Default Gas mileage



My '06 GXP is fun to drive, but the gas mileage is disappointing!

If I grandpa the Grand Prix, it gets about 16-17 mpg, mostly city driving.. My wife gets about 14 mpg as a daily driver, and nothing above 4000 rpms. It did get about 25 on the hwy, driving about 75 mph, and I was pleased with that.

In comparison, my Cobra gets about 22 mpg if I grandpa it, and about 18 with several WOT romps

Really? Ive only checked 2 tanks so far...but got 19 on one and 19.5 on the last one. Thats half interstate and half city. And I drive somewhat spirited...feeling it pull so hard in second gear is just awesome. The tank i got 19 on also included getting it up to 135 mph. Also got a black one like yours...such a beautiful car

The gas mileage will improve over time. A lot of guys had low gas mileage to begin with, but I get around 20-21 mixed driving, not babying it
