ive got 3700 mi on my 5dr premium cvt. i average between 26 and 30 a tank and that is with a remote start warming it up for 10 min before i drive it. on the highway doing 55-65 i can get the 36 with cruise control but i do most of my driving around 75 and i still average 30mpg overall im happy with that. but i think when the weather gets warmer it will do better. so the lowest ive seen on an over all tank is 26mpg.
