The reason I run a Loose (.002+) clearance . is to improve oil flow through the bearing. Bearings need flow to cool the bearing. Heat is the enemy of bearings. tighter clearances, must use a thinner oil to maintain the flow rate, thus 5/20 oil. I love this kind of thread, it makes you think about all the mistakes you made over the past 85 years.
