What oil do I put in my riding lawn mower?



SAE 30 – Warmer temperatures, most common oil for small engines. SAE 10W-30 – Varying temperature range, this grade of oil improves cold-weather starting, but may increase oil consumption. Synthetic SAE 5W-30 – Best protection at all temperatures as well as improved starting with less oil consumption.

What kind of oil does my riding mower use?

Lawn Mower Oil Types



10W30 is a common motor oil grade suitable for many lawn mowers. Your owner’s manual will tell you the exact grade required, but in almost all cases 10W30 is the right stuff for a four-stroke engines. Any brand of oil that’s suitable for cars or trucks will work fine in your mower.

Can I use 5w30 instead of SAE 30 in my lawn mower?





In most cases with a lawn mower engine, you’ll be fine using SAE 30 vs 5w30. But, there are three things you should take into consideration though. First, how new is your mower? Some newer lawn mowers have been designed with multi-grade oil in mind, and the manufacturer may recommend using 5w30 over SAE 30.

Is SAE 30 same as 10W30?

10w30 is thinner than SAE 30. The “30” means that it has the same viscosity as the other when the engine is hot. However, since it is thinner, it will never become as thick as SAE 30 when it gets cold. 10w30 has a viscosity of 10w which means it will start moving and protecting engine parts at a colder temperature.

What is the best oil to use in a lawn mower?

Therefore the first three letters you need to know are SAE, the acronym of the Society of Automotive Engineers. This society is responsible for establishing a classification system based solely on oil viscosity.



Is SAE 5W 30 oil the same as SAE 30?

Both oils have a “30” hot viscosity rating. This means SAE 5W-30 oil has the same flow rate as SAE 30 at operating temp. So, technically it’s fine to use SAE 5W-30 oil in place of SAE 30.

What happens if you put car oil in a lawn mower?

A Few Final Words



In summary, the answer to the question, “Can you use car oil in a lawn mower?” depends on the engine of your lawn mower. Car oil ruins two-stroke engines but lubricates four-stroke engines just fine. If it is a premium oil such as SAE 30 or 10W-30 oil you can use car oil in your four-stroke mower.

How do you tell if a lawn mower is 2 stroke or 4 stroke?

The easiest way to check what type of engine a lawnmower has is by checking its fuel tank. If there is only one port for oil and gas, then it’s a 2-stroke engine, and if there are two ports, then it’s a 4-stroke engine.
