TSB: 2009-2010 Nissan 370Z: Engine Oil Level Is Low

spearfish25 · 10-29-2010, 10:28 PM

^Nice. It's incredible just how generous Nissan is with 'acceptable' oil consumption. I've never seen my dipstick reading drop anywhere close to 18mm over 3k miles on any car!

well as of nissan wont tell us nor do they give reasons for the oil consumtion, but. i have asked some older 30 year master techs at nissan training about it, and it supposivly has always been a problem with nissan engines with the rings not seating correctly... with either the manufacturer of the rings or the cylinder wall surface. no body really knows except for the higher ups at nissan who wont disclose any info

Cough, cough.... forgive me, but that is pure "bovine scatology". Piston rings, especially very hard ones that are in this engine, take quite a long time to seat. Break-in period is quite long. For heavens sake people.... RELAX!! How long must this insanity continue before people will just give these engines 10K miles to properly break-in?

My engine..... 9500 miles..... oil consumption..... NIL!! Yes, it did use quite a bit of oil during the first 5 or 6 thousand miles. But now..... NOTHING. A B S O L U T E L Y N O R M A L !

(WOW)

Your engine is still young dude. Mine didn't start drinking too much oil until about 15k miles. I am at 17,700 and going through 2 quarts every 3k miles. Just because your engine is acting normal now doesn't mean there is no problem with any other 370Z engine on the face of the earth.

6mt is right.....in most cases!

I will however side Import111 in cases like his and mine. My first engine did not use oil until around 6k.

Maybe this has something to do with it.

I heard that low friction DLC just makes the oil 'slip' past the valve seals and burn off more easily

This is not a problem of DLC, this is normal for all (0W60), 5W30 winter & summer oils that are put inside the engine because of a world wide climate selling strategic desicion because of a cheap purchase deal for this oil. This oil has a higher consumption if the engine is not hot (often short track driving MacDonald disease.. i have the 2 fast and 2 furious pick up tool ever..joking ) . Its only normal temperature tolerance with high viscosity oil.. physics ..thats all. That means not that this viscosity is a bad choise, it only has a higher consumtion than a 10W40 (allowed in the 370z german service manual) in the cold start phase..thats all. Of course its the best choice for the manufacturer.. But if you read the nissan bulletin..there must be a production issue too.. and that is not acceptable...
P.S. this funky oils kill the mass flow senor faster if you have a turbo engine and a high rpm longtime abuse driver in cold start phase and some age on the turbo bearing..selfdestruction procedure with the knowledge gap blubbering forum users...the preference dividend of the tuners (colored pullys)

Thanks AK! I'm definitely going to the dealer with this in the near future.

There are only two possibilities for hight oil consumption

may quality issues including normal human overload because of cost reduction on the powertrain production (price orientated hight power product not hand crafted) or coustomer rpm abuse at cold oil
a) piston and ring surface (honing in production)
b) intake valve

are the heads replaceable in the engine bay or does the engine has to be removed because of the abnormal "low" noise that was mentioned , this sounds more like a head problem. Abnormal piston noise is louder :-)

I have no oil consumtion @ 10k km with the first oil, what is normal for proper brake in and of course no abuse and all todays engines behave like this if there was no quality issue in production.. oil type of course didnt matter because of API (for the oil popes who belive in healing through blessed fluids..best indulgence discussions)
