we have two trucks, a 1988 idi, which has no hope of great milage. the other is a f250 7.3l, 2wd, it has a lame bully dog chip in it, but my dad did that before i could stop him. thanks for the start
I'm surprised at what you said about the IDI. My Crew Cab dually 92' got between 16-18 city hiway w/4.10 gears and 7400lbs. The best my stroke has done was 16 hiway. And now that it's running right and I can't stop running to 80 at every stop it's more like 12
I guess the best advice I have is leave it alone because it's "too much fun to make it run!"
Doesn't roll with anyone or tag along to be cool...
fix up the idi... get your self some WMO, Filter it out, and mix it in with #2 depending on temp conditions. Tripple or more your MPG#2
other then that, lot of guys use 2 stroke oil in the diesel... new thread started about Sulpher substitute, i just bought a bottle today and dumped it in... but with the ps antigell and some 2 stroke so who knows if my mpg will move.
loose any weight you dont need from the truck, tires to 80 psi, probably ditch the bully dog, intake & exhaust, fluid's...
do some searching...i know you will find a lot of other information
