Roll ’em Aboard! There’s more Lubricating ability inevery barrel—and far less Carbon. In the operation of the Diesel En- gine, where lubrication must be posi- tive and uniform, this is important; because any oil that forms hard car- bon will produce high temperatures, destructive wear and loss of power. TEXACO URSA OIL for Diesel Engines is pure and unblended. And because it contains no paraffine, leaves a sur- prisingly small amount of carbon; and that soft and fluffy. Many of the world’s Navies and Merchant Marines who are now using TEXACO URSA OIL highly praise its small carbon content and its de- pendable and economical lubricating qualities. We, on our part, are so certain of the superiority of “URSA” for Diesel Engine lubrication that we earnestly entreat you to try it. No matter what port you buy it at, each barrel of TEXACO URSA OIL will be found to be the same pure, clean, dependable lubricant for Diesels. And remember: There is a Texaco lubricant for every purpose aboard ship. We invite your inquiry regarding any Texaco Marine Lubricant and extend the fullest co- operation of our Engineering Department.
