2008 Ford F-350 Super Duty FX4 4dr Crew Cab 4WD SB (5.4L 8cyl 6M)
Fuel mileage 7-9 mpg no matter if loaded or not. Most of my driving is short trips 5-10 miles town and country mix. I even drove it to California thinking the open road would help... Best avg was 12.5 mpg on 1000 miles of flat driving with no load. Factory tires were garbage they wore out at 14,000 miles good job Ford. They replaced my radiator at 3000 miles. This is my $50,000 truck. I have owned and bought 5 new Ford super doodies since the new body style and this motor is crap because of the mileage and the truck rides too stiff. The exhaust cleaner is ridiculous.
When Ford recalls my truck and fixes the mileage so I get at least 17 mpg like my other diesel fords.
recall and correct these items fuel mileage radiator leaks and tires This is an American made truck
