Test Results and Assessment:

The label on the product tested does not comply with the Fair Packaging and Labeling Act (FPLA), or the Uniform Packaging and Labeling Regulations, each of which require the product label to include a declaration of responsibility (name and address of manufacturer, packer, or distributor) of the product.

The front label on this product states "5-30” in large print which could be interpreted by a consumer as meaning it’s an SAE 5W-30 viscosity grade. The product does NOT, however, meet the SAE J300 specifications for an SAE 5W-30 motor oil. In addition, although the front label states "PREMIUM," the test results on this sample confirm the statements on the back label of the product that “It contains little to no additives. It is not suitable for use in most gasoline powered automotive engines built after 1930. Use in modern day engines may cause unsatisfactory engine performance or equipment harm.” Based on these statements, test results, and product labeling, consumers are advised not to use this product in virtually any car currently on the road.

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.

  1. Standards, shown in yellow are established by API, SAE and others.
  2. Test Method for metal analysis is ASTM D5185.
  3. This specification is expressed to two significant figures, therefore results up to 15.5 are considered on specification.
  4. This specification is expressed to one significant figure, therefore results between 550 and 849 are considered on specification.
