Whoever says thicker is always better at wear and tear who just lives in yesterday and not in the present
Its not better, but if car is designed for 0w-20 but oil comes up looking like 0w-10, then perhaps 0w-30 will be better suited (it will look like 0w-20)
Engines are not designed for a grade like that. They can have designs that tolerate low HT/HS oils without excessive wear, but that doesn’t in any way preclude the use of a thicker oil. CarfriendXX didn’t understand what he was saying in that post nor does he understand the basic physics of wear.
