Any antique 6.2 diesel with the CORRECT gears will get 20mpg (even my 3sp turbo 400 suburban did), your blazer could come with one.

Trouble is the gears that get good MPGs would be tough to get in 4wd without blowing a hole in your wallet, but then again 6.2 blazers are a dime a dozen.

The 6.2 gets good mileage but are low HP; to offroad a 5sp granny transmission swap would be your best bet then attempt to regear the 4wd (no easy task)

A decent 6.2 suburban with a 5sp and high gears usually gets in the 26-30mpg area depending on how you drive, I can only imagine a blazer would get that or a little more if you can get the motor running correctly tuned a little rough and get a nice stick shift in it. Of coarse assuming you don't put on 385 tires and lift the thing.

Its too bad GM didn't sell the 6.2's with the proper 5sp manual so they could get excellent FE (for a large lumbering vehicle) 6.2's would likely make a nice fit into any large 70's or 80's car but they were never sold that way.
