My vehicle’s transmission specifies an API GL-4 gear oil. Can I use Max Gear?

My vehicle has a limited-slip differential. Do I need to add additional friction modifiers when using your Max Gear?

Yes. Max Gear is completely non-corrosive to soft yellow metals (brass, bronze, copper) so it is synchronizer-safe like a GL-4 gear oil. However, because of Royal Purple’s proprietary Synerlec additive technology, Max Gear oils retain the load carrying and shock protection capability of a GL-5 gear oil.
