PennGrade - SAE 80W-90 Classic Gear Oil

PennGrade - SAE 80W-90 Classic Gear Oil

Specially blended using high quality PennGrade mineral base stocks and select additive technologies. It is designed to be used with “yellow” metallurgy (brass, bronze, copper) and with “soft” metals used in synchronizers, bushings, thrust washers and other components typically found in classic manual transmissions and transaxles. In applications specifying API GL-4 lubricants, the use of API GL-5 lubricants can damage these “soft” metal components.Â
