The owner's manual says nothing about not utilizing synthetic oils. For oil it has two notes: *2*3
*2 INFINITI recommends Genuine NISSAN Ester Engine Oil available at an INFINITI retailer.
*3 For additional information, see “Engine oil and oil filter recommendation” (P.9-6).
I have the oil changed in my coupe by my local Infiniti dealership and went to synthetic immediately. They are aware of Ester oil but don't use it there (last time I asked them about it) due to additional cost to the customer.[/quote]
Just took delivery on a 2013 G37xS and got a phone call from "Nissan/Infiniti Inner Circle" to set up a service appointment for an oil change, etc. Got me to thinking...dangerous territory!
Reading this thread, Infiniti Service Bulletin "Engine Oil Recommendation", and the manual, I am seriously considering switching to the Nissan Synthetic Ester oil and going to the "Schedule 2 (less demanding)" interval based on personal use. The dealer indicated to use non-synthetic oil, perhaps because most customers do not want to incur the higher expense of synthetics.
I see that the Service Bulletin references the 2008-2009 G37 (CV36), where I am assuming the CV36 is the engine.
Is there a oil Service Bulletin for later model G37's?
Any other guidance would be appreciated.
