mpg of a diesel burb

What would the MPG be for a 73-91 style burb w/ 6.2, 700, and 3.08 gears?

parents had an 82 with the 6.2 2wd when i was growing up and it got about 27.

cool beans! Many thanks bud! I may consider a 2wd but 4x4 is handy sometimes just because.

i think 3:08 gears is a bit tall with the th700 unless you want to cruise at 80mph all the time..

i don't have a diesel (would love to but those engines go for 2500-3000 $ here !!!) some says the diesel gives the best economy at 1800 rpm..might have that in mind

voted 20 because that seems to be the consensus and with the 700 i wouldn't be suprised if you got more on the highway.

well I know that 3.08's are a little on the high side, but the biggest tire I would run on this burb would be a 31". I may even run 235/75/15's (29"). So.... I just want this to be a comfy family rig that gets groceries and goes on trips and gets great milage

That combo would slower than the second coming, but on the freeway it should pull down 22-24 mpg @65ish

Yea, I agree fully. My 6.2 3/4ton sub is no speed demon, even with th400 & 4.10 gears. It pulls hard...just not in a hurry.16-18mpg if I drive carefull. I would think overdrive & 3.08s would be a real headache in wind,on hills...passing traffic.
