Xtreme SAE 90 Gear Oil is a premium, high-viscosity mineral lubricant essential for transmissions and industrial gearboxes where non-Extreme Pressure (non-EP) gear oils are specified. This 1 gallon jug of GL-1 rated oil is formulated with high-quality base stocks and foam inhibitors, providing a thick, hydrodynamic film that protects metal components from wear under normal loads. It’s the right choice for older equipment, manual transmissions, and certain industrial gear reducers that contain brass or bronze synchronizers or bushings, as it lacks the corrosive EP additives found in GL-4 and GL-5 oils. This reliable oil ensures smooth operation and excellent heat transfer, helping to extend the life of your equipment.

It is absolutely crucial to verify that your equipment specifically calls for an API GL-1 or non-EP gear oil before using this product. Using a GL-1 oil in a modern differential (which almost always requires GL-5) will lead to rapid gear failure due to lack of adequate protection. Conversely, using a modern GL-4 or GL-5 oil in an older gearbox that requires GL-1 can corrode the soft brass or bronze components. Always check your owner’s manual; if it specifies GL-1, this is the correct, trustworthy lubricant for the job.
