What happens if I use 10w30 instead of 5w20?

When 10w30 is used instead of 5w20, probably, only a few changes are discoverable especially when the engine is about to wear out and is old. Moreover, one of the benefits of thinner oil would be to ignite quickly. Therefore, fewer efforts are required to pump the fuel, which minimizes the fuel economy.

Is it OK to switch from 10w30 to 5w30?

You can use them interchangeably and would not likely even notice a difference at all unless it got really cold, then you’d find the 5w30 most likely cranking easier at cold start. You can absolutely run the 5w30 year around, no worries at all.

Can I switch from 5w20 to 10w30?

By using a 10w30 oil, the engine will not be damaged. In fact, it could be better for the engine because it’s a thicker oil and has a higher temperature resistance. Just make sure you allow more time for the car to warm up as a thicker oil warms up slower than a thinner weight oil.

Can I use 10w30 instead of 5w30 in snowblower?

The 10W30 and 5W30 both have different thicknesses in cold temperatures, and 10W30 is thicker than 5w30. So, it is best for vehicles running in cold climates to use the 5W30 since it is thinner than the 10w30.

What happens if you put 5w20 instead of 5w30?

Probably not. 5w20 oil is fairly light oil and is generally designed to work with newer engines. Motor oil has become part of a manufacturers program to allow engines to get higher fuel mileage. Lighter oils take less HP to pump through an engine than heavier oils.

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.
