Royal Purple-->Mobil 1

I was told by the service manager that the ester oil was to help quiet things down in the engine and the only way I can see that happening is that it has to be more lubricated and I guess thats what the ester is suppose to do. 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.

When you say quiet things down are you speaking of engine slapping/knocking noise?

I just want to know what oil is best for making that slapping/knocking noise go away. I've been trying to choose between the Nissan Ester Oil and RP. My first oil change is coming up soon.

My dealer says its the injectors and all Nissan injectors sound that way.. Does that hold any truth?

Thanks!

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?

Oil is not just oil. There is a lot more that goes into making a quality oil than just petroleum. Of all things you can save money on, oil would be the last thing I would go cheap on.

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.
