Has anyone heard of or tried the fuel pills made by Bioperformance .They are pills you drop in your fuel tank ,they disolve and they are to give 18-22% as much as 35% increase in fuel mileage. I was approched in mid- jan, at the campworld store in bowling green by a guy who gave me some of these pills to try on my way home from vacation.He also gave me information about the web site, (www.agodsend4us.mybpbiz.com )to futher check this out.I was leary about putting this in my fuel tank till I heard/learned more about it.In diesel it raise the cetane level for better combustion ,which means better mileage. I have not read enough about gas to see the effects . Anyone use/using this TEAM3360
