Provided is an engine oil lubricant composition with improved fuel efficiency. The engine oil lubricant composition may include: a polyalpha olefin base oil component an amount of about 50 wt % to about 90 wt % based on a total weight of the engine oil lubricant composition, wherein the polyalpha olefin base oil component is a Group IV base oil and has a Noack volatility of about 12.5% to about 15%; a Group II base oil component in an amount of about 0.1 wt % to about 50 wt % based on the total weight of the engine oil lubricant composition. The engine oil lubricant composition may have (i) a kinematic viscosity at 100? C. of about 10 cSt or less, (ii) a high temperature high shear viscosity at 150? C. of about 2.2 cP or less, and (iii) a Noack volatility of about 20% or less.

[Problem]

Provided is an operating oil for shock absorber in which influences against rubber materials are controlled.

[Solution]

An operating oil coming into contact with a rubber material, the operating oil containing a polyalkylene glycol and at least one base oil selected from a fatty acid diester, a poly-alfa-olefin, and a lubricating oil classified as GIII in American Petroleum Institute (API).

[Effect]

According to the operating oil, in view of the fact that swelling properties of a rubber material, such as a seal material, etc., are reduced, conventionally used rubber materials can be used without being changed.

A composition and method for reducing the coefficient of friction and required pulling force of a wire or cable are provided. A composition of aqueous emulsion is provided that is environmentally friendly, halogen free and solvent free. The composition is compatible with various types of insulating materials and may be applied after the wire or cable is cooled and also by spraying or submerging the wire or cable in a bath. The composition contains lubricating agents that provide lower coefficient of friction for wire or cable installation and continuous wire or cable surface lubrication thereafter.

Compositions and devices are provided that provide a persistent low-friction coating on a solid surface, by application of a mixture of a polyethylene glycol-containing surfactant and a vegetable to the surface. The coating thus generated does not require replenishing during use and persists through rinsing and multiple uses. Surprisingly, markedly reduced friction is found when the surfactant is provided at 3% w/v to 7% w/v in the composition. Such compositions and methods are suitable for application to both mixing and separation operations. Formulation of such compositions with food grade components permits use in food processing.

A method for improving fuel efficiency and reducing frictional properties while maintaining or improving deposit control, in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including from 75 to 95 wt % of lubricating oil base stock including a Group I base stock or a combination of a Group III, Group IV and Group V base stock including from 30 to 35 wt % Group III, 45 to 55 wt % Group IV and 0 to 5 wt % Group V and a friction modifier mixture comprising a polymeric ethoxylated fatty acid ester at from 0.1 to 1.0 wt. % and a mixed glyceride ester at from 0.1 to 1.0 wt. % of the formulated oil. The lubricating engine oils are useful in internal combustion engines including direct injection, gasoline and diesel engines.
