For this program, eight lubricants were selected from three military lubricant specifications three lubricants from MIL-L2105C multipurpose gear lubricants, grades 75W, 80W-90, and 85W-140 three reference grade MIL-L2104D tactical engine lubricants, grades 10W, 40, and 15W-40 one grade OW-20 MIL-L- 46167A Arctic engine lubricant and one grade CD50 lubricant that met the MIL- L2104C specification. The lubricants were tested and evaluated under a wide range of lubrication environments using five friction-and-wear test devices. The results were analyzed by using a one-way analysis of variance ANOVA procedure. Also, a Tukey multiple comparison test was used to compare pairs of means among the gear and engine lubricants within a given test method. Lubricants were determined that had significantly different means from the other lubricants.
