It is a Swedish manufacturer that includes several well-known brands, including Partner (Partner), known for its semi-professional and professional gardening equipment. Husqvarna produces not only machinery, but also high-quality lubricants used in almost all brands of gasoline-powered tools.
The photo below shows a 2-stroke Husqvarna HP oil, which contains special additives that can compensate for the poor quality of fuel, which is not uncommon in our country. After all, the octane number of gasoline purchased at a gas station does not always correspond to the declared one.
This grease is green and contains a semi-synthetic base. It can be packed both in 10-liter containers and in 1-liter containers. The mixture is diluted in a standard ratio of 1:50 (20 g per 1 liter of gasoline). But when the engine has not yet been run in, or work is coming in the cold, the proportion can be increased to 1:40.
How to determine the ratio of gasoline to oil
The fuel mixture used in 2-stroke engines is prepared from a certain amount of oil and gasoline. The latter must have an octane rating of at least 90 and be unleaded. AI-92 fuel is best suited for these purposes.
2 Cycle Vs. 4 Cycle Gas Trimmers: Which is Better for You?
It is not recommended to use gasoline with an octane rating of 95, as it contains many different additives that harm two-stroke engines.
To prepare the mixture, you must use only engine oil from well-known manufacturers. The lubricant should be designed for high-speed engines with an air-cooled system. This component, intended for low-speed engines (moped, motorcycle, snowmobile), must not be used.
When preparing the mixture, it is required to strictly observe the proportion of gasoline and oil. As a rule, it is 1:50, that is, you need to take 100 ml of oil and dilute it in 5 liters of gasoline. This rule changes slightly if the engine or piston system is new and a break-in is required. In this case, the oil-to-gasoline ratio can be 1:40. For running-in, you will need 2-3 full refueling of the unit with a fuel mixture with this ratio. If you dilute the fuel mixture in a ratio of 1:30, then carbon deposits will inevitably form on the piston and inside the cylinder, which, as already mentioned, leads to a breakdown of the entire crank mechanism.
Below is a table that helps you quickly determine the gasoline-oil ratio if you need to prepare a large amount of fuel mixture.
STIHL HP Ultra
The oil belongs to the highest category. It is created on a completely synthetic basis, has a green color and has high lubricating properties, and thanks to salt-free additives it does not create carbon deposits.
The oil was specially developed for the lubrication of engines operating for a long time at high loads and low ambient temperatures, up to 25 ° C. In addition, this lubricant is environmentally friendly. If spilled on the ground, it will decompose by 80% in 21 days. The grease is packaged in bottles of 100 ml and 1 l.
What parts of a chainsaw need oil
If you look closely at a working chainsaw, you will immediately notice its main moving part. the saw chain, which slides along the tire during sawing. Since the law of friction still exists, both parts gradually wear out. To slow down this process, it is customary to use chain oil specially formulated to lubricate saw chains.
Chainsaws can be equipped with both four-stroke and two-stroke engines. In 4-stroke units, the crankset is lubricated with oil in the engine crankcase. Two-stroke engines differ slightly in their design and operating principle. Gasoline for this type of drive enters directly into the space under the piston, where the crank mechanism is located, which has several bearings and bushings that need lubrication. Therefore, oil for two-stroke engines of chainsaws is added to gasoline so that it, getting on the rubbing parts of this block, lubricates them.
Overview of manufacturers of oils for internal combustion engines
Among the manufacturers that produce the best two-stroke oils, we can confidently name 2 leaders. these are Husqvarna (Husvarna) and STIHL (STIHL). The companies produce not only conventional mineral oils, but also synthetic lubricants designed for 2-stroke engines operating in severe conditions.
All about choosing your chainsaw oil
The resource of any chainsaw, no doubt, depends on the quality of its maintenance and operation. The most important requirement for this unit is the timely lubrication of all its moving parts. Chainsaw oil is available in different types, namely: motor and chain oil. The motor is poured into the internal combustion engine, and the chain is intended for the saw chain. Let’s figure out how to choose the right oil for a chainsaw.
Choice of oil for chain lubrication
Remember to check the amount of oil in the oil tank after each refueling of the chainsaw with the fuel mixture. In a chainsaw, an oil pump is responsible for delivering lubricant to the tire on which the saw chain slides. Normally, filling both tanks. fuel and oil. should be done at the same time. Chain oil must be poured into a suitable tank up to the neck. Otherwise, it may run out before fuel, which will lead to overheating of the chain and bus.
Chainsaw chain oil must be designed specifically for this purpose. The use of other lubricants is ineffective and reduces the life of not only the saw, but also the tires of the machine. This is due to the fact that the chain oil contains adhesive additives, due to which the lubricant literally “sticks” to the chain. This property of the oil reduces its consumption, as a result of which the lubrication of the chainsaw bar and the saw chain is improved, and their service life increases.
Also an important parameter of chain lubrication is its density. If you are going to use a lubricant that is not intended for chainsaws, you may notice that oil leaks during operation or after stopping the unit. This fact suggests that the grease is too liquid. In addition, the liquid lubricant will quickly scatter in all directions and, accordingly, quickly run out.
