That may be, but the engine management of Saab turbo cars since APC came in in the mid-80's, will take advantage of octane that you give it. It doesn't _need_ it; you won't damage the engine with low-octane fuel, but you _will_ get more boost (and therefore horsepower) with higher octane fuel. Been that way for Saab for about 20 years now.
