Running empty, driving 55mph(pine cone glued to acceleretor pedal and me barefoot) I made 67 miles past dte 0. No vent kit yet. I always seem to have the extra time to fill all the way up. It took 39. 785 gallons and I had 821 miles. To those folks who will claim BS I say slow down, way down ya'll are the reason fuel costs so much. If we were all more conservative with our driving we would use less fuel. This is the first diesel I have owned and it is 5 times the truck I used to have. It is heavier, more powerful, has two drive axles, can carry more, has more gears, more interior room, and gets better mileage than the 300I6 I used to own could have ever imagined.
S L O W D O W N!!!!!! Ya'll remember the slogan "55 saves lives" ?
IT SAVES FUEL TOO!!
