I have had my 2003 300SD since 2008. 25 mpg average over several road trips of 400 miles or more. Mileage based on GPS start-finish trip logs. 75 mph average speed. Fuel consumed based on filling the tank to the same point each refill. A slight improvement in mpg since adjusting wastegate up to 11.3 psi WOT (FSM spec is 12.5 psi -- need to adjust again).
