noone is going to get optimal Gas mileage yet. noone has put enough miles on there cars to fully break everything in. so if someone is neting say 17 mpg. you can probly bump that to 19. when i had my 2005 GP GXP i started around 18ish and made it into he 21 mpg area after about 5k miles on it. and hiway went from 26 to about 29mpg. and then my drive from fort campbell to my home was 430 miles and i ended with 31 mpg. though i did mostly 70 interstate driving and alot of 60 mph highway driving. i have always been able to squeak out about 2-3 more mpg on ever gm vehicle i have drove.
