What oil for the lawn mower is a four -stroke engine. The choice of oil manufacturer

What gasoline and oil to pour into a lawn mower

Self.propelled gasoline lawn mower is a complex technique that can mow grass, and also perform other functions. Due to the fact that it is equipped with an engine, physically weak people can also use it. This technique needs to be regularly taken care of. One of the necessary procedures is to replace the oil. Everyone who has such a device should know what gasoline to fill in the lawn mower. We must be able to choose the right fuel for your model, it can be Al-ko (al-ko), Daewoo, Honda (Honda), Husqvarna (Husqvarna), Patriot (Patriot), Stiga, Champion, etc.D.

4-stroke engines, unlike 2-tact, have a more complex design. Four.stroke lawn mowers are more powerful, therefore they have greater efficiency. Such engines are more economical. They work cleaner, as they provide good control of the absorption cycles and air release.

With a two-stroke cycle, due to the fact that the fuel comes out during the supply and compression, some of it is consumed idle. This does not happen in another engine, gasoline is drawn into a closed system. 2-stroke engines are refueled by oil and gas mixtures. which reduces the effectiveness of combustion, increases the emission in the form of burned harmful oil. They mix fuel and oil, this adversely affects the service life. Due to the general circulation, such gas mowers can work in any conditions.

A 4-step engine has a specialized lubricant system. In it, the injection of motor oil occurs from a separate container. The oil is located separately from the fuel. Therefore, the motor is lubricated better. Car engines mainly operate on a four.stroke cycle.

The simplicity of the design and the presence of a smaller number of moving elements in 2-step motorcosas make their maintenance and repair easier. They are much easier.

The cleanest operation of four.stroke engines and the presence of a special lubricant system leads to the fact that the details of such equipment wear out less, serve longer.

In two-stroke engines due to the fact that after burning fuel and oil, a dirty combustion product is formed, there is a greater wear of the engine system. As a result, it fails faster. The cost of lawn mowers with such an engine is lower, but in an hour of operation it increases due to the fact that you will have to additionally spend funds on oil, as well as due to low fuel efficiency.

The choice of fuel

Having bought a new motorcycle, the owner who has never used it, he cannot know what gasoline to refuel the lawn mower, how to choose the right fuel, how it is changed. First of all, it is necessary to clarify the type of engine that is equipped with this technique. Experts do not advise operating 2 types of motor on fuel, which has the same composition. The gasoline engine should operate on gasoline, which must be diluted with engine oil. It will protect nozzles and valves, protect them from a quick failure.

The correct operation of the engine of a particular lawn mower will provide a suitable type of oil that happens:

What is the difference between two.stroke oil and a four.stroke

Some types of motor oil are designed for four.stroke power units, while others for two.stroke. They are not interchangeable: various requirements are imposed on the lubricants for engines with different working cycle.

So, oil for four.stroke high.speed engines, where a forced lubrication system is used, is designed for prolonged exposure and is designed to provide a more stable cover of parts. In two.stroke engines, the oil comes with the fuel and should instantly dissolve in it, freely burning with a minimum of sediments in the form of soot and ash.

Therefore, a characteristic feature of two.stroke oils is their good cleaning and minimal aggressive additives. They, unlike a four.stroke fluid, do not contain ash, anti.zadir and anti.ine additives. This allows them to burn almost completely with the fuel without the formation of soot and the toxicity of the exhaust.

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

A feature of oils for four-stroke engines is many metal-organic additives that are aimed at improving their physical and mechanical properties and increasing the efficiency of action. And if you pour such a mixture into an engine with a working cycle for two tacts, this will lead to the formation of ash deposits on the surface of the piston and the walls of the combustion chamber. The increased accumulation of deposits, in turn, can provoke the appearance of various troubles, which can be eliminated only by making a complex and expensive repair of the motor, motor unit or motorized carrier. A lot of harm is caused by soot, which clogs the air filter and settles in the grooves of the piston rings, if you use the inappropriate oil product. The accumulation of soot is fraught with the loss of the mobility of the rings, and this is a direct path to reducing the power of the engine of the walk.behind tractor, the deterioration of its operation, and even the complete failure.

