Has anyone used the product ZMax? You can add it to your fuel tank and crankcase?

I was surprised to see Carroll Shelby on one of their commercials stating that he used the product in all his cars. He didn’t name the product, (I’m an incurable cynic) but I have seen the commercial several times over many months. I doubt that I need it for my daily commutes, but I’d look into it if I raced. On a track, of course.

I know someone who spent their money on this product and used it in their vehicle. All they ended up with were some fancy looking bottles.
