How to Mix Gasoline with Grass Trimmer Oil
Refueling a brushcutter with a four-stroke engine
Four-stroke engines are used in professional brushcutters. They have great power and can work for a long time without interruption and refueling. They also use gasoline and oil as fuel, but they are poured into different tanks. This means that the oil does not participate in the combustion process, therefore the exhaust gases are not so toxic.
On a note! Along with better environmental performance and the ability to heat less, the four-stroke brushcutter engines are also more economical. They consume much less fuel. savings up to 50% for gasoline and up to 80% for oil.
Features of operation of Huter GGT-1500TX
The operation of the grass trimmer is not very difficult, and after carefully studying the instructions and assembling the resulting product, you can start preparing the grass trimmer for work. Let’s briefly consider how to properly assemble the Huter GGT-1500TX and prepare it for use. At the initial stage, we install the control handles using a special key included in the delivery set. When connecting elements, always check that everything is done securely. Now you can move on to the next step: connecting the boom to the motor. Installation is carried out using a standard set of bolts. Once the boom is connected to the motor, the shroud and cutting elements can be installed. Read more about the step-by-step assembly of the grass trimmer in the Owner’s Manual.
The assembled grass trimmer can now be prepared for the upcoming work on the site. Preparation for operation begins with the preparation of the fuel mixture. At this stage, follow all the manufacturer’s recommendations on the brands and quality of the fuel mixture components, and also accurately follow the method of preparing the fuel mixture, which, in fact, is not very difficult.
Since the Huter GGT-1500TX is equipped with an air-cooled two-stroke engine, a high quality oil, specially produced for the mentioned type of engines, is needed to prepare the fuel mixture. According to the classification, this oil is API TV / API ТС, JASO FB / JASO FC. It is recommended to fill in oil which is produced by Huter itself under the Huter 2T label. The second component of the mixture must be high quality gasoline, the octane number of which is at least 92. It is strictly forbidden to use oils in the fuel mixture that are produced for water-cooled engines. The fuel mixture is prepared in a ratio of 1:40 (1. oil, 40. gasoline) or according to the recommendations of the oil manufacturer.
For the process of preparing the mixture, use a special measuring container. The amount of the mixture should be calculated only for one cycle, so that after the completion of the work, there are no residues of the fuel mixture in the tank (you cannot leave it in the tank until the next cycle of work). Also, never use the tank itself for preparation of the mixture, and also do not carry out operations with the components of the fuel mixture near a fire and do not smoke while preparing the fuel.
After the correctly formulated fuel mixture is poured into the tank, you can proceed to the direct preparation of the grass trimmer for work. To do this, the user must first put on a knapsack belt and fasten it securely, but conveniently for himself. After that, using a special carabiner, the grass trimmer is attached to the belt and adjusted if necessary. For details on preparing the grass trimmer for use, see the Owner’s Manual.
The power of the Huter GGT-1500TX is 1.5 kW, which, along with the features of the cutting tool (line / knife), classifies it as a semi-professional class of such devices. Therefore, the model can be used not only in dachas and country farms, but also in small farms. The GGT-1500TX is great for mowing grass and tidying up areas with small bushes. The grass trimmer weighs 6.78 kg, making it relatively easy to transport, even in a regular passenger car.
Features of refueling brushcutters
Depending on the design of the engine, brushcutters are divided into two-stroke and four-stroke. In the first case, the piston in an internal combustion engine makes 2 strokes in one working cycle, and in the second case, 4 strokes. Differences in the principle of operation of the engine also cause different approaches to refueling the grass trimmer.
Work conveniently and safely
Of course, the operator must follow all safety recommendations and requirements, follow the rules for using the grass trimmer. However, in addition to this, the manufacturer has taken a number of measures in relation to the design of the device in order to increase the level of safety when working with the brushcutter. These include, in particular, the presence of:
- a protective cover to prevent bouncing stones and debris from falling onto the user,
- throttle blocking trigger to prevent operator accidentally pulling the trigger and starting rotation
- cutting tool when the engine is running,
- anti-vibration system to prevent harmful effects of the vibrating elements of the grass trimmer on the hands and other parts of the operator’s body.

How to dilute gasoline with grass trimmer oil?
