A New Look at Multipurpose Power Transmission Fluids

Lubricant quality impacts performance and durability of heavy-duty off-highway equipment. Accordingly, equipment manufacturers work cooperatively with the petroleum and additive industries to develop performance specifications for lubricants and utilize these specifications in making recommendations for the end user. Currently, a new industry classification is being developed for multipurpose power transmission fluids. This paper discusses this proposed classification and other trends in power transmission lubrication.
