October, 1921 nn Akron Albany Atlanta Baltimore Wu IMT MARINE REVIEW tTTT'Tt't'tt"i i itt Good Ships Deserve Viking Marine Engine Oil IKING Marine Engine Oil—for V thrust bearing and reciprocating engine lubrication—is the latest development among the Sun Marine Oils. It conforms in efficiency with the high standards maintained for years in the famous Sun XX Marine Oil. Viking Engine Oil, by reason of a special patented refining process, will form a perfect and lasting emulsion with either salt or fresh water. The body of this emulsion may be varied from a heavy paste-like sub- stance to any consistency by the sim- ple addition of a larger percentage of water. For lubrication of thrust bearings an emulsion of Viking Oil with from 50 to 75 per cent water is recommended. When used for main bearings with- out the addition of water, Viking Oil has high viscosity and extremely low internal frictional values. It will absorb any water that may find its way into the bearings and will feed indefinitely through a wick without clogging the pores. Although having the saponifiable value of oils highly compounded with blown rape seed, Viking Marine Engine Oil will not. deteriorate and become rancid with age. In addition, Viking Oil is neutral in reaction and contains no fatty acids, thus eliminating the corrosion of metal parts produced by the high acid content of most marine oils. It is unaffected by low temperatures. * * * The Sun Company is one of the world’s largest producers, refiners and shippers of petroleum products.
