ZMAX is currently fighting off a class-action lawsuit because the government found out they fabricated their data. Evidently, ZMAX is just a super-lubricant. Makes everything more slippery, hence the gas mileage/performance increase. I'd just stick to changing the oil on a regular basis.

Probably chlorine based like similar products. Yeah, it lubricates like crazy.... at the same time it slowly attacks and destroys the metal in the engine.
