5w20 is an engine oil type characterized by its winter rating of 5 and an oil weight of 20 in warmer conditions. It is less viscous compared to 5w30. 5w30 has the same viscosity rating of 5 during winter but an oil weight of 30 during hotter conditions hence it is thicker.

Is it OK to use 5w30 instead of 5w20?

In general, it is not recommended that you use 5w30 oil (or any other oil weight) in place of 5w20 oil, as the slightest difference in viscosity can potentially damage your engine.
