Overview
Lubricating oils are used in machinery to reduce friction between two surfaces in contact. The improper selection of a lubricant can result in wasted energy due to heat loss and premature wear of parts. Lubricating oils are generally classified into two categories, refined and synthetic. Refined oils are produced from the refinement of existing petroleum or vegetable oils and synthetic oils are produced from chemical synthesis. Synthetic oils are much more expensive than refined oils, but provide lower pour points, lower coefficients of friction, better oxidation stability and a better viscosity index.
In this course, the student will learn the basics of lubricating oils including how they are manufactured and the relative merits between different types. The course will cover Chapter 3, "Lubricating Oils" and Chapter 7, "Lubricant Additives" in the US Army Corps of Engineers document EM 1110-2-1424, "Lubricants and Hydraulic Fluids".
The student must take a multiple-choice quiz consisting of ten questions at the end of this course to obtain PDH credits.