Classification of motor oils

The most important parameters of motor oil are the degree of viscosity and the temperature range in which it can be used.

In the labeling, the number in front of the letter “W” indicates the value of the temperature at which the liquid thickens. The number after the letter indicates the maximum temperature at which the liquid provides uninterrupted operation of the engine. These indicators must comply with the fact that the instructions for the operation of the garden motor.cultivator.

It should also be borne in mind that in winter and summer you need to use different high.skinned lubricants:

Small oil products at high temperatures will quickly evaporate and will not be able to provide a full lubrication of mechanisms. Too thick liquid will become an obstacle to starting the motor at low air temperatures.

The chemical composition of the basis of the lubricant is also important, as it affects the properties of the product and determines its effect.

Mineral motor oil:

• provides a decrease in friction;
• reduces the formation of sediment and soot;
• reduces wear of working parts;
• does not form harmful exhausts and does not pollute the air.

Synthetics contains additives that prevent non.hawk formation and protect the power unit from wear. Semi.synthetics is made by mixing mineral and synthetic foundations using special additives.

Advantages of synthetic and semi.synthetic motor fluid:

For 4-clock engines of motoblocks, cultivators and other garden equipment, oil products with SAE-30 labeling are excellent, having high viscosity and intended for summer use.

They can be made on a mineral or synthetic basis and accommodate various additives. The liquid with such a marking reliably protects the rubbing surfaces from corrosion and rapid wear. The oil differs in that the engine service extends.

Analogue of the summer SAE-30 can be any all-season oil, in the designation of which the second number is “30”. For example, a “5W-30” marking liquid has similar characteristics when used in the summer, but it can also be poured in the winter when the air temperature is not lower than.35 about s. Lubrication “10W-30” also has a similar SAE-30 properties when used in the warm season. But its working range is limited by temperature.25 about s.

Differences in engines in lubrication methods

A significant point is the difference in the method of lubricating two.stroke and four.stroke internal combustion engines: the former requires refueling with not clean gasoline, but its mixture in the necessary proportion with oil. She, connecting with the air, circulates in the piston node, while lubricating the walls of the cylinder, crankshaft bearings and connecting rods, as well as the pistons themselves. Когда топливная смесь загорается, то масло, мельчайшими каплями входящее в ее состав, также сгорает. Combustion products come out in the form of waste gas. In practice, oil mushrooms with a two.stroke engine is mixed with gasoline in certain proportional ratios.

There are 2-stroke engines with a separate intake of these components of the fuel mixture, but on mowers this more perfect option is not installed.

When the engine is 4-stroke, the oil is supplied separately, without mixing with gas. Almost lubrication is implemented due to the presence of pipelines, oil pump, valves, filter. The latter is designed to clean the oil from small particles of metal formed during the wear of the parts.

It turns out that in 2-stroke engines the oil burns during operation, but in 4-stroke there is no, remaining a long period to circulate in the system. Because of this, the requirements for its operational properties differ. After combustion, two-stroke engine oil should leave the minimum possible amount of soot, and for four-stroke units it is necessary for the lubricant used for a long time to maintain its initial physicochemical indicators.

Suitable oil and gasoline for refueling a 2-stroke engine

Two.stroke gasoline engines are designed to work on the fuel mixture. Oil replacement in the lawn mower is not separately produced. it is proportionally mixed with gasoline. In this case, only a properly prepared fuel composition must be poured into the motor system.

Pour oil on the principle of “the higher its price, the better for the operation of the mechanism” you cannot. Suitable for 2-stroke ICE varieties of oil compositions according to the method of their production are divided into such groups:

The lubricating properties of the material depend on the basis, its ability to remain in a liquid state when the temperature is reduced, significantly without increasing the viscosity at the same time. The composition of the lubricant includes approximately 5-15 % of a variety of additives. They are designed to increase the practical effectiveness of the tool used. The additives allow:

• slow down the course of corrosion of metal surfaces associated with redox reactions;
• increase the thermal resistance of the parts;
• stabilize the viscosity of the substance at the same level when temperatures in a certain range.

