M1 5w40 TDT in my OM601/190d, Rotella T6 in my 300SD, and M1 15w50 High Performance in my 420SEL/M116.
The TDI uses its special Castrol low-ash diesel oil from the dealer...I don't change that one.
Brother's E320 uses 0w40 M1 euro car forumla, both of my dad's cars use Rotella T6, and my uncle runs 5w20 M1 in his Crown Vic Interceptor.
No idea whats in my sister's VW, probably 0w40 M1 or something.
That about covers it. Oh, my lawn machine has Shell SAE30 dino oil in it...
