Infiniti FX Real Gas Mileage: Cons
YearBody/PowertrainComment
2008 4dr SUV 275-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Averaging 18 mpg. Not horrible, but not great either. With gas prices having doubled since the start of my lease, I try and minimize driving outside my commute and necessary errands. see full Infiniti FX review
2004 4dr SUV 315-horsepower 4.5L V8
5-speed shiftable automatic AWD		 18 miles per gallon on average. see full Infiniti FX review
