You're thinking of ZEX bro. ZEX is a nitrous company, ZMax is this special formula that cleans and protects the motor's internal components. A family friend of mine, who have been driving a cab for years, recommended it and he runs 500K miles on his car without flaw. Just wanted to ask MB Forum is anyone tried it on a MB V12.