The grass trimmer specification contains links to recommended fuels and lubricants. In this case, the octane number of the brand of gasoline is indicated specific, but in the part of oils there is a lengthy explanation about the need to use a product of a certain manufacturer. For the sake of persuasiveness, it is indicated that only if these recommendations are followed, the company extends the warranty. What is it: a marketing ploy or oils from other manufacturers do not meet the requirements? The answer is in this article.
Why Mix Grass Trimmer Oil with Gasoline
The two-stroke engine has a simple yet extremely efficient design:
- the piston makes a working stroke every second stroke;
- the cylinder is lubricated with oil dissolved in gasoline;
- 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 been successfully adapted in household and professional equipment:
- grass trimmers;
- various motoblocks.
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 figure looks especially good in the range of 1. 5 hp. Here, in full measure, the low weight and dimensions of the engine correspond to the consumption of gasoline.
As the size increases, the area of the inlet and outlet channels increases. The process of gas removal and fuel supply deteriorates sharply. In this regard, a transition to a more efficient gasoline mixture combustion system was required, which would provide for the presence of forced engine maintenance systems. Four-stroke models have thus intercepted the palm among high-power powertrains. Combining them into multi-cylinder designs allowed the creation of special systems associated with the formation of the composition of the fuel mixture, lubrication and other things, which had a beneficial effect on gasoline consumption.
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 fuel composition. Gasoline burns out, and oil settles on the surface of the cylinder, reducing the friction of the rubbing parts. Lack of lubrication leads to cylinder damage, up to and including seizure. In case of excess, under the influence of 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 to the grass trimmer gasoline. Mixing is done in a certain proportion. Manufacturers have a different volume ratio: from 1 to 50 to 1 to 20. There is a reference to this in the technical specifications. You should be careful with small proportions of oils. A small inaccuracy leads to oil starvation of the engine, reduces its resource.
There are products in which the proportion of 1 to 20-40 is indicated. It is better to refuse to use such a lubricant. The wide range of the mixture indicates the low quality of the product. The occurrence of piston rings, with constant use of such grades, is practically guaranteed.
Motor oils, type M-8, are added in a ratio of 1-20. In high-speed engines, their use is undesirable. The cycle between supplying the mixture is so small that it will cause an overabundance of lubricant in the cylinder. Grass trimmers have low RPM so they can be used with low grade lubricant. Due to the initially low resource, you do not have to worry about the coking of the rings. Before the equipment is completely worn out.
It is not essential to use the recommended oil or from other manufacturers. The main thing is to dilute the gasoline with grass trimmer oil in the correct proportions in accordance with the characteristics of the product. Denial of warranty by service workshops only on the basis of the use of a different brand of grease, but with acceptable parameters, is illegal.
How to properly prepare the grass trimmer fuel mixture?
Here’s how to dilute gasoline with grass trimmer oil. You should first tackle organizational issues:
- Selection of containers for storing the components of the fuel mixture. Buy metal cans for gasoline. Factory packaging is sufficient for lubricating fluids.
- You should not prepare a large volume of a mixture that is flammable in engines, since its structure will be disturbed. Separation into fractions will begin: the heavy will sink to the bottom, and the light will form the top layer.
- Prepare a medical syringe for precise dosage of lubricant to add for dilution into gasoline.
We would like to draw the attention of the owners of the grass trimmer to one detail. You should not buy lubricants for future use. Buy the volume that is enough for the upcoming season.
Algorithm of actions
Fuel quality increases with proper mixing of the mixture components. The question arises before the mower, how to breed, in what sequence. When mixing the components, pay attention to whether the containers are cleanly washed. A tiny slurry can stall the fuel supply to the carburetor. The fuel tank should be filled from a special container with a filter device.
The procedure is as follows. Half of the available gasoline is mixed with the volume of the specified amount of lubricant. This is followed by the mixing process.
When the components acquire a homogeneous consistency, 50% of the remaining fuel is poured into the partially diluted gasoline. This is how it is recommended to dilute the grass trimmer fuel.
The prepared combustible mixture for the grass trimmer enters the combustion chamber of the cylinder in the form of a whitish mist. The oil integrated into gasoline lubricates the crankshaft and cylinder walls. Underfilling with oil in the fuel is fraught with premature wear of parts and assemblies of the grass trimmer. Exceeding the norm leads to soot settling on the working parts, which is also fraught with premature technical wear of the brushcutter.

A gasoline mower will serve the owner for a long time, provided that they will not pour any gasoline into the fuel tank, but high-quality fuel.
