My Ride: 2003 BMW 325i
E46 Gas

Only Run Premium, BMW's run hot and have a high fuse rate, Premium is the best for your car and would always run Premium gas. BMW's can get knocking and Pinging and as your owners manual says "anything below 91 octane after a while can cause knocking and pinging and can damage the oxygen censors" BMW's are the best but are expensive. You bought a BMW if you cant afford to maintain it sell it. needs premium.
