Abstract (en)

[origin: EP2365049A1] The use in the lubrication of a compression-ignited internal combustion engine which is fuelled with biodiesel, of a metal detergent system comprising one or more oil-soluble overbased alkaline earth metal salicylates, as an additive component in a minor amount, in a lubricating oil composition to reduce and/or inhibit oxidation of the lubricating oil composition during operation of the engine, wherein the lubricating oil composition becomes contaminated with biodiesel or a decomposition product thereof during operation of the engine.
