Fuel Question for 9-3

The 9-3 will run on regular (e.g. 87 octane) gasoline, but there will be a substantial performance pentalty as compared to using higher octane blends. This is because the 9-3's turbo engine can achieve higher boost pressures with higher octane gas before predetonation occurs.

Actually, per the SAAB owners manual in the 2003 Linear you can use regular (87) but 89 is preferred. In the higher output Arcs and Vectors (aka Aero) you should use 91+, but can get away with 89 in a pinch.
