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.

Test Results and Assessment:


The label on this product states "RECOMMENDED FOR ALL GASOLINE AND DIESEL ENGINES OF UNITED STATES, JAPANESE, AND EUROPEAN MANUFACTURERS INCLUDING: Mack, Cummins, Man, MTY, Renault, Toyota, Volkswagon [sic], Nissan, Honda, Mitsubishi, Volvo, Mercedes Benz, Navistar, Detroit Diesel, IHC, Iveco, DAF, Scania, Fiat, PSA Specifications, when specifying API SG/CF-4."

API SG and CF-4 are obsolete specifications and are not specified by engine manufacturers for modern engines. According to the API, SG oils are not suitable for use in most gasoline-powered automotive engines built after 1993. API CF-4 oils are not suitable for use in most diesel-engines built after 1994. The label on this product fails to give adequate warning to consumers about its limited use. The organometallic additive levels in this sample indicate the product is NOT suitable for use in the majority of automobile engines currently on the road.
