Never used it but if Carroll Shelby "Puts his name on it" then it may be worth a try...or maybe he owns stock in the company LOL. I hesitate at any oil additive. Snake oil IMHO.
I've used Zmax in one of my trucks a few years ago and it does pretty good figured it wouldn't hurt keeping everything with less friction as its advertised.
Too expensive... $40 for a little kit? Yeah right... I pay enough for oil changes, fuel filters, and the occasional fuel additives I already use like seafoam and 2 stroke oil.
Unless it works miracles and they give me free beer for buying it, I'll pass...

I used it on my Blazer I had years ago.
Now I used the grey bottle Diesel Clean I believe that's the right name. It also has a red, and white bottles too.
Can tell the difference when I don't use it seems a little harder to start after running a tank through w/o it.
