Abstract: Fuel and lubricant compositions are provided that contain a primary low-speed pre-ignition (LSPI)-reducing additive comprising (i) an amino additive, (ii) an amine additive, (iii) a triazole additive, (iv) a benzamidinium additive, (v) a benzoxazole additive, or (vi) a N=C-X motif additive. Methods for preventing or reducing low speed pre-ignition events in spark-ignited engines using these compositions are also provided.

Abstract: Provided is a lubricating oil composition, for example a composition having a SAE 0W-20 viscosity grade or lower, comprising: (a) a major amount of an oil of lubricating viscosity, (b) a non-dispersant comb polymethacrylate (PMA), and (c) a non-dispersant ethylene-based olefin copolymer. Also provided is a method for reducing wear in an internal combustion engine by lubricating the engine with the lubricating oil composition.
