I just purchased a 2017 GX for the ability to carry more children. I simply love it. So comfortable for a truck. We took it on a 600 mile trip last week and got over 21 mpg with 6 passengers, an ice chest and duffel bags with clothes. Driving around the city I get around 17 mpg which I am happy with. I use only 91+ octane fuel and the GX only has 1000 miles on it.
