Got my 06 H3 in august got my best hwy mpg of 17.5
all highway cruise set at 70 mph with less than 1000 miles on odometer, now with about 16800 my best mpg is 15 on hwy w/cruise set at seventy so after break in mine got a little worse
all this with extra weight of winch, roof rack, high lift and pull pall. not sure what changed for less mpg but still get 15 on 20.1 gallons when light comes on so i,m satisfied although it would be nice to see city mileage during hwy driving
