sorry if this is just stupid but i was up late lastnight and saw the z max infomercial at first i was just watching to make fun of it but then Carrol Shelby creator of the shelby cobra mustang and series 1 was in it, he says he puts it in every series 1 before it leaves the factory, now if u dont know what it is, its got a chemical that is supposed to soak into the metal of the cylinder walls and reduce friction and insure a longer life, at that point i was like if Carrol Shelby puts it into all of his cars why not, then i heard that it was used in some F1 cars so what do u think??

 

Yes... supposedly it's just mineral oil or something like that. Don't waste your money. =)
