Key item features

  • Dual Treatment: This two-bottle system includes a 12 fl. oz. Engine Formula and a 12 fl. oz. Fuel Formula, designed to treat both the engine oil system and the fuel system separately for comprehensive vehicle maintenance.
  • Performance Enhancement: The formulas work to improve overall performance, leading to smoother starts, enhanced horsepower, and improved fuel mileage.
  • Engine Longevity: By dispersing carbon deposits on internal engine components and within the fuel system, zMAX helps extend engine life and the life of injectors.
  • Emission Reduction: The product contributes to a reduction in emissions, supporting cleaner operation of the vehicle.
  • Deposit Dispersal: As zMAX soaks into metal, it actively disperses carbon deposits that accumulate on internal engine components and within the fuel system.
  • Broad Compatibility: Formulated for compatibility with both gasoline and diesel engines, this two-part system is suitable for automotive, powersports, and various equipment applications.

C-Max penetrates the heated friction areas of the engine. cleans out the fuel pump, lines,and fuel injectors. You can feel the beneficial reaction of adding zMAX Fuel and engine treatment.
