a little late to the party here, but with my new 2014 6.2 I left my second trip alone and have not reset MPG on that tripometer. Life since I've owned it, had 250ish miles when I got it, its averaged 17.7 all conditions. There is a 300 mile round trip to Iowa to get my 72 Suburban as well. It got 11.6 towing that pig home.

I've gotten as good as 22 on a trip running 70 on an entire tank, and has done as poor as 15 now that it has gotten cold and added idle time is involved.

Its doing better than the 2010 5.3 Suburban we traded in on it.