When using a chainsaw in winter, you must use oil designed for low temperatures to lubricate the chain, otherwise the oil pump will fail. Therefore, the grease remaining in the tank must be replaced with a low-temperature one.
Leading manufacturers of gas powered tools such as STIHL, Husqvarna, Makita, Bosch and Oregon chainsaw accessories manufacturer recommend special highly adhesive oils, including biodegradable ones. But oils of well-known brands have only one drawback. for 1 liter and above. In addition, the grease in the reservoir can thicken over time and clog the channels. For this reason, it has to be drained, and this already increases the consumption. But despite this, we have to admit the fact that only the use of special lubricants can extend the service life of the chainsaw.
Types of engine oils and their purpose
Gasoline Grass Trimmer Engine Oil is a lubricant used to reduce wear between engine friction components.
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 the lawn mower, experts recommend using oils that correspond to this type of motor in terms of their physicochemical 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 different types, the manufacturer adds a dye to the oils, which shows the difference in the compositions of the lubricant.
Choosing a lawn mower oil
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.
The main factor in determining the quality of your grass 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 optimal 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 of the grass trimmer to operate at different temperatures. For example, summer brands of lubricants thicken even with a slight decrease in temperature. Due to the use of the lawn mower exclusively in the spring and autumn period, oil with summer marking would be an excellent option.
The flash point for grass trimmer oil must be more than 225C, otherwise the oil will burn out quickly and the piston group will be subject to intense wear.
Choosing the oil and preparing the fuel for the grass trimmer
A huge role in the performance and durability of the gasoline grass trimmer is played by oil, which protects the parts of the cylinder-piston group from rapid wear.
In order for a lawn mower to please its owner with trouble-free operation, a competent approach to maintenance is required. Currently, it is customary to distinguish between two main types of engine by the number of working strokes:
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 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.
What to look for when choosing an oil?
Modern two-stroke brushcutter engines are fueled with a mixture of AI-92 gasoline and oil marked “2T”. Using fuels with a higher octane rating will increase the flash point and therefore burn out the lubricant.
Undoubtedly, the best oil for the grass trimmer 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 Vityaz products, which in their properties are most similar to the recommended material.

Choosing a brand of gasoline for trimmers
It is necessary to select the brand of gasoline for mowers taking into account the manufacturer’s recommendations. If you do not follow them, then the motor will soon break down. Often RON 92 or 95 unleaded fuel is used to fill the grass trimmer tank.
Gasoline for fuel mixture
Filling the grass trimmer with AI-80 gasoline can lead to device breakdowns due to its low technical characteristics. Please note that after purchase, fuel can be stored for no more than 60 days, but it is better to reduce this period.
Polyethylene cans are not used for storage, since static electricity will be generated in contact with the inner walls. An accidental spark will cause an explosion. Although, there are special plastic canisters marked “flame”.
Engine oil is a special blend of solvent and friction-reducing additives. They form a certain viscosity and do not allow the composition to thicken when the temperature is lowered. Usually oils are specially colored in different colors: green, red or blue. This allows them not to be confused.
Please note that they may vary in composition, so petrol trimmer oil will be labeled “for gardening”. In addition, it may still differ in marking: “2T” or “4T”. The first is two-stroke oil, which is poured into the corresponding engine. And the second is intended for pouring into the crankcase.
In addition, you should be aware that under no circumstances should mineral and synthetic oils be mixed due to the fact that they have a different base.
Fuel mixture for two-stroke engines
Grass trimmers, which are equipped with a two-stroke motor, do not have a separate system for supplying oil to lubricate the rubbing parts. For this reason, such devices should be refueled not with pure gasoline, but with a mixture of fuel and engine oil. The latter should be specially designed for two-stroke engines. Application of automotive engine fluid will lead to premature engine failure.
Preparation of a fuel mixture for two-wheel engines
You need to refuel a lawnmower with a two-stroke engine with AI-92 gasoline. When using AI-95, overheating of the engine and uneven operation of the unit can be observed. You need to mix gasoline with oil in a ratio of 50: 1, where 50 is fuel, and 1 is oil. It turns out that 1 liter of fuel will require 20 ml of oil.
If the motor is worn out or the tool is under heavy load, then the ratio is 25: 1. If there is little lubrication, then scuffs will appear on the cylinder walls and the piston surface. Then the piston ring will undergo destruction, causing the engine to jam. An overabundance is not so critical, but it can lead to the formation of carbon deposits. At the same time, the piston ring will coke, which will reduce the power of the device.
Ratios of oil and gasoline for the fuel mixture
Now let’s try to figure out how to choose a quality gasoline grass trimmer oil. The main feature to look out for is the base number. This moment excludes the oxidation of the parts that have friction and slows down their deformation as much as possible. The more this compound is used, the faster it loses its alkalinity and becomes more oxidized. The optimal indicator of acidity (PH) is a value of at least 8-9 units.
The second important factor that also has a major impact on the performance of a gasoline grass trimmer is the viscosity of the oil. This characteristic determines the ability to use the device at different temperatures. Summer brands of oils begin to thicken already with a minimal decrease in temperature.
