Can You Use Car Oil in a Lawn Mower?

If you are thinking that if oil of regular car can be used in a lawn mower, then the answer is yes, you may use car oil in a lawn mower sometimes.

Oil is something that helps the engine to function. Just like cars, without oil, a lawn mower won’t run.

Changing the oil is a basic maintenance task that should be performed regularly.

Why Should You Use Car Oil In A Lawn Mower

The company’s that make these lawn mowers usually make oil for the mowers.

But I find them a bit expensive. You can simply use the oil you have already purchased for your car.

Before buying oil for your lawn mower, read the company manual.

They must have been suggesting the best oil for you. But you can work with SAE30 motor oil.

I usually prefer using the oil suggested by the company. But last month I was out of stock and my lawn needed an urgent mowing.

And was really worried about what to do. Then I did some research on the internet and found a good solution.

I found out that I can use car oil in a lawn mower. But I made sure the oil grade was same.

If you go through my post, you will get to know more about oil for your lawn mower.

At the end of this post, I will give you some tips to keep your lawn mower running all through the year.

Types of Oil for Lawn Mower

For your lawn mower the company has already chosen the best oil. And there is so much oil in the market to use in your mower.

Yet you can sometimes use car oil in a lawn mower.

But before that, you should know that you need to use high-priced oil for your mower. A great type of oil to use in your mower is SAE30 motor oil.

When to Change Oil for My Lawn Mower

You may be worried to think when or how often to change the oil of your lawn mower.

You can simply find the time duration for your mower in the user manual provided by the mower company.

But I would say from my experience that you have to change the oil as often as you change the oil of your car.

Some people may think I have installed the oil 4 months ago and haven’t used the mower since then.

I do not have to change it now after 4 months. But the answer is No. Because this idea may ruin the performance of your mower.

You have to change the oil even if you have not used the mower for a single time or may have used it for a few minutes.

The oil loses its character while staying in the engine for a long time even if it has not been used. 

The oil capacity of a walk-behind mower is 15oz or 18oz.

So the ideal option would be changing the oil after every 50 hours you use the mower or annually in every 6 months if your mower was sitting idle.

Go for the one whichever comes first. And if you are out of stock then you can use car oil in a lawn mower. Just make sure the oil grade is similar to the company’s one.

For a riding lawn mower, the oil capacity is 48oz or 64oz.

It will be best to change the oil after every 100 hours you use the mower or annually in every 6 months if your mower is sitting idle. Go for the one whichever comes first. 

How do I check the Oil Level

It is always good to check the oil level after every 2-3 months.

You can check the oil level of your lawnmower simply by following these steps:

  1. Start the mower before 2 to 3 minutes before changing the oil. It will make the oil less thick and will help out the oil to flow easily.
  2. Remove the Dipstick cap
  3. Apply some pressure and twist counter clockwise.
  4. See for the teeth on the cap match the groves on the dipstick tube
  5. Apply some pressure and twist clockwise to reinstall the dipstick cap
  6. Remove the cap again and see the oil level toward the dipstick blade.
