Dramatic side by side demo of motors from the MotorMAX infomercial.

"If you take a conservative figure of 30 additional miles per tank for each of our 32 fleet vehicles, multiplied by 50 weeks of driving, the miles per gallon saved would be about 42,000 miles per year. At the current high cost of fuel, I recommend that we use MotorMAX in all the company vehicles."

"Since adding MotorMAX to my heat exchanger reservoir, my engine temperature this summer stayed pegged at 200 degrees, and never rose to the temperature extremes that concerned me previously."

"I feel that the product has significant value and we here in Tulsa (EMSA) will be using the product in all of our fleet vehicles."

"I would highly recommend MotorMAX to anyone with commercial or recreational marine applications concerned about reducing operating temperatures in their engines. "

"After we put the MotorMAX in and I ran my truck my fuel mileage increased. ... with an 8000 lb. Load I received 8.2 miles per gallon fuel mileage and with a 48,000 lb. load my fuel mileage was 6.9 miles per gallon. That is an increase in mileage range of 1.1 to 2.4 miles per gallon of fuel. My temp gauge also showed a 5 degree drop in temperature."

"Our team recently began testing the MotorMAX product on our NASCAR Busch North Series car, much to our liking, I believe MotorMAX contributed to our recent win at New Thompson Speedway."

MotorMAX radiator additive is effective in all water cooled engines and equipment. Simply add one quart of MotorMAX radiator additive for standard automotive engine applications, or add MotorMAX in a 1:10 ratio for severe duty, commercial trucking/fleet or racing engine applications. MotorMAX radiator additive is a one time treatment, and works continuously until your engine cooling system is flushed according to your manufacturer's suggested routine maintenance schedule. MotorMAX is compatible with all mixtures and is equally effective when mixed with water alone where antifreeze is not required.

To preface, my Koenig Competition Ferrari runs a mid-engine, SBC350, mildly tuned(300hp), but ran the upper limits of heat levels (200°>225°) as there are small rads/fans in front of each rear wheel. I must say that when I approached you with the discussion to try MotorMAX, I was somewhat dubious as to what was claimed! I have no doubts any more! My car will run all day at 190°>200°, put it through some hard driving, it will register around 210°.

I can't say enough about MotorMAX! It has taken the 'nervousness' out of me, as engine temperature is now reasonable! My rad fans are not running continuously, giving my alternator/battery some breathing room!

Thanks again,
Sandy Cowan


Frequently Asked Questions

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.

"I wanted to take a moment and thank you for the MotorMAX you provided for my boat, and tell you about my great experience with this product. I operate a 26 foot Wellcraft, powered by an inboard/outboard Mercruiser 7.4 L 454 EFI fresh water cooled engine. Prior to using MotorMAX, my engine temperature would hover around 220 degrees, and would reach up to 230 degrees (very close to overheating). Since adding MotorMAX to my heat exchanger reservoir, my engine temperature this summer stayed pegged at 200 degrees, and never rose to the temperature extremes that concerned me previously.

I would highly recommend MotorMAX to anyone with commercial or recreational marine applications concerned about reducing operating temperatures in their engines.

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, absolutely.

We have tested MotorMAX in four of our Kenworth tractors equipped with Cummings engines and are pleased with the results.

We found that the average fuel savings was 5%. This translates into a considerable reduction in our annual fuel purchases. With the competitive pressures in this business, a major savings with MotorMAX makes good business sense.

Our drivers are happy with the increased air conditioning output that MotorMAX has provided. This is a good additional benefit.

You can be sure you'll hear from my trucking friends who also plan to use your product.

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.

Q: How much does MotorMAX cost?
A: Just $24.95 plus $5 shipping and handling for a one-quart treatment of MotorMAX. It will last until your next radiator flush or 100,000 miles.

I drive a 2000 Freightliner classic condo with 730,000 Kms. My truck used to overheat big time. The thermostats were good, and all the other systems checked out fine. Although I was only hauling about 20,000 pounds, I actually had to pull over three times in the hills outside Denver because the overheating buzzer kept coming on.

