I've been wondering this for a while, but I didn't want to enter that Australian-argument thread, so here's a Saab-only question: What would happen if I ran my 2002 9-5 Aero on regular unleaded, instead of premium? My wife thinks it will save us money. I'm concerned it could cause damage to the engine, or at the very least cause enough power drop that you'd lose the cost savings. Then let's extend the question to her car: she has a 1984 Porsche 911. It's supposed to have premium, and it doesn't have the fancy electronics that my 9-5 has. What happens if she feeds HER car lower-octane fuel? Thanks! Gary
