Has anyone tried Royal purple in their AT.

Has anyone tried Royal Purple in their automatic transmission? And if so, how does it perform? I recently changed my rear differential fluid to royal purple and would like to do the same for my transmission and eventually for my motor oil. I plan on keeping my car for as long it works, I'm not the type to change cars every three years for the sake of doing it. So I try to take good care of my cars jus as my family has always done with our Infinitis'.

Bueller?....anyone?

i do. i dont notice that much of a difference, but it always feels tighter than regular and the car generally runs that way till about 2000 of the 3000 miles. fyi i have a 50500 mile 2004 at coupe.

He's not talking about the engine oil...

He was aking about the transmission. Unless you change your transmission fluid every 3K miles.

I haven't heard of anybody changing out the transmission fluid to Royal Purple. I thought about it but thought better because the Nissan fluid is designed specifically for our trannies and the dealer (of course!) didnt recommend it.
