From a 17mpg average Chevy truck to NEVER getting less than 29mpg city, need I say more? Well okay, how about 37mpg on a freeway run. I have only got 13000 miles on the vehicle, and can imagine the fuel economy will improve still more. see full Kia Rio 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 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
