"I have had my 2008 F-350 King Ranch LB with A.R.E cab high shell for 16 mo. I have 15200 miles on it. Would have had more but got hurt and could not drive for 7 mo. The truck has had no problems at all . Fuel miles has been about 13 to 14 in city and 16 to 18 highway with out tow. I use cruise control at 58 to 60 mph. This is after break in on the diesel 6.4.
The gas meter on the truck says on highway 20 to 22 but that wrong. I knew the truck uses more fuel so why gripe about my miles. I think for a truck of this size it does well. I see others complain about miles mpg then why did you buy a big truck in the first place. Every where I go people love the truck. I'm 60 years old and had a few trucks and cars in my life, and I can say this Ford truck is the best truck I have ever had.
Ride great for a big truck, something I have to look for a place to park it because of the size but I don't care it worth it.
This is a no bull report, because I love the truth about my auto good or bad. I use Amsoil CJ-4 5w40 syn.
This will be my last truck till I go home to be with the Lord !!"
