April 30, 2008My company just picked up two '06 PSD's as work trucks. Both are stock 4x4's, one short bed, one long bed.
Both trucks are getting about 11-12 MPG, mix of city and dirt road driving. I would have expected better mileage, even with the mix of driving conditions.
I don't want to spend too much money (cause it isn't my money), but I would like to hear from you 6.0 guys as to which mods give you the best real-world MPG increases.
