What Kind Of Oil To Put Into The Lawn Mower

Oil functions

Lawn mower lubricating fluid must be chosen carefully and high quality oils should be preferred. If you save on this consumable liquid, then it will not perform its functions to the full, the mower will fail in a short time and will require expensive repairs. The oil used in the lawn mower performs an important task. It has the following functions:

  • Lubrication of parts that experience high friction during operation;
  • Removal of thermal energy from heated parts;
  • Reduced engine wear;
  • Minimizing the development of such negative phenomena as deposits of various types, the formation of soot and varnish;
  • Protection of parts from the formation and effects of corrosion;
  • Decrease in the toxicity indicator of exhaust gaseous substances;
  • Smoke minimization.

What Kind Of Oil To Put Into The Lawn Mower

The engine of a lawn mower is significantly different from that which is installed in cars and motor vehicles. Therefore, lubricants for THESE units must be used differently. You can not replace the same oil with the second. The consequences for technology can be the most unpredictable.

In a lawn mower engine, the crankshaft is responsible for distributing the oil. The liquid is scooped from the crankcase by parts, which in their shape resemble spoons. The speed of their movement is colossal. Such design features of the motor require the use of oil, which contains high quality additives. These components reduce the ability of the working fluid to foam and become more viscous from high temperatures.

Which is better to choose?

The selection of the right mower oil is based on a large number of factors that must be followed. It doesn’t matter if you choose a lubricant for a gasoline or a self-propelled lawn mower, you cannot use the first oil that comes along. It is also forbidden to choose the most expensive oil or the most popular. The lubricating fluid must be fully adapted to the requirements of your lawn mower.

  • The viscosity of the oil is selected in accordance with the temperature conditions, which are typical for the operation of garden equipment. For summer, when the ambient temperature reaches 30 degrees, it is advisable to use oil from the SAE-30 series. For the off-season it is recommended to use 10W-30 series oil. Synthetic 5W-30 fluid works well at low temperatures.
  • For 2-stroke engines, it is necessary to use a mixture of oil and high-octane gasoline in the ratio recommended by the equipment manufacturer. Usually the ratio is 1/25. According to these figures, 25 ml of gasoline is added for every milliliter of oil. There are exceptions, so you need to study the instructions for the lawn mower.
  • Fluid mixing is NOT required for 4-stroke motors. Suitable for such devices is a simple car fluid. It can be SAE30, 10W40 or SF. The main thing is that the technical and operational characteristics fit the list that the manufacturer recommends. For winter use, the liquid must be chosen with frost-resistant properties.

You cannot experiment and use oil that is not suitable for the existing motor. There is a huge difference between the fluids that are used for different types of motors. For example, a fluid for four-stroke type motors must keep its composition unchanged for a long time. Oil for two-stroke engines should have a minimum amount of mineral components to prevent carbon deposits.

Varieties

To choose the right gardening fluid and always know what to buy, you need to study the existing varieties of oils. First of all, technical oil fluids are separated by chemical composition.

  • Mineral oils are created from the base obtained from refined petroleum products. These fluids are viscous and must change frequently. They are designed for low power motors. Most Recommended for Summer Use.
  • Synthetic fluids are based on special synthetic substances, which include esters. The viscosity is at a low level, a long service life and year-round use. no other type of lubricant can boast such high characteristics. These fluids are ideal for complex machinery that operates in harsh conditions.
  • Semi-synthetic motor oil is created from mineral and synthetic substances. These oils are the middle choice between the two previous fluids. Semi-synthetic oils are ideal for gardening and park equipment, two- and four-stroke engines.

There are several more classifications, which are based on different requirements. The most common API classification. It is supported by different countries and many manufacturers. According to this classification, all engine oils are divided into the following types:

  • TA is the best option for household appliances with a motor up to 50cc. Cm;
  • TB is intended for equipment with a higher power, equipped with a motor of more than 50, but less than 200 cc. Cm;
  • TC is an oil that is intended for motors with increased requirements for the quality of the lubricating fluid; such oil can be safely poured into lawn mowers;
  • TD is designed for outboard motors that are liquid cooled.

