1998 4.3L Vortec bad gas mileage!

HI, within the last weeks I purchased a used 1998 S-10 with 4.3 vortec and automatic transmission. It's in great condition, not a speck of dirt on the engine, no leaks anywhere, tight transmission, great acceleration, etc etc. But I have one problem: just going three miles to my friends' house I can watch the gas gauge drop nearly 1 increment.. I don't gun it, I usually go a few MPH UNDER the speed limit, slow starts, don't run the AC. It's almost like I have a v-8 under the hood with regards to the gas mileage or something. Anyone have any suggestion or hints or tips on what's wrong? BTW, I only fill the tank with 91 octane. Thanks!

I HAVE THE SAME PROB W/ MY 97. I HAVE NEVER GOTTEN BETTER THAN 20MPG. AND THE WORST HAS BEEN 14MPG, THATS WHEN ALL I DID WAS FULL THROTTLE DRIVING. I USUALLY AVERAGE 16MPG, JUST LIKE A V8. I PUT THE K&N GEN 2 AND EXHAUST, HELPED A LITTLE BIT, BUT NOT MUCH. I THINK AN IGNITION AND SOME PULLIES, BUT NOT TOO SURE. LET ME KNOW IF YOU FIND OUT ANYTHING.

I MEAN ITS PRETTY SAD THAT MY WIFES 5.7L TAHOE GET BETTER MILEAGE THAN MY 4.3
