Ester refers to a synthetic blend of oil that has certain high end lubrication properties. Don't know where the name "Ester" came from.
Infiniti has a technical bulletin addressing this. Apparently "ester" oil was shipped in the vehicles from the factory, but at the 1st oil change after purchase, non-ester oil was used. Hense the valvetrain noise. The problem was identified and the the fix was the reintroduction of ester oil.

congrats on your new car it looks great. can you tell me if the 09 trunk has an obstructed trunk opening due to the nav/cd system? i know the 08's did and it made a small trunk even smaller. what did you end up paying? i'm sure there not offering the 0.9 financing like the 08's have.

Let's clear up a few things here. The Nissan Ester oil is NOT a synthetic blend. It is conventional 5W-30 oil. According to the European Patent Application for this oil available on the web and referred to in a number of other G37 forums, the claims for this oil are that the carbon-based additives increase fuel economy. According to the Infiniti VVEL Technical paper, the carbon-based additives reduce friction across the VVEL valve stem diamond-like carbon coating. That seems to be the gist of the Nissan Ester oil.
Esters are PAO based substances added to oils and lubricants. Based on the European Patent Application, the Nissan Ester oil does not seem to have additional esters or greater quantities of esters.
Are you referring to the "out-of-sync" VVEL Technical Service Bulletin? If so, the newer software seems to be the key to getting the VVEL to return to idle, even though the amended TSB calls for an Ester oil change after updating the software.
Nissan has only recently stated the Ester oil is a factory fill. Most people with Ester factory fill may not have even performed their first oil change yet. The "change" from Ester to non-Ester oils does not appear to have any effect on the valve train noise you refer to. And, I am not sure what noise, exactly, you are referring to. The "identified" problem is the VVEL software which does not return the valve timing to idle setting after the car has been driven hard. The updated software is the "cure" for the out-of-sync VVEL knocking. Unless a different "noise" could be caused by the valve stem diamond-like coating, and the Ester carbon-based additive is the only way to the quiet this noise, then the cure is not the Ester oil.
This information is all available elsewhere on the net.

Thanks for the great response.
Has your G37 been updated with the software referred to?
I am using Mobil 1 synthetic. From what I have read this oil does have the Ester properties.

Wow. Talk about information overload. That which I presented came from the retailer. However, your feedback is more plausible. I will check with the service advisor to see if he is aware of what you have revealed here.
Thanks for the additional material.

Does anyone with a G37 have the new Palm Pre? If so, how does it work with the Infiniti Bluetooth system and does the mp3 integrate like an iPhone?
(The Bluetooth site at Infiniti indicates it is being tested but makes no recommendations pro or con.)

I have the Palm Centro, which probably has a similar Bluetooth interface to the Pre (but I'm not certain). It works fine, but the biggest problem is that it cannot answer calls. (It recognizes when the phone rings and appears to let you pick up, but the call gets dropped; if you answer directly on the phone, however, it works fine.) It also doesn't display the number/ID of the caller, which is all the more reason to pick up your phone and look. It's not perfect, but the hands-free operation otherwise works well (much better voice quality than on the Acura TL, from my experience).
You could use any MP3 player via the aux input, but you wouldn't have control over the songs/menu the same way you do with the iPod.

Well, I got the Palm Pre and not only does it work, but I can answer calls and the caller i.d. comes through . The only thing it didn't do was automatically download the phonebook . That had to be done manually.

Mine works too however the sound is scratchy and not as clear as my previous Samsung.
How is your sound clarity?
There are many posts on Pre related websites that would indicate that poor sound quality is to be expected and is being broadly experienced.

Sound quality is pretty good.
