Wow crazy all the different opinions. 15W50, 10W40, 20W50, 5W30
I should have started a poll.
I once read there is a way to figure out the right
oil by observing the
oil pressure cold and warm at idle and a higher RPM's, can't find the article anymore though. Any insight on that?
That way I could stick to the 15W50 that Rick used for now and see what it gets me.
