A bio-organic composition includes residues of a fatty acid glyceride-containing composition, residues of a first epoxide or glycol, and the residues of a second epoxide. The fatty acid glyceride-containing composition is characterized by the viscosity at room temperature. The first epoxide or glycol and second epoxides are present in a sufficient amount that the room temperature viscosity of the bio-organic composition is lower than the room temperature viscosity of the vegetable oil prior to formulation and/or the first epoxide or glycol and second epoxides are present in a sufficient amount that the pour point of the bio-organic composition is lower than the pour point of the fatty acid glyceride-containing composition prior to formulation.

A rubber material recovery method according to at least one embodiment of the present invention comprises a step of supplying an oil product containing a softener to a rubber material, wherein an absolute difference between a solubility parameter of the softener and a solubility parameter of the rubber material is 1.7 or less.

Disclosed is a dispersant composition, suitable for use in lubricating oils. The dispersant composition is a reaction product of (i) a polyalkenyl succinimide post-treated with a post-treating agent selected from the group consisting of an organic carbonate, an epoxide, a lactone, a hydroxyaliphatic carboxylic acid, and combinations thereof; and (ii) an acylating agent.

Disclosed herein are improved lubricating compositions effective to prevent or reduce low speed pre-ignition in an engine, as well as to prevent or reduce corrosion of engine components. The lubricating compositions include a base oil combined with a calcium chelate complex, optionally in further combination with additional additives.
