Talking about oils (again) -MBUSA changed the policy to use synthetic after year 2000 and our 1998 ML320 run on dino oils for few years making 13,000 intervals (dictated by FSS) just fine.
Even my vehicles don't require synthetics, I do use them as the price difference is not that big in US and I appreciate additional protection.
Like last year oil pump failed on our W124 and I run the engine for few minutes with no oil pressure. I checked it out later, while replacing the head gasket and the cylinders at 292k miles are still having perfect honing marks from Stuttgart.
Also switching to synthetic the engines drop oil usage. That always coming with me fixing old orings, so not real proof, but I like the impression.
BTW my stepbro divorced Dutch wife after 20 years of marriage, so the "harder to get is appreciated longer" did not work in this case.