Due to the 20% solvent composition, the oil of the two-contact type is capable of mixing well with automotive fuel. In addition, such liquids are capable of completely burning. Lubricants can be painted in various colors. Coloring does not talk about the quality of the oil. Its function is different. it makes it easier for the user to distinguish between lubricant and fuel.

How to choose your lawn mower oil?

Rarely does a private home owner do without a lawn mower. You may not even have a lawn, which needs regular maintenance, but use a lawn mower. This technique, like any other, needs periodic maintenance, such as an oil change. Every lawn mower owner needs to know which liquid can be used for THESE purposes, how to choose it correctly and fill it into the unit.

Manufacturers

When choosing an oil, great attention should be paid to its manufacturer. It is better to choose the brand recommended by the lawn mower manufacturer. In the instructions for the technique, you can find information about the filled oil, the frequency of its replacement and recommendations for choosing a working fluid.

Also, many lawn mower manufacturers release their own oils, which will have to be used for replacement if you want to keep the warranty on the equipment. In addition, the instructions provide general characteristics that the oil must meet. When choosing a replacement fluid, you need to focus on this list. This will allow you to choose the oil that will most closely meet the manufacturer’s requirements.

  • Among all the companies that present their products on the Russian market, Shell Helix Ultra is the best. These oils are popular in all countries. Shell specialists have been working for 40 years on the creation of a unique technology for producing synthetic oil from natural gas. The resulting product is characterized by an improved composition, which has no analogues at this time. The manufacturer adds the necessary additives to the base composition, which makes it possible to obtain products with different characteristics. Such oil must be bought only at specialized points of sale, since low-grade counterfeits are often found.
  • Liqui Moly also represents quality products. The manufacturer produces several product lines, which have different purposes. This range includes products for the maintenance of garden equipment. Such oils are designed for long-term operation of trimmers and lawn mowers, their technical characteristics are developed in accordance with the features of modern technology and the recommendations of manufacturers.

Liqui Moly adds additive packages to lawn mower oils, which are necessary to reduce equipment wear and keep the engine clean. The main advantage of such fluids is environmental friendliness, because they are created on a plant basis. Liqui Moly lawn mower oils meet all environmental standards.

Rasenmaher produces a good mineral type lubricant specially developed for gardening machines. This tool can be used to service 4-stroke engines with different cooling systems. The substance from Rasenmaher can only be used at freezing temperatures. The manufacturer carefully developed and selected additives for their product. The result of such actions was a wide list of functionality:

  • Maintaining the pressure in the system at a stable level;
  • Effective lubrication of all parts that need it;
  • Preservation of the viscosity of the grease throughout the entire service life, until the next change;
  • Providing excellent protection for the engine against natural wear;
  • Minimum evaporation rate.

Replacement recommendations

It is important not only to choose a quality oil that will suit your technique in terms of its characteristics. You also need to know how to properly pour it into the lawn mower. The rules are simple, but must be followed:

  • We turn on the unit and warm up the engine idle for a quarter of an hour;
  • We remove the plug from the tank and substitute a container of the required volume to collect the spent liquid;
  • We tilt the lawn mowers and Drain the waste material;
  • We tighten the plug, put the unit on the most even surface. After that, you can open the hole from above;
  • We fill in a new working fluid, observing the recommendations of the manufacturer of the equipment for the volume, check the fluid level conveniently with a dipstick;
  • When the amount of liquid has reached the desired size, you can tighten the plug.

In most cases, about 500 ml of fresh oil should be used to replace the used fluid. This norm corresponds to most of the units, which are common in Russia. Exceptions, of course, are encountered, therefore you need to study the instructions before replacing the spent fluid.

If your lawnmower is equipped with a two-stroke engine, and this indicates the need to mix the lubricant with gasoline, then this should be done immediately before replacement. It is impossible to make such a composition with a margin, since due to a chemical reaction, the mixture loses its properties. The approximate shelf life is no more than a month. Only components will be damaged from such actions.

