zMAX Micro-lubricant uses the fuel, oil and transmission fluids in your vehicle to reach internal metal components. zMAX does not replace ordinary oil. Can be used in gasoline or diesel engines.

by Edward Rachanski, Chief Technical Officer, Oil-Chem Research Corp.

zMAX is added to the oil, fuel and transmission fluids. It goes beyond ordinary oil with its amazing micro-lubricating molecules that clean and penetrate areas ordinary oil can't reach. Various test engine parts were used in the following photos to illustrate the point.

zMAX Protects Against Carbon and Deposit Build-up

Even in today's modern cars and aircraft engines, carbon and other unwanted deposits can build-up in the most critical areas of your engine. zMAX kept the exhaust guide on the right virtually carbon free and dimensionally correct, while the unprotected guide on the left shows significant carbon accumulation.

zMAX Reduces Wear on Vital Engine Parts

Carbon and deposit build-up can cause valve sticking and excessive valve stem and guide wear that can lead to loss of horsepower and reduced fuel economy. zMAX helps disperse carbon and clean deposit build-up.

After initial start-up, it can take an additional 45 to 120 seconds for oil to reach critical engine parts. Starting your engine is the major cause of engine wear. The piston (left) shows severe thrust side scoring which is common when zMAX is not used. The piston (right) shows less scoring on the thrust side using zMAX.

zMAX Product Testing

Over the past 50 years, hundreds of tests have been conducted on zMAX. Many have been consumer tests using the product in everyday, real-life situations. But the important tests are the industry test protocols conducted in our own laboratory and by independent labs around the country. The results of these tests show that zMAX soaks into metal; reduces friction; increases horsepower; dissipates engine heat; helps improve or restore gas mileage and reduce emissions in older cars, by virtue of reducing engine deposits; helps maintain gas mileage and emissions in newer cars, by virtue of reducing engine deposits; helps reduce engine wear on vital engine parts, by virtue of reducing engine deposits; and helps to extend engine life, by virtue of reducing engine deposits.

zMAX spent $4.5 million testing our product to the FTC that zMAX works. The tests conducted on zMAX are based on accepted protocols as directed by the Society of Automotive Engineers (SAE) and the American Society of Testing and Materials (ASTM). zMAX requires a "soak in" period in order to achieve maximum benefit, therefore, when necessary, the protocols have been modified only to include a "soak in" period for zMAX. Oil-Chem has performed the following tests:

  • SAE J1321 - designed to measure fuel economy changes of in-service vehicles.
  • Auger Electron Spectroscopy - designed to measure the penetration of a material into a metal subsurface.
  • Modified CRC L-38 - capable of measuring bearing, cylinder, piston and valve guide wear; horsepower; piston deposits; and oil deterioration.
  • ASTM D4172 (Four Ball Method - Prevention of Wear) - designed to measure anti-wear properties of a lubricant.
  • ASTM D5182 (Four Ball Method - Coefficient of Friction) - designed to measure the coefficient of friction of a lubricant.
  • ASTM G99 (Pin on Disc Method) - designed to measure the coefficient of friction of a lubricant.
  • ASTM D2174 (Block on Ring Test) - designed to measure the coefficient of friction of a lubricant.
  • ASTM D1748 - designed to measure rust preventive properties of metal preservation.
  • Modified Sequence VIII - capable of measuring bearing, cylinder, piston and valve guide wear; horsepower; piston deposits; oil deterioration, and fuel efficiency.
  • TEOST MHT-4 Thermo-oxidation Engine Oil Simulation Test - designed to measure and emulate deposits that would occur in the piston and ring area of a modern engine.
  • FTP 75 - designed to measure the emissions of a vehicle under normal city and suburban driving conditions.
  • BAR 90 - designed to measure the in-use emissions level of vehicles for controlling air quality.

Here are several examples of how zMAX has operated on Dynamometers:

On our IRL Blueprint Racing Team with driver Jim Guthrie, we built our own Aurora V8 engines. The engines were built with zMAX in the assembly oil and was used in the motor oil on all Dyno runs.

We would conduct multiple full power runs with overnight cool down periods over a three day period. This gave zMAX time to soak into the metal and start working. After the third day, we were obtaining an additional 6 horsepower.

When at the track and after running the car for the day, we would bring the car into the pit and remove all the spark plugs.

We would then spray zMAX into each spark plug hole and bump the motor over so zMAX would coat the cylinder walls, pistons/rings and then let the metal cool overnight. The performance of zMAX in our race engines achieved better consistency over time.

Our engine performance maintained it's baseline to a very high degree throughout the complete race as evident from the engine leak down numbers which were shown to be consistent from pre- to post-race inspection.

These Hot & Cold procedures help massage zMAX into the metal so it's Micro-Lubrication action becomes effective.

On our Labeco Single Cylinder Engine Test Stand, multiple Sequence VIII test's without and with zMAX (A vs B comparison) were performed. Both protocols utilized a five day Pre-Soak-in period before the testing began.

The engine was operated for one hour followed by a six hour cool down period. The engine was then operated for one more hour at the end of the work day.

zMAX's ability to soak into and "Micro-Lubricate" metal provides better lubricated and cooler working surfaces. zMAX provides improved Valve and Piston/Ring-Cylinder Wall sealing which has a positive effect on better Combustion Chamber Performance.

Better Combustion Chamber Sealing has a direct effect on achieving better Horsepower, Torque and Improved Fuel Mileage with Lower Emissions.
