Oils for lawn mowers and trimmers: which oil to choose and how to replace the oil

How to Change Oil in a Lawn Mower

Over the past years, there has been a slight increase in the construction of suburban housing. Residents of megacities are actively striving to change the asphalt paths of cities to the even beautiful lawn of their suburban area. But to create a beautiful smooth lawn you have to work a little. Prepare the soil, level it, plant seeds of lawn grass, water them. Now it remains to wait when it rises, and green lawn grass rush out. But the process did not end there, the next stage will stretch for the entire summer season, this is lawn care. To keep the lawn in shape, you need to mow it.

Even if your site does not have such a prepared lawn, and the grass just grows, you won’t be able to get rid of periodic mowing. After all, if you do not do this, the site can quickly turn into impassable thickets. Therefore, almost every owner of a summer cottage cannot do without modern technology, which greatly facilitates the maintenance and care of the land itself and the surrounding area.

Mowing the grass or mowing the lawn in the area without lawn mowing or lawn mowing would take away the whole day, hardly anyone would happily donate a day off to such an event. On the other hand, the availability of small-scale mechanization significantly reduces the time spent on mowing, and in some cases even brings pleasure both from the process itself and from its result.

Grass mowing devices with an internal combustion engine are now presented in a huge number of any configurations. This technique is equipped with 2 or 4-stroke engines, depending on the purpose. And the key to a long uninterrupted service is just the timely maintenance and use of high-quality lubricants.

The role and function of oil in the engine of a lawn mower and trimmer

We note immediately that engines mounted on braids, trimmers and lawn mowers have significant differences from automobile and motorcycle. The engine design, in order to reduce the cost of production and ease of maintenance, is devoid of an oil pump, which increases the requirements for engine oil, in particular its viscosity.

The distribution of engine oil in the engine of the lawn mower occurs using a crankshaft. Oil is scooped out of the crankcase, roughly speaking, with “special spoons” and sprayed onto the parts. Now imagine the speed of such "spoons". it turns out a great mixer! Therefore, one of the most important components of oil for lawn mowers is the availability of high-quality "anti-foam" additives. Cheap varieties of oils for gardening equipment, as well as oils for cars, have much less such additives in their composition. Therefore, it is important to use only high-quality oils intended for gardening equipment.

Such a lubrication system implies that the viscosity of the oil must support the ability to stay on the parts and at the same time not impede the movement of engine parts.

In addition to the maximum lubricating properties, the oils used in the technique for "mowing" should perform a number of useful functions:

· Remove heat from hot engine parts

· Resist engine wear

· Minimize the formation of deposits, deposits, varnish

· Meet current environmental requirements

· Contribute to exhaust emissions

· Work with minimal smoke

· Meet the requirements of the manufacturer of the equipment

Even with the condition that the design of the engine of the lawn mower is quite simple, the set of requirements and properties of motor oil is impressive. Therefore, the choice of lubricant must be approached responsibly.

In winter, no one uses lawn mowers, the equipment is spared from "cold start" at low temperatures, which would certainly affect the engine resource. But in the summer period, you need to make sure that the equipment does not overheat, since they have air cooling of the engine and therefore the temperature of their engines is higher than that of liquid-cooled engines.

Differences between 2-stroke oil (2T) for lawnmowers and trimmers from four-stroke (4T)

Despite the general working tasks of oils in a 2- and 4-stroke engine, the oils themselves are used different. The difference in oils is determined by the difference in the operation of these engines. On 2-stroke engines, lubrication occurs with oil pre-mixed with fuel, as a result, the oil burns with the fuel. There are variations of 2-stroke engines, where oil and fuel are supplied to the combustion chamber from separate containers, but the result is not changed and the oil mixed with the fuel burns in the chamber along with gasoline. In 4-stroke engines, in contrast, the task of oil is not to get into the combustion chamber.

Trimmers and lawn mowers belong to hand tools, and imply a compact design for the convenience of working with them. The design of 2-stroke trimmers and lawn mowers in most cases is equipped with one tank for pouring the finished fuel-oil mixture. Less commonly, when there are options with separate tanks for oil and gasoline.

From these engine operating conditions, the main differences in oil requirements also follow. Oils for 2-stroke engines should be burned as completely as possible and in the process of burning to minimize traces of soot in the form of ash and soot formation. Oils for 4-stroke engines are aimed at stable lubrication, for a long time, while maintaining their properties.

Briefly about the API and the rest

The main factors characterizing modern engine oils “at the global level” are considered to be efficient fuel saving, long intervals between replacements and low level of harmful substances emission (low smoke and toxicity of exhaust gases). These are general requirements for oils; the API defines more specific ones. The higher the class of motor oil, the more it meets the main factors, i.e. it has a higher level of quality and, naturally, it is more expensive. Modern oils are considered oils that comply with API SM and API SN. If the oil has a double designation, for example API SL / CF, then this is a universal oil, suitable for both gasoline and diesel engines.

Oils for two-stroke engines (ground equipment) have their own classification system. They are usually divided into groups depending on the degree of work stress (thermal and dynamic loads are taken into account). TA, TV, TS, TD. The highest demands are placed on oils of category AP TD. Surprisingly, it is a fact: the chainsaw engine is not inferior to motorcycle chainsaws in terms of work intensity, and the oils for them must correspond to a category of at least TC.

