Anybody put any miles on after the fix? Interested to know about fuel economy.
Mileage should not really be affected. The D that I have was produced in the fall 2011 with all the changes already implemented, and my mileage is quite good considering the slow city traffic in the summer and the cold winter driving in stop and go.
Worst city mileage was 22USMPG in -30 to -40 Weather.
Best Hwy mileage at 70mph is around 42-44USMPG.
All this with a motor not really settled in yet.
