    My dad had an 82 that got around 18 in town and better on the highway. Wasn't the fastest rig but it made many trips in the mountains of Idaho with no problems. /forums/images/graemlins/thumb.gif

    My 82 K20 stepside gets between 15-22 mpg,(6.2diesel)in mostly stop and go and urban nightmare traffic,I havent gone on the highway with it much yet,at least for any distance,til I get better tires and upgrade my tranny lines,and find out why it wont come out of 4hi--mileage might get better when I can put it in real 2wd,and not have all the shafts turning with the hubs unlocked..all in all,pretty impressive mileage for a fairly heavy 3/4 ton pickup--a K5 might be lighter,and get even better mileage.You can get away with higher gears(or bigger tires without a gear change)more with the diesel,they like to pull,at lower rpm than a gas motor,they dont like to wind out,the govenor will let it get up to about 3600 rpm or so--hmmm--same rpm my briggs and stratton lawnmower tops out at! /forums/images/graemlins/thinking.gif /forums/images/graemlins/rotfl.gif
