摘要：
Disclosed is a lubricating engine oil composition comprising a lubricating oil base stock as a major component, and at least one metal or metalloid hydrogen atom donor compound. Also disclosed is a method for preventing or reducing low speed pre-ignition in a direct injected, boosted, spark ignited internal combustion engine, and the use of at least one metal or metalloid hydrogen atom donor compound in a lubricating engine oil composition for preventing or reducing low speed pre-ignition in a direct injected, boosted, spark ignited internal combustion engine.
