    Abstract

    Low-temperature engine oil pumpability data have been obtained on thirteen ASTM Pumpability Reference Oils in seven full-scale test engines. Borderline Pumping Temperatures based on gallery oil pressure traces were determined for all thirteen Reference Oils in four of the test engines, and for nine of the Reference Oils in all seven test engines. Data were also obtained as to the type of flow failure occurring (air-binding or flow-limited) and on rocker arm oiling times.
