Premium gas REALLY does work

The pcm senses lower octane and pulls timing to prevent detonation...just throw down the extra $2 a tank you cheap asses

I did notice a little worse gas mileage w/ the 87 though but couldn't tell on the engine. Also my new 06 GXP, I have been runnin' 87 in it & can't hear any ping or anything. I think it might be the car & what it is used to??

You are the guy i cringe at when i see him at the gas station. It is like watching a female pumping diesel in her new gas powered truck because she does not think thier is a difference.

Oh well its your car.

Thats because your computer is pulling timing to prevent the engine from pinging/detonating. You are missing out on anywhere from 10-25 hp depending on the day.
