Square Diesel 4X4 Burb Mileage???
I am looking at a 4X4 burb with the diesel. What kind of mileage can I expect to get on a factory setup? Are there any upgrades that make it get better mileage?

Re: Square Diesel 4X4 Burb Mileage???
Should get 18-22,maybe 24 mpg,if it's got overdrive. A couple few less without that,unless you drive slower. But,at least 18.

Re: Square Diesel 4X4 Burb Mileage???
You can have the injection pump tuned as well, either for mileage or power. We had an '83 when I was a kid that had the pump worked, and it would click off 22 all day long with a TH400, 31's and 3.42 gears. I loved that truck.

Re: Square Diesel 4X4 Burb Mileage???
2wd may get a couple better MPG. These motors are all about torque,so not many factors detract from the mileage. They don't work harder till you add a lot of drag/weight. My '91 3/4t 4wd had 4.10s,4L80E,and 12.50/35-16 mud tires on 10" steel wheels and got 22mpg with 1000# of tools/cargo

Even with 4x4 they're good on fuel. They take a square from thirsty beast to pretty economical as far as full sized trucks go, even against the new stuff.

Re: Square Diesel 4X4 Burb Mileage???
Yep,they're the classic 4wd that makes sense for today...better than many new trucks...even with big tires!!
