I don't think I ever got better than 12mpg out of a 350. Most times were 10mpg.

Yeah, no kidding!

Even my 3/4 ton 6.0 with 34s on it got 13 in mixed driving.

I don't think I averaged better than 10 or 11 with any half ton, and a small block. And a lot less power to add insult to injury

I've been averaging around 14.5 mpg, but this last tank with some Amsoil PI and getting the rpm's up over 4500 occasionally, I got 15.7. Not to bad for a vehicle with over 200K on the clock.
