I get 16 mpg in town consistently. In a recent trip, I got 17.5 on the highway traveling 60 miles per hour, but that was with some contrary winds. The best I've done on the highway is 18.75

I find wind is my biggest hindrance to good mileage.

Mine is a 1965 C-10 with the following:

283 CID Engine
Holley 4360 Economaster 4-barrel Carb
ME Wagner Dual-flow PCV Valve with a custom designed catch can system
Headers
Dual exhaust with X-pipe
SM 420 Transmission
3.08 rear end
29" tires

Also, I use ethanol free gasoline exclusively. I also use AMSOIL synthetic oil and their oil and air filters.
