Looking at http://www.chevroletforum.com a guy posted that he was getting 18MPG with his 4.3L V6. That is in a 2000 blazer though. Your best bet would be to fuel it up as close to empty as you can and do the math yourself. Lots of factors that influence your fuel mileage though so not every truck will be the same (weight of people in truck, how heavy your right foot is, gearing that came from factory, tire wear..)

I had an 04 Silverado 4.3 auto reg. cab work truck at the same time my cousin had an 03 S10 4.3 auto reg. cab. and I was getting 25 mixed driving while he was getting 23 mixed driving. Mine as plain jane and his was the ZQ8 so that might have made a differnce.

My 07 is a W/T model with the 5 speed trans. and bolt on mods. I managed 26.9 mpg on my last tank. During the winter it drops to 23+ to 24+ mpg.
