I know some people are brand biased. Is there anyone who has any info that would prove why amsoil would be better than royal purple oil and trans fluid. Im currently using royal purple oil and trans fluid but its time to change both fluids.

I run Amsoil in all of my cars/truck tranny since I really do notice that it shifts smoother, which is important to me.
I've tried MTL from Honda, Redline MTL and MT-90 and in the RX7 -Redline MTL and MT-90 and Royal Purple and I still came back to the Amsoil Syncromesh.
The other high end synthetics are Torco and Neo Oil. Torco is used in the UAV after the US military conducted a secret durability test of the various synthetics out there. Torco didn't even know that this was going on until the winner was picked.
Neo Oil is suppose to be the most commonly used synthetic in F1 cars. And last I checked they can customize the formulation to ur specific requirements.
Id asume the data would be similar regardless of the weight of oil?
Honda White Cap. Period.
Your NSX has a wet clutch type limited slip diff. That means there are lots of small discs inside the diff that use friction to lock and unlock and are bathed in trans fluid. Only the Honda fluid has been tested to work in this environment without damage. Amsoil specifically says NOT to use in wet clutch type diffs. You will not know you are ruining your diff while driving unless 1. you open up the trans and inspect it; or 2. the diff finally fails and you lose all locking function- even then it would be hard to notice unless on a race course. So the people that run these aftermarket fluids are tootling along thinking everything is AWESOME while their diff is slowly burning out inside the gearcase. A new diff is $$$$$$. Why risk it? Use the Honda stuff.
I see what you are saying but honda cant be the only company that makes fluid for our tranny, my car/ trans has almost 100k and im just looking for something that will have added protection now that it has seen a few miles.
is this protection relative to how hard you hammer the car where the LSD needs to start to work?
Since I run 285 wide tires that are Extreme rated, it's very very hard to have wheel spin in the straights for example.
I'm trying to say what you buy will probably offer less protection than the Honda
Amsoil syncromesh trans fluid said this " Replaces Honda Genuine MTF fluid for manual transaxles and Texaco MTX fluid. Not for use in engines, hypoid rear axles, limited-slip or wet-clutch applications." So it looks like that type wont work.
I run 295's lol and havent ever spun them once
I'm with you on Royal Purple.
I'm not impressed with it at all. I think they are more interested in spending marketing $$$ on stuff like product placement in movies like Transformers, etc.
I've lost faith in Redline oil, except their SI-1 injector cleaner. That stuff is great.
