Beschreibung
Zusammenfassung:	Soot induced kinematic viscosity increase of lubricating oil compositions for diesel engines, particularly heavy duty diesel engines, equipped with EGR systems, particularly EGR systems operating in a condensing mode, can be ameliorated by addition of a phenylenediamine compound. La viscosité cinématique induite par la suie de compositions d'huile librifiante pour moteurs diesels, en particulier pour moteurs diesels d'engins lourds, équipés de systèmes à GRE, en particulier des systèmes à RGE fonctionnant en mode condensation, peut être améliorée en ajoutant une phénylènediamine.
