Abstract
Recent examples of sludge incidence in vehicles operated on API SF, SF/CC and SF/CD category oils in both severe duty and normal consumer service from Europe and North America are presented. A comparison of the chemical and morphological characteristics of sludge taken from these vehicles is summarized, as are the sludge-preventing capabilities of various North American and European reference oils.
The design and execution of a series of oil formulation understanding programs aimed at evaluating the influence of viscosity modifier chemistry, viscosity grade and various detergent inhibitor package variables on sludge deposit prevention in the M102E and PV-2 (Sequence V-D replacement) engine tests being developed by CEC and ASTM, respectively, is presented.
The knowledge derived from these formulation programs is used to develop prototype technologies designed to meet the requirements of Volkswagen 501.01 specifications for black sludge inhibition and the proposed API PS-3 (SG) category and Daimler Benz P.226.3.
