How much of a difference do really think there is going to be in MPG in the new 6.7 vs 6.4? The reason I ask is I am thinking of getting a 2010 F-250 because its the last year of the 6.4. I think most of the issues have been worked out and it doesnt need the DEF. Also I dont like to buy the first year of an engine so I would then have to wait for the 2012 model. If you were me would you wait or just buy the 2010 6.4L??
