those who do their own car work

For what its worth I had the oil tested after first oil change I did on the car (at 60-65k) and the test came back good. It prob also helps that I dont drive the piss out of it.

Now when I had the Z06 GM said it should go 7500 between changed with mobil 1, and the onboard computer would tell me it was time to change in 3-3.5k, but that car was auto-xed almost every weekend

Cool deal ... the onboard oil change indicators mostly use load as a modifier for when to change it (ie. MAP / MAF, Inj. Duty, etc.). My M3 will vary with how I drive it.

I figure if the bottom end drops out I have a good reason to go get a CTS-V :-)
