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.

Test Results and Assessment:

The results of the tests conducted on this sample are NOT consistent with the API Service Category listed on the product label. This product is labeled as API Service SA which by definition should contain no additives. The metal analysis results for this sample indicate the product does contain some additives. In addition, the labels fail to give adequate warning that the API Service Category listed on the product label is OBSOLETE and is not suitable for use in most gasoline-powered automotive engines built after 1930. Use in more modern engines may cause unsatisfactory performance or equipment harm.

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.