My brother had me try adding 5 quarts of MotorMAX to my radiator. The temperature came down to 175-185 degrees right away, and I noticed my cooling fan was cycling on less often.
MotorMAX works great and I am going to put it in my half ton next. I'd highly recommend this product.

The MotorMAX Advantage

Faster warm up: In a thermostat controlled cooling system, MotorMAX will absorb the heat of internal engine components and transfer it evenly throughout the engine. Since water with MotorMAX is acting like a heat sink, engine temperatures will rise faster, reducing both the time for warm-up and cold start wear and tear. In addition, cab heater output is noticeably improved in severe cold due to MotorMAX's ability to carry more heat through the heater core than standard coolant mixtures.

Reduced water temperature: Once the thermostat opens, MotorMAX will transfer the heat it has absorbed into the radiator. MotorMAX's ability to discharge heat dramatically when exposed to airflow allows the radiator to more efficiently remove heat from the MotorMAX/coolant mixture. Individual results vary depending on the size and volume of your cooling system. In a variety of applications, MotorMAX has reduced engine temperatures an average of 15-20 degrees, with reductions of up to 30 degrees seen in select installations.

Reduced internal engine parts temperature: Acting like a heat sink, MotorMAX has the ability to absorb heat from internal engine parts. Reducing operating temperatures of internal parts has a major impact on wear and tear. This becomes critical in the life span of such major internal components as valve springs, wrist pins, cylinder walls and pistons.

I am a driver for Jamesport Transportation. I drive a 1998 Freightliner Century Class Condo, with a Detroit 60 series motor, the truck has 128,714 miles on it. The truck was just tuned, but it still wasn't right. I was getting a constant 5.8 miles per gallon for fuel mileage.

After we put the MotorMAX in and I ran my truck my fuel mileage increased. It did not stay a constant, with an 8000 lb. Load I received 8.2 miles per gallon fuel mileage and with a 48,000 lb. load my fuel mileage was 6.9 miles per gallon. That is an increase in mileage range of 1.1 to 2.4 miles per gallon of fuel. My temperature gauge also showed a 5 degree drop in temperature. These trucks are set with their thermostats to run at a specific temperature, so the entire temperature drop or the full effects of the MotorMAX may not be seen even when it?s doing its job. I hope this explains the results I have found with MotorMAX in my truck. If you have any questions you can give me a call. Thanks.

Reduced oil temperature: MotorMAX, by absorbing heat from internal engine parts, will also help to reduce engine oil temperatures. Reduced oil temperature results in less chance of oil breakdown, decreasing damage caused by poor lubrication. Minimizes hot spots in engines: All engines have some variance in engine temperature from front to back or side-to-side. With its ability to absorb heat and transfer it, MotorMAX reduces engine hot spots and virtually eliminates steam pockets. The ability to reduce hot spots is vital in the search for enhanced engine performance.

More comfortable passenger compartment temperatures: Now that your engine and many of its components are running cooler, the reduced temperature translates to cooler engine bay temperatures. This results in a more comfortable cab interior, with substantially increased air conditioning output in hot weather.

Reduces engine temperature rise at idle: MotorMAX will keep your water temperature lower in conditions where there is little or no airflow. With its ability to pull more heat out of the engine and into the radiator, MotorMAX helps keep your engine cooler while sitting still or at prolonged periods of high idle.

Why MotorMAX in my commercial or fleet vehicle? : Commercial or fleet vehicles are subject to particularly severe operating conditions, exposing them to above-average temperature ranges and increased life-cycle operating demands. Through reduced engine bay temperatures, additional benefits of MotorMAX include:

  • Prolonged component life
  • Reduced transmission operating temperature through cooler transmission oil temperatures.
  • Increased useable alternator amperage output.
  • Increased air conditioning efficiency, particularly critical with R-134 coolant systems.
  • More efficient fuel combustion through equalized cylinder temperatures, enhancing engine performance and fuel economy.

