Q: Why should I use MotorMax?

A: The most neglected part of today's sophisticated engine is the cooling system, yet it is at the heart of optimum engine performance. Temperature extremes (both hot and cold) literally destroy vital engine components. As little as one quart of MotorMax:

  • Reduces engine temperatures/prevents overheating
  • Dramatically improves air conditioning output
  • Enhances fuel performance
  • Reduces exhaust emissions
  • Reduces cold temperature engine wear and tear

Q: How much MotorMax do I need?

A: Most automobiles require only one quart of MotorMax added directly to their radiators for improved cooling system performance. Larger/heavier duty vehicles with expanded cooling system capacities may need two quarts of MotorMax and/or a 1:10 ratio of MotorMax to standard water/antifreeze mixtures.

Q: Will MotorMax mix with my existing water/antifreeze mixture?

A: Yes, MotorMax will mix with, and improve the performance of, all existing radiator mixes, including the new extended life antifreeze. MotorMax is not a replacement for antifreeze, but can be used in a water-only coolant environment such as racing or hot weather industrial settings where freezing is not a concern.

Q: Will adding MotorMax to my radiator effect my vehicle's warranty?

A: No, MotorMax has been tested to be completely safe with all engine components and accessories. It is a ph neutral substance, with extensive testing by SGS US Testing Laboratories proving it to be non-corrosive to metal/aluminum surfaces. MotorMax is also backed by a manufacturer's 2 million dollar product liability policy, assuring our customers full protection against any unknown causes of product failure.

Q: How long does MotorMax work, i.e. when should it be replaced?

A: MotorMax is a permanent cooling system treatment, and will work continuously until flushed out of your cooling system as part of your vehicle manufacturer's recommended maintenance intervals (usually 2 year/24,000 miles unless long life anti-freeze has been installed). MotorMax should be added when your normal water/antifreeze mixture is replaced.

Q: What is MotorMax?

A: MotorMax is a biodegradable all natural plant based cooling system additive that has proven to be an extremely effective heat sink. By definition, a heat sink is a substance or device for the absorption or dissipation of unwanted heat.

Q: How does MotorMax work?

A: MotorMax works by absorbing heat it comes into contact with and transfers it equally throughout the engine and cooling system. Through this process, MotorMax equalizes the block temperature front to back and/or side to side, and helps eliminate hot spots in the engine. Once the coolant mixture is cycled to the radiator, MotorMax transfers heat much more efficiently than any water or water/antifreeze mixture.

Q: Will MotorMax harm anything in my engine?

A: No. MotorMax is non-corrosive, biodegradable and compatible with all internal engine parts, seals, hoses and accessory equipment. Independent laboratory testing confirms MotorMax is pH neutral and compatible with aluminum components.

Q: How often do I have to add MotorMax?

A: MotorMax works continuously once added to your cooling system, and need not be renewed until flushed out during normal system maintenance. Refer to and follow the recommended flushing requirements of your engine manufacturer's maintenance schedule for the cooling system. MotorMax can be added anytime, and should be replenished when flushing and changing your antifreeze.

Q: Is MotorMax safe to use in both gas and diesel engines?

A: Yes.

Q: In diesel engines, will MotorMax effect any of the Supplemental Cooling Additives (SCAs) in the cooling system?

A: No, but attention should be paid to the dilution effect of adding MotorMax in large capacity systems much as in the same manner as adding water.

Q: What should I expect to see after using MotorMax?

A: The first thing you will notice is your vehicle will get to operating temperature faster. Secondly, you'll notice significantly improved air conditioning output at the interior ducts. Additionally, overall engine bay temperatures will be 10 to 30 degrees cooler depending on ambient air temperatures. Engine temperature reductions are often dramatic enough to notice immediate changes in dash gauge readings.

Q: How can a radiator additive reduce AC temps so dramatically?

A: The same way heat is drawn from your home in the winter months, an automotive AC condenser draws and absorbs heat that is driven away from the radiator, thereby reducing the efficiency of the condenser. By reducing water temperature and increasing the radiator's efficiency, much less heat is being absorbed by the AC condenser, allowing it to operate much more efficiently.

Q: What is the shelf life of MotorMax?

A: The product in the original sealed container has an indefinite shelf life. MotorMax is freeze/thaw stable.

Q: Is MotorMax compatible with commercial antifreezes?

A: Yes. Independent laboratory tests reflect that when MotorMax was added to antifreeze, its boiling and freezing points, pH level, survival of microbial population and effect on dimensional stability of rubber radiator hose was not changed.

Q: Will MotorMax effect my emissions/engine management system?

A: No. Your thermostat still controls water flow by opening and closing at pre-set temperatures. As such, your thermostat will control temperatures allowing your engine management systems to operate in the correct range. MotorMax works most effectively at reducing destructive heat above/beyond the thermostat setting, and in bringing temperatures up to optimal range in cold conditions, reducing destructive cold weather wear and tear.
