Test Results and Assessment:

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

Q Motor Oil® 10•30
Q Motor Oil® is a Registered Mark of Conatus Oil & Gas, Inc

Whereas the label on this product states "10•30” in large print (which could be interpreted by a consumer as meaning it’s an SAE 10W-30 viscosity grade), the label also states in smaller print “Viscosity Range 10 To 30*.” This terminology is not consistent with any multi-viscosity motor oil as defined by SAE J300.

In addition, 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 metal 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. Similarly, although the back label on the product states “Suitable for Moderate Diesel Engines,” use of this product in virtually all diesel engines currently on the road will likely cause harm to the engine.

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.
