Asked by Dec 29, 2012 at 11:22 PM about the 2002 Pontiac Grand Prix GTP Coupe

Question type: General

My nephew just bought a 2002 Pontiac Grand Prix GTP Coupe. It has the supercharged 3.8L V6. The car didn't
come with an Owners Manual. He's wondering if he needs to put premium gasoline in it. Thanks in advance.   -Jim

This car MUST HAVE PREMIUM. Also emphasize, if premium gasoline is not put in this car you WILL blow up the engine. There is not enough octane in the regular gas, when the car is given too much throttle when using lower octane gasoline the mixture becomes too lean and it WILL blow a hole right through the top of the piston on the car. So yes, you need premium.

Thank you Clayton, I'll let him know. -Jim

That's hog wash about blowing up the engine. I have a 2002 Super charged GTP that I bought new. As recommended by GM I ran premium fuel for the first 65,000 miles then switched to middle grade with out any problem or hicup. Never noticed any loss of power or performance. The car now has over 100,000 plus miles on it of hard L.A.freeway commute. Just use quality gas and never regular grade out of respect to the car.
