Test Results and Assessment:

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

Mileage 365 5-30

Although the label on this product does not claim it meets any API Service Category (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 "5-30.”  This could be interpreted by a reasonable person, or even a convenience store wholesale distributor, as shown by example here, to mean the motor oil is an SAE 5W-30 viscosity grade, which it is not. Although the back label of the product states “5-30 means a motor oil with a viscosity ranging from 4 cSt to 12 cSt @ 100° Celsius," this viscosity range is not consistent with any multi-viscosity motor oil as defined by SAE J300.

The product label also fails to display the name of the manufacturer or contact information. Such information is required to be shown on retail products in most states.

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.
