interesting read but it sounds like it would be good to use 100% lucas oil so it sticks to the gears and not trap air or just stay away from the Lucas oil all together?
I have noticed smoother transitions though after switching gears. Maybe the 80%RP and 20% lucas was a good mix?
Might end up changing out to 100% royal purple depending on replies
Edit: actually nvm, just read some posts on how RP and Lucas are lower rated gear oils. I'll be changing out the diff. fluid tomorrow with Amsoil when I find a store with some.
Anyone know what stores sells them? Seems like autozone and napa don't carry Amsoil
