  • Considering g35 or g37. Like the lines of coupe better. Is the back seat in the coupe ok for kids 9 and 14 or is it too small and claustophobic?
  • The back seat of the coupe is very tight. Our granddaughters (all under 5 yrs) are cramped back there. As your kids will only grow larger, I highly recommend the sedan.

    I get one as a loaner during service, and it carries everyone with room to spare.

    does anyone have any experience with snow tires on a 2008 G37S ? What is the smallest (diameter) rims/wheels that could fit on that model?

    I had the same problem at start-up when cold (lower than 50 degrees or so outside temp). The noise is almost like when you have just change the oil in your car, everything drained, and the car is filled with new oil. It had that clicking noise, valve-tap almost. I called the dealer and they also mention an oil change with Ester oil, for free (only the first time I supposed?!).
  • The noise was definately from the valvetrain, and was at random. Ester oil corrected the problem immediately with no further occurance (1500+ miles). Yes, the first Ester oil change was free, but I own the rest of them.
  • I’ve read the “Ester” oil remark here before. Is there a brand name? Is there a service bulletin?
  • 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.

    Happy motoring.
  • hi,
    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.
    thanks

    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.)
  • snagielsnagiel Posts: 750
    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.
  • carnaughtcarnaught Posts: 1,569
    Well, I got the Palm Pre and not only does it work, but I can answer calls and the caller i.d. comes through :surprise: . 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.
  • carnaughtcarnaught Posts: 1,569
    Sound quality is pretty good.

    Does anyone know when the 2010 models will be launched and when they will actually be available?

    Also, based on historical evidence do you think the new models will cost more or will they about the same? And will the 2009 models be cheaper once the 2010 models have been launched?

    Thanks

    I think the main reason they tune these VQs that way is to reduce stress on the drivetrain. Going from 270 to 300 tq would probably require an upgrade to the drivetrain while high RPM horsepower doesn't. Still, we're not suffering here like a Honda VTEC motor used to be! In a couple years I think the direct injection may help a little bit with a bit more power but not sure. Although, I bet the automatic isn't the problem, it's probably having more torque would over stress the clutch and shafts so they tune it for higher RPM, just my 2 cents. :shades:

    The more I'm using the Palm Pre in the Infiniti, the more I am intending to agree with you. In fact, I may have to take advantage of the Sprint 30 day trial period and relinquish it.
  • rdesmanrdesman Posts: 43
    I know I've considered giving my Pre back as well but decided not to as I really like the phone. If it didn't work at all well then maybe but I can tolerate the imperfect sound in the Infiniti rather than give the phone up totally. It would be even better to lead a REAL life and not worry about crap like this.
    If you do decide to return it let me know and I will not torment you by advising you when the next software mod comes down the line and fixes the problem.
