Abstract
Lubricant field problems due to diesel engine soot have been reported in stop-go vehicles in Europe and the U.S. Soot generated in these vehicles can cause heavy-sludge, high lubricant viscosity increase, or oil gelling.
In field and dynamometer testing, the authors demonstrate that certain oil formulations minimize these problems. Oils labeled CD/SF/EO-K produce significantly different soot dispersancy and viscosity control. In addition, formulations which provide adequate soot dispersancy also reduce engine wear.