Gasoline for grass trimmer
Gasoline grass trimmers are ideal for site maintenance thanks to their portability. These models of lawn mowers require periodic fuel changes. The choice of gasoline must be approached competently. It is not worth saving much on the purchase.
How to choose for a lawn mower?
For two-stroke engines, brushcutters use AI-92 or AI-95 gasoline. Most often. the first of the named. There is always information about this in the technical data sheet of the product. If, for some reason, it is not known exactly on what gasoline the grass trimmer should work, you can pick it up by testing both brands of gasoline in action. Global changes in the engine will not happen from this, and it is quite possible to determine what kind of gasoline this or that model of the unit “loves” more, according to some factors. This will be shown by the developed power, and throttle response, and engine heating, as well as its stable operation at all speeds.

But it is much more difficult to determine the proportions of oil to a certain volume of gasoline. In this case, you need to know at least something about the manufacturer of the equipment. And already according to the standard proportions for this manufacturer, select the proportion for a specific model, taking into account the type of oil.
You can start selection even by country of origin.
For example, for Chinese low-power trimmers, two ratios are mainly used. 1: 25 or 1: 32. The first is for mineral oils, and the second is for synthetic oils. We have already talked about the choice of standard proportions for petrol cutters of European and American manufacturers in connection with the type of oil. According to the class of oils for household trimmers, you need to use TV oil according to the API classification. For more powerful. class TS.
For information on the ratio of gasoline and oil needed for a lawn mower, see the next video.
Fuel for a two-stroke engine: theoretical part
The operation of a two-stroke power plant differs from the operation of four-stroke engines in that the lubrication of the rubbing surfaces in the cylinder-piston group, the crankshaft, in the bearing supports is carried out not from the crankcase, but due to the oil previously dissolved in gasoline. For two-stroke trimmer engines, the general rules for preparing a combustible mixture are preserved: gasoline must be diluted with a certain amount of oil intended for this purpose.
Oil for lawn mowers in its properties does not fundamentally differ from lubricants intended for use in other garden equipment with a gasoline two-stroke engine.
According to the API (American Petroleum Institute) classification, several types of such oils are accepted:
- class TA is used in air-cooled two-stroke internal combustion engines of mopeds, lawn mowers and other related units with a volume of up to 50 cm3; up to 200 cm 3;
- class TB. for mopeds, gasoline saws, scooters and low-power motorcycles with a volume of 50 to 200 cm 3;
- TC class is used when operating motorcycles, snowmobiles and other land vehicles;
- class TD defines belonging to special certification for outboard motors, hydro scooters, two-stroke internal combustion engines of yachts and boats.

It must be remembered that classes TA and TB are not identical in composition and properties, therefore they are not interchangeable.
In addition to API, there is the JASO system, according to which oil for 2-stroke engines is classified in Japan. In this system, the following division by quality level is accepted:
- FA class is intended for use in countries where the legal requirements for the emission of smoke from motors are minimal;
- class FB. for two-stroke engines of units operated in countries with high legal requirements for the level of smoke generation;
- FC class is represented by smokeless motor oils intended for two-stroke engines;
- class FD. smokeless oils for two-stroke internal combustion engines with improved characteristics, intended mainly for outboard motors and stationary internal combustion engines of boats and yachts.
When choosing oil for a lawn mower, it should be borne in mind that lubricants from Russian manufacturers intended for use in two-stroke engines are often marked with the 2T index. There are also markings “self mix” and “pre mix”. The first means that the oil, when added to the fuel, mixes itself, without additional stirring. The second should be diluted by forced mixing. shaking or in another way.
What two-stroke engines dislike?
When preparing the working mixture manually, it should be remembered that two-stroke engines do not reach their design working power if the proportions of the fuel mixture are violated. The above condition forces the owner of the unit to comply with the proportions. As practice shows, the use of brushcutters with an underfilled lubricant product. there is an oil starvation of the engine, which does not allow the unit to be brought to the rated power.
Excess lubricant prevents the engine from developing the required power. When preparing the working mixture, a reasonable question arises, how much oil needs to be mixed in gasoline. Helps to define the exact standard. It is recommended that gasoline is poured into the grass trimmer according to the following mathematical calculation. If the fuel tank holds 5 liters, 1 liter of gasoline is divided by 50. That is, 100 ml of lubricating consistency is poured into the gasoline for the grass trimmer mower per 5 liters. The owner of the brushcutter gets the ideal fuel in terms of structural composition.
