FAQ:

Q: What kind of oil does a 4 stroke engine use?

A: 4 stroke oil is used in 4 stroke engines where the oil and gasoline are separate. A car engine for instance is a 4 stroke engine. 2 stroke oil references gasoline engines where the oil and gas are mixed. Examples include chainsaws, lawnboy lawn mowers and other small engines.

Q: What does 10W30 grade motor oil mean?

A: In regard to multigrade oils, the first number in the code, such as 10W in SAE 10W-30, means that the oil can still be pumped by the engine at a temperature as low as a single grade 10W oil. A 5W, like in SAE 5W-30, can be pumped at an even lower temperature, and a 0W, like in SAE 0W-30, will pump at the lowest tested temperatures.

Q: Can I use 10W30 instead of 5W30?

A: To conclude, we must say, you can use 10w30 instead of 5w30, but you have to be very careful of some things that we have shared before. Well, if you have 5w30, then you must use it for your new engine. But if you don’t have it then you can also use 10w30 motor oil. Though it works better for older engines, you can also use it as an alternative.

Q: Can I use 10W40 instead of 10W30?

A: You should not put 10W40 instead of 10W30. It would be best if you stick to the exact engine oil mentioned in your owner manual. Different engine oils show various performances. Also, it works differently for every other engine. What will happen if you put 10W40 instead of 10W30?
