Exactly. When has a BMW engine failed due to lubrication failure within the 50K/4yr warranty period? I'd guess never. So sweating the spec is irrelevant. Good synthetic oil, proper viscosity (or at least close), regular change intervals. Now worry about all the stuff that will fail early or should be replaced as a preventive measure. I'm thinking diff fluid, PS fluid, trans fluid (all that "lifetime" stuff.)
