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.
