This is the fourth oil change since new, It's a little early but it was taken before a 2000 mile trip.

The fuel dilution has come down this change. As an experiment, I minimized the use of the transmission "tow/haul" mode. My theory was that high rpm closed throttle events might be a possible source of the high fuel dilution. I only used t/h to descend steep grades. Time will tell if there's any merit to the theory.
Otherwise, everything seems to be wearing as I would expect.
