In fact from my owners manual
Quote
If you have a 3800 Supercharged engine (VIN Code 1), use premium unleaded gasoline rated at 91 octane or higher. With the 3800 Supercharged engine, in an emergency, you may be able to use a lower octane -- as low as 87 -- if heavy knocking does not occur. If you are using 91 or higher octane unleaded gasoline and you still hear heavy knocking, your engine needs service.

"I cant remember what the "pinging" is, but if i remember right, it wont hurt your car."

Since "pinging" is in fact the cylinder walls vibrating from detonation, I strongly disagree.

If it says use premium, use premium. Pinging, even a little, is death for supercharged engines.

ya i dont get very impresive fuel milage from my car (twin to yours) aswell....however i know that its only because i have a VERY heavy foot!!

P.*. I use primium only (like it says on the dash under the fuel gauge!

x4 Says in my manual to use premium as well as the fuel door.

On 95 SLE'* factory supercharged the fuel door states "Use Unleaded Fuel Only" and on the dash it just says Unleaded Fuel Only.

Owner'* manual should read the same as any 1995 SSEi owner manual.
