Ester Oil and Engine Break-in??
I bought the service package along with my G37S but the dealer told me something that sounded questionable. They told me that the G37 uses ester engine oil, not conventional or synthetic oil. They said that the service package price includes all oil changes with ester oil (which is significantly more expensive than regular or synthetic oil) but that I may have to remind the dealer doing the service that they need to use ester oil. They said that ester oil is a new oil manufactured by Nissan and it lubricates much better than synthetic oil. I looked in the service manual and it doesn't say anything about ester oil. Was I lied to or have you guys heard something about this?
Also, I don't see anything in the manual about engine break-in. Is there an engine break-in procedure? If so, what is it?
