What Makes zMAX Different
Unlike conventional additives that primarily change the properties of the fluid they’re added to, zMAX uses engine oil, fuel, or transmission fluid as a carrier to reach internal components. The micro-lubricant penetrates metal surfaces, helping reduce friction, wear, and deposit buildup where it matters most.
- Reduces friction and wear
- Helps maintain engine performance
- Helps reduce carbon and deposit buildup
- Supports cleaner, more efficient operation

Real results from real drivers.
My van now has 304,000 miles. I've used zMAX Engine Treatment faithfully with every oil change since 1996. Great investment.
There was no wear whatsoever on the engine cylinders — none. At 325,000 miles I could still see the factory cross-hatch from the cylinder hone. Simply amazing.
Instantly the lifter tick went away and the engine idles extremely steady and smooth, with zero noise. I will forever use this product at every oil change.
