NEED FOR SIMPLIFYING RECOMMENDATIONS OF TRANSMISSION AND REAR AXLE LUBRICANTS 370026
Since the publication of the original Classification of Transmission and Rear Axle Lubricants back in 1931, evolution has seen the development of a most complicated and varied number of gear lubricant recommendations for the millions of cars now on our highways.
Each year as new features are introduced, changes are made which affect gear lubricant requirements of the past. Yet nothing is done to revise car manufacturers' lubrication charts made up previously each year. A composite grouping of gear lubricants would simplify the servicing of cars on the road.
At the present time, the service station attendant is required to follow with exactness lubrication charts for each and every make and model of car if he would keep the car owner out of trouble. On the other hand, the service station needs are best filled by the smallest number of grades required for proper servicing since large inventories and especially gear lubricant dispensing equipment (metered) are costly.
Tests and practical experience have shown that economy and satisfaction can be effected with stable non-corrosive mild E.P.'s for all transmissions of the conventional, overdrive and free-wheeling types as well as for all rear axles other than Hypoids--the latter requiring active powerful Hypoid gear lubricants.
