The use of (a) one or more trinuclear molybdenum compounds; and/or (b) one or more molybdenum dithiocarbamate and/or dithiophosphate compounds other than those defined in (a), in a diesel engine lubricating oil composition to control soot induced viscosity increase of the composition. The molybdenum compounds are also useful in controlling wear in the diesel engine and extending the drain interval of lubricating oil compositions.
La présente invention concerne l'utilisation (a) d'un ou plusieurs composés trinucléaires au molybdène et/ou (b) d'un ou plusieurs composés au dithiocarbamate et/ou dithiophosphate de molybdène autres que ceux définis en (a) dans une composition d'huile de lubrification pour moteurs diesel destinée à lutter contre l'augmentation de viscosité de la composition induite par les suies. Ces composés au molybdène conviennent également pour lutter contre l'usure des moteurs diesel, et à étendre l'intervalle entre vidanges de compositions d'huile de lubrification.
