How Much Oil To 5 Liter Trimmer

A huge role in the performance and durability of the gas trimmer is played by oil, which protects the details of the cylinder-piston group from rapid wear.

In order for the lawn mower to please its owner with trouble-free operation, a competent approach to maintenance is necessary. Currently, it is customary to distinguish between two main types of engine by the number of working cycles:

The principle of operation of two- and four-stroke engines

  1. Two-stroke engines, where oil is added directly to the fuel tank;
  2. Four-stroke engines with separate oil reservoir. An exception in this category is the STIHL 4-MIX engine, which runs on an oil-gasoline mixture, but has 4 cycles of operation.

Nevertheless, most of the trimmers on our market are equipped with power units operating on a mixture pre-prepared filled into the fuel tank.

Types of motor oils and their purpose

The choice of oil for gas trimmer

Oil for the engine of a gasoline trimmer is a lubricant that serves to reduce wear between the friction components of the internal combustion engine.

The composition of the oil includes residual hydrocarbons and various additives that improve the properties of the final product. To ensure long-term and trouble-free operation of lawn mowers, experts recommend the use of oils that, in their physicochemical properties, correspond to this type of motor.

Today it is customary to distinguish three main types of oils by the method of their production:

  • Minerals created in the process of distillation of hydrocarbons;
  • Synthetic oils obtained through natural gas processing or synthesis;
  • Semi-synthetic, including 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 oil, which shows the difference in the composition of the lubricant.

The choice of oil for lawn mowers

For trimmer motors, it is necessary to select oils with the “2T” marking, 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, it is worth paying 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, a lot of costs.

Two-stroke lawn mowing oil

The main factor determining the quality of the oil for the trimmer is the alkaline number. It is this component that eliminates the oxidation of rubbing parts and slows down their destruction. During operation, the oil gradually loses its alkalinity and becomes oxidized. The optimum level of acidity (Ph) should not be less than 8-9 units.

The viscosity of the lawn mowing oil also has a major impact on the operation of a gasoline tool. This indicator determines the possibility of operating the trimmer at different temperatures. For example, summer brands of lubricants thicken even with a slight drop in temperature. Due to the use of lawn mowers exclusively in the spring-autumn period, oil with summer marking will be an excellent option.

The flash point for the trimmer oil should be more than 225C, otherwise the oil will quickly burn out, and the piston group will undergo intensive wear.

What to look for when choosing oil?

Modern two-stroke engines of the lawn mowing unit are fueled with a mixture of AI-92 gasoline and oil with the marking "2T". The use of fuels with a higher octane rating will contribute to an increase in the flash point and, as a consequence, the burnout of the lubricant.

Varieties of Stihl oils

Undoubtedly, the best oil for the trimmer is recommended by the manufacturer, however, the owner does not always have the opportunity to purchase exactly the “branded” lubricant. Experts recommend Shell Helix Ultra, based on Pureplus technology, which helps improve the basic properties of the lubricant.

For gasoline trimmers from the German manufacturer Stihl, it is necessary to use Stihl HP Ultra, Stihl HP, Stihl HP S oils. Vityaz products, which in their properties are most similar to the recommended material, can become a budget substitute.

How much oil to pour into the trimmer?

Depending on the number of strokes of the engine and the type of oil used, it is necessary to strictly observe the proportions when preparing the fuel mixture.

Proportions of gasoline and oil

So, when preparing fuel with mineral oil, the proportions can vary from 1:25 to 1:35. For high-speed engines with synthetic oil, a portion of the lubricant and gasoline can be 1:50 or 1:80. Fuel preparation consists in pouring a certain amount of oil into gasoline and subsequent mixing.

For long-term storage of a diluted mixture of PVC packaging is not suitable, since when interacting with plastic, the solution loses its properties. Do not allow long-term storage of cooked fuel (more than 2 weeks), which leads to the formation of an oil film and malfunctions of the fuel system.

Running outboard outboard motor.

Tips for use.

So, you just got a brand new outboard motor. As we understand, the outboard motor is a rather expensive technical product. The following article is intended to provide some general guidance on the care and maintenance of your new "child". I must say that these recommendations are suitable for outboard motors of any manufacturer. Remember that these are only recommendations and that this article is not intended to replace "Operating Instructions" and official "service manual".

It must be remembered that how you relate to your engine in the first 10 hours, so it will relate to you for the first 10 years. This means that if you intend to keep it in excellent condition for a long period of time, then it is better not to experience its maximum power in the first minutes of operation. The first step is to understand that modern production technologies make it possible to build today’s motors with extremely tight tolerances. This is what happens inside the engine. Piston rings abut in the cylinder with a lot of friction, and a lot of heat is associated with this. To avoid excessive friction, you must take two simple preventive measures.

