I agree, as long as the
oil makes it to the point of lubrication it is enough pressure. The pressure inside your main bearing reach 1000's of psig in the hydraulic wedge. In fact heavier
oil usually causes less
oil to get where it is needed. For example instead of flowing through the rocker arm bearings and valve stem orfice the thicker oil just overflows the rocker arm and drains into the head. Instead of the oil flowing through you roller bearings in your lifters it flows around etc.
It doesnt take much oil, look at your wheel bearings, There is zero oil circulation, only the oil in the grease lubricates for thousands of miles. Same with your alternator. You are much better off with lighter weight oil then heavier oil.
