About The Petroleum Quality Institute of America

The Petroleum Quality Institute of America (PQIA) conducts independent testing of consumer, commercial, and industrial lubricants. PQIA’s mission is to serve the consumer of lubricants by testing and reporting on the quality and integrity of lubricants in the marketplace. It is expected that this improved visibility of quality will lead to wider conformance by lubricant manufacturers to specification and performance claims.

Motor Oils for Classic and Vintage Cars

The Petroleum Quality Institute of America has from time-to-time encountered motor oils containing high levels of a multifunctional oil additive called zinc dialkyldithiophosphate (ZDDP). This additive contributes anti-wear, anti-oxidation, and corrosion inhibition properties to the oil. ZDDP has been used in motor oil formulations almost universally for decades, and oils with high levels of ZDDP are often promoted as being better suited for engines in older cars with “flat-tappet” lifters.
