I don't remember what my 95 900 had for a gas reserve...but for those who do know such details, it would help for you to say what year 900 you are asking about, as the car changed greatly between the early 90s and later... ===== What year 900 is very important as the gas tanks changed over the years. The specifications for a 1979 are different than a 1989 or a 2nd generation 900 (1994-on). In general, figure about a gallon remaining when the low fuel level light comes on. It may be more, but it is not the same for all 900s.
Yes, ethanol powered vehicles are also known as "flex vehicles". The Saab 9-3, which is created by Saab is powered by ethanol instead of gas.
The fuel filter on a Saab 9-5 is located above the gas tank in the rear of the vehicle. The fuel filter has a line leading to the EFI (Electronic Fuel Injector) in the engine, a vapor line for the gas tank, and a fuel line from the gas tank.
drop the gas tank
Yes, the computer adjusts the ignition to compensate for lower octane. Less performance, but no harm
