john the problem with teflon is that in order for teflon to bond to a metal it has to reach 800 degrees!
being this the teflon doesnt bond to your engine and will just clog your filter. if you research on it the company dupont who is the inventor of teflon is against running it in an engine and claims that there would be no benefit! they will not allow companys to use their name on any product! must be really good stuff!!!!!
