2000 Bonneville SSEI
ok i have a question on what type of fuel i should use. When i had a few problems with the car and it was under warranty the dealership said that i should only use premium is this true?
Yes, use 91 at LEAST. It will benefit your car in the log run. Don't look at it as spending more money at the pump, because it'* not much more than regular. There have been several topics on this recently, try searching for more info.

Between regular and premium its a $2-3 difference fill the tank, I have a RaceWay Card thats gives me %10 back on my purchases at Raceway, I only use that card for gas. so i get that $2-3 back
I don't think it was determined that Tim'* failure was fuel related. Whether or not it was, there'* a few of us that have experienced the difference first-hand in either decreased performance, decreased fuel mileage, or actual damage.
