there are ways to get increased fuel mileage from a diesel with its great torque - but in the end probably not worth it.
my 7.3 with mud grips on the rear end - 21mpg highway
my 12 valve - 21mpg with 35's and 3.55
my 24 valve - average 22 - made it from westcliffe colorado to dfw without stopping and 100 miles till empty, but kept it at 1800 rpm. that truck had a 3.78 rear end - i have always been curious if you could drop the rear end ratio and see an increase in fuel mileage. my college mechanics professors agree's with my idea, but says that at some point the curve will hit the other side of the pinnacle where it will require more power to push the lower gears (mind you he drives a 86 vanagon with an engine swap at 55mph and gets 25 all day)
if ur gonna drive a lot of miles and want to do it in a beast and comfortable, a 24 valve with about 60-90hp tune, exhaust and intake is your best bet imho. i work with a guy who has 350K on his 05 24valve - never had a problem

For some cruel reason, it seems like the last decade was just wiped away in the blink of an eye.

And Ive worked on and tuned 5.9s, 6.7s, 6.0s, 6.4s, 6.7 fords, 6.6 LB7 to the LMLs and LGHs. I kinda know how a diesel works..kinda.

if you feel like doing some "light" reading....
originally, rudolf diesel designed the diesel engine to run off of multiple combustable fuels - specifically peanut oil and other cheap oils - this was done so that farmers could grow their own fuel, and why there is speculation that he was killed because this would undercut the petroleum industry...
during WW2, the british used (if i remember correctly) coking oil or coconut oil which is solid at room temperature, and here's the interesting bit - they would start their trucks with normal diesel and bring them up to temperature, then the exhaust pipe was wrapped around the fuel tank holding the oil and liquify the oil. they would then switch the fuel source over to the oil and run all day on it, then switch back at the end of the day to diesel to purge the system of the oil. thus cheap inexpensive fuel.
if i only paid $.10 a gallon of coconut oil id be ecstatic at 12-15mpg.
this is why the older diesel cars (1970's to 1980's) are hard to find because they can be converted to run these types of alternative fuels - the newer trucks would crap out in a heartbeat

Originally posted by assetuncon View Postive always been curious if the 12valve would run alternatives - i knew it would run biofuel, but didnt know if it would heavy oil. with a basic heavy fuel heating system can the injectors handle a heavy oil?
