Cold Starting and Pumpability Studies in Modern Engines — Results from the ASTM D02.07C Low Temperature Engine Performance Task Force Activities: Background and Organization


In response to a request by SAE, the Low Temperature Engine Performance (LTEP) task force was established within Section 7C in 1992 to determine the starting and pumping characteristics of modern engines using multigrade and single-grade oils, determine if there existed a “safety margin” between limiting cranking and pumping viscosities in modern engines, and assess the benefits or limitations of current lab tests for identifying oils which could result in pumpability failures in engines. This paper discusses the background surrounding the activity and the organization of the task force.
