Abstract: Method for preventing or reducing low speed pre-ignition events in a spark- ignited internal combustion engine is provided. The method includes supplying to the engine the lubricant composition comprising a primary additive having a structure given by (I) or a salt thereof. R1 and R2 are independently H, C1 -C20 hydrocarbyl group, carboxyl group, ester, amide, ketone, ether, or hydroxyl group. R3 and R4 are independently H, C1 -C20 hydrocarbyl group, carboxyl group, ester, amide, ketone, ether, amino, or hydroxyl group or wherein R3 and R4 are part of a cyclic group. R5 is C1 -C100 hydrocarbyl group, carboxyl group, ether, or hydroxyl group. Lastly, p is 0 to 2, n is 1 to 5, m is 0 to 2, and p+n+m is less than 6.

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.
