I have run 5k intervals from the start with the Dak, Durango and the
GF's stratus (rip). The benzes are both on 10k intervals, but they take
ALOT more oil [the C32 takes 8.5 Litres] than the Dodges. In another
Email there was a comment about higher levels of Zinc and Phosphorus,
but I don't see it. Here's a report from my truck:

There is a mistake on there, they identify the oil as Shell 5W40, when
in fact it was Mobil1, but then they go on to comment how the
formulation has changed...go figure. Anyway, the numbers are all pretty
much in line the other thing is for some reason the history doesen't
have every single sample and in order, some are skipped. You may notice
the viscosities of the 5w40 and 15w50 are dramatically above the
averages, even after having been used.
