Depends on which diesel you are talking about. With the same rear and and tranny gearing my 2v 5.4 will outrun my 7.3 by a wide margain getting up to highway speed, so I can't imagine any v10 having a problem with it. The 7.3 gets a lot better mpg's, so it would win 2 out of 3 against the v10. A 3v v10 will accelerate on par with any psd and will get the same or better mpg's than the 6.0 and 6.4. So the v10 "could" win 3 out of 3 against the 6.0 or 6.4 depending on whose mpg numbers you use, but only 1 out of 3 against the 7.3. My next door neighbor gets 9 mpg's out of his 6.0 and it's a regular cab xl with nothing in it but him, so he's not beating too many people when it comes to mpg's.

That some get one thing, some get another, with the exact same vehicle.
Dunno why, just happens.

Is your neighbor missing an injector or two? I am mad mine only gets 9 mpg towing my 8,000 pound brick wall of a toy hauler. I am sorry, but there is no way any v10 will come close in mileage to any 6.0 that is in proper running order. I will even give you a v10 with some minor mods like an air intake and programmer, regular cab, short bed and a lifted crew cab 1 ton long bed 6.0. Ain't gonna happen.

I didn't say anything about the 6.4, but the 6.0 gets roughly the same mileage as the 7.3. The 6.0 in stock or modded form gets great mileage, unless you are missing an injector.

Not at 75 mph and through major mountain passes at 7k feet. I get 12 when towing like most people at 55/60.

Last time I checked-you were not in my truck when I was on vacation.

All kidding aside, 9 mpg for a V10 is not that bad at all. I would have expected a little worse.

The absolute worst mileage this truck has ever got was 7.5, and that was on a trip returning from Arkansas @ 65mph into a 20-30mph headwind.

It will be interesting to see if my friend with the 6.4 gets better mpg as he hits 10k miles, because I'm slowly creeping up on his mpg.
I do have another friend with a Toyota Tundra who pulls a 8k lb camper, he get 4 mpg when towing. I have to mention my towing mpg all the time to him. Then tell him he would get better mpg if he didn't burn rice.

In the days of the 6.9 and 7.3 the big advantages of the diesel were that they got a lot better mpg's, diesel was cheaper than gas, they were easier to work on, more reliable and didn't cost that much more than a gasser to buy new. Since the 6.0 came out, they have gotten less reliable(while gasser quality has improved greatly), diesel costs more than gas, the mpg advantage is so close that it is offest by the price of fuel and the gasser is now easier to work on.

I finally drove a 7.3 yesterday to pick up lunch as I had a 16' trailer behind mine with a broken landing leg. Sorry to all the 7.3 owners, but if yours is stock, don't try and come after a 6.4. You'll get embarrassed. To those who have never driven a 6.4 and think it's like a 7.3, or has the same power or less, you really need to drive one...Then this thread would die, or get renamed the 7.3PSD vs V10 thread.

I "borrowed" my truck for 2 days before I bought it and if it was getting 12 driving down the road, I would have avoided it. Of course, most of my driving is longer distance, on fairly flat ground as the mountains are on my left heading North. BTW, my 6.4 gets the same mileage sitting at a traffic light as the newest Toyota Prius model.
