Managed 43.55 on the dealer filled tank . Hopefully the DISPLAY overall gas mileage will get closer to the CALCULATED . A/C used around 1/3 and 2 of us for whole tank . Start of 2nd fill is at 44.1 M.P.G. . This is summer blend (?) Top Tier SUNOCO Ultratech 89 w/E5 @ 1 click . The tank is 11.9 gallons .
Nice, I had a 2010 GLS automatic and managed to get 38-40 mpg in a 1200 mile trip
