I usually go about every 5k with synthetic oil. If you're putting the natural stuff in, 3k is about the limit, for normal driving. If all you do highway stuff, then hell, you could probably go 6-7k without problem.
It's the fluctuating RPM's that are hard on cars.
Oh god, I just laughed over the fact that I said "HARD ON."
