What Does Trimmer Oil Look Like
Trimmer, or lawn mowing. A tool that can not be done in the household. At the same time, its reliability, efficiency and long service life depend on many factors. For example, the quality of fuel. This means that you need to choose the right oil for the trimmer, observe the proportions when adding to gasoline and the rules for refueling the device.
Which oil to choose
For the effective operation of the trimmer, it is necessary to select oil for two-stroke engines. This is due to the lack of an oil sump in such a device. The following classification is distinguished depending on the chemical composition of the oil:
- Mineral. Based on petroleum distillate, suitable for low-power equipment and with an air type of cooling, but requires frequent replacement and can only be used in good weather in the warm season;
- Semi-synthetic. Suitable for garden equipment with air and liquid type of cooling;
- Synthetic. 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 feature of complete combustion. For the trimmer, it is recommended to use a lubricant that is suitable for devices with an air cooling system. Most often on the package it is indicated that the oil is intended for gardening equipment and is marked TA, TV or TS. Over, the last of them is most preferable.
If the consumption of engine oil during the summer season is planned to be large due to the presence in the garden arsenal of a chainsaw, brush cutter, lawn mower, it is advisable to buy 5 liters of oil at a better price. If it is necessary only to mix with gasoline and fill a single tool, then 1 liter will be enough.
Often, manufacturers of lawn mowers produce the right oil, so you can make your choice easier if you select the appropriate brand fluid.
What kind of gasoline to fill
Gasoline for the trimmer must be selected unleaded with a stroke number of 92 or 95. As practice shows, AI-80 gasoline can lead to damage to the device, which is a dubious saving.
The fuel must be fresh, that is, after purchase it can be stored for no more than 60 days.
Other factors affect the quality of the fuel, for example, the use of a special lubricant for lawn mowing and diluting it in a separate container. It is also recommended to use special canisters designed to store gasoline.
How to dilute gasoline with trimmer oil
It is necessary to breed gasoline for the trimmer in the correct proportion. An insufficient amount of oil can lead to poor lubrication of the lawn mowing elements, which contributes to rapid wear. In the event that the oil is more than expected, soot forms on the pistons and spark plugs. Carbon deposits on moving parts of the engine interfere with normal operation and lead to a speedy engine breakdown.
What proportion is required for a particular trimmer model can be found in the attached instructions. Most often, for 2-stroke gasoline engines of lawn mowers, the fuel mixture is used in a ratio of 50: 1, where 50 is part of the gasoline, 1 is part of the oil. That is, 20 ml of oil should be added to 1 liter of gasoline. The table will help you choose the right ratio.
To measure proportions correctly, use measuring tanks with a milliliter scale. For these purposes, a special canister with a double neck is perfect, it is designed for mixing and storage of oil gasoline. For example, oil can be filled with a medical syringe without a needle. Before mixing liquids, make sure that the tank for the finished fuel mixture is free of water, dust and particles of dirt.
Diluting gasoline with lubricant directly in the fuel tank is unacceptable; moreover, the proportion of oil and gasoline must be strictly observed. If you ignore this rule, then the operation of the trimmer motor may be unstable, because of 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 has the ability to dissolve plastic, which means that part 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 two-stroke engines with an air cooling system;
- Canister, better metal;
- Mixing tank, also better metal;
In addition to protective equipment, do not forget about the fire safety rules, because gasoline and engine oil are highly flammable:
- It is better to carry out work on the street 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.
A mixture of gasoline and oil should be made as follows:
- Pour 1 liter of gasoline into the container, add half the right portion of oil. Mix thoroughly, do this extremely carefully away from sources of open flame.
- Add the remaining oil to the trimmer gasoline and mix thoroughly again. Now the fuel can be poured into the trimmer’s fuel tank.
The mixture can be stored for no more than three months, so it is better to dilute gas in such quantity that it is enough for several uses.
How and how much to refuel
Refilling the trimmer fuel tank is easy. To do this, place the tank so that the lid is placed on top. The amount of fuel depends on the trimmer model. This information is indicated in the instructions, there is also a mark on the tank directly.
This can cause the fuel to spill over into the inlet pipe and fuel filter, which can cause engine damage or ignition of the fuel.
When refueling the trimmer, the following safety precautions must be observed:
- Try to fill the liquid so that it does not spill, you can use a watering can for this;
- If the gasoline spills, then immediately wipe it off;
- Trimmer start should be started after the fuel tank is removed in a safe and secure place, preferably at a distance of more than 10 meters;
- With a long break between operations, drain the remaining fuel.
The correct proportion and adherence to mixing and dressing technology will help extend the life of the trimmer. In this case, it is recommended to choose only a quality product of the corresponding brand.
Specifications for the trimmer contain links to recommended fuel and lubricants. At the same time, 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 particular manufacturer. For convincing reasons, it is indicated that only when these recommendations are followed, the company extends the warranty. What is it: a marketing move or oils from other manufacturers do not meet the requirements? The answer is in this article.
Why mix trimmer oil with gasoline
The two-stroke engine has a simple and, at the same time, extremely efficient design:
- The piston makes a working stroke every second stroke;
- Cylinder lubrication is made 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 domestic and professional equipment:
- Various tilleries.
Due to the design features, it was possible to achieve the desired fuel consumption only on small engines with power in the range of 15. 20 hp. This indicator looks especially good in the range of 1. 5 hp. Here, the fully low weight and dimensions of the engine correspond to gas mileage.
With increasing size, the area of the inlet and outlet channels increases. The process of gas removal and fuel supply is deteriorating sharply. In this regard, the transition to a more efficient combustion system of the gasoline mixture, which would require the presence of forced engine maintenance systems, was required. Four-stroke models thereby seized the palm among the power units of high power. Their combination into multi-cylinder structures allowed the creation of special systems related to the formation of the composition of the fuel mixture, lubrication and other things, which favorably affected the consumption of gasoline.
The lubrication of the rubbing elements of the piston and cylinder of a two-stroke engine occurs with oil, which is in a certain proportion in the composition of the fuel. Gasoline burns, 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 the case of an excess, under the influence of high temperatures, a thermally modified product is deposited in the annular grooves. Compression drops, and with it the power.
How to mix oil with gasoline
Engine oil is used to supplement trimmer gasoline. Mixing is carried out in a certain proportion. Manufacturers have a different volume ratio: from 1 to 50 to 1 to 20. In the technical specifications there is a link to this. Care should be taken with a small proportion of the oils. A small inaccuracy leads to oil starvation of the engine, reduces its resource.
There are products in which a proportion of 1 to 20-40 is indicated. It is better to refuse the use of such a lubricant. A wide range of mixtures indicates low product qualities. The occurrence of piston rings, with the constant use of such grades, is almost guaranteed.
Motor oils, type M-8, are added in a proportion of 1-20. In high-speed engines, their use is undesirable. The cycle between the supply of the mixture is so small that it will cause an excess of lubricant in the cylinder. Trimmers have low revolutions, therefore they allow the use of low-grade grease. Due to the initially low resource, you can not worry about the coking rings. First, there will be a complete wear of the equipment.
The principle is not the use of recommended oil or from other manufacturers. The main thing is to dilute gasoline with trimmer oil in accordance with the proportions in accordance with the characteristics of the product. The refusal of service workshops to guarantee only on the basis of using a different brand of grease, but with acceptable parameters, is illegal.
