Ford bumps up the mileage on Super-Duty pickups

Ford has decided to make some mid-year running changes to bump the mileage on their biggest vehicles. The SuperDuty pickups generally have a hard time cracking the double digits but then they are designed as work trucks meant to haul large heavy loads. Nonetheless, anyone using one of these beasts to earn a living is bound to have concerns about the rising cost of fuel. Single rear wheel F-250 and F-350 models with the 6.4L diesel get lower final drive ratios going from 3.73:1 to 3.55:1. Combined with a 4-inch deeper chin spoiler helps to yield an extra 1.5mpg. Trucks with the 5.4L gas V-8 get a 0.5mpg bump thanks to a final drive ratio that goes from 4.10 to 3.73. In spite of the changes none of the trucks lose any towing performance. Regular cab diesel models still have a 12,500 lb tow rating.
