Why would the Ford V-10 get 20% better fuel mileage?
Just because it's a "Ford"?
That's not what I was trying to say. I was saying see 10 mpg and 8 towing with both motors. My uncles 2005 F-350 with the V-10 is a 4x4 with 4.30 gears so it pulls great but it does not pass many gas stations. I guess he does not care since he owns 3 stations.
I have a friend with a 2006 3500 with the 8.1. Its a crew cab dually 4x4 and he said he has never seen above the high 9's and towing a 5th wheel he got 7.2 last year on his annual trip to Florida. He is retired GM guy, you know about 52, and he takes it easy.
With either truck I would think 10 is a good average. You may be able to squeak out 12 with 3.73's but these trucks need low gears to take advantage of the power band of the big gas engines.
