    I just drove my rig to Memphis and back(roughly 500 miles each way)and I averaged it out to be about 9 miles per gallon.When I'm in the boonies I get more like 3 miles per gallon.Or is it 3 gallons per mile?I forget.:doah:

    x2..

    My 79 C10 with a 305 and Edelbrock 600 carb gets as much as 15 mpg,if I drive like an egg is between my foot and the gas pedal,and I'll die if the shell breaks...drive it like all the other boobs in town do,and I'd get less than ten I bet..it gets much less mpg when its below 30 degrees out..cold starts and short trips really kill gas mileage..

    I have a hand choke,and use it only to get it started,and for a few hundred feet past my driveway..it helps a lot to stretch the fuel,an automatic choke that never fully opens in cold weather kills mileage!..having a working EFE valve(heat riser) and hot air to the air cleaner is important for good mileage too..

    The 82 K20's 6.2 diesel gets between 16-22 mpg,even with the plow on it..:D the mileage doesn't seem to change empty or loaded down..gotta love da diesel...:laugh: ..

    I drive hammer down 80 mile round trip to work. Cruise at 70 to 75 on the interstate. Pedal to the floor from red lights. Well, truth be told, that's how you drive a Cummins. With the sb400 I got about 8mpg. Needless to say it did not see the road too much. I've had the 4bt in it for about 3 weeks now.

    I was getting about 11 but I was adjusting my Edelbrock last week and found out the Prior Owner had the screws turned out 4-1/2 turns. So I leaned it out and now I get about 13 with combo city/hwy. '86 burb/350/700R4/4.10's/31's
