This method covers the laboratory determination of apparent viscosity of engine oils between -40 and 0?C and at high shear rates. The results are related to engine-cranking characteristics of engine oils. This method is an extension of ASTM D2602@ Standard Test Method for Apparent Viscosity for Motor oils at Low Temperature Using the Cold Cranking Simulator1. ASTM D2606 was developed specifically for use at -28.9?C@ -18?C@ and -17.8?C. 1Annual Book of ASTM Standard@ Part 24.
