Re: Oil Additive
I can say this:<br /><br />TFTE (Teflon) is NOT designed to be used in an internal combustion engine. Heated under pressure, the molecules begin to clump and stick together, increasing the friction coefficient instead of lowering it. I can't speak to the other additives (prolong, duralube, etc.) but I wouldn't use any product that contains any form of TFTE.<br /><br />Just my $.02
