Per the owner's manual: "Use regular unleaded gasoline rated at 87 octane or higher. However for best performance and for trailer towing, you may wish to use middle grade or premium unleaded gasoline." GM sure covers all the bases. I've had no problems using regular grade in mine. All 2000-up Northstars can use 87 octane gas. I run 93 since it can give an extra edge if you are driving the car hard like I do. But for casual driving, 87 is fine. My 2000 Deville knocks a little on 87 octane. Instead of buying premium 91 octane, I fill up and leave about three gallons to spare. Then for the remaining 3 gallons, I add E-85 ethanol. It is 105 octane and the car runs great on this mixture. You should not add any more than a 50% mixture of this to your gas as it will confuse the O2 sensor and cause a check engine light. E-85 is corrosive to a non FFV (flex fuel vehicle) but at this mixture, you will be fine and if the check engine light comes on, simply put a little more 87 octane in. For more info on E-85 go to www.e-85.com or www.alcohol4fuel.com
