Do what you want but:
The Federal Trade Commission has filed a formal complaint on June 6th 1996, accusing Slick 50 of lying when the company claimed that engines need Slick 50 during or after startup; or to prevent premature engine failure; or to reduce engine wear; or that it coats engine parts with PTFE; or that it increases horsepower or fuel efficiency, or lowers engine temperatures or emissions; or that it meets military specs or is used in government vehicles. Which is basically everything that Slick 50 claims in their advertising.
Eventually Slick 50 elected to settle with the FTC. This settlement bars Slick 50 from making any of the above claims about the product and required Slick 50 to distribute at least $10 million in rebates.

What fascinates me is that Slick 50 is no longer allowed to claim a single benefit from using their product. Yet it still sells. People will buy anything. Don't be one of them!
