Mileage 365 10-40

Although the label on this product does not claim it meets any API Service Category or SAE Viscosity Grade (or any other specification for that matter), 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 levels of silicon, copper, and iron in the product indicates it may contain used oil and abrasive material. For these reasons, the product is NOT suitable for use in automobile engines.

In addition, the front label on the product prominently displays "10-40.” This could be interpreted by a reasonable person to mean the motor oil is an SAE 10W-40 viscosity grade, which it is not. Although the back label of the product states “10-40 means a motor oil with a viscosity ranging from 4.4 cSt to 14 cSt @ 100° Celsius," this viscosity range is not consistent with any multi-viscosity motor oil as defined by SAE J300.

Note: The label on this product does not show the name or address of the manufacturer, packer, or distributor. This information is required to comply with the Uniform Packaging and Labeling Regulations in NIST Handbook 130 which states "Any package kept, offered, or exposed for sale, or sold at any place other than on the premises where packed shall specify conspicuously on the label of the package the name and address of the manufacturer, packer, or distributor. The name shall be the actual corporate name, or, when not incorporated, the name under which the business is conducted.  The address shall include street address, city, state (or country if outside the United States), and ZIP Code (or the mailing code, if any, used in countries other than the United States); however, the street address may be omitted if it is listed in any readily accessible, well-known, widely published, and publicly available resource, including but not limited to a printed directory, electronic database, or website."

Note: 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.
