On page 11 of the 1st printing or page 12 of the 3rd printing of the diesel supplement found here http://www.flmowner.com/servlet/Cont...OwnerGuidePage you will see where Ford says that 45 cetane fuel is advised for best performance. Thats where I'm seeing it. The Owner's Manual is generically written for ALL Super Duty's, including those with gas engines, therefore the need for the "Diesel Supplement". "When operating in cold weather, use a minimum of 45 Cetane Diesel fuel or use Cetane improvers from a reputable manufacturer." Also a quote from another source on the subject, "The ignition quality of diesel fuel is measured by its cetane rating. The higher the cetane level the easier the fuel burns evenly and produces power. Average diesel fuel is approximately at a 40 cetane level. Large diesel trucks and diesel pickup trucks such as the Powerstroke Diesel, Duramax Diesel and Cummins Turbodiesel prefer a higher cetane rating in the 45-50 range which is considered premium diesel."
