the ability of the oil to get to the head is nothing to do with its consistency its down to the pump.
and its been something that's been found on head inspection.
people who take engines apart will say that when they take a engine apart that has used a good quality thicker oil, it will still be evident on engine parts in the head.
i.e. its still stuck up there.
at the end of the day anyone can use what they want.
but im going with the thick brigade