Manufacturers of lawn mowers in the instructions indicate that brand of lubricant, which is the best option for the operated unit. If you get it problematic, it is possible to change the oil for a similar composition designed for 2-tact DIS. In this case, the level of viscosity must necessarily correspond to the recommended manufacturer of the product of its value.

Gasoline is the main voluminous component of the suitable fuel mixture. Its brand should comply with the lawn mower recommended in the operating instructions. The time of its combustion depends on the size of the octane number of gasoline: the larger this number, the longer the fuel burns.

If you use gasoline of a higher brand than recommended, then a two.stroke internal combustion engine will fail faster.

What gasoline to fill

Gasoline for the lawn mower. the second element of the fuel mixture. Its brand is selected taking into account the recommendations of the manufacturer described in the passport to the unit. The duration of the fuel and resistance to detonation indicates the value of the octane number: the higher the number, the longer the fuel burns out. So, at gas stations you can buy such brands of oil products:

AI-92 has a greater tendency to detonation.

When using fuel with a higher indicator of the octane number than stated in the instructions, in units with 2-stroke engines a motor is damaged, with a smaller parameter-a piston group.

The mixture is prepared before operation in the proportion, which is indicated on the cover of the gasoline tank:

This means that for 1 liter of fuel you need 20 ml of oil fluid.

Manufacturers of benzocystems with a two.stroke engine (for example, Patriot PT 555 or Champion T336) indicate the desired proportion for the preparation of the fuel mixture in the instrumentation instructions. For the first model, a ratio of 32: 1 is proposed, for the second. 50: 1.

The lawn mower with a 4-stroke engine does not require preliminary preparation of oil products. The equipment device provides for 2 containers. It is necessary to pour gasoline into the tank, and the oil fluid in the drain hole on the crankcase.

Lessacle clock requirements

Engines in small agricultural machinery differ from automobile, therefore, the lubricant should differ. It is impossible to pour a mixture intended for machines or motorcycles into a mower. Even if it does without malfunctions, the lawn mower will most likely begin to work worse: the liquid not designed for this type of technology will not be able to cope well with its functions. Therefore, they recommend using special oils designed for garden equipment.

Recommendations for storing the finished fuel mixture for a trimmer for grass

After refueling a trimmer for grass, many put off the mixture remaining in the bottle until the next time. Sometimes this next time does not come soon, and stretches until next year. It is impossible to store the finished mixture for so long, since the decomposition of the oil occurs. After preparing the mixture, it must be consumed for 1-2 weeks. In addition, it is also impossible to store the tool for a long time with a fuel mixture flooded into the tank, since the effect will be similar. To prevent unforeseen circumstances, it is recommended to take into account the following recommendations for storing the finished mixture of gasoline with oil:

• Prepare the fuel mixture in such an amount that will be used. If you do not know how much fuel you use, then it is better to cook less
• If in the tank of a trimmer for grass (when the tool is hidden until the next season) there remains a fuel mixture, then it must be fully consumed or drained
• Before adding the cooked mixture to the tank, you need to thoroughly stir it
• Store the finished mixture in a tightly twisting container, as well as in a place limited to the effects of sunlight

Subject to all recommendations, the service life of a trimmer for grass will be no less than indicated in the instructions. The use of qualitative consumables in pairs in compliance with the recommendations for the preparation of the mixture in the trimmer for grass will entail a long and effective service of gasoline tools.

Some important nuances

It is important to remember that you can not store the resulting mixture for a long time. The storage itself is carried out only in a dark cool room without direct sunlight. Even if it is supposed to leave the mixture for several days before using it, you should put the canister on the ground to remove the effect. Tara for the mixture should only be iron, storage in plastic is not allowed.

