    Looking at a 1991 K5 and curious what the typical highway mileage is for this beast. Need to know asap as I am contemplating purchasing it tomorrow.

    Any input would be greatly appreciated....

    If I'm just cruising around 65-70 mph I recon I get about 18 to 20 mpg. But 80 to 100+ mph and your looking at 8 to 12 maybe.

    Mark, I'm assuming that's the imperial gallon your numbers refer to?

    Average for a stock 91 seems to vary between 10 and 15 mpg (US gallon) depending on how and where it's driven.

    I'll second that. When people ask what kind of mileage I get I tell them I do not know. I bought it 'cause I wanted it not cause I needed it. But, if I had to guess, on my '91 I was getting about 10 - 12 mpg with 35's and 3:73 gears. :grin:
