First Oil Change

[Bostontim]

I have a 03 Xterra and changed the oil and filter using chevron 5w-30 and nissan filter at 1500 miles. Since the change the engine is driving smoother and seems to be quieter, how is this possible with one oil change and has anyone had similiar experience with chevron. Thanks

I think that you are starting to see the engine settle down due to the normal break-in period!