In no case should you use a container from under the drinks (water, juices or lemonades) for storing gasoline and oils). The basis of polyethylene.ethnication, on which a bottle for food is based, does not have resistance to petroleum products and additives included in them.

Features of lawn mowers

Despite the fact that in the general design four.stroke lawns of lawn mowers are similar to automobile, they still have important differences: in order to reduce the cost of the product, the gas mowing is excluded by the oil pump and the oil supply system is generally excluded, this increases the requirements for the viscosity of garden equipment used in motors.

The engine oil in the engine of the lawn mower is distributed using a crankshaft: scooped up from the crankcase and sprayed to the details. Due to this design, the viscosity of the lubricant should be sufficient to hold the oil film on the details, 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, the lawn mower operates mainly at positive ambient temperatures and the load on their engines is not as serious as in automobile engines. For lawnmands, the “cold start” is most often not required in the cold, which greatly reduces the car’s engine resource and requires low.temperature properties from lubrication.

On the contrary, the lawn mowers, as a rule, have air cooling and therefore the temperature of their engine is higher than that of car engines with liquid cooling.

The first refueling is designed to run the engine. after five hours of operation it is replaced, after which you can work on a new lubricant all season. In the future, the replacement is made according to the regulations through a certain number of motorcycle hours, or it is drained at the end of the summer season and the next year is filled with a new.

General recommendations for the choice of oil for lawn mowers

Based on the above features of the engine design, it is best to use special oil for lawn mowers for lubrication, and it must comply with the temperature conditions in which the unit will be used. The best option is the specialized lubrication of the SAE 30 class. It is used at temperatures above 5 degrees.

If the special is not available, then you can use car lubricants of the class:

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

By the type of lubricating fluid. mineral and semi.synthetic. Completely synthetic will be too expensive. The quality level of operational properties for the API. “SF”, “SG”, “SH”, “SJ” and above. For four.stroke engines of garden equipment on the label, there should be a marking “4t”.

Types of oil mushrooms

So, what kind of oil to pour into a lawn mower? One factor to remember is the climate of the place where you are. Different oils work best at different temperatures, and not all are suitable for your equipment.

Be sure to read the operating manual to get the manufacturer‘s recommendations for your lawn mower. We compiled this leadership to help you choose one of the common types of oil.

SAE-30

This is the most commonly used oil mowing oil variety, as it is ideal for temperatures from 4 ° C to 37 ° C. If the street is colder than 4 degrees, you hardly need to cut the lawn. In general, this is the best choice for inexpensive oil, which can be used in a lawn mower from spring to autumn.

SAE 10W-30

This oil has a wider temperature range, from.17 ° C to 37 ° C. Since this type of oil withstands lower temperatures, it can also be used in other engines. For example in snowmers. When used at temperatures above 28 degrees, oil consumption may increase.

SAE 5W-30

This oil works best at a temperature below 4 ° C. Thus, it is ideal for your snow removal, but not for your lawn mower.

Synthetic SAE 5W-30

The synthetic version of the 5W-30 oil has a wide range of temperatures in which it can be used from.28 to 48 ° C. This oil works all year round. This oil improves the engine start and reduces the consumption, but it also costs more.

Synthetic SAE 15W-50

This oil also has a range of high temperatures, from.6 up to 54 ° C, but it works best at higher temperatures. It is usually used for commercial equipment for haircuts.

Ordinary oil against synthetic oil

Which is better for your engine: ordinary oil or synthetic oil? Generally speaking, ordinary oil is perfect. If you use oil under proper conditions, it will provide protection and lubrication at an affordable price.

However, synthetic oil provides better protection in a wider temperature range, but has a higher price. Synthetic oil collects more dirt, so when changing the oil, these particles will be removed from your lawn mower. This can lead to an increase in performance in general.

Whatever option you choose, it is important to check the level and add oil throughout the season, and also completely change it after about 50 hours of work.
