Appl. No.:

09/095825

Inventors:

Vincent M. Carey - Sewell NJ
John T. Fogarty - Mullica Hill NJ

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

C10M13510

US Classification:

Abstract:

Diesel engine cylinder oils of improved cleanliness and load carrying ability and reduced port deposit characteristics for use in marine and stationary slow speed diesel engines are based on medium heavy Group I or Group II neutral base oils, typically from 300 to 500 SUS using a liquid, oil-miscible polyisobutylene (PIB) in combination with the neutral base stock and an additive package comprising a detergent component or components, an antioxidant, an antiwear agent, and a dispersant. The detergent component preferably comprises one or more overbased phenates, phenylates, salicylates or sulfonates in order to confer the desired alkalinity characteristics on the finished oil. The oils are produced in the viscosity range of 15 to 25 cS (100Â C. ), usually with a nominal viscosity of 20 or 24 cS, i. e. , from 18. 5 to 21. 9 cS or 21. 9 to 26.

International Classification:

C10M 135/10
C10M 125/24
C23F 11/04
C10M 107/48

Abstract:

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.

International Classification:

C10M 137/10

Abstract:

A method for improving antiwear performance and demulsibility performance in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and an antiwear additive as a minor component. The antiwear additive includes a zinc dialkyl dithiophosphate compound represented by the formulawherein Rand Rare independently primary or secondary Cto Calkyl groups. The Rand Rprimary or secondary alkyl groups of the zinc dialkyl dithiophosphate compound, and the amount of the zinc dialkyl dithiophosphate compound in the lubricating oil, are sufficient for the lubricating oil to exhibit improved antiwear performance and demulsibility performance. The lubricating oils of this disclosure are suitable for use in marine system oils for two-stroke marine diesel engines.

International Classification:

C10M 141/10

Abstract:

A method for improving deposit control, while maintaining or improving demulsibility performance, in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil that has a particular phenate/carboxylate detergent mixture present in a particular amount in the formulated oil. A lubricating engine oil having a composition including a lubricating oil base stock as a major component; and a phenate/carboxylate detergent mixture as a minor component. The lubricating oils of this disclosure are useful in marine crankcase systems, in particular, marine system oil applications for two-stroke marine diesel engines.
