Mike P: Gear lube and motor oil specifications are different. The performance requirements are based on the different applications. Lubricating gears requires different lubricant properties than lubricanting the parts inside an internal combustion engine. (One obvious difference is that sulfur is added to gear lubes but is not required in engine oils.)
The viscosity of 90 weight gear lube is similar to 50 weight motor oil. The gear lube spec is 13.5 to 24 centistokes at 100C. The motor oil spec is 16.3 to 21.9 cSt at 100C.
Hope that helps, Jim
