There are a variety of different motor oils on the market, and it can be confusing trying to figure out which one to use. In this article, we will explore whether or not you can use 5w20 instead of 10w30 in your lawn mower. 

Can I use 5w20 instead of 10w30 in my lawn mower?

Yes. You could. Briggs & Stratton, Honda, Toro, and Kohler recommend that engines in their devices use 10W-30/SAE 30 or 5W-20/5W-30 synthetic oil. Until that time, you should use 10W-30/SAE 30 or 5W-20/5W-30 seems new. The ideal viscosity is 5W-30.

5w20 VS 10w30 – Which One Is Better?

First, let’s take a look at the difference between these two motor oils. 5w20 is a thinner oil that is designed for use in cars that operate in cold weather climates. It’s also used in other engines such as snowmobiles. The “20” in 5w20 means that it only has 20 weight percent of the oil in it, and the rest is an anti-foaming agent. 10w30 is a thicker oil that is used in engines that operate in cooler temperatures.

10w30 oil has 30 weight percent of the oil in it and the rest is an anti-foaming agent. Let’s now take a look at the pros and cons of using 5w20 instead of 10w30 in your lawn mower.

The main advantage of using 5w-20 motor oil is that it costs less.

Conversely, the main disadvantage of using 5w-20 motor oil is that it does not provide the best protection for your lawn mower engine.

With this in mind, you would have to decide whether or not the cost savings outweighs the benefits of using 5w-20 oil. There are also other lower-quality oils, such as 5W-30, that are sometimes sold for lawn mowers. While these oils may provide similar protection to 10w-30 oil, they cannot be used in your lawn mower without risking damage to the engine.
