Zmax fuel and engine treatment--does anyone use this?

[75USCarrera]

I first saw this on Muscle car tv as an advertisement with Carroll Shelby as a spokesman. Here is an interesting link with "the story of zmax":

Also, here is the home page.

I ordered the kit with fuel, crank case and transmission treatment, but havent used it yet. Whats amazing is according to the instructions, you pour it into a FULL crankcase and supposedly it gets soaked up in the metal.

Has anyone used this product...what is the scoop? Is it a waste of money?

I heard that stuff was a scam - just mineral oil - sure looks like it. You can pick up a bottle at CVS for $1, not that I would put that in a motor.

Carroll Shelby would shill for Massengil for the right amount of money.

Is it a waste of money?

Yes

I have forgotten which agency? FTC? maybe has disproven the claims of many of these type of products..

[Oh Haha]

Carroll Shelby is an icon to many.

I'm disappointed that he speaks so highly of ZMax.

I'm sure he doesn't need the money. Maybe the proceeds go to his charity for kids?