For how to change the oil in your lawn mower, see the following.

General Guidelines for Choosing Lawn Mower Oil

Based on the above design features of the engines, it is best to use a special lawn mower oil for lubrication, and it should be suitable for the temperature conditions in which the unit will be used. The best option is a specialized grease of the SAE 30 class.It is used at temperatures above 5 degrees.

If a special one is not available, then automotive lubricants of the class can be used:

  • SAE 15W-40
  • SAE 20W-50

These lubricants are also designed mainly for positive ambient temperatures and a maximum value above 35 degrees.

By the type of lubricant. mineral and semi-synthetic are allowed. Fully synthetic would be too expensive. The quality level of performance properties according to API. “SF”, “SG”, “SH”, “SJ” and higher. For four-stroke garden machinery engines, the label must be marked “4T”.

Lawn mower features

The engine oil in a lawn mower engine is distributed by the crankshaft: it is scooped up from the crankcase and sprayed onto the parts. Due to this design, the viscosity of the lubricant should be sufficient to retain the oil film on the parts, at the same time it should not be too thick to interfere with the movement of parts or form a hard crust.

On the other hand, lawn mowers operate mainly in positive ambient temperatures and the load on their engines is not as severe as in car engines. Lawn mowers most often DO NOT require a “cold start” in the cold, which greatly reduces the life of the car engine and requires low-temperature properties from lubrication.

The first filling is intended for running in the engine. after five hours of operation, it is replaced, after which it is possible to work on the new grease for the whole season. In the future, the replacement is done according to the regulations after a certain number of engine hours, or it is drained at the end of the summer season and a new one is poured the next year.

Recommendations for the selection of oils from specific manufacturers

Manufacturers of lawn mowers in the instructions for them must indicate the type that is used in their technology, as well as the frequency of oil changes, as a rule, in engine hours. Usually manufacturers indicate their branded lubricants and they should be used if you want to keep the warranty on the equipment. But often manufacturers also indicate the general characteristics of lubricants and then you can choose similar lubricants from more widely available automotive oils.

Best for any engine is the one recommended by the manufacturer. Shell Helix Ultra is world famous. For 40 years Shell has been developing a new technology for producing synthetic oil from natural gas. Pureplus technology has resulted in an improved base oil composition. On its basis, with the addition of the necessary additives, the leading manufacturers Recommended for their equipment receive.

What kind of oil to pour into the lawn mower?

The internal combustion engines used in the lawn mower come in two and four strokes. When changing the engine oil in lawn mower engines, the question arises in the owners. what kind of engine oil to fill in the lawn mower? Today we will analyze this issue in detail and start first with four-stroke engines.

Changing the engine oil in a two-stroke lawnmower

The two-stroke engine is usually mounted on trimmers (manual grass clippers). These devices are small in size and weight, so the number of details in them is minimal. They have a separate oil reservoir and you need to prepare a mixture of gasoline and oil. Here, amateur performance is NOT appropriate. it is necessary to use only a special one for two-stroke engines and mix it with gasoline in the proportions specified in the operating instructions for the trimmer.

Once again, Pay attention. the canister with oil for two-stroke engines MUST be marked “2T”!

The fuel mixture for two-stroke engines is prepared as follows:

  • The exact amount of gasoline is poured into the canister (for example, for a trimmer of 5 liters),
  • Then, using a dispenser, add oil (semi-synthetic. 100 milliliters)
  • Cover with a lid and mix well

The finished fuel mixture can be stored for no more than two weeks in a metal or polypropylene container.

Do not use plastic bottles for storage! Polyethylene dissolves in gasoline and then, getting into the combustion chamber, increases carbon deposits in the engine. With prolonged storage of the fuel mixture, it loses its properties due to chemical reactions. There is an increased risk that the engine will not start on old fuel.

We hope our review helped answer the question that worries you. what kind of oil should you put in a lawn mower? We ask you to share your best practices for replacing engine oil in a lawn mower under the review in the comments below.

