Abstract

Additive packages for engine oils were prepared using PIB-succinimide combinations with different properties. PIB-succinimide-type dispersants of various average molecular weights and dominant side effects were selected for preparing multifunctional additive combinations. A high-molecular-weight PIB-polysuccinimide type as viscosity-index improver, a PIB-polysuccinimide with strong basic character as a highly effective sludge dispersant, molybdenum-containing polyalkylene-polysuccinic anhydride derivatives as dispersants with complementary antifriction efficiency, and some conventional detergent, antioxidant, antiwear, and anticorrosion engine oil additives were used in engine oil compositions of various viscosity grades. The technical and economic advantages of appropriately selected and balanced additive combinations were shown by bench test results of the rheological, detergent-dispersant, and antifriction properties of the test oils.
