Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket fluid, manufactured by Westway Oils to meet or exceed OEM specifications for high-performance transmission and differential lubrication.

Can I mix this with my existing mineral oil?

Yes, this fully synthetic formulation is designed to be compatible with conventional mineral-based gear oils, allowing for a standard drain and fill procedure.

Is this safe for gearboxes containing yellow metals?

While API GL-5 fluids typically contain high sulfur levels, this modern synthetic formulation uses buffered EP additives to remain compatible with most synchro materials while providing maximum gear protection.
