Book Description

Excerpt from American Lubricants: From the Standpoint of the Consumer The purpose of this book is to aid the user and the buyer of lubricants in a more intelligent selection of oils and greases. The point of view throughout is that of the user rather than that of the refiner. An effort has been made to include such facts and figures in regard to lubricants as will best serve to bridge the gap between the refiner or manufacturer and the consumer. Of almost equal importance, a conscientious effort has been made also to exclude irrelevant matter so as not to obscure the main facts. In a book of this character it is of the utmost importance that the refiner, the seller, the buyer and the user of lubricating oils speak the same language. The language of the American oil trade, so far as viscosity is concerned, is that of the Saybolt Universal Viscosimeter; consequently all viscosities given in this book are with this viscosimeter at 100 F. unless otherwise specified, except that the viscosity of cylinder oils is taken at 210 F. Likewise the Flash and Fire Tests are with the Cleveland (or similar) Open Cup. Unless otherwise stated, all temperatures are Fahrenheit, and the Baume gravity is based on the Bureau of Standards scale at 60 F. The specifications given are in all cases the latest obtainable. The author takes this occasion to acknowledge his indebtedness, directly and indirectly, to the published data on petroleum oils which has been drawn upon freely. He trusts that the book will prove of practical aid, especially to the buyer and the consumer of lubricants.
