THE PROBLEM OF CYLINDER WEAR.
It is a commonplace that the life of an internal combustion engine can be made or marred during the vital period of running-in. But keeping down the engine speed for the first thousand miles, beneficial though it is, can be made to preserve the cylinder walls and working surfaces still more effectively if the lubricating oil contains colloidal graphite.
Just why this should be so is explained with great lucidity by Dr. A. H. Stuart in a little booklet called” The Running-In of Internal Combustion Engines,” and issued by Messrs. E. G. Acheson, Ltd., Of Thames House, Millbank, London, S.W. 1. The reader is taken safely through the most intricate paths of lubrication theory and practice, and no one can fail to glean useful information from a perusal of the text and accompanying illustrations. Although the primary purpose is, of course, to point out the value of a colloidal graphite running-in compound, the whole process of lubrication is fully explained. Definitely a booklet to study.
