We got the V6 for the supposed fuel-economy benefits. The car rarely breaks 20mpg (with a one-time high of 23), and last in-town average is about 14 mpg. see full Cadillac SRX review

Mileage is acceptable but nothing more. Around 20 MPG on the highway and 15-16 around town. see full Cadillac SRX review

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

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

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

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