Japan, due to the widespread use of 2-stroke engines, has developed its own engine oil classification system, JASO. Currently, the ISO international organization classifies oils for such engines in three categories: ISO-L-EGB, EGC, EGD. The most stringent requirements are placed on the ISO-L-EGD category, respectively, the farther from the beginning of the alphabet the last letter of this marking, the better the oil.

How often do I need to change the oil in a 4-stroke lawn mower

Gardening equipment with a 4-stroke engine is still not a car, there is no odometer on it, so you need to focus on engine hours. The specific value of the service interval is indicated in the instruction manual. The average value is conditionally taken 50-60 hours. For example, if we have a small plot of land that requires a periodic approach to it with a mower, then so many working hours are unlikely to run over the entire season. In this case, the oil will be replaced at the time of preservation of the device for the autumn-winter period of time.

For the period of time autumn-winter, do not neglect such a procedure as conservation. The conservation process is not complicated and includes the processing of special compounds of electrical compounds and a combustion chamber. The implementation of this procedure will help to preserve the equipment even in adverse storage conditions, for example, in rooms with high humidity. About technology conservation technology can be found at the link.

Differences between oils for lawn mowers from automobile and motorcycle oils

Any internal combustion engine has certain operating features. Also, engines have a difference in the design of the assembly of units and parts, as well as a difference in the materials from which the same units or parts are made. To date, the situation on the market is such that almost every engine of modern technology needs to use an “individual” lubricant. Engines for gardening are no exception. As we have already mentioned, the motors of trimmers and lawn mowers have design differences from engines of large cars and motor vehicles. Therefore, the required oil for such a technique has differences in additive packages. A more important requirement for oils for gardening equipment is environmental friendliness and biodegradability.

Which lawn mower oil to choose?

As we have already mentioned, the operation of equipment without repair depends not only on timely service. It is important to choose the right lubricant. Choosing cheap low-quality oil, you can significantly reduce the work of garden equipment.

Perhaps someone paid attention to the number of restrictions on the use of lubricants for earthwork and green planting in Europe. For example, in Germany the most stringent requirements. Without special permission from the environmental committee and non-compliance with environmental standards, lubricants cannot be used by utilities to work in forest plantations and city parks. By the way, the German company Liqui Moly has such permission.

Liqui Moly, one of the leading manufacturers of lubricants, including for garden equipment, is guided by high demands on its products. Oils for trimmers and lawn mowers in the Liqui Moly assortment are designed for the technical conditions of modern technology. Additive packages included in the oils for trimmers and lawn mowers reduce wear, maintain engine cleanliness and significantly reduce carbon formation, which increases engine life. But besides this, Liqui Moly oils are made with high environmental standards, as they are made on a plant basis.

How to choose lawn mower oil?

The choice of engine oil for a lawn mower will initially depend on the type of engine. Suitable oils for 2-stroke and 4-stroke engines are divided by type of base oil:

The lubricating properties of the product, the ability to remain in a liquid state at lower temperatures, while not increasing viscosity, will depend on the base.
It is important to choose products that meet environmental standards. We recommend choosing Liqui Moly oils from a specialized garden program. Oils of the garden program meet not only the technical requirements of modern garden equipment, and correspond to European environmental standards.

How to change the oil in a lawn mower with a 4-stroke engine

The maintenance process for a lawn mower with a 4-stroke engine is not complicated.

Changing engine oil is carried out in several steps as follows:

· The mower starts and runs for approximately 10-15 minutes. This allows the engine oil to warm up, which, when draining oil from the engine, will contribute to a more complete drainage of mining.

· The engine stops, the drain plug on the crankcase is loosened.

· To drain the used oil, the mower must be placed sideways on the drain side. Let’s not forget that the used oil must be drained into a previously prepared container for subsequent disposal.

· After draining the drain, put the drain plug on the crankcase in place.

· Before filling in fresh engine oil, the mower is placed on a flat surface and the top cover of the oil filler neck opens.

· Fill with fresh engine oil for a lawn mower, for example, Mineral engine oil for a lawn mower Rasenmaher-Oil 30, checking the level with a dipstick.

The oil change process is complete; the mower is ready for use.

How to replace a 2-stroke oil in a lawnmower or trimmer

Oil in a two-stroke engine lives one revolution of the crankshaft. Therefore, the entire oil change process for a two-stroke engine is reduced to the preparation of a fuel-oil mixture with a joint lubrication system and pouring oil into the oil tank when lubricating with a separate system. Semi-synthetic engine oil for 2-stroke engines 2-Takt-Motoroil is suitable for creating a mixture or pouring into a tank

Summarizing the above, we note once again that the choice of motor oil for a fairly simple technique in the form of trimmers and lawn mowers is actually not so simple. For equipment working with green spaces, not only the technical characteristics of the lubricant are important, but also environmental standards are not in the last place. For many years, the Liqui Moly Gardening Program has been successfully preserving the trimmers, lawn mowers and environmentally friendly.
