My family of 5 and I just recently went on a road trip from FLA to MI. Round trio with some stops along the way there and back we did about 2500 miles. I was doing 5mph over the limit the whole way when i could. We saw about and average of between 24-26mpg on the highway getting us between 420-475 mile to a tank. Wondering if anyone else has and feed back on this from their own experience. For an SUV with 400hp and all the bells and whistles i find this to be great!
