Is it bad to mix oil brands?
So, my car has a very minor leak...until I am able to deal with it (changing oil pan), I would like to just keep my oil level up. However, I am not sure what oil brand the dealer used...and when I called them, they don't know either...I just know it was 5W30.
So let's say they used 5W30 of Mobile One oil...could I add a bit of 5W30 of another brand?
