Cylinder Oil 600 W What Is For, What Will It Do 1920

GARGOYLE CYLINDER OIL 600 W oil (animal or vegetable oil) are more suitable than straight mineral cylinder oils. When engines are working with wet steam the advantage of using a compounded oil becomes apparent. Great care must, however, be exercised in select- ing the proper kind of fixed oil. Unsuitable fixed oils, under the action of steam and high pressure and temperature, de- compose and develop acids and a gummy residue which corrode the metal surfaces and produce a sticky, pasty, deposit which increase friction. Compounding mineral cylinder oil with the right propor- tion and quality of fixed oil usually improves its lubricat- ing properties and better results will be secured than if straight mineral cylinder oil was used without the admix- ture of fixed oil. Gargoyle Cylinder Oil 600 W is com- pounded with the proper amount of acidless tallow oil. A straight mineral oil, i.e., an oil containing no fixed oil, is necessary where the subsequent use of the condensed exhaust steam demands that it be free from oil because a straight mineral oil separates readily from water. For such purposes Gargoyle Cylinder Oil 600 W Mineral should be used. Loss by Laboratory tests to determine the per cent Evaporation °! evaPorati°n> when a sample of cylinder oil is heated to a certain temperature for a certain time, are of little value in determining the lubri- cating ( lasting”) properties of a cylinder oil, as these tests are carried out under atmospheric pressure and under con- ditions quite different from those met with in actual service. 7
