SAE 30 motor oil is commonly recommended for use in a lawn mower engine, but the safest best is to use the type of oil your lawn mower manufacturer recommends. Often 10W-30 or 10W-40, the same motor oil types that are used in vehicles, can also be used in a lawn mower.
Yes! We have modified our engine oil recommendations to state that you may now use a synthetic 5W30 (100074WEB) or 10W30 oil in all temperature ranges. … Keep in mind that the use of synthetic oil does not prevent you from performing your regularly scheduled lawn mower maintenance (i.e. check oil, change oil, etc.).
Beside this, Can I use 5w30 instead of 10w30?
Yes. 5w30 and 10w30 are both 30 weight oils and the exact same thickness in your engine when it is at operating temperature. The 5w30 is better because it thickens less when cool or cold.
Likewise, Can I use 5w30 instead of SAE 30 oil?
5w-30 is fine to use. It has the same flow rate as SAE30 at normal operating temps. The way oil works is, the first number is flow rate at ambient temp.
Also, Can I use 5w30 instead of 10w30 in my lawn mower?
Yes! We have modified our engine oil recommendations to state that you may now use a synthetic 5W30 (100074WEB) or 10W30 oil in all temperature ranges. … Keep in mind that the use of synthetic oil does not prevent you from performing your regularly scheduled lawn mower maintenance (i.e. check oil, change oil, etc.).
Which oil is better 5w30 or 10w30?
5w30 is a great multigrade oil for use in low starting temperatures as well as high summer temperatures. It is also more fuel efficient since it creates less drag on the bearings and moving engine parts. 10w30 is thicker and may provide better sealing capability for older engines.

Is 5w30 the same as SAE 30?
No. SAE 30 is a single viscosity motor oil. Only multi viscosity motor oils only should be used in any car. … 5W30 is motor oil that is thinner when cold than 30 weight motor oil and thicker than 5 weight motor oil when hot.
What is equivalent to SAE 30 oil?
5w-30
What happens if you use 10w30 instead of 5w30?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
Is 5w30 or 10w30 better for winter?
The only difference between these two oils is cold flow ability: a 10w30 oil will move slower than a 5w30 oil during cold startups. … If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil. If it will only be in the engine during the summer, use 10w30.
What happens if you put 5w30 instead of 10w30?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
Is SAE 30 the same as 10W40?
The viscosity of hot oil is measured using different test parameters than when the oil is cold, so the numbers after the “W” don’t relate to the numbers in front of the “W”. The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.
What oil can I use instead of SAE 30?
After you look at the API specifications you need to check the viscosities, in this case you need to use 5w-30 or 10w-30 oil as a substitute for the SAE 30. You need to keep the second number the same as your straight SAE 30, this is the viscosity of the oil at operating temperature.
Can I use 5w20 in my lawn mower?
You could. But motor oil in a lawnmower engine takes a tremendous beating. A lighter oil like 5w20 will lose viscosity faster than 10w30. Only if you plan on using the lawnmower in the snow.
Is there a difference between lawn mower oil and car oil?
They use the same oil as automobiles, but owners should check manuals because these small engines are sensitive to additives and alternatives. … Typically, these engines use straight SAE 30 weight oil or multi-viscosity 10W-30 oil, both common auto engine oils.
Is it OK to use 10W30 instead of SAE 30?
Yes, you can make use 10W30 engine oil instead of the SAE30 in your Lawn Mower. … Older engines can use the SAE30, while the 10W30 is for modern engines. Again, the SAE30 is better for warmer temperatures while the 10W30 is suitable for varying temperature ranges and also works well in cold weather.
Is 4 Stroke Oil same as car oil?
It’s fair to say most four-stroke engines use oil in the same way, whether it’s a car or truck or motorcycle. The basic idea is that oil does several things. … Oil does a few other things, it prevents internal corrosion and it’s designed to keep any contaminants in suspension until the next oil change.
Can you put 10W 30 in a 5W 20 engine?
There should be no issues at all running a 5w30 or a 10w30 oil in a 5w20 spec’d vehicle.
