2008 sprinter with the om642 3.0 turbo diesel. In as much as this is 14 yrs old, the oils listed in manual are no longer even produced so I am using the bevo chart recommendations. The mobil 1 euro car is not listed for this engine. The manual doesn’t give a specific weight recommendation, just choices based on ambient temp usage. It confuses me because the only change is at the low temp, all from 0w-30 to 20w-50 show the same upper temp range. So what’s the point in the differences? Like I said, I must be over thinking it, I guess either the 30 or 40 will work equally as well.
