I have a 74 K5. Under the best (highway and warm) conditions I get maybe 12.5 mpg. Regular running around and some 4 wheelin is more like 9 mpg. I have a 350 4 speed with a coverted part time np203. Is this all I should expect?

Thats not to bad! Before I quit work I started a gas tracker for my own curiousity. I have a TBI 350 with an Overdrive 700r4. Some of the low ratings where from letting the truck sit and warm up in the cold or running 4wd on the highway to back and forth.

I get about 9 around town. My truck has a basically stock engine, 4.10's, 35's, 4" lift and a 700. I have no idea on what it gets on the freeway, I will find that out this weekend.
