Aww, c'mon. You know as well as I do that the 3,000 mile oil change is bunk. It's just cheap insurance, so even people like you and me go with it. 😀Originally posted by: Zenmervolt
And as long as you have no intent of keeping the car past a maximum of 150,000 miles.Originally posted by: tnitsuj
7,500 miles on good non-synthetic is pefectly possible as long as you aren't burning oil and you are doing mostly highway.

Remember, there are 25,000 mile/1 year oils. You must change your oil filter every 6 months, and you really should be doing oil analysis, but that is still a fact.
Also remember that the 7500 mile figure is for light duty service. "Normal" is normally 5000 and "Severe" is 3750. Many, if not most, automobiles qualify for Severe service.
The normal oil change interval in Europe is ~9000 miles, IIRC. The 3,000 mile oil change stemmed from poor oil quality and less efficient engines in the past, but it is currently just marketing.
