I was thinking about using it because they say it breaks up carbon deposits and reduces blow-by and soaks into metal giving your engine more life. Anyone have an experiences with ZMAX?

 

I tried it about a year ago on my Teg. I used the fuel system cleaner and the oil treatment but didn't bother putting in the tranny lube. To be honest with you I didn't notice any improvement including fuel mileage or power. It might be due to the fact that I kept my car in pretty good condition throughout it's life. However it doesn't mean you shouldn't try it. I also had a 88 Legend that made an awful lifter tick and I used Zmax on that car. It help considerably with the noise and smooth out my idle. This lasted for about 8000 miles and everything went back to its usual self.
