摘要： Provided are marine lubricating oils including from 15 to 95 wt % of a Group III base stock having a kinematic viscosity at 100 deg. C. of 4 to 12 cSt, 0.5 to 55 wt % of cobase stock having a kinematic viscosity at 100 deg. C. of 29 to 1000 cSt, 0.1 to 2.0 wt % of a molydithiocarbamate friction modifier, 0.1 to 2.0 wt % of a zinc dithiocarbamate anti-wear additive, and 2 to 30 wt % of other lubricating oil additives. The cobase stock is selected from the group consisting of a Group I, a Group IV, a Group V and combinations thereof. Also provided are methods of making and using the marine lubricating oils.

摘要： A functional fluid composition containing a fluid base stock (e.g., a phosphate ester fluid base stock) as a major component, and an erosion inhibitor mixture as a minor component. The erosion inhibitor mixture contains at least a first erosion inhibitor (e.g., a perhalometallate or perhalometalloidate salt) and a second erosion inhibitor (e.g., an alkali metal salt of perfluoroalkyl sulfonic acid). Erosion inhibition of the functional fluid composition is improved as compared to erosion inhibition achieved using singly the first erosion inhibitor or the second erosion inhibitor, as measured by one or more of ASTM D2624, ASTM D974, ASTM D130 and ASTM D6304. A method for operating and lubricating a hydraulic system by utilizing as a hydraulic fluid, the functional fluid composition. A method for identifying erosion inhibition effectiveness of the functional fluid. The functional fluids are useful as aircraft hydraulic fluids.
