MPG question

Hey all,

So I was wondering what type of MPG everyone else here was getting with their trucks, and please also give some specs and info on your truck so we can compare and get a good idea on which trucks are in the same general category. I have a 79 F250 4x4, 300 I6 with a 4 speed and just had it rebuilt and upgraded and am wondering what type of MPG I should be expecting. I was expecting to get about the same as I got before which was about 15. But so far it's no where near that. Please post your MPG and truck info.

Thanks.

I have two dents. A 76 2wd 300 6. 410 I think gears 31" tires t18 4 speed. Engine all stock except for electric fans and a k&n air filter it gets around 17mpg. My other is a 73 2wd 390 Holley 770 cfm carb. Headers dual 2.5" exhaust. 410 I think gears. 33 12.5 16.5" tires on the back.It seems like it gets gallons per mile. But it gets around 7mpg

thanks guys, I was hoping I could be a bit closer to 14,15 but the motor is new. Still only has 800 miles on it since the rebuild and upgrade so it might take a bit but was just curious if I should start looking at swapping out the carb to something smaller. Also, just put on new tires, BF Goodrich 235/85/R16

While we're at it, we might as well speculate as to why we get mileage figures like these. The most obvious factor is that our trucks have the aerodynamics of a barn door. But, surely, there's more to it than just that.