Firstly, during break-in, as a rule, the first 20 hours or 40 liters of fuel are considered, additional lubrication must be provided. To do this, add additional oil to the fuel for a two-stroke engine. This means adding one liter of oil per 40-50 liters of gasoline, and not per 100 liters, as during the normal period of operation. During the break-in period, it is recommended to avoid the use of various detergents in gasoline. Oil, of course, should be used only high quality and proven. Just look at the photos of the pistons and rings after using bad oil to understand how important this is.

Another precaution is to limit and prevent sudden changes in engine speed. The general rule is to not exceed 85% of the maximum speed during the first 10 hours. Also, do not operate the boat at a constant speed for more than a couple of minutes.

After a preliminary break-in, it is necessary to service the gearbox, since the gears in the leg are run-in and this, as a rule, leads to some metal particles in the gear oil. Also, an additional check of the state of transmission oil (in the case of an emulsion) allows you to diagnose leakage of gearbox oil seals in time. As sudden damage to the seals is possible, for example, due to coiled fishing line or fishing net.

Water pump (pomp).

The impeller of the water pump is the most neglected unit in the routine maintenance of the outboard motor. Just remember to flush the motor every 200 hours if operating in fresh, clean water or every 100 hours. In salty / brackish water or high silt water.

One more tip. If you decide to do it yourself, make sure that your engine is left without water after flushing.

"ALTAIR" (Jamika) Gearbox, propeller and output shaft.

Before the onset of frost, each season it is necessary to change the oil in the outboard motor gearbox (foot). This is also a good reason to check the propeller shaft for wire or fishing line that could damage the output shaft seals. Lubricate the shaft before replacing the propeller (especially under marine conditions). If any water is found in the oil of your gearbox or a liquid similar to coffee with cream escapes (oil emulsion), contact your nearest dealer or mechanic and have the motor checked. Rust will damage gears and other gear parts over time. If it comes to winter. Water in the gearbox will freeze, damage the parts, which will lead to excessive wear of the gearbox.

Damage to the propeller? – it is better to replace the screw. Just imagine that one blade is shorter or damaged, the motor runs at full power. A little time will pass and the unbalanced shaft and gearbox will be in a deplorable state. Bearings, oil seals and other failed parts will cause serious, if not catastrophic, consequences for your engine. One more tip. When changing the gearbox oil, always watch out for the small washers of the filler and drain screws. If you lose the puck. Get water leaking into the gearbox with all the consequences.

If you have not been lucky enough to live in a climate that allows you to operate the boat 12 months a year, then you will inevitably encounter the storage and preservation of the outboard motor. Nothing causes more problems with mechanical devices than improper storage. You will even like to do the necessary routine maintenance before storing the motor in the winter, especially since it is very simple. It is recommended to add a fuel stabilizer to gasoline. This allows you to stabilize gasoline and the fuel system of the engine. Gasoline, which has been in the fuel system for more than a month, can decompose into tar and varnish, will clog the system. When storing the engine in freezing weather, be sure to remove all water from the engine. Do not store the motor in an upright position. If water remains in the exhaust system, it may freeze and break the lower unit.

So, above are some tips and tricks about the durability of outboard motors. It should be added that this is more true for engines that are used almost exclusively in fresh water. Salty sea water. Incredibly destructive environment. So, if you really need to use the boat in salt water, then to all of the above you need to clean and rinse the motor with fresh water after each walk!

"ALTAIR" (Jamika) Decarbonization. Two stroke engines.

The two main features of a two-stroke motor head are heat and carbon. Heat causes excessive and premature wear, and soot causes a number of unpleasant small problems. These include (but are not limited to) bedding and piston detonation. If you take regular preventive measures to combat these two “enemies” of your engine, you can easily double its service life. A modern outboard two-stroke outboard motor can serve for a very long time, but it cannot do without proper maintenance.

The engine may not work well, detonation may occur in the cylinders due to carbon deposits in the combustion chamber. There are two ways to avoid this. You can use fuel additives. This is the most expensive way, but when all the pros and cons are weighed, it will still be cheaper than the cost of repairs.

Another way is extreme. This method is not recommended if you are not confident in your abilities. Make sure you have enough distilled water. Then remove the hood and dismantle the air filter housing. Start the engine. Raise the engine speed to around 1200-1400 rpm. Take a syringe with distilled water. Gently inject water in very small portions into the inlet. Engine speed will fall, but do not let the engine stall. Move quickly from one inlet to another until you are using enough water. Water vapor inside the cylinders will flush out all carbon deposits under pressure. The propeller will spray all the muck that will fly from the exhaust, be careful. After this procedure, it is necessary to drive on the engine in the normal mode on a boat with the water damper wide open. Once again, it must be emphasized that this method is not recommended due to its complexity and ambiguity.

So, you learned not only about the running-in of the outboard motor, but also about other, equally important points in the operation of outboard engines.
We hope these tips add many years of trouble-free operation to your outboard motor!
