How many mpg's do you get with your 5.9? City? Highway?

**** dude that's bottom of the barrel
my truck, which is a 12 valve 5.9(just know it's better, don't ask why) gets 20 or so combined...a strait freeway run at 65 would prolly get me upper 20's
oh snap we're in the diesel section aren't we
damnnn, glad to hear it's better mileage than I thought Do they make the 5.9 in a 24v and also, what is the difference between a 12 valve and 24 valve..other than double the valves
