Thus my point... The numbers were incorrect, and thats what I was pointing out. Purely from a fluid-dynamical standpoint.

However, based upon the HT/HS data, and the fact that it is ACEA B3/B4-02, youll see that M1 15w-50 is amongt the best oils out there... Becasue these specs are the basis of the MB 229.x series (and Id bet the 228.x) oil specs.

0w-40 has a lower HT/HS value, but apparently a higher or more sophisitcated additive package (plus the fact that the lower visc. yields a higher MPG, which is required for the 229.5 spec).
