I think so too, it does however seem to use more when doing a lot of higher rpm highway type driving with getting on it once in a while. Still no obvious smoke, but definitely more oil burning.

Yea that was my whole reasoning for buying the car. About 100 hp more than a stock c6z with an engine that should be reliable / was made by GM. Apparently I should have just bought a zr1 lol :(
