Like most things that run on an engine, a lawn mower needs oil to run.
What lawn mower oil type is best for you?
In this quick guide, we’ll answer that question. We’ll also determine what kind of weight the oil will need to be.
There are plenty of oil types out there, but not every single one is created equal and will always work on lawn mowers.
This guide will prevent you from making the wrong decision, so you can choose the right kind of oil for your lawn mower.
Like your vehicle, if you put in the wrong oil, it will not work, period. And that can lead to some costly trouble.
Can You Use Regular Motor Oil in a Lawn Mower?
The short answer is yes. However, you can’t just use any regular motor oil.
In this case, it is important to ask what kind of oil do I put in my lawn mower?
One type of motor oil you can put in is SAE 30.
This is one of the safest types of oil you can put in a small engine, including lawn mowers.
Even though SAE 30 would be your best bet, it’s always a good idea to consult the owner’s manual.
In this way, you’ll know the best type of oil for push mowers you should buy (assuming that’s the kind of lawn mower you have).
Is It OK To Put 10W30 Oil in a Lawn Mower?
Yes. As a matter of fact, it is one of the few oil types you can use in a lawn mower. It is also the best type of oil for push mowers.
10W30 oil is safe to put in a lawn mower, but what is it, really?
This specific type of oil is great when the temperatures get a bit wonky.
Suppose the temperatures are cold, but there is no snow on the ground.
In this scenario, 10W30 oil is perfect for when you need to easily start up your lawnmower in those temperatures.
If you need to fill the oil in your lawn mower, the perfect times of the year would either be in the spring or in the fall.
Your location’s climate will play a role in the kind of motor oil you choose, too.
However, you need to be really careful about what type to buy.
What Kind of Oil Do I Put in My Lawn Mower?
If you are looking for the best oil type for your lawn mower, one of these five might get the job done.
Still, you want to double-check the owner’s manual just to make sure you're using the right oil.
With that in mind, here is the list of motor oil types that are suitable for lawn mowers:
SAE 30
As mentioned, this will be your fail-safe. This oil can work in almost any lawn mower.
At the same time, if you reside in a much warmer climate, like the southern United States, this is the kind of motor oil that will work best.
SAE 10W-30
This is the kind of motor oil that will work within various temperature ranges.
This will be the perfect motor oil for those times of the year where the temperatures are a bit on the cold side.
Still, keep in mind that oil consumption will be even greater when using this oil type.
SAE 5W-30
Wondering what weight oil for lawn mowers is needed?
5W is lighter than 10W. This means the lighter 5W-30 is perfect if the temperatures are even colder.
Your lawn mower may have a hard time starting in very cold temperatures.
However, if there is no snow on the ground and plenty of grass, this oil might be what you need.
Synthetic SAE 5W-30
This will give you superior protection against all kinds of temperatures.
Hot, cold, or in between—it’s a great choice when SAE 30 is not available.
Vanguard 15W-30
This is what is recommended for commercial-style lawn cutters.
What Is the Motor Oil Capacity for Lawn Mowers?
If you own a push mower, the oil capacity will range anywhere from 15 to 18 ounces.
You must change the oil every 50 hours of use or on an annual basis (whichever comes first).
If you have a ride-on mower, the capacity will be even greater. You’ll need anywhere between 48 and 64 ounces of oil.
While you’ll have to change the oil every year, you may also need to change it out after 100 hours of use (again, whichever comes first).
Knowing what weight oil for lawn mowers will depend on the type you use.
If you are unsure, you can always consult the owner’s manual for more information.
How To Check the Oil in Your Lawn Mower?
Checking the oil in your lawn mower is the same as checking it in your vehicle.
Though it’s relatively easy, you’ll need to know how to accurately read it.
Here’s a guide on how to check the oil:
- First, you’ll need to remove the dipstick cap. Apply a moderate amount of pressure and turn the cap in a counterclockwise direction.
- If you have used the dipstick in the past, wipe it down to ensure your reading is accurate.
- Check to see if the cap’s teeth match the dipstick tube’s grooves. If they fit, reinstall the dipstick.
- Using moderate pressure, twist the dipstick cap on in a clockwise direction.
- Remove the cap once more and check out the oil levels towards the bottom part of the dipstick.
- If the oil is between the Full and Add markers, you should be good to go. Fill it up if the oil level appears to be low. A few ounces may do the trick.
- Let the oil settle before doing a re-check.
