But I just put in royal purple and have a couple hundred miles on it and I notice no difference in engine noise. Its loud to begin with.
That's not the engine noise they're talking about. It's not engine "loudness" that the Ester oil helps with, there is an issue with valvetrain noise (clatter) in some VQ37 engines - according to a Nissan TSB (it's posted here on the site somewhere) the Ester oil is a "cure" for that valvetrain noise. Capisce?

M1 is good but I prefer Redline mainly because its formula is ester based. So far, so good but i only have 6800 miles, and 1800 miles on the redline.