But given that these grass trimmers are usually used in the fall and spring, it is best to use just the oil with summer markings.
The third point, the importance of which should not be underestimated, is the flash point. This indicator should not be less than 225 degrees. Otherwise, the composition will burn out very quickly and the load on the piston group will begin to increase, which will cause its accelerated wear. Also, 4-stroke oil is not suitable for 2-stroke. Namely, the latter type of motors is used in the vast majority of gas mowers.
If we talk about manufacturers, then you can make a small rating that will allow you to navigate the formulations offered by various manufacturers. For example, STIHL offers high-quality synthetic and mineral oils that have already proven themselves as an excellent solution at any time of the year.
Shell Helix Ultra oil is considered very good. Experts note its high characteristics and excellent indicators of alkalinity and viscosity. In addition, the products of such brands as Oleo-Mac, Motul, Hammerflex, Echo are considered worthy. If we talk about the products of domestic brands, then you should pay attention to Lukoil oil. Its price is several times lower than foreign counterparts, but at the same time it has high quality and good technical characteristics.
In general, the ideal solution would be a synthetic or semi-synthetic oil labeled TV or TA.
A quality oil that can be poured into a gasoline grass trimmer must meet a number of requirements and regulations to ensure reliable operation and performance. The oil should:
- provide an increase in wear resistance for various elements (in particular, the gearbox is especially susceptible to this);
- to ensure the formation of smoke and exhaust gases is as low as possible;
- do not allow premature ignition;
- mix well with gasoline when exposed to low temperatures;
- have good viscosity and flow characteristics in various temperature ranges;
- be as safe as possible in terms of environmental impact.
As mentioned, two-stroke engine oil will differ from four-stroke engine oil. It has higher power, which is why fuel for it is obtained by mixing a certain amount of gasoline and oil. For each brushcutter, the ratio will be different. You can find out its meaning in the instructions for the device. These proportions must be observed with maximum accuracy. When adding additives, take into account the type of motor.
If mineral oils are used, mixing should be somewhere in the ratio of 1: 25, 30 or 35, depending on the type. If we are talking about a synthetic analogue, then the proportion will be 1: 50 or 80. That is, a certain amount of oil dissolves in the volume of gasoline.
Gasoline for four-stroke engine
Devices with a four-stroke motor are more complex. Oil and gasoline are poured into different containers, from where they are then fed to the engine. For a mower with such a motor, you need AI-92 and AI-95 gasoline. It is better not to use fuel with a lower octane number, because this will lead to unstable engine operation. In addition, do not use a lubricant designed for two-stroke models.
The oil that is poured into the motor may differ in the production method. According to this criterion, it happens:
- mineral. this type is obtained during the processing of petroleum products;
- synthetic. it is obtained by processing or synthesizing gas;
- semi-synthetic. this type has better characteristics due to the introduction of synthetic-based components into it.
Lawn mower oil refers to formulations intended for use in air-cooled engines that have a combustion chamber volume of 50-200 cubic centimeters. In addition, any two-stroke oil can differ from analogs in additives that give it certain additional characteristics. They are of the following types.
- Antiwear. The main task of the oil will be to reduce wear of parts during the operation of the device.
- Antioxidant. They do not allow oxidation to occur and make it possible to maintain the performance of the oil for a long time.
- Anti-corrosion. Their task is to prevent corrosion from forming on the engine parts.
- Friction modifiers. These additives can significantly reduce the coefficient of friction.
Two-stroke oil from different manufacturers may differ in the combination of additives used, which means that their properties will differ.
Recently, when purchasing oil for dilution with gasoline, users very often come across the fact that special letter abbreviations are applied to the cans. These designations are made within the framework of the API classification. Consider what types of oils exist in accordance with it.
- TA is used for air-cooled brushcutters with an engine displacement of no more than 50 cubic centimeters. It can be used not only for mowers, but also for mopeds, lawn mowers and other types of machinery. For the petrol grass trimmer, this is the optimal solution.
- TB is used to refuel a chainsaw, scooter, moped or motorcycle with an engine capacity of less than 200 cubic centimeters. Can also be used for refueling petrol trimmers.
- TC is suitable for thinning with gasoline and pouring into a snowmobile, motorcycle and other types of equipment.
- TD is intended for refueling boats, yachts and hoverboards.
But in addition to this classification, other letter designations of the FA-FD type are often found. It should be said that the API is an American standard that is used in Europe. But there is a discrepancy between European and American smoke emission regulations. For this reason, additional letter designations should also be taken into account.
- FA can be used in countries where minimum exhaust gas emissions are required by law. Barely noticeable smoke may be emitted when using oils with such markings.
- FB. can be used in countries where the restrictions on the emission of smoke and gases are much stricter. In this case, the smoke will practically not be emitted.
- FC. a transparent smoke appears here, which the human eye cannot notice.
- FD is a special category of oils for 2-stroke engines, they do not create smoke at all. They have increased chemical properties. Usually this oil is used for mixing with gasoline and subsequent refueling of boats and yachts.
In addition, oils come in two more categories:
In the first case, this will mean that it is necessary to carry out self-mixing, which does not require shaking, and in the second case, you will need to do it too.
