Show me the data that supports this claim..
German oil specs are well known. The key to understanding it is to look at the tests performed, the amount of tests performed, the length of them, etc. Ringlands must stay clear, wear, longevity, etc.
My VW 508 application says 10,000 mile oil change intervals due to all this. GM's dexos1 intervals are about 7,500 miles by comparison, perfectly in line with how stringent the specs are.
Kia lets you go around 6,000 miles typically in their engines, and allows conventional SN oil. See the pattern here? Let the engineers at these companies bring "the data" as you whine about.

Read that, see some tests performed, then get back with us about what you've learned.
Until then, don't try to second guess Mercedes, BMW, VW, Audi, & Porsche engineers.
Blah blah blah - that's all on paper bucko, not IRL - are you new to vehicle ownership, just curious??.. and you still haven't answered the question and haven't provided a scintilla of evidence that supports your claim that all your "approvals" with German base oil requirements blah blah, translate to longer engine life. I on the other hand provided two pieces of data that suggests that there is no decided advantage, as far as engine longevity is concerned, to using a lube with your German approvals v. your run of the mill house brand with API/ILSAC approvals. In fact Newton's earlier post here in this thread appears (to me at least) to support my position. That for the avg passenger car vehicle, there is no demonstrable benefit to using a fancy shmancy, high priced lube made with grp4/5 base oils and a laundry list of German approvals.
Your turn bucko...
Yes if Grp4 and 5 were really that great why haven't we seen an undeniable leap in engine life to say 700k miles at least after all its nearly twice as expensive. But say I'll let the rocket scientists battle it out.
