PETROLEUM QUALITY INSTITUTE OF AMERICA TEST PROGRAM
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. 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.
