Provided is a grease composition which can be used as a lubricant for roller bearings, exhibits excellent high temperature durability and rust preventive property, and can prevent premature flaking on the rolling surface due to hydrogen embrittlement. A roller bearing 1 is obtained by sealing a grease composition 7 in the periphery of a rolling element 4, this grease composition 7 is composed of a base oil excluding an ester-based synthetic oil, a thickener, and an additive, the additive contains (a) an alkanolamine and (b) 2,2,4-trimethyl-1,2-dihydroquinoline or a polymer thereof but does not contain an organic sulfonate, and (a) and (b) are contained at from 0.1 to 10 parts by weight with respect to 100 parts by weight of a total amount of the base oil and the thickener, respectively.

A fluid contains a base oil consisting of an alcohol-initiated polyalkylene glycol where polyalkylene glycol component is selected from a homopolymer of 1,2-butylene oxide and copolymer of 1,2-butylene oxide and propylene oxide; a glycerol-initiated unsaturated ester that is free of tertiary carbon atoms and quaternary carbon atoms; and an antioxidant.

To provide a composition for a heat cycle system, which comprises a working fluid for heat cycle which has a low global warming potential and high stability, and which can replace R410A, and a heat cycle system employing the composition. A composition for a heat cycle system, which comprises a working fluid for heat cycle containing trifluoroethylene, and a stabilizer for preventing deterioration of the working fluid for heat cycle, such as an oxidation resistance-improving agent, a heat resistance-improving agent or a metal deactivator, and a heat cycle system employing the composition for a heat cycle system.

A method for improving oxidative stability of a lubricating oil in a diesel engine, in which biodiesel fuel is used with diesel fuel in the diesel engine, by using as the lubricating oil a formulated oil. The formulated oil has a composition including at least one Group V lubricating oil base stock. The at least one Group V lubricating oil base stock is present in an amount from 1 to 75 weight percent, based on the total weight of the lubricating oil. Oxidative stability is improved in a diesel engine lubricated with the lubricating oil, as compared to oxidative stability achieved in a diesel engine lubricated with a lubricating oil not having the at least one Group V lubricating oil base stock, as determined by a CEC L-109-16 Bio-Diesel Oxidation Bench test. The lubricating oils are useful as passenger vehicle engine oil (PVEO) products or commercial vehicle engine oil (CVEO) products.
