How to choose the right proportion?
The lawnmower is filled with A-92 gasoline. There are other factory instructions that require second-octane gasoline. For example, A-95. The difference in cost is minimal.
Oil selection does not take liberties. For two-stroke engines, the API sets a specific order:
- For tillers, lawn mowers, air cooled mopeds. I class;
- Engines with a cylinder volume of 200 cm³. TB class oil;
- Recommends the use of TC class oils for all-terrain vehicles and motorcycles;
- Yacht engines, hydro scooters, motor boats use TD brand lubricant.
From the above list, engine lubricating fluid of the last two positions is not recommended for use with trimmer power units. Letter designations indicate from which petroleum products the lubricating fluid is made.
Standard proportions
First of all, it is necessary to take into account the information that the manufacturer recommends, since in the event of a failure of the lawn mowers, you can present your claims to him, and not to a third-party source. If there is no instruction in the passport, and even more so if there is no passport, we recommend that you look for another trimmer model in a more reliable seller.
For all other cases, when you have a lawn mower model in your hands and there is no way to find out its technical features, there are standard proportions of the Most probable fuel mixture components for a two-stroke engine. Basically, for THESE units, AI-92 gasoline and a special synthetic oil are used, which contains a solvent for better mixing with fuel. This oil evaporates slowly and has the ability to completely burn out in the cylinder, Do not leave carbon deposits.
The standard ratio of synthetic oil to gasoline is 1: 50. This means that 5 liters of gasoline need 100 ml of oil, and in accordance with this, oil consumption per 1 liter of gasoline is 20 ml. Knowing the amount of oil required to dilute 1 liter of fuel, you can easily calculate any rates when preparing fuel for the trimmer. When using mineral oils, a ratio of 1: 40 is most often the standard. Therefore, 1 liter of fuel will require 25 ml of such oil, and for a 5-liter canister. 125 ml.
When working with lawn mowers, a person with little experience in operating such equipment will not be difficult to determine and adjust the actual amount of oil required for a particular model. You should only pay attention to Exhaust gases (their color, odor toxicity), cycle stability, engine heating and developed power. details about the consequences of incorrect mixing proportions of gasoline and oil can be expected in another section of the article. There are variants of lawn mowers running on AI-95 gasoline. This should also be considered.
How to mix gasoline with trimmer oil. Trimmer Fuel Mix: Practical Tips
A lawn mower is the same equipment necessary for a suburban or garden plot, like a tiller or a chain saw. An unpretentious tool in operation, Demanding exclusively on the quality of the fuel mixture and its own purity. And if there is usually no misunderstanding about keeping lawn mowers clean, some users periodically have questions about the composition of the fuel. How do you dilute gasoline with trimmer oil to keep it working as efficiently as possible? What are the consequences of an excess or, conversely, insufficient amount of oil in gasoline? The answers to these simple questions lie on the surface: you need to understand what role the lubricant plays in the operation of a two-stroke engine.
How to choose for lawn mowers?
For two-stroke engines, lawn mowers 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 which gasoline the trimmer should work, you can choose it 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 and or another model of the unit “likes” 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 in the equipment manufacturer. And already according to the standard proportions for this manufacturer, select the proportion for a specific model, taking into account the type of oil.
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. In the choice of standard proportions for lawn mowers of European and American manufacturers in connection with the type of oil, we have already told you earlier. According to the class of oils for household trimmers, you need to use TB oil according to the API classification. For more powerful. class TS.
For the ratio of gasoline to oil required for lawn mowers, see the following.
How to properly prepare the fuel mixture for the trimmer?
We will tell you how to dilute gasoline with trimmer oil. First, you should tackle organizational issues:
- Selection of containers for storing the components of the fuel mixture. Buy metal cans for gasoline. Factory packaging is sufficient for lubricants.
- Do 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 be added to gasoline for dilution.
We draw the attention of trimmer owners to one detail. You should not buy lubricants for future use. Buy volume that will last for the coming season.
Why buy trimmers?
Comparing with similar mechanisms, lawn mowers are preferred when choosing according to the following functional indicators:
- Mobility and low weight of the unit, allowing it to be transported over distances, used in hard-to-reach places for mowing.
- Versatility. The lawn mower is equipped with a unit for changing working elements directly during the operation of the unit.
- Constructive simplicity, allowing long-term use of the braid without frequent adjustments.
Gasoline to lawn mower oil ratio
Lawn mows are a fairly common technique for combating weeds in summer cottages, in road gardens and housing and communal services. These devices have two more names. trimmer and lawn mower. These units differ in their engines. The more expensive ones have four-stroke engines, all the others have two-stroke engines. Of course, the latter are the most popular among the population, since they are simpler in design, lighter in weight, and much cheaper than their four-stroke competitors. However, two-stroke models are inconvenient in that the fuel mixture for them must be prepared manually, maintaining a strict dosage between gasoline and oil. In four-stroke analogs, the mixing of THESE components occurs automatically, you only need to fill the gas tank and oil tank with the corresponding substances. Let’s consider the issue of the correct refueling of two-stroke lawn mowers, since it depends on how effective and long the operation of such a unit will be.
Two-stroke and four-stroke
Internal combustion engines used in trim tabs come in two-stroke and four-stroke. By design, two-stroke engines are simple. But they require a high-quality fuel mixture.
A four-stroke engine does not require the correct proportion of oil and gasoline. Formation of the desired mixture is automatic. The components of the combustible mixture are stored in different containers. The fuel is expensive, but the costs are covered by the silent operation of the unit, the environmental friendliness of the exhaust gases.
