What Our Members Are Saying about the Real Gas Mileage of the Mercury Montego

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
 

What Our Members Are Saying about the Real Gas Mileage of the Buick Rainier

Buick Rainier Real Gas Mileage: Cons
YearBody/PowertrainComment
2005 4dr SUV 300-horsepower 5.3L V8
4-speed automatic AWD		 12 mpg see full Buick Rainier review
2004 4dr SUV 290-horsepower 5.3L V8
4-speed automatic AWD		 An AWD V8 body on frame SUV/truck like the Rainier will be a gas pig. Mid to high teens are all you should expect. The benefit of poor gas mileage is strong towing performance. see full Buick Rainier review
