6.0L gas RE vs mpg
Anyone guess or estimate the MPG improvement between 4:10 and 3:73 in the new gas GM trucks? How would we determine the mpg improvement switching out from a 4:10 to a 3:73 ... Got about 1100 m...

Thats true too. Winter blend fuel here in Alaska typically drops my 6.0 almost 3mpg. Highway winter driving nets me an average of 12.5mpg, in the summers on the same commute i'll see around 15mpg. I would imagine if your running winter blend fuel that would account for the net mileage loss.
