I use a combination of Power Service and two-cycle oil from WalMart in my 7.3 Ford diesel. I do this to try to get a little more lube into the "dry" ULSD fuel nowadays and to keep the fuel system clean. Diesel fuel in the US does not protect the engines as well as fuel in Europe because the allowable "wear index" in the US is higher for whatever reason. The extra lube is designed to compensate for this sad fact.

I get pretty good economy on the highway from the big 7.3 liter engine, achieving about 22 mpg in my 8000-pound pickup when not towing, and 14 mpg when towing a travel trailer at the truck's GVWR.
