts recommend using oils that correspond to this type of engine in their physical and chemical properties.
Today, it is customary to distinguish between three main types of oils according to the way they are obtained:
- Mineral, created in the process of distillation of hydrocarbons;
- Synthetic oils obtained by natural gas processing or synthesis;
- Semi-synthetic, containing improved mineral oil with the addition of some synthetic components.
In order to prevent mixing of various types, the manufacturer adds a dye to the oils, which indicates the difference in the composition of the lubricant.
Trimmer oil: selection and proportions
Oil plays a huge role in the performance and durability of the gasoline trimmer, which protects the parts of the cylinder-piston group from rapid wear.
In order for the petrol brush to please its owner with trouble-free operation, a competent approach to service is required. Currently, it is customary to distinguish between two main types of engine by the number of working strokes:
Working principle of two- and four-stroke engines
- Two-stroke engines, where oil is added directly to the fuel tank;
- Four-stroke engines with separate oil reservoir. The exception in this category is the STIHL 4-MIX engine, which runs on an oil-gasoline mixture, but at the same time has 4 strokes.
However, most trimmers on our market are equipped with powertrains that run on a mixture that has been previously prepared and poured into the fuel tank.
How much oil to pour into the trimmer?
Depending on the number of engine strokes and the type of oil used, the proportions must be strictly observed when preparing the fuel mixture.
Gasoline and oil proportions
So, when preparing fuel with mineral oil, the proportions can vary from 1:25 to 1:35. For high-revving engines with synthetic oil, the lubricant and gasoline portion can be 1:50 or 1:80. Fuel preparation consists in pouring a certain amount of oil into gasoline and then mixing.
For long-term storage of the diluted PVC mixture, the container is not suitable, since when interacting with plastic, the solution loses its properties. Long-term storage of the prepared fuel (more than 2 weeks) must not be allowed, which leads to the formation of an oil film and malfunctions in the fuel system.
Lubricant for trimmer gear. How and how to lubricate?
Occasionally, in the midst of an intense mowing operation, your trimmer will make an unpleasant grinding noise. This complains about the lack of lubrication, the gearbox is the most heavily loaded unit of the device. And soon, these warnings can be followed by a jammed drive.
What kind of lubricant should I use for the trimmer gear?
In the process of operation, the mechanical part of the trimmer is loaded by contact forces on the teeth, resistance reactions from adhering grass (sometimes with dirt), dynamic, shock loads due to constantly changing torque. Lubrication for the trimmer gearbox must fully take into account these features, so the selection of the brand must be strictly individual.
The following factors are taken into account:
- Manufacturer’s brand. Each brand reasonably focuses on its own lubricants (you can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita, etc. The only exceptions are trimmers of domestic production: for example, the Caliber in the user manual does not indicate the brand of lubricant at all
- The viscosity of the lubricant. As you know, all lubricants are divided into three groups of high-viscosity (colloidal systems containing various additives), plastic compounds for universal use and solid lubricants that soften during operation.
- Good adhesion to the surface of gearbox parts, as a result of which the grease is not squeezed out into the gaps or out of the unit.
- The rate of grease consumption by the gearbox. Here you have to rely on your own experience and the recommendations of specialists, since some trimmer manufacturers, relying on their own service centers, do not give clear recommendations at all regarding the period of operation of the gearbox between two lubrications.
Lubricant consumption also depends on the temperature at which it retains its lubricity. When the gearbox is heated to 40C, it is considered that its operating conditions are satisfactory, and there is sufficient lubrication.
It is believed that there is no universal grease for the trimmer gearbox, but this is not entirely true. In fact, a suitable lubricant will be one that contains the following components:
- Lead-free antiwear additives;
- Solid lubricants with the presence of graphite or molybdenum disulfide (the latter is preferable, since the lubricity is fully retained for a wide range of shaft revolutions);
- Only mineral (inorganic!) Oils, highly refined.
These requirements are fully met by Gear Grease OREGON or Champion EP-0 lithium greases, domestic compositions Oleo-Mas, Litol.24, or Azmol 158, as well as those recommended by the manufacturer of a particular trimmer model.
How to lubricate the trimmer gearbox?
In the upper part of the body, where the gear block is installed, there is a technological hole, which is plugged with a screw during trimmer operation. This screw is unscrewed, and 1.52 ml of lubricant is injected into the hole using the spout on the tube. If the lubricant was purchased in a different package, then an ordinary disposable medical syringe is also suitable for this operation.
After that, the screw is installed in its original place. This procedure, regardless of the user’s recommendations, should be performed every 1015 hours of operation of the trimmer in working mode. Other reasons for updating or replacing the gearbox lubricant are the independent performance of minor routine maintenance (for example, cleaning and flushing the gears of the gearbox before the start of the summer season), repairing the unit, preserving the trimmer for the winter, etc.
If the gear unit is disassembled, it is recommended to completely remove the remnants of the old grease from the surface of the parts, even if it does not have any traces of oxidation and contamination. And only then apply new lubricant. After applying the lubricant, it is recommended to rotate the shaft several times by hand, and make sure that the lubricant is evenly distributed over all parts of the gearbox.
When lubricating, pay particular attention to the following elements:
- Flywheel: as a rule, grass remnants stick to its surface intensively, and thickening grass juice creates additional resistance.
- Pawl of the starter coil, which, in the process of turning on the drive, constantly contacts the grooves on the flywheel. In this case, not only mechanical wear occurs, but also mechanochemical corrosion of the flywheel-dog connection, since the materials of this pair are different (the flywheel is aluminum, and the dog is steel).
- Bearings, if their seals are worn out, and through them, the remaining grease is squeezed out. In this case, the unit begins to vibrate intensively when loaded. This happens with Chinese-made trimmers, so in the long run it is worth thinking about replacing the bearing assembly with a better one, for example, from the Swedish company SKF.
