| 4 Naturally, the element of abrasiveness, must be as low as possible and change as little as possible during use. This, of course, also applies to the EP{G. Eric Platford - Chief Quality Engineer} value or load capacity of the lubricant. One rule which the user of EP{G. Eric Platford - Chief Quality Engineer} oils can follow, and in this I am also including those who have to do with the lubricating service, is to use the lubricant recommended by the manufacturer of the particular car. I am positively certain that the car manufacturer has a better chance of knowing more accurately than anyone else what lubricant is most suitable for his axle and if his recommendations are followed the best results will be obtained. Much can, of course, be said to the manufacturers and distributors of hypoid lubricants. I am sure that if the producers and the distributors will put forth as much effort to build satisfactory lubricants as the car manufacturers have to build fine mechanical units for axles that the problem facing us now will not be concerning the types of lubricants but rather, their individual properties and the poor attempts to make EP{G. Eric Platford - Chief Quality Engineer} lubricants with the resulting poor product will be eliminated. There are some very good hypoid lubricants. There are many who are earnestly endeavoring to produce good lubricants and for those there is no criticism. - 13 - | ||
