Test Results and Assessment:

The results of the tests conducted on this sample do NOT meet the SAE J300 specifications for the SAE Viscosity Grade listed on the product label. The Kinematic Viscosity @ 100°C is 68% lower than the minimum viscosity specification for this SAE grade, and the Low-Temperature Cranking Viscosity is sufficiently low to indicate the sample should be labeled with a lower SAE W Grade than that listed on the product label.

In addition, although the label on this product does not claim it meets any API Service Category, the test results on this sample indicates the product lacks any meaningful level of additives to protect engines from wear, sludge, and corrosion. Further, the organometallic analysis results indicate the product may contain used oil and abrasive material. For these reasons, the product is NOT suitable for use in virtually all automobile engines currently on the road.

 Use of this product in virtually all automobile engines will likely cause harm to the engine

Note: Although the results of the tests conducted on this sample meet the SAE J300 viscosity specifications for an SAE 10W-40 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.
