2002 Grand Prix 80% OLI Mobil 1 5W-30. Fram XG3387A

Penzoil 0W-20. Oil pressures are fine until the my weak cooling system shows its face. Lost around 5 PSI most of the time. Switching to 5W-30 Mobil 1 (which i have plenty of) until i run out, then its 0W-20 in the winter and 0W-30 for summer. Amsoil next time around. two oil changes a year...

Rear springs seem to wear much faster than fronts in your typical FWD cars. (spring rates are much lower in the rear due to lack of weight) But after 10 years it seems very common. I have to say, I've heard way too many stories of people looking for a firmer ride, install AGX's and 6 months...

retrofit or bust. seeing as I drive a car, I'm already blinded by every SUV with factory HID's anyways.

New here, 2002 Grand Prix. L36 with an L67 top end (high compression, supercharged) Live in southern ontario so temperature difference between seasons can vary quite a bit. Driving habits range from easy going (longer trips, when its cold) to multiple WOT runs within a short period of time (30...
