What Our Members Are Saying about the Real Gas Mileage of the 2005 Infiniti G

2005 Infiniti G Real Gas Mileage: Cons
YearBody/PowertrainComment
2006 2dr Coupe 280-horsepower 3.5L V6
5-speed shiftable automatic RWD
The fuel economy and the premium fuel requirement are somewhat disappointing. I averaged generally about 16mpg per tank when I lived and worked in a large city. Now that I live and commute to school out in the sticks, I am seeing around 22mpg with the cruise control locked at 55-60 during my 32 mile commute. see full Infiniti G review

Ive gotten as low as 13mpg, but I drive the car hard and I mean hard. see full Infiniti G review

avg 19.5 mpg. Yeah I could do better if I never got on the gas, but then what would be the point of owning a G? see full Infiniti G review
