Easy to Use

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. The extra 12oz Small Engine Formula bottle can be used in motorcycles, marine engines, lawn equipment, generators, ATVs and more.

zMAX does not replace your regular oil and will not overfill your normal oil level because it soaks into metal.

How often should you use zMAX?

The zMAX Power System treatment is recommended every 6 months or 6,000 miles, whichever comes first. 

Some vehicles have "Sealed Transmissionss" (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. zMAX will not void the manufacturer's warranty that comes with your vehicle.
