ZMax
I didn't know where to put this so i will put it here. Has anyone used the ZMax fuel and engine formulas? Is it worth the $30 and is it as good as they say? are there any side effects?

This topic has been brought up many times before. You can do a search on zMax and you will see that other members do not like it. Basically its mineral oil. It eats away at your gaskets and seals. Its bad mojo. I believe that there is a law suit or there was a class action law suit against them.
