Which Neo to use?
I'm looking to buy a gallon of Neo synthetic lube to put in my gearbox and differential. I know it's 75w-90, but I see there are three different versions
75w-90 HD
75w-90 RHD
75w-90 EP
Which have you used?

Of those, use the HD. It's got (I believe) the lowest EP additives of the group, which means it will work best with the synchros.
I've been using that exact oil, and I'm next going to try a standard GL-4. I think the GL-5s are just too slippery to get good synchronization. Neo only makes GL-5s. Redline and Amsoil are the only synthetic makers I know with true GL-4s.

Thanks all of you for the advice. HD it is then. In real world driving I don't think there will be much difference between them ------ except for the price!
