zMAX Power System

12oz. Fuel Formula | 12oz. Engine Formula | 6oz. Trans Formula | Small Engine Formula

Simply pour zMAX into your fuel system (12oz.), your engine (12oz.), and transmission (6oz.) or have zMAX installed by your mechanic at your next oil change. The bottles are clearly marked. zMAX does not replace your regular oil. Using zMAX will not overfill your normal oil level, because it soaks into metal. The zMAX Power System treatment is recommended every 6 months or 6,000 miles, whichever comes first. By properly replenishing zMAX, your engine will receive nonstop protection.

zMAX will not void the manufacturer's warranty that comes with your vehicle.

Some vehicles have “Sealed Transmissions” (No place to fill or check the fluid level) which also means no place to add zMAX Transmission Formula. Verify with your Owner’s Manual if this applies to your vehicle.
