A shameless ripoff from the ford trucks forum on the 7.3 liter diesel.
Diesel Fuel Additive road test results
Just thoughts I'd share the info....
The solar system lined up just perfectly where I had three identical 600 mile round trip runs from Tucson to El Paso with no load or trailer, so I decided to try out two DFAs. I fueled up at the same stations each time.
The first trip I ran straight pump fuel with no DFA of any kind.
75-80mph cruise speed (Tucson-El Paso) net 15.1 mpg
60-65 mph cruise speed (El Paso-Tucson) net 18.8 mpg
Second trip with Shell Rotella DFA.
75-80 mph cruise speed (Tucson-El Paso) net 15.5 mpg
60-65 mph cruise speed (El Paso-Tucson) net 19.8 mpg
Third trip with Diesel Kleen (grey bottle)
85-93 mph cruise speed (Tucson-El Paso) net 16.0 mpg
60-65 mph cruise speed (El Paso-Tucson) net 21.0 mpg
The last trip was pretty quick going out, I shouldn't have been driving so fast, it was just that the truck seemed to be running very well that it was hard to stay out of the throttle. There was a VERY strong headwind most of the way to El Paso, so I had to keep my foot in it to keep up the speed. Then the wind would die down for a bit and I would peek at my speed and it was stuck at 93 mph. I guess that's the fastest the truck will go.
Anyway, I think I'm sold on the Diesel Kleen product. ($10.99 per 96 oz at Flying J Truck Stop) About 3 mpg better fuel economy, easier starts, smoother engine and more power. Pretty cool stuff!

Dunno if this diesel kleen stuff does anything about gelling.
