Zusammenfassung:	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 byor 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.
