Summer diesel - city 13-14 hwy 15-16
Winter diesel - city 12-13 hwy 14-15
Granded this isn't apples to apples but I went from 3.73's to 4.30's in my '06 6.0L with 35's and lost .5 mpg
so hopefully my outcome will be the same if not better.
I see, Do you know what you were getting before the 35's? How bad did they hurt ya?