What kind of oil to pour into the lawn mower?

Everyone knows that a car engine requires special care to ensure a long and trouble-free engine life. The same rule applies to the motor of a gasoline lawn mower: depending on whether you have a trimmer or a large four-wheel mower, you will be faced with the problem of choosing an oil. And what are the basic requirements for lawn mower engine oil?

How to choose your lawn mower oil?

As with any unit, the lawn mower has an instruction in which not only the main characteristics of the tool are prescribed, but also the rules for caring for it. So, the instructions will say that only specialized oil should be used for lawn mowers. And some manufacturers insist on using the same brand of oil as the lawn mower itself.

In fact, this fact turns out to be just a marketing ploy of manufacturers, and both automobile and motorcycle engine oil for four-stroke engines can be suitable for a lawn mower. It is enough just to follow the basic rules:

The oil must be mineral or semi-synthetic. Fully synthetic oil can burn the engine, so it is best NOT to use it at all. Mineral oil produces a lot of sludge when the mower is running, so we advise you to opt for semi-synthetic oil. In addition, mineral oil is difficult to find today.

The viscosity of the oil should not exceed SAE 30 or 10w30, and the quality category should vary between SE and SJ. viscous oil can disrupt engine performance, however, less viscous oil can also be affected. All these indicators are necessarily indicated on the packaging.

Select oil based on operating temperature conditions. If you mow in cold weather, the viscosity of the oil may be higher than the above, but the next time you turn on you will have to change the oil to the correct one.

In lawn mowers with four-stroke engines, oil is poured into a special crankcase and is never mixed with gasoline, since the design of such a gasoline lawn mower does NOT imply a mixture of oil and fuel. On the contrary, it can be a prerequisite for engine breakdown. It is enough to change the oil once a season, as the crankcase usually holds from 450 to 600 ml of oil. this is enough for processing large areas. However, be lazy to check the oil level before each insertion of the tool.

How oil is applied to a two-stroke lawn mower?

As a rule, the two-stroke engine is mounted on trim tabs, and since their design does NOT imply the presence of unnecessary parts, a separate oil container is not provided. What should be done in this case? Prepares fuel mixture.
For lawnmowers with a two-stroke engine, the same rules apply as for their larger counterparts, with one exception. oil must be bought for units with a two-stroke engine.

Each trimmer (or instructions for it) indicates the mixing ratio of fuel and oil: from 1:32 to 1:35. This rule is only valid for mineral oil! And since it is quite difficult to find it now, and the price may frighten off, semi-synthetic or even synthetic oil is most often used. Please note that the mixing proportions in this case change, and become. 1:50. If in doubt, carefully study the packaging of the oil, it usually contains these data. You should focus on them. To prepare the mixture, it is enough to pour in 100 ml of oil into five liters of gasoline, this should be enough for a whole season of regular squint. If not, repeat the procedure.

4-Stroke Lawnmower Oils

Lawn mowers have long taken their place among the necessary equipment in the owners of country and private houses, as well as employees of park facilities. In the summer, this technique is used quite intensively. For reliable and durable operation of lawn mower engines, the quality of fuels and lubricants, in particular, oils, is of great importance. In oils for 4-stroke engines of this type of gardening machines, it is described in this article.

How often do you need to change the lubricant?

As noted above, the operating instructions for garden equipment with a 4-stroke engine must indicate the frequency of oil changes. But if there are instructions, then they are guided first of all by the number of hours that the technique has worked (engine hours). Every 50-60 hours worked, you need to change the oil in the engine.

However, in the case when the site is small and you can process it in no more than one hour, it is unlikely that for the entire spring-summer season the lawn mower will work even half the operating hours of the norm, unless you rent it out to neighbors. Then the oil must be changed when the equipment is preserved in the fall before the winter period.

Why do you need lubricant?

Gasoline engines of lawn mowers are internal combustion engines (ICE), in which the DRIVING force transmitted from the internal combustion engine to the working bodies (cutting knives) is generated by the energy generated in the combustion chamber of the cylinder when the fuel mixture ignites. As a result of the ignition, the gases expand, forcing the piston to move, which is associated with the mechanism for further transfer of energy to the final organ, that is, in this case, to the lawn mower knives.

