The FTC has indicated that all of the major companies manufacturing additives, teflon or otherwise, have used deceptive advertising in order to mislead consumers into believing that their products offer advanced engine protection and performance over motor oil alone.
The claims made for Tufoil are the same for the others that have been proven false. Has the FTC approved Tufoil? If it is simply a teflon additive as some of the others, then why would Tufoil work when the others don't?
