It's curious that you embrace 'these' National Lab. 'scientists' when their hypotheses have the appearance of agreeing with your boric acid argument, but when scientists from other National Labs, who actually study automotive tribology publish 'against' your premises, you appear eager to throw them all under the bus, along with thousands of others in other organizations, linking them all to some master conspiracy, out to destroy the longevity of automobiles, and the pocketbooks of their owners.
