Whether or not someone says the same thing about Marvel Mystery Oil (which is little more than souped up tranny fluid) is irrelevant. As for Shelby, he does not need a "hand" to feed him......his days of needing cash were over long ago.... I would say his name is worth far more than any cash he may (or may not have) received from an endorsement.
There ARE people out there who actually test and prove certain products instead of just lying to everyone about it. Shelby is one of them.
And thank you for mentioning the Slick 50 phenomena....it works for a short time to reduce friction, then coats everything and causes more problems. AND, you NEVER use a friction additive during a BREAK IN.......the very term used for the 'time-period' in question should give someone a clue to that fact.
You can remain a pessimist all you care to, but you can't erase decades of proof, and years of successful use by the millions who swear by it (instead of AT it).
Z-Max works. Z-Max leaves no build-up or residue. It simply saves your large investment............By the way, it WILL shave some time off your ET's...........just make sure your rings have seated properly BEFORE ever using it.
(and NO.......I don't sell the stuff.......nothing to gain, except maybe to get someone else to enjoy it's benefits). :burnout:
