Nope, not a stoolie. I'm a automotive enthusiast. I like to try to improve upon designs, efficiency, power, etc. I hold a BS and MS in Mechanical Engineering and have interest in related things. And, I'm interested in things like Zmax who claim to have the answer. I've tried several products, including Prolong, Duralube, Slick 50, and, of course, Zmax. So far, Zmax is THE ONLY PRODUCT I'VE TRIED, THAT SHOWS MEASURABLE IMPROVEMENT AT ALL. Now, I could write a short thesis on why I think Zmax is different, better, yadda, yadda. Instead I will simply refer you to my previous statement in bold type. That makes it easy for clueless people, like you, who just want the simple facts. Besides, as you stated, you've never even tried it! Save your money. I doubt that you'd know how to determine and quantify any improvements.
