62!! You and I are not the sameWhat speed are you going?
Do you have the "eco" button turned on?
jedi has noticed that 62 mph is the sweet spot. Set the cruise at that and it's all good. Get behind a semi at 55 to 58 and it's even better.
From the limited Google searches jedi has done its due to wind resistance and this van being a box. Higher speeds causes too much drag and thus burns more gas.
