PennGrade Multi-Purpose Gear Oil SAE 80W-90

The SAE 80W-90 is formulated with high quality paraffinic base oils and a premium additive system to provide smooth, quiet performance with maximum protection against wear in gear applications. It provides superior thermal stability and minimizes oxidative sludge and varnish formations in the most severe operating conditions.

PennGrade Full Synthetic Hypoid Gear / Blower High Performance Lubricant SAE 75W-90

The SAE 75W-90 is formulated for the ultimate protection in supercharger, blower and hypoid gear applications. 100 percent synthetic, the oil is designed for use with self-contained systems where SAE 75W, SAE 80W-90 or SAE 90 grade gear oils are recommended. It is suitable for use in Roots and Lysholm Screw type superchargers and may be used in manual transmissions and hypoid differentials where high shock loading is a concern.

PennGrade Multi-Purpose 'Classic' GL-4 SAE 80W-90 Gear Oil

The SAE 80W-90 is 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 quality lubricants, use of API GL-5 lubricants with higher extreme pressure additive activity / concentration can damage these "soft" metal components.

PennGrade Limited Slip GL-5 80W-90 Gear Oil

The Limited Slip GL-5 80W-90 Gear Oil has been specifically developed to serve as a friction modified lubricant for clutch-type, limited slip differentials, reducing slick-slip "chatter" in low speed high torque operations. It is formulated with PennGrade base stocks, as well as a skillfully tailored additive system. It is recommended when an SAE 80W, 90 or 80W-90 viscosity is required.

PennGrade Multi-Purpose Gear Oil 85W-140

The 85W-140 is formulated with high quality paraffinic base oils and a premium additive system to provide smooth, quiet performance with maximum protection against wear in gear applications. It provides superior thermal stability and maximizes oxidative sludge and varnish formations in the most severe operating conditions.

PennGrade High Performance Gear Oil SAE 80W-140

The SAE 80W-140 multi-purpose, synthetic blend formulation provides smooth, quiet performance with maximum protection against wear. This all-temperature gear lubricant passes the KRL tapered bearing shear stability test and provides excellent protection to drive lines that experience heavy shock loading. Its advanced formulation technology provides superior thermal stability to minimize oxidative sludge as well as varnish formation. This product provides outstanding low temperature protection to gears and bearings. It protects against oxidation, corrosion, and foaming. The lubricant also improves fuel economy when compared to an SAE 85W-140 or straight 90W gear oil.

PennGrade Full Synthetic Hypoid Gear Lubricant SAE 75W-90

SAE 75W-90 is a specially formulated 100 percent synthetic oil designed for use with self-contained systems where an SAE 75W, SAE 80W-90 or SAE 90 gear oil is recommended. Suitable for use in Roots and Lysholm screw-type superchargers. It may also be used in manual transmissions and hypoid differentials.
