Brookfield Viscosity @-40°C mPa s (cP)

The Brookfield Viscosity at -40°C test result is slightly higher than the specification but is within the expanded range, which takes into account test reproducibility.

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 specifications for flash point and viscosity @ 100°C include only minimum values; the maximum values shown in the “standard” area of the chart are truncated for illustrative purposes.
