Abstract

A new low molybdenum and sulfur containing PIB-polysuccinimide type dispersant additives were studied in two engine oil compositions. The possibility of the total or partial replacement of the conventional dispersant and also the possibility of the reduction of ZnDDP were investigated. The detergent-dispersant effects strongly depended on the composition and the type of the package. Using the combinations of the conventional and the molybdenum and sulfur containing PIB-polysuccinimides, the properties of the reference packages could be achieved. The experimental dispersant had significant antioxidant effect. A thermal pre-treatment proved to be advantageous to the AF/AW efficiency of the experimental engine oils. Using the new molybdenum and sulfur containing dispersant additive, the ZnDDP level could be reduced in the engine oils. This may open up an opportunity for formulating environmental compatible engine oils. This is an abstract of a paper presented at the 15th International Colloquium Tribology - Automotive and Industrial Lubrication (Ostfildern, Germany 1/17-19/2006).
