Lol yep, sometimes I think we're all overthinking this and even if we just used bulk dino oil and dirt cheap filters changed once in a while, our engines would last just as long as running a diet of say M1, RP, Amsoil and Fram Ultra's.
It'd be neat to see a controlled study of identical vehicles with the same driving routes, with one group using top notch synthetic and top notch filters, and the other running jiffy lube oils and bottom barrel filters.
