LOW VISCOSITY MARINE CYLINDER LUBRICATING OIL COMPOSITIONS

摘要

Disclosed herein are marine cylinder lubricants which comprise a major amount of basestock selected from the group consisting of a Group II basestock, a Group III basestock and mixtures thereof, wherein the marine cylinder lubricant has a kinematic viscosity at 100° C. of from 13 to about 16.2 cSt, and contains less than about 10 wt. % bright stock. Also disclosed are marine cylinder lubricants which comprise a major amount of basestock selected from the group consisting of a Group II basestock, a Group III basestock and mixtures thereof, wherein the marine cylinder lubricant has a kinematic viscosity at 100° C. of between about 13 and about 16.2 cSt: and a total base number of 5 to about 70, and further wherein the marine cylinder lubricant contains less than about 10 wt. % bright stock.
