This complete car care kit includes the zMAX Fuel and Engine kit, zMAX Ultra Clean and micro-fiber towel. zMAX Micro-lubricant soaks into metal to help disperse carbon deposits. By virtue of reducing these deposits, zMAX helps improve performance, extend engine life, reduce emissions and improve fuel mileage. 

Add 12oz zMAX Fuel Formula to your fuel and 12oz zMAX Engine Formula to the oil. Retreat every 6 months or 6,000 miles.
