Well, I will chime in here.....friend has an Acadia......complains about the mileage......19mpg, sometimes less......jumps on me, being a GM tech.......
Well, we have to take a 200 mile round trip to pick up his son.....I suggested we fill her up and reset the trip odometer to zero......and I drive, normally, not like his lead foot wife...
We get back home and fill her up again, at the same pump, the same way.....divided milage on the trip odometer by gallons on second fillup.......24.5 mpg.....
I said to him, this vehicle is made for the highway, not bumper to bumper traffic and the hills of this city, especially with his wife driving....and the vehicle is usually full of kids and whatever she is hauling......told him the EPA should hire his wife and kids to test their vehicles.....
