has anyone ever heard of motor silk it was on the news to night? the patent is held by us gov. it is added to engine, trans, rear end and fuel. it has been used by nasa and the military for 10 yars. it is to bond with the metal and will remove carbon, tarnish and corrosion. reduce friction by 85 % and wear by 90% and improve miliage by 5- 10%. one treatment lasts 100,000 miles. if it is 30 % true this is some snake oil. sorry i dont know how to a link but just type in motor silk. tell me what you think. robert
