Can You Use Synthetic Oil in Lawn Mowers?

Do you want to keep your lawn looking like a green carpet? We’ve all been there, but we never want to be there again. It can be so frustrating when we’re trying to get our lawn just right and the engine in our mower starts sputtering on us.

Maybe it’s time to invest in a new mower, but maybe you don’t have the money for it yet. You may be considering using synthetic oil in your current mower. Don’t do it! Synthetic oil will destroy your engine. Here are some important reasons why you should not use synthetic oil in your lawn mower

What is synthetic oil?

Synthetic oil is the oil used in many cars and trucks today. It’s often called “engine oil” in the auto industry. Engine oil is only to lubricate the engine of a car or truck, but some of it will also help a car or truck move in a smooth and straight line.

However, if synthetic oil is being used in your lawn mower, it will be used to lubricate your engine. This can wreak havoc on your engine. The chemicals in synthetic oil can ruin the oil in your engine and work their way into the bearings in your engine.

This can eventually lead to the engine being ruined or starting to seize up. What are the health effects of using synthetic oil? Synthetic oil is highly flammable, so the flammable chemicals that are added to it can ignite, causing a fire.

Is it safe to use synthetic oil in lawn mowers?

Even though many mowers do come with the type of synthetic oil that allows you to use it, you must have the permission of your lawn mower manufacturer to use it. Synthetic oil is classified as synthetic and as a gasoline additive.

This means that you can never run your engine on synthetic oil. Your engine will only run efficiently on the type of oil that is designed specifically for your lawn mower, and that oil is not an approved synthetic oil.

Does it make the engine run better? No. It actually makes it worse. The engine that runs on synthetic oil is only designed for a petroleum-based engine. You can’t use an engine that is made of something else. What is synthetic oil used for?

Why you should not use synthetic oil for your lawn mower

This probably sounds crazy, but this is one of the biggest common mistakes lawn care professionals make in their businesses. They put synthetic oil in lawn mowers, but many never ever replace the engine in their mowers! If your lawn mower is not performing up to par, it probably has synthetic oil in it.

That means when your lawn mower starts to sputter on you, you’ll likely have no idea why. You may have to replace the engine in the mower! The good news is you can avoid this by not using synthetic oil! Synthetic oil won’t last for the life of your mower. A lawn mower engine typically lasts 10-15 years, but replacing the engine in a lawn mower often costs a few thousand dollars.

What does synthetic oil do to your engine?

Synthetic oil doesn’t work like regular oil does. The inside of a typical engine is filled with tiny pockets of oil, all of which contain highly oxygenated and highly lubricating properties. Unfortunately, these pockets of oil aren’t affected by temperature changes or high loads of pressure.

Because they’re all used up by the engine as they come into contact with it, these pockets of oil are not replenished when they’re not being used. When a lawn mower uses synthetic oil, the oil that is being lubricated is replaced in the engine by a very low-quality replacement oil.

The “synthetic” oil won’t have the same properties that regular oil has and can end up causing more problems than it solves.
