A method of using lubricant compositions to reduce wear between two surfaces exposed to a load condition of at least 1 GPa is provided. The lubricant compositions comprise polysiloxane base oils having alkylaryl or a combination of alkyl and aryl functionality. The polysiloxane base oils may be defined according to the formula: wherein R, R', and R&#x2033; are independently selected, such that R is an alkyl group having between 1-3 carbon atoms; R&#x2032; is an alkylaryl group comprising alkyl functionality with 3-12 carbon atoms and aryl functionality with 6 to 12 carbon atoms; R&#x2033; is an alkyl group having between 1-3 carbon atoms or an alkylaryl group comprising alkyl functionality with 3-12 carbon atoms and aryl functionality with 6 to 12 carbon atoms; and m and n are integers, such that 8&#x3c;(m+n)&#x3c;500.

Method of reducing friction and wear between surfaces under a high load condition

A method of using energy-efficient lubricant compositions to reduce wear between two surfaces exposed to a high shear condition is provided. The lubricant compositions comprise polysiloxane base oils having alkyl, aryl, or a combination of alkyl and aryl functionality. The polysiloxane base oils may be defined according to the formula: wherein R, and R' are independently selected, such that R is an alkyl group having between 1-3 carbon atoms; R&#x2032; is an alkyl or aryl group having between 6 to 20 carbon atoms; and m and n are integers, such that 25&#x3c;(m+n)&#x3c;500 and the ratio of m/(m+n) is greater than 0.05 and less than 1.00.

Energy efficient, temporary shear thinning siloxane lubricants and method of using

A method of lubricating a wind turbine gearbox comprising using a lubricating composition comprising at least one (i.e. one or a mixture of more than one) perfluoropolyether (PFPE) lubricant which comprises a perfluorooxyalkylene chain, said perfluorooxyalkylene chain comprising recurring units having at least one ether bond and at least one fluorocarbon moiety. A wind turbine gearbox comprising a lubricating system containing said lubricating composition.
