Note1: Although laboratory tests alone cannot be used to establish if engine oil meets an API Service Category, they can be used to determine if it doesn't. Note2: The specification for cold cranking viscosity includes only a maximum value; the minimum value shown in the “standard” area of the chart is truncated for illustrative purposes.
