My car is showing on the fuel consumption that I am getting about 57 mpg on both the trip a and fuel economy screen on the dashboard. Note I have not reset the trip Meyers since collecting the car, so expect them to match.

However, the OnStar app shows the economy to be 65 mpg although the trip a reading on the app matches the car.

Anyone else had this?
