Designed for vehicles and equipment specifying API GL-4, it mixes with branded gear oils but performs best when used alone. The formulation prioritizes wear reduction, excellent lubrication properties and strong corrosion protection to keep gears operating smoothly under everyday and demanding conditions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat types of gearboxes and drives can this oil be used in?\u003c\/h3\u003e\n\n\u003cp\u003eUse this GL-4 oil in manual transmissions, axle drives and other gear systems where the manufacturer calls for API GL-4 performance.
