z-max
 

has anyone tried this stuff, just curios if it really works especially since
Carroll Shelby put his reputation on it.

Carroll Shelby will do anything for $$ so that means nothing to me.

I've never used that stuff, but for most any additive can you really tell if it does anything?

i realize you can not tell if it does any thing or not, i guess i should have asked if anyone tore down there engine noticed any difference. or fuel mileage increase since that is what it claims.

I'd put it up there with STP, Slick 50, Prolong, and all of those. MIGHT do something to an engine that's really bad but not worth it in the long run.

Oh, and some reading material:
