Abstract: In order to rapidly select the best lubricating grease for vehicles in different conditions, 4 actual vehicle working conditions are simulated including normal driving, heavy load, climbing and high speed using a four-ball machine with the wear diameter of the measured sample as evaluation index. Combined with droplet point, evaporation loss and oxidation stability, the performance of 4 long-life composite lithium based grease is studied, and the best choice of lubricating grease under different using scenarios are summarized as well.

Key words: Long-life, Actual working conditions, Lubricating grease, Wear scar diamete
