Ester Oil for New 3.5.

[PbLead]

Nissan has reccomended and put in from the factory Ester Oil. I'm informing you of this so that when you change your oil and put in petrolium based oil or even synthetic you run the risk of engine noise. Specifically because Ester Oil clings to the parts as regular and synthetic do not. It is expensive but is reccomended. Nissan has also made this fact clear for the 370Z.

It is recommended but not required. I just had my oil changed at the Nissan dealership and the recommended the Nissan synthetic or Mobil 1 synthetic. I have not had any engine noises.

thats a bunch of crap, only thing i did hear about making noise is the use of non oem filter but thats it. why pay 12 dollars when u can get about 2 qt for that price hell with that ester oil. and i actually went with synpower and it its pretty good for valvoline, someone just recently told me that the 5w30 from mobile 1, well they changed the formual and its not as good.

Valvoline recommended their SynPower 5w-30 for this application.

Pennzoil told me they'd fully back their full synthetic products (Platinum or Ultra) for applications requiring the ester oil.

Here is what their e-mail to another person who asked:

Thank you for your interest in our products.
It has come to our attention that certain 2009 Nissan and Infiniti vehicles require a special "ester" motor oil. Upon further investigation, Nissan's requirement is for organic, friction-modifiers in the oil to provide lubrication for Diamond-Like Coated (DLC) engine parts. Esters are a class of organic friction modifiers that provide the performance needed to protect these coatings and engine surfaces. Nissan's general recommendation is for SAE 5W-30 engine oils in these vehicles.
The Pennzoil Ultra 5W-30 oil uses the organic friction modifiers and are recommended for Nissan and Infinity vehicles requiring"ester"
motor oil.
Sincerely
