I think I need to get some of that canadian diesel down here in Texas...
he fuel in the USA has been government screwed to death Ultra low sulfur has way less energy per unit than low sulfur did and even less than High sulfur. These engines can do magical things with mileage for sure. during Katrina we were hauling fema trailers and getting high sulfur (legally btw) mileage on our back hauls empty was GREAT like 6 to 10% better but that fuel is WAY different.