In the engine, therefore, many large and small parts are mated, which need lubrication in order to, if not completely prevent their abrasion, destruction, wear, then at least as much as possible slow down these processes, negative for the mechanism.

But over time, this cannot be avoided, since the development of gaps in the mates still occurs. And the better the oil, the longer the service life of the garden equipment will be. In addition, with the help of high-quality lubricants, the following positive phenomena occur:

  • Better cooling of the engine and its parts, which prevents overheating and thermal shock;
  • Engine operation is guaranteed at high loads and with a long period of time continuously Mowing grass;
  • Provides protection from corrosion of internal engine parts during seasonal downtime.

Oil change

Changing the lubricant in a lawn mower engine is not as difficult as changing the oil in a car. Everything is much simpler here. The work algorithm is as follows.

  • Prepare enough fresh oil for replacement. Usually, the lubrication system of many lawn mowers is filled with NOT more than 0.6 liters of oil.
  • Start the unit and let it idle for a few minutes to warm up the oil, so that it becomes more liquid. This promotes better drainage.
  • Switch off the engine and place an empty container under the drain hole from the crankcase to collect the used oil.
  • Unscrew the drain plug and let all the oil drain. It is recommended to tilt the device (if possible or appropriate) towards the drain.
  • Tighten the plug and move the car to a level surface.
  • Open the filling hole on the Shrovetide tank and fill it to the required level, which is controlled by a dipstick.
  • Tighten the tank cap.

Features of the four-stroke engine

Lawn mower gasoline engines are divided into two groups: two-stroke and four-stroke. Their difference in the way of filling the oil is as follows:

  • Lubricant for two-stroke engines must be pre-mixed with gasoline in a separate container and in a certain ratio, mixed thoroughly, and after all this, it must be poured into the fuel tank of the car;
  • Lubricant and gasoline for four-stroke are NOT pre-mixed. these liquids are poured into separate tanks and work separately, each according to its own system.

Based on this circumstance, the requirement for oil is also special here. It should retain its properties for a long period, when, as for the lubricating composition of a two-stroke motor, the main quality criterion, in addition to the basic properties, is the ability to burn without a trace, Do not leave carbon deposits and deposits.

Selection recommendations

It is best to use a specially designed oil for the 4-stroke engines of lawn mowers, in accordance with the ambient temperatures in which the equipment will be used. For example, specialized grease grades 10W40 and SAE30 are quite suitable for four-stroke mowers in terms of their operational parameters, which can be used at ambient temperatures in the range from 5 to 45 degrees Celsius.

In the absence of specialized oils, you can use other classes of oils used for cars. These can be grades SAE 15W40 and SAE 20W50, which are also used at positive temperatures, but only their threshold is 10 degrees lower than specialized ones (up to 35 degrees). And also for 90% of the available models of four-stroke lawn mowers, an oil of SF composition will do.

The container with engine oil for a four-stroke lawn mower must be marked with the “4T” sign. Synthetic, semi-synthetic and mineral oils can be used. But most often they use semi-synthetic or mineral oil, since synthetic oil is very expensive.

And in order not to guess what oil to fill in the engine of your mower model, it is better to look at the instructions. The required type of oil and the frequency of its replacement are indicated there. It is recommended to use only the types of oils specified by the manufacturer before the expiration of the warranty repair period in order to maintain the issued guarantees. And then you can choose something more affordable, but, of course, not inferior in quality to branded oils. You should not save on oil quality.

What oil should not be poured?

Do not fill the four-stroke engine of the lawn mower with lubricant intended for two-stroke analogs (on the labels of oil containers for such engines, the marking “2T” is put). However, you cannot do this and vice versa. In addition, it is unacceptable to fill in the liquid that was stored in plastic bottles from drinking water.

For how to change the oil in a four-stroke lawnmower, see the following.
