Test Results and Assessment:
The results of the tests conducted on this sample meet the SAE J300 specifications for the SAE Viscosity Grade listed on the product label, and are consistent with the API Service Category referenced.
Note: Although the results of the tests conducted on this sample meet the SAE J300 viscotiy specifications for an SAE 5W-30 motor oil, the viscosity declaration on the front and back labels of this product do not conform to the SAE J300 labeling requirements and those set forth in NIST Handbook 130 which state the viscosity grade must be preceded by “SAE”.

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.
