Nissan releases TSB NTB07-088c: 2005- 2006 350Z: Engine Oil Level Is Low
Released: 11/27/07 (discontinued)
Revised: 02/27/2008 (discontinued)
Applied Vehicles: 2006 350Z (Z33) with M/T: 2005 350Z (Z33) Track and 35th Anniversary Edition with M/T
Good news for oil consuming engines, after 2 years of fighting with the dealer and Nissan North America (NNA). NNA finally released a Technical Service Bulletin that will now take only a visit to the dealer to record an oil fill (top off) plus one more visit maybe two, for a look up on the Oil Consumption Chart to determine if the engine is to be replaced at the dealer level. In the past there was this long agonizing painful process of arguing with the dealer and NNA to accept responsibility of a mechanical defect in the engine, that 1 qt per 1k mi was unacceptable. Today the dealers have a guidelines set forth for all dealers to comply with, not to mention we now have the same chart.
Basically the TSB is if the engine is consuming at or more than 8mm below the top of the “H” crosshatch mark within 1001-1500 miles from a dealer recorded” check and refill oil level”, or an “oil and filter change”, the engine will be replaced (may need two recordings) with the V2 part # 10102-AC7MZ. No more hassles, no more ignorant dealers saying “It’s normal to consume 1 qt per every 3k mi oil intervals”.
Ok, now in layman terms:
Oil level is >1/3 qt (8mm) low, car has 2k mi on current oil change.
Have dealer confirm the reading and document on your file, dealer tops off oil and tells you to come back in 1k mi.
1001 miles later you check it and its 8 mm 1/3 qt low or >, take it to dealer to confirm reading and your engine will be replaced. It’s that simple.
Congrats to everyone waiting in the wings hoping their OC will reach what used to be the standard 1qt per 1ki miles for an engine replacement, can now line up Monday morning at their dealer with this TSB in hand and get an engine replaced.
Print it, share it, keep this post handy, and pass it on to the next enthusiast.
New TSB as of 04/28/08:

Here is a link to another method for engine break in. This method maybe controversial, I am only posting it for your own decision on which method to break in a new engine. Note: Most dealers will run the first 20 miles on the new engine before they hand it over to you. http://www.mototuneusa.com/break_in_secrets.htm
V2 Install Stats List
This list is all of our contributing members that have posted up their oil consumption on their new V2 engine. The tracking is on oil consumption, current miles on engine, oil type used. Please feel free to contribute when you receive your new replacement engine, this list will determine if the V2 is succeeding or failing with oil consumption. It will provide us with the indicators as to whether we have finally accomplished our goal or need to band together again and voice displeasure to Nissan and demand another engine revision. With the recent TSB I am hoping that the current list will triple in a month or two.
The measurements for oil consumption will be “mm
” not quarts; this will keep all on the same page as Nissan’ TSB.
The V2 Install Stats List will be updated on this page. I will notify with a post when it’s updated.
The template below should be used to post your stats.
