2008 Ford F-250 Super Duty XL 4dr Crew Cab SB (5.4L 8cyl 6M)
OK I will admit I have an 6 inch lift with 37 inch tires but i get no better than 12mpg going easy on the throttle on the frwy and 7 mpg pulling my 7000 lb trailer(total B.S.). My V10 did better than this, what gives? Is changing the gear ratio to 4.30 the ticket for some improvement over the 3.73. This truck is history unless something comes out about improving the mileage
The diesel is powerful, truck looks great, interior majorly improved
Better mileage, 6 speed transmission, navigation standard not option