Easy to clean up and environmentally friendly: MotorMAX is a plant-based product that is non-toxic and biodegradable. When spilled, it is simple to clean up and presents no disposal hazards. MotorMAX is the environmentally friendly wave of the future in cooling system additives!


Racing With the MotorMAX Advantage!

Unlike traditional water wetters, MotorMAX is a natural heat sink that absorbs heat from internal engine parts and more efficiently carries it to the radiator for overall enhanced engine cooling performance.In particular, temperature differences between cylinders (hot spots) are reduced for better overall performance. Unlike many water wetters which achieve water temperature reductions by coating water jackets or speeding water flow, MotorMAX actually reduces water and oil temperatures. A true breakthrough in thermal technology, MotorMAX allows water to absorb dramatically more heat without vaporization, hence its demonstrated ability to transfer heat away from critical engine components and reduce overall engine temperatures.

MotorMAX gives racers at all levels a competitive edge across the board, including:

  • Allows reduced radiator opening for increased down force.
  • Stabilizes temperatures to prevent overheating.
  • Removes more heat from internal engine parts.
  • Reduces oil temperature.
  • Reduces horsepower-robbing engine "hot spots".
  • Reduces engine cool-down time between rounds.
  • Prevents temperature rise during reduced air flow.
  • Provides maximum performance in a 1:10 ratio.
  • Cooler engine bay and cockpit interior temperatures.
  • Easy to use. Just add to radiator.
  • pH neutral and completely safe for all aluminum and rubber components

Above all, MotorMAX is a natural plant-based product that is environmentally friendly and leaves no residue if spilled during accidents or car maintenance. MotorMAX evaporates three times faster than water, and presents none of the clean-up concerns for asphalt surfaces created by water wetters or other types of coolant system additives. MotorMAX is the perfect answer at "water only" tracks!


More Testimonials!

Our team recently began testing the MotorMAX product on our NASCAR Busch North Series car, much to our liking, I believe MotorMAX contributed to our recent win at New Thompson Speedway. We tested our cooling system on Saturday using no MotorMAX additive then performed back-to-back testing using the MotorMAX additive. What we found was a significant increase in getting the motor to a desired operating temperature and also that our running water temperatures during our long practice sessions were 5 to 10 degrees below what we are accustomed to seeing.

During our 200-lap race, I was involved in a collision with another competitor that caused extensive damage to the right front side of my Pontiac. With a limited amount of air getting into the engine compartment, I was worried that our car would be finished for the day. However, much to my surprise the addition of the MotorMAX product kept our water temperature in the normal range all afternoon. Without this product, I truly believe we would not have ended up in Victory Lane.

Our team is happy with MotorMAX and would highly recommend its use to all competitors.

Thank you for the product MotorMAX this past weekend at Riverside Park.

Riverside Park is one of the toughest racetracks for heat build-up of water temperature. During practice our water temperature was at 235 degrees, we added 2 quarts of MotorMAX and the temperature dropped to 205 degrees. Around lap 75 of the 150-lap race, our electric cooling fan stopped working. MotorMAX stood up to the rising water temperature and kept our Verres Racing #67 car at a reasonable 230 degrees thereby allowing us to continue on to a fifth place finish without any motor damage due to heat build-up.

Verres Racing will continue to use MotorMAX in our racecar and support vehicle from this point on. We, at Verres Racing, all know that ?MotorMAX? saved us costly motor damage and we do credit ?MotorMAX? for helping us to achieve our fifth place finish.


Jamie Aube, Driver
David Labbe, Crew Chief

This weekend during the Busch North event at Riverside Park we tested your product, MotorMAX.

In the sessions we ran without MotorMAX, our engine temperatures were in the 220 degree range. With the product added to our cooling system, temperatures ran in the 200 range. During the race when many suffered overheating problems, our engine ran between 200 and 220.

We look forward to continuing to use MotorMAX in the future.
