I'm now at 750 miles and am using less than half the oil I'd expect. I'll keep you posted.
Hey blacksambo, Did this do the trick? I have a 2000 with 68000 mi on it and it started using more oil. But it does not use the same amount everytime. sometimes it uses a quart in 300mi and then the next time it will go 500 mi before I loose any oil. I want to give this a shot seeing how it is just starting to use oil.
