I fail to understand your logic. Back in the day some trucks where sold with the same displacement diesel with and without turbos. Over time, and really a short time, the non-turbo was pretty much gone because of more power and better fuel mileage.
And doesn't Ford advertise their smaller turbo/gas engines as "Econo"?

Diesel is a bit of a different animal, although it's a misnomer that the turbo engines get better mileage. Some of the early non turbo diesel pickups could get well over 20 mpg on the highway, but they had no power.

Yes, Ford does brand their gas turbo engines as "Eco", but they really don't get significantly better mileage than N/A gas engines of similar power. Towing, they burn just as much fuel. A 7.3 turbo would probably be overkill. I could see an "Eco" engine of maybe 4.5-5 liters, but engineering one that can handle the same towing duty cycle as the new 7.3 gas or other large gas pickup engines hasn't been figured out yet.

Had an
11 5.0 V8 N/A regular driving it got 14mpg towing 8.2 if I was lucky after 6 months of that **** traded it in on a

11 3.5 eco regular driving it gets 16mpg towing it gets 10mpg

18 3.5 eco regular driving 17.6mpg towing it gets 10.7mpg

I would say the 3.5 eco does significantly better than the N/A engine everyday anyday :D


Prior to that had a 08 350 dually that pulled a 14k 5th wheel that got 14mpg regular driving and 8.5mpgs towing the 5th
