Agree with fmarshall. I remember reading, what I remember as an SAE submission, years ago about BMW's experiences in developing the algorithm for their oil change indicator software.

I'd love to find it again to quote it exactly, but memory serves me that they found that even in the most extreme conditions they found a minimum 9000km (5500 mi) oil change interval. That was with synthetic, mind you, but was in extremes that sf mentions would only drive the interval below 6000 miles too. So fairly consistent in that respect.
