o yea. to add to the post.
my dad had a f250 v10 and yea it was a little faster off the line then my diesel but it was not fun when he never saw double digits on the MPG (empty!) He was lucky to see 9MPG. with my F350, the lowest I have seen is this past tank at 14.a few MPG. that was all short trips and including an hour idling on the closed freeway and lost of idle time warming up the motor.
