The most important organ of any lawn mower is the engine. In the electrical unit, the motor runs on the mains, in the battery pack. The most popular mowers are equipped with gasoline internal combustion engines, which can be 2- or 4-stroke.
Each of them consists of many parts and mechanisms that are in a state of continuous friction. This leads to the heating of the elements and their rapid failure.
It is precisely this problem that oil is designed to solve. Every owner of the lawn mower is required to know What Kind Of Oil For Lawn Mower, correctly choose it, and fill it into the component.
What Kind Of Oil For Lawn Mower?
Choosing the kind of oil for a lawn mower is based on many factors that must be followed. It does not matter if you choose oil for gasoline or a self-propelled lawn mower. You cannot use the first oil that comes along. It is also forbidden to select the most expensive oil or the most popular. Here are factors to follow.
To choose the kind of oil for lawn mower and know what to buy, you need to study the existing varieties of oils. To begin with, technical fluids of oil are separated by the chemical composition. This include:
Mineral oils: They are created from the base obtained from refined petroleum products. These oils are viscous and must be changed frequently. They are designed for low-power motors and most recommended for summer use.
Synthetic oils: They are based on particular synthetic substances, which include esters. The viscosity is at a low level, long service life and the whole year use. No other type of oil can boast such the high features. These oils are best for demanding applications in harsh environments.
Semi-synthetic motor oils: These oils are created from synthetic and mineral type substances. They’re the middle option between the previous two fluids. Ideally, semi-synthetic oils are fit for park and garden equipment, and four- and two-stroke engines.
Great attention should be paid to its manufacturer when choosing what kind of oil for the lawn mower. It is better to select 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 manufacturers of the lawn mower release their oils, which will have to be used for replacement if you want to maintain the warranty on the equipment.
In addition, the instructions provide general characteristics that the oil must meet. When choosing the oil, you need to focus on this list. This will allow you to select the oil, which will closely resemble the requirements from the manufacturer.
The oil is selected following the temperature conditions typical for operating a lawn mower in terms of viscosity. When the temperature reaches about 30 degrees, SAE-30 series for summer is advisable to use. For the off-season, it is recommended to use 10W-30 series oil. At low temperatures, Synthetic 5W-30 fluid works well.
4. 2-stroke engines
For 2-stroke engines, it is necessary to use a mixture of oil and high-octane gasoline in the ratio recommended by the lawn mower 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.
5. 4-stroke engines
In the case of 4-stroke engines, mixing of oils is not required. A simple lawn mower fluid is optimal for such mechanisms. It can be SAE30, 10W40, or SF.
The main thing is that the technical and operational properties match the list recommended by the manufacturer. For winter use, choose the oil with frost-resistant properties.
Functions of Oil for The Lawn Mower
The oil used in a lawn mower has a vital role to play. These are some of the functions:
- Lubrication of parts that experience a high frictional force during operation
- Removal of the thermal energy from the heated parts
- Minimizing the negative phenomena development as deposits of different types and the accumulation of varnish and soot
- Reducing engine wear
- Protection of parts from the formation and effects of corrosion
- Decrease in the toxicity index of exhaust gaseous substances
- Minimizing the amount of smoke
How to Check Lawn Mower Oil
Check the engine oil level before every haircut and recheck it after eight hours of use. Use the dipstick to check the oil level. Tighten the dipstick securely in the tube before removing the dipstick.
The oil level should be at the full line on the dipstick. If more oil is required, pour it slowly through the dipstick tube, careful not to overfill. When you are done, screw the cap tightly onto the dipstick tube.
Oil Replacement Recommendations
Choosing a quality oil that will suit your technique in terms of its characteristics is essential, but you also need to know how to pour it into the mower properly. Here are the simple rules, which must be followed.
- Turn on the unit and warm up the engine idle for a quarter of an hour
- Remove the tank plug and replace the container of the volume required to collect the waste liquid
- Tilt the lawn mower and drain the waste material
- Twist the plug and put the unit on the even surface. After that, you can open the hole from above
- Fill in new working oil, observing the manufacturer’s recommendations of the lawn mower regarding the volume. Then check the level of oil conveniently using the dipstick
- When the amount of oil has reached the required volume, you can tighten the plug.
The owner of the private home cannot do without the lawn mower. If you have one, there will be need for regular maintenance. This method, like any other, requires periodic maintenance, such as an oil change.
Each lawn mower owner needs to know which oil to use. With the above factors, you will know what kind of oil is for a lawn mower.
