My user's manual for says 90 for the base model, and 92 for the SE and Viggen. On the inside of my gas cap door is a little sticker that gives the required levels as well. Apparently the Saab engine's computer system can adapt to varying octane levels in fuel, so you won't necessarily damage your engine with the 87 octane fuel, but it won't run as well (with respect to power and pickup) or as efficiently. -- Viktor Haag Senior Technical Writer, RIM '79 99, '89 9000T, '00 9-3 SE My opinions are my own, only.
