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).

Current Diesels:
1981 240D (73K)
1982 300CD (169k)
1991 350SD (113k)
1991 300D (228k)
1993 300SD (291k)
1993 300D 2.5T (338k)
1996 Dodge Ram CTD (442k)
1996 Dodge Ram CTD (265k)

Past Diesels:
1983 300D (228K)
1985 300D (233K)
