There is provided a press-fit lubricant composition comprising an unsaturated compound with an iodine value of 100 or more.

A coating composition for forming a lubricating layer (3) on the surface of a base material (1) formed in a predetermined shape so as to exhibit improved sliding property to fluid substances, the coating composition containing, as a dispersion medium, a liquid (5) that is a component constituting the lubricating layer (3), and the dispersion medium containing solid particles (7) dispersed therein as a component constituting the lubricating layer (3). The lubricating layer (3) formed by using the coating composition exhibits more improved sliding property to fluid substances. The coating composition, therefore, can be favorably used for forming the lubricating layer (3) on the inner surfaces of the packing materials such as containers and lids.

This disclosure relates to cold cranking simulator viscosity (CCSV) boosting base stocks that allow flexibility for engine oil formulations to meet both high and low temperature viscosity requirements while maximizing fuel efficiency. The CCSV-boosting base stocks can include C28-C60 hydrocarbon materials, linear esters, tertiary amides, dialkyl carbonates, aromatic alcohols, and aromatic ethers. This disclosure also relates to lubricating oil formulations containing the CCSV-boosting base stocks, and a method for improving fuel efficiency in an engine by using as engine oil a lubricating oil formulation containing one or more of the CCSV-boosting base stocks.
