I have however had to use the lower octane gas for my '91 9000T...don't do it. i live in a fairly hilly area in western PA. terrible gas mileage, the car sounds as if she's struggling etc. that's just my 9000T but you didn't ask for that info. let us know if you see a difference should you try a lower grade with your baby.
