Like many other machines, lawn mowers also need to be checked periodically. To ensure smooth engine operation, it is very important to check and change the oil that the lawn mower is using.
In this article, Wightmansfarms will answer the questions: “What kind of oil does a lawn mower take?“; “What should be kept in mind when choosing oil for lawn mowers?” and many more. Those are useful tips that you need to know to keep your lawn mower’s engine stable and durable.
How Much Oil Does A Lawn Mower Take?
Not only lawn mowers, but engines used on almost all equipment and machines also need oil to operate properly. To find out how much oil a lawn mower takes after defining what kind of oil does a lawn mower take, you should get to know the role of oil in the explosive operation of an internal combustion engine.
When the engine is in operation, the piston slides into the cylinder, and thanks to the ignition system, a mixture of gasoline and air is burned to create force. This force is transmitted to the handwheel, which is then transmitted to other parts for the device to operate.
During that process, the friction generated between the metal parts of the engine is extremely large. So the oil will lubricate and cool down the engine when it starts.
Currently, the ratio of gasoline mixed with oil for lawn mowers will usually be one of three ratios, as follows:
- 50:1 (50 liters of gasoline mixed with 1 liter of oil)
- 40:1 (40 liters of gasoline mixed with 1 liter of oil)
- 25:1 (25 liters of gasoline mixed with 1 liter of oil).
The 50:1 ratio is said to be the most popular. The ratio of gasoline to oil depends quite a lot on the level of use of the engine and the quality of the oil. If the oil is of poor quality or the user uses the lawn mower frequently, it is necessary to mix gasoline with more oil to protect the device from the effects of friction.
However, these ratios are not necessarily the best for all types of lawn mowers. When you buy a machine, you will receive the manufacturer’s manual. Referring to the manual, you should check if there is a regulation on the ratio of gasoline to oil and follow that guide.
What Kind Of Oil Does A Lawn Mower Take?
So, what kind of oil does a lawn mower take? Choosing the oil that best suits your lawn mower depends on the model, temperature, and frequency of use. There are 4 main groups of oils used for lawn mowers as below.
Single Grade Oil
What is single grade oil? A single grade oil, as defined by the American Society of Engineers (SAE), is a lubricant that only meets a single requirement. At the same time, this type of oil cannot use a polymer viscosity improver (viscosity modifier).
Single grade oil can only be useful at high temperatures. When the temperature in the machine is low, the oil will thicken, making lubrication difficult. You will be unable to start the lawn mower, or it will take longer to start.
Multi Grade Oil
Multi grade oils, according to SAE (the American Society of Engineers), are lubricants that can withstand a wider temperature range than single-grade oils. Basically, this oil can be used for both high and low-temperature weather.
Multi grade oils are made by blending low-viscosity oils with special additives called viscosity index improvers. This multi grade oil, thanks to its additive composition, combines with the original viscosity to start up the engines even at low temperatures.
Synthetic Blend Oil
Synthetic oil is a synthetic lubricant containing a more refined base oil than that used in conventional mineral oils, providing perfect protection and maximum performance. Synthetic engine oils provide many benefits that keep engines running at optimum performance for many years.
The performance characteristics of synthetic oils are stronger, especially in terms of low temperature pumpability, high temperature stability and protection against deposits. These properties result in less engine wear, increased fuel economy and longer engine life.
Full Synthetic Oil
Fully synthetic Oil is a lubricant produced in chemical plants to meet the exact requirements of modern engines. This makes synthetic oils expensive, but because they are manufactured with precision technology, they offer optimum performance and protection. Synthetic oils have the ability to work reliably at high and very low temperatures.
Synthetic base oils have high lubricating properties, are specialized, have a long service life, and have a low loss. However, synthetic lubricants also have disadvantages, such as low compatibility with sealing materials (gaskets, seals), little compatibility with other oils, and being expensive.
Can You Use Car Oil In A Lawn Mower?
You can use car oil in a lawn mower. However, this does not mean that you can use one car oil for all lawn mowers. If your lawn mower has a 2-stroke engine, you must use a separate oil. The situation is similar with lawn mowers with 4-stroke engines. You need to read the user manual carefully to choose the right oil.
What Motor Oil To Use In My Lawn Mower?
Some common oils commonly used include SAE 10W-30 (varying temperature range), Synthetic SAE 5W-30 (all temperatures), SAE 5W-30 (cold temperature), Vanguard 15W-50 (varying temperature range) ), SAE 30 (warm temperature), etc. This depends on the climate in your area to decide what kind of oil does a lawn mower take.
Generally, SAE 30 is used for circuit breakers with 4-stroke engines. This oil is suitable for small engines such as lawn mowers, tractors, electricity generators, and so on. By using this oil, you can save on maintenance costs, maintain power and performance, and prolong oil change intervals.
How To Change Oil In A Lawn Mower?
Here’s how to change oil in 2-stroke lawn mowers:
- Step 1: Prepare a container for the fuel mixture, which can be a tank or can. Requires that the container is clean and has more space than the volume of the mixture to be mixed, to avoid spillage or loss during mixing.
- Step 2: Mix gasoline into the oil with the ratio of gasoline to the lawn mower as mentioned above. When mixing, always pour gasoline into the oil and absolutely do not pour in the opposite direction. During the pouring process, gently and gently shake the container so that the solution is mixed well before use.
For 4-stroke lawn mowers, follow these steps:
- Step 1: Newly purchased 4-stroke lawn mowers will have maintenance oil available, you need to drain all this oil out to change the oil completely.
- Step 2: Run the engines 3 to 5 liters of gasoline and then change the oil for the first time after 5 hours.
- The 2nd oil change is after the next 25 hours
- The 3rd change is after 50 hours
- The next time, every 50 hours, change 1 time.
How Often To Change Lawn Mower Oil?
The frequency of oil changes should be flexible, depending on the density of use that changes reasonably. For example, if you do not use the full 50 hours but it has been a long time since you have used it, you should also change the oil for the lawn mower.
How To Drain Oil From A Lawn Mower?
Before changing the oil, you can drain the oil from your lawn mower as follows:
- Step 1: To drain the oil, we proceed to disassemble the oil dipstick and the oil drain bolt. To clean the old oil in the cavity should be strict to one side and use a pneumatic spray gun to push the excess oil out.
- Step 2: Insert the bolt and tighten
- Step 3: Tighten the dipstick. Before that, you should clean and thoroughly clean the grease stick to get rid of the old oil.
