Nissan releases TSB NTB07-088: 2005- 2006 350Z: Engine Oil Level Is Low

Released: 11/27/07

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 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 their 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 more than 2mm below the top of the “H” crosshatch mark within 0-500 miles from an 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 >1/8 qt (3mm) 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.
500 mi later you check it and its >1/8 qt low, 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.

Good News for All !

Yup...good news for 350Z peeps. Wonder why NNA didn't release same TSB for us G ppl at the same time?
By the time we get one, there will be quite a back-log for the Version 2 rev-up replacement from Japan.
But I can wait...been waiting almost 2 years to finally qualify with moderate OC issues.
