This is always comforting:

"According to the FTC, the CRC L38 test is a standard auto industry tool to measure the bearing corrosion protection properties of motor oils. In February/March 1997, an independent laboratory performed two CRC L38 tests of zMax for Speedway and Oil Chem. In those tests, motor oil treated with zMax produced more than twice as much bearing corrosion as motor oil alone."
