This paper presented the study on the characteristic of surface contacted friction according to ASTM of some kinds of commercial lubricants with the same viscosity index, during the work at different temperature conditions. The results showed that there were significant changes in the friction characteristics following the temperature of lubricants with equivalent viscosities. Changes in lubricant friction characteristics decided the wear resistant ability and longevity of the working friction pair. Therefore, choosing lubricant according to the viscosity index was not sufficient. It must also be based on the lubricant friction characteristic to ensure the longevity and reliability of the lubricated friction pair.
