Lawnmowers keep your lawn in the best shape; taking a little care of it can go a long way in ensuring its longevity and dependability. Cleaning the lawn mower and taking care of the aesthetics is all good but what really matters is what you put inside the engine. The best oil for the lawn mower will keep it in the best condition and will extend its service life considerably.
The wrong oil can stall your lawnmower and can do irreversible damage to the engine. The right one ensures smooth, efficient operation and long engine life. So, how to select the best oil for a lawn mower? With so many options out there, selecting the right one can be a hassle.
Things to Look Out For The Best Oil For Lawn Mower
Here are a few things that you need to keep in mind while making the purchase.
Lawn Mower Oil Types
Engine oil is rated according to the temperatures that it can safely withstand. Depending on the engine and the type of climate that you have, your engine can work on any of the following:
SAE 30: SAE 30 rated oils are meant for engine operating at warm to high temperatures, this category of oils is the recommended oil for small engines, which makes it a good fit for lawnmowers as the engine size on mowers is usually very small.
SAE 10W-30: 10W-30 oils can work on a range of temperatures. The variable temperature operating range makes cold starts easy but at the same time may increase the oil consumption
Synthetic SAE 5W-30: Synthetic oils are the future. These are innovative and are hardly burnt during the normal operation of the lawn mower. Synthetic oils provide the best overall protection at all temperatures and can also help with cold starts.
SAE 5W-30: Oils with the SAE 5W-30 rating are meant to be used in extremely cold climates and will help with starting and smooth functioning of the engine in low temperatures.
Fully Synthetic 15W-50: If you intend on using your lawn mower for hours on end or if your engine exerts more force throughout the lawnmowing exercise, going for a fully synthetic 15W-50 will be worth the extra money. It can function perfectly at a range of temperatures, and its fully synthetic nature makes it deposits-free.
Don’t use extra additive oils for lawn mower engines. If your region is somewhat hot and the temperatures cross 90F, then going for a 15W-50 would be the best option. This is because above 80F 10W30 can become inefficient, and using it may cause increased consumption.
On the other hand, using an SAE 30 for cold temperatures is not recommended as it can lead to hard starting.
Most lawn mowers may be using a 2-stroke engine. These engines require a fuel additive and burn a fuel-oil mixture to stay lubricated. These are fast becoming obsolete because they do not comply with the environmental regulations in some states these days. If you have one of these mowers, then looking for a 2-stroke (2-cycle) oil is the best bet.
Which Size Of Oil To Buy?
All engines are different; they take in different amounts of oil and use different technologies to work. It is best to consult the instructions manual from the manufacturer to know the right amount of oil for your lawn mower engine.
Generally, bigger engines require more engine oil than smaller ones but the decrease in oil needs is not proportional.
Engine oils have an indefinite shelf life, so if you decide to go for a bigger-sized can because it gives the best value for money, it would be a prudent decision.

Guide to Change Oil in Lawn Mower
Changing the oil on your lawn mower is easy, and the instructions for most engines are the same, be it in a car or on a lawn mower. However, it is best to consult the instructions manual so that there is no room for error.
Changing The Oil On Your Lawn Mower
Every engine needs to be warmed up before any oil flows out of it; this is because this practice warms up the oil and allows it to flow freely around.
- Once the engine is warm, place an oil tray under the drain cap of the engine.
- Unbolt the drain plug and let the old engine oil flow out. You can tilt the mower sideways or wiggle it to ensure that the old oil is completely drained.
- Wait for a few minutes to ensure complete removal.
- Place the drain screw back in and tighten it.
- Pour fresh oil into the engine oil cap, consult the manufacturer’s manual for a specific quantity of oil needed.
- Use the dipstick to check the level of oil.
- Place the cap back on, and your engine is ready to roar.
It is important that there be no dust around the engine changing bay. Dust particles can prove detrimental to an engine’s life. In addition, you should dispose of the old oil in an environment-friendly manner as used engine oil can be hazardous.
When to Change The Oil?
The decision to change the engine oil depends on the type of engine and the type of oil used. It’s best to consult the manufacturer’s instruction manual to find out the ideal number of hours after which the oil must be changed.
Riding mowers usually have the longest oil change interval, followed by push mowers. An average lawn mower needs to be flushed, and new oil needs to be put in every 25-50 hours.
If the engine is facing issues, or if you’re unsure, it is safe to change the oil after every 5-10 hours to be on the safe side. Moreover, external factors like wet grass, dense fogs, and generally humid weather also warrant an early oil replacement.
If you just got a lawn mower and it has not gone through the engine ‘break-in’ period, then changing the oil every 5 hours for the first two oil changes is recommended.
As you’ll know by now, there are different kinds of oils out there, and all carry their own unique advantages and disadvantages. Select the right one for you depending on your engine and the ambient temperature of your region.
If you’re unsure about the type of oil you want to use in your lawn mower Honda Motor Oil is the best choice for 4-stroke engines can be a great choice as it can handle most temperatures, has excellent additives and will ensure engine longevity.
