I'm rebuilding an older Chevy shifter. I have plenty of Amsoil lube grease, and was wondering if it would be better to lube the shifter with this over white lithium? The shifter is all metal parts, and is exposed to the ground. I know you don't mix greases, so I'd be using the lube grease anytime it needed it. Somebody in a past-post suggested using Amsoil Heavy Metal Protector, but that seems a little light duty for me...Any thoughts... Thanks.
