Infiniti G35 Engine Break In



  • allbizallbiz Posts: 11
    I just picked up the G35X 2008 with 11 mile son it. When I drove it home there was smoke coming form the engine/hood. the dealer said it was nrmal as they put some knid of chemical on the engine to protect it on the oversees shipment. Is this true or a bunch of [non-permissible content removed]?

    When I picked up my 08 G35X with 12 miles on it there was no smoke. I have never heard of this and never had it happen.

    Yes and No...

    I also had 11 miles on mine... 10.5 to be exact.
    I also had no smoke, but I also had a 90 minute ride home, so it may have smoked and stopped before getting home.
    There is a small amount of protective oil film on the engine upon delivery. It burns off quite quickly. Over the past year, I've only seen one other person report smoke from the new engine. His dealer gave him the same answer.

    Now, if it's raining or if the roads are really wet, that's another story. In a heavy rain, when you come to a stop, you'll be amazed at just how much steam comes out of the hood. I actually filmed it once with my cell phone. It was making an awful hissing noise and the steam smelled like smoke more than steam... I though she was gonna blow up! :surprise:
    Turns out, that's also normal, so when it happens, don't worry about that either.

    Yea, I notice the steam coming from the hood when it is raining too. But if this is "normal", how come my previous cars never had this before??

    And what is the cause of this? Is there a way to make it go away?
  • I just bought a new 2008 G35x and have driven it less than 50 miles so far. I'm still getting used to having a 306hp engine and pushed it up to 5,000 RPM's a couple times while merging onto the freeway (it's pretty easy to do). Do I need to be concerned, given the manual says to keep it under 4,000 RPM's for the first 1200K miles?
  • I have a G35X with Prem/Nav/Tech. 2 questions:
    1. I have around 500 miles on the car now and it has been giving me ~15mpg. Sounds low, did anyone experience low mpg's initially ? I am not sure if the adaptive cruise control is causing this low mpg; I tried the adaptive cruise several times - I thought it was cool that it slows down if it senses other vehicles ahead of you, but it is also annoying at times . . .
    2. My dealer has suggested that I change the oil after 500 miles and has given me a free oil change offer. Anyone with a similar experience ?

    I have 500 miles on mine and I'm averging 20.4 but that will depend on the type of mileage driven also it will get better when broken in for now switch the guage in the center of the speedo display to show the average as you drive it will cause you to get better mileage as you watch it. I far from baby mine.

    This is only my opinion but search these forums and the internet, you will almost always see it is not recommended by the manufacturer to do an early oil change. Dealers are a different story they want revenue. Most manufacturers use a heavy "moly" oil during break-in to insure long life, dumping it early would be beneficial to no one except maybe your dealer .
