Super S GL-4 EP Gear Oil SAE 90 is a mineral based lubricant that is used in automotive and heavy duty manual transmission and gear applications. GL-4 rated gears oils have  extreme pressure additives and provide excellent load carrying capabilities. They are used in extreme service applications and contain oxidation, rust and corrosion inhibitors, anti-foam agents and pour point depressants. SAE 90 represents the thickness of the oil which equates to an International Standards Organization Viscosity Grade (ISO VG) 220 as well as an SAE (Engine) 50 weight.
