Last time I really did a mileage check was on an '79 B100, carbureted 5.2L SWB cargo on a 10,000 KM trip to Victoria (B.C.), and after much experimenting with jets and rods, the best I could get was 18 MPG (Imperial gallons) at around 110KM/Hr. The best jet combination came from a "Lean Burn" carburetor. Just returned from a 6000KM trip to Newfoundland in an '89 B150 5.2 L and it cost about $20-22 per hour to operate or about 5L /100 KM. This one is dual fuel (propane) and that usually yields 4L / 100 city or 5L / 100 HWY. Propane in Toronto is currently .40/L
