The test can also be skewed depending on how you perform the test. Knowing how moly interacts with pressure and wear surfaces, it takes anywhere from say 30 seconds to five minutes for moly to form a new wear surface consisting of "glassy plates" when then are sacrificial. Depending on the pressure exerted on the torque arm and how fast the load is applied, this will affect the amount of moly wear film and it's load bearing capacity.
Excellent! Thanks, Charles. You da man when it comes to oils! Do you have a link to the retraction?
