I own a 2014 F150 4x4 SUPERCREW-145 XLT, XTR with the full tow package and 3.73 axle. When I am not towing I am averaging 12l per 100 kms or 23.5 MPG. This is not bad and I find all I really need to do is manage the transmission shift points to keep it in 6th gear as much as possible. I am very pleased with my truck…
