The misunderstandings...
Again, Haas never said "thinner was (always) better". I believe he was only talking about new or newer engines, Haas actually recommended thicker viscosity in aging, higher mileage engines...
Regardless what our Doc H. or BITOG Uni 101????? recommends its the vehicle manufacturers recommendation for the thinnest grade that should be adhered to and your reference manual IMO.
The Doc conducts UOAs liaises with manufacturer and in my view is a unique example perhaps not for others to follow unless you are prepared to follow the same regime ie UOA record monitor, liaise with industry etc.
Departure from OEM guidelines should be on a case by case basis by the owner rather than imply the experience of some individuals practice is acceptable across the board.
I think I need to take break I am getting tired of repeating myself with references back OEM ..............
I how many guys out there read the BITOG oil university and immediately run out to get 0W20.
Exactly.
They do just what the OP has done, ask questions. And in that regard Ali Haas' piece has served it's introductory purpose.
From that point on, "the devil's in the details", which is what's being discussed here.
