2010 0 171-horsepower 2.5L I4
6-speed automatic FWD		 getting 31 mpg highway see full Mercury Mariner review
2009 4dr SUV 171-horsepower 2.5L I4
6-speed automatic FWD		 Has been very good and getting better see full Mercury Mariner review
2009 4dr SUV 240-horsepower 3.0L V6
6-speed automatic FWD		 Coming from a Trailblazer, we like the average of 21-22 MPG in mixed driving, as were used to about 17 MPG. Fuel economy climbs toward the rated 26 MPG the more highway driving we do. see full Mercury Mariner review
2007 4dr SUV 200-horsepower 3.0L V6
4-speed automatic AWD		 For the first almost three years after we got the car, it gave 21+ mpg in town & 24+ mpg on the road. see full Mercury Mariner review
2005 4dr SUV 153-horsepower 2.3L I4
4-speed automatic AWD		 For an SUV with a 4cyl and 4wd I get avg of 22 MPG mixed city and highway. I usually get 23-26 on freeway only. This is good. see full Mercury Mariner review
Mercury Mariner Real Gas Mileage: Cons
YearBody/PowertrainComment
2007 4dr SUV 200-horsepower 3.0L V6
4-speed automatic AWD		 For some reason when new Michelin All Terrain tires with Nitrogen air replaced the Champions from the factory, it plummeted to 17 & 20 mpg. No explanation from Michelin, Costco or Ford/Mercury - they have no idea why. see full Mercury Mariner review
