Oil-soluble friction-reducing additive, process for the preparation thereof, and lubricating oil or fuel composition containing the additive

摘要

Additives are provided for lubricants, or fuels for internal combustion engines. They are oil-soluble aliphatic hydrocarbyl-substituted succinimide or succinamide materials, wherein the hydrocarbyl group contains about 12 to 36 carbon atoms and is preferably derived from an isomerized straight chain alpha -olefin.
