Re: 6.9, 7.3, 6.0, 6.4, 6.7?
Hard to say. A lot depends on the rest of the truck, what you do with it and how you drive.
6.4s and 6.7s don't have a manual transmission so their MPG
6.9 and 7.3 IDI
are a little less efficient but in a good light truck with a stick and driven well, could give good MPG
. Pre-combustion engines can be deceptively efficient if you don't dog 'em too hard.
I'm a bit biased to the 7.3 with HEUI
, six-speed, 4x2
6.4s do have a manual tranny.
