The Petroleum Quality Institute of America (PQIA) is an independent resource for information and insights on the quality of lubricants in the marketplace. Our mission is to serve the consumer of lubricants by randomly sampling and independently testing lubricants taken from the field. Test results are posted along with the brand names on the PQIA website. This webpage provides an analysis on the brand detailed below.
The following are the test results for the sample examined.
Marketed by: DOLGENCORP, LLC.
Purchased at: Middlesex, NJ
Date of purchase: 6/11/2015

The results of the tests conducted on this sample meet the SAE J300 specifications for the SAE Viscosity Grade listed on the product label, and are consistent with the listed API Service Categories.
Note: The back label on this product lists API Service SA which is an obsolete specification not intended for engines built after 1930! According to the API, this service category of oil is unsuitable for most gasoline engines built thereafter and may cause harm to modern engines. To their credit, the back label includes a cautionary statement about the product's limited use.
