What is the DATE of this article ?
Must be at minimum 11 to 12 years, and refers to work or tests that are at least twice as old !
Plus Nevada Desert Research Institute has never to the knowledge of current profesors did any such work or tests.
Same goes for the Engineering Dpt of CAL Poly.
No one currently there has any knowledge or any available information to support the claims in the article.
It is not that 400 mesh PTFE poweder in Oil or FRAM Oil Filter is of no value and 15 cents worth of it used to be sold dilluted in Oil for $19.95 - but the fact that the claims are problably not true about the "research" and testing of PTFE.
Petrolon has been out of business for years !!!
