The Four Ball Wear Test can also measure the grooves and scratches caused by metal on metal contact, which allows us to measure wear and tear on metal surfaces. The longer the groove (think of a scar) produced in the steel test balls during the wear test, the greater the wear on the metal. The length of the groove (wear scar) produced during the testing of the control motor oil was .49 millimeters. Once XG’s nanoparticle infused product was added and the test was repeated, the wear scar dropped to .39 millimeters (a 25% decrease in scarring).


We wanted to see what our products were doing on the surface of the metals they were applied to, so we took apart two identical vehicles with the same mileage and sent slices of engine metal from pistons to IMR Test Labs in Lansing, New York. The two photographs below show the edges of the pistons magnified 600 times. The photo on the left is from an untreated engine. You can clearly see the divots and cavities in the metal. These are the microscopic imperfections that grind and cause friction.

The photo on the right is from the engine that was treated with XG 100. As you can see, the metal surface of the piston in this vehicle looks much different. What you are seeing is the effect of the nanoparticles on metal. The nanoparticles are so small that they fill in those cavities and imperfections, and they act as roller bearings on the surface. As the metal pistons move against each other, the outer layers of nanoparticles peel off like an onion skin, which is what causes our drastic friction reduction.
