I attribute the slight increase to driveline break-in. Just a thought but it is interesting.

Yes winter blends do as well as anti freeze elements in case you get some water. I concur with the driveline break in theory. If you keep the car long enough it should peak and then start to taper down at roughly the same rate as the break in changes to wear out. If Hawk keeps the data rolling and doesn't change driving habits we may actually start to see the decline in a couple of years or so. I have seen loads of break in and wear out data on car components before (most artificially induced on test rigs) but this is the first time I have seen reliable data and results on a whole car. This is way to study things not the "I can't wait to see sombody drive both and tell me which is better" crap going on in some threads.
