Mercury Montego Real Gas Mileage: Pros
YearBody/PowertrainComment
2007 4dr Sedan 203-horsepower 3.0L V6
6-speed automatic FWD		 It is great for such a big car. 30 mpg is pretty easy for highway cruising, and mixing driving will do 24-25. see full Mercury Montego review
2005 4dr Sedan 203-horsepower 3.0L V6
6-speed automatic FWD		 A large car that gets over 20 MPG in city driving is great. The 29 MPG highway rating is nice, but the car is mainly used as a grocery getter / errand runner. see full Mercury Montego review
2005 4dr Sedan 203-horsepower 3.0L V6
6-speed automatic FWD		 Surprisingly good fuel mileage. 24 city/31 Hwy. see full Mercury Montego review

2005 4dr Sedan 239-horsepower 4.6L V8
4-speed automatic RWD		 The V-8 is thirsty for city driving. The extra power would be nice for highway & mountain driving, though. see full Mercury Grand Marquis review
