Many people at this site agree that Moly in motor oil is really good-that it reduces friction and wear. How were they able to make Moly in motor oils effective but the old Moly oil additives did not seem to work? On a somewhat related issue, there used to be at least one graphite motor oil, and there were some graphite oil additives. But graphite in motor oils apparently was not effective-as far as I know there are no graphite motor oils today. Why did graphite not work?
