From one end of their busy season to the other, lubrication must not fail. Indifference to the choice of lubricants or a hit-and-miss policy of application will never insure reliable engine oper- ation. The most successfully and economically operated en- gines have definite standards of application and definite standards for lubrication. 75% of the engine demands on the Great Lakes can be successfully met with the Vacuum Oil Company’s famous Gargoyle Cylinder Oil 600-W and Gargoyle Voco Engine Oil No. 1. If you operate turbines or Diesels there are other Gargoyle Oils suited to these types of engines. Gargoyle Marine Oils offer you a line of oils on which you can safely standardize. These oils have made actual records of —economies in oil consumption because fewer gallons of oil are needed per year; —fewer repair expenses, due to smoother engine operation; —more power from less fuel because of reduced friction. At Lakes Ports a representative will recommend the grades of these high-grade oils “standard” for your engine. Stand- ardize for one season on these oils and check up your records of increased engine efficiency and decreased lubrication and repair expenses, A competent staff of engineers stands ready to solve your lubrication prob- lems.
