I think if you don't get the knocking and you don't track your car. that will be more then good. I have a Maxima that I drive hard all the time I change out the oil every 5000km with cheep old hi milaege prestone. And I got over 250000km on the car with no engine issues.People that are not tracking their car on a regular bases I think put too much time and effort into oils.
