I own an '04 GTP. A trusted mechanic friend told me that there should be a decal inside the panel door to the gas tank that indicates the car requires premium gas. Mine does not have this. I've continued to use premium gas anyway but with the astronomical cost of fuel I think I'm about to see if he's right.
Yes, you must use premium fuel due to the higher compression of the engine from having a supercharger. A decal on the panel door of the gas tank could have been taken off or fallen off. Do not rely on this. Your owner's manuel will tell you to use premium (91 octane or higher) in your vehicle. If you think the price of gas is too high in order to do so, you should not own this type of car.
While the above is good advice (not to trust the sticker on the fuel door) it is not 100% correct. I own a 2004 GTP Comp G and the 2004 model and above does not REQUIRE premium fuel, it says so right in the owners manual. If you use 87 oct fuel and you hear eninge knock I would switch to higher oct fuel. This is not true for 97-03 GTP's they require premium fel.
I put 89 in my 04 the other day because that's all they had. Ran fine.... I'm sure it wasn't making full power but no engine knock or any other problems came up.
What else can I help you with?

Where are the oxygen sensors on a 1997 Grand Prix GT?
The front O2 Sensor is on the rear exhuast manifold. If you take off the heat shield, it will be near the #6 spark plug and the tranny dipstick. there is a wire sticking out from the top. The rear O2 sensor is underneath the car, after the catalitic converter. On GTPs, it is standing straight up on the "u-bend". Im pretty sure GTs are the same, since they both have basically the same engine (3800 Series II).
Where is the power steering reservoir for 1999 grand prix gtp?
The power steering reservoir on all Grand Prix GTs and GTPs 1997-2003 is located at the front of the engine (passenger side of the vehicle, as the engine is transverse mounted) near the firewall. Looking at the engine from the passenger side, identify the alternator, and approximately 3 inches directly underneath the alternator is the power steering reservoir cap. don't believe you can physically see the cap on the reservoir unless you remove the coolant recovery reservoir, so it will require a bit of feeling around the first time, but once you find it the first time, you won't ever forget! Hope this helps!
Where is the PCV valve located on a 2001 grand prix gtp supercharger?
For all GTPs 1997-2003, the first step is to remove the cosmetic supercharger cover. At the rear of the motor, on the driver's side of the vehicle, there is a small plate etched with "PCV." Use a small socket and ratcher to unscrew the two bolts, and the PCV valve will be exposed. The PCV valve may stick, so you may need needlenose pliers. Remove the valve, and do not lose the corresponding spring. Simply put the new valve with the spring in and reinstall. Hope this helps!
