Thus far, I have averaged 23 and 26 mpg, both times have had roughly a 70 mile highway trip out of 200 miles. Overall, I find this to be acceptable. see full Pontiac Grand Prix review
2004 Pontiac Grand Prix Real Gas Mileage: Cons
YearBody/PowertrainComment
2005 4dr Sedan 303-horsepower 5.3L V8
4-speed shiftable automatic FWD
17-19 mpg in the city. 25 If I drive on the intersate. 30 is possible at 60mph. Most of my driving is in the city. The beautiful v8 makes it impossible to stay out of the gas, but it can run on REG fuel. see full Pontiac Grand Prix review
