zMAX Engine & Fuel Formulas, Engine Additive and Fuel System Cleaner, 12 fl oz bottles

About this deal

This two-bottle system is designed to treat both the engine oil system and fuel system separately, providing a more complete approach to maintaining vehicle performance and efficiency. As zMAX soaks into the metal, it helps disperse carbon deposits that form on internal engine components and within the fuel system. By addressing buildup in both areas, this system supports smoother operation and more consistent performance. The Engine Formula is added to the oil system, where it circulates to critical internal components such as piston rings, cylinder walls, and valve surfaces. The Fuel Formula is added directly to the fuel tank, where it moves through injectors and fuel passages during normal operation. Formulated for compatibility with gasoline and diesel engines, this two-part system is suitable for automotive, powersports, and equipment applications.
