I have used both. There is no way I can tell any difference in gear oil. I just use Amsoil now because I got a local dealer and I like him and his wife.

I’ve used both and both don’t disappoint. Redline was used years ago. I’m a Amsoil guy now. Even at 30K SG is still brand new looking. This time I may push it 70K.

For gear application, i think both are great with redline may have some edge on fuel economy and amsoil may have some edge on extended oci. For transmission, redline wins hands down with their specific offering.
