Japanjay - that is crazy that your car still has the oil consumption issue even after a full long block replacement! Good luck to you! Hope they figure out the problem. On my 2009, the scary part about it all is that their master tech rebuilt the engine with a new short block but then the engine wasn't running properly due to something that went wrong with the timing. (I may be mistaken here but it has something to do with timing I think). Basically the engine ran into a self inflicted problem and now both timing sprockets may need replacing despite the fact that one of them is only 1 month old! Definitely does not give me confidence should this problem pop up on a future Z.

Well in this case if its low you could add oil instead of driving around and totally destroy your motor from oil starvation.......but I see what you are saying. The VQ since the inception of the 3.5 has had hit and miss oil consumption problems......Z's, Maxi's, the 3.0 VQ's were a gem. etc.:icon14:

I have an 09... and haven't had any issues with it except the hatch springs.

.

It was a full long block one month prior to the TSB. So I think it was a long block from the old batch. I requested that since the block should have a different VIN stamped on that they pull the birth date of it if possible. Was curious as to how long the motor sat idle before being a new heart in my car. The master tech stated that is more than likely why it is again having this problem since it was pre TSB.

same here. 3.5k miles on this oil change and i'm still by the top.

This was meant to be a heads up to any unsuspecting person who buys a 2009, nothing more. Checking your oil doesn't necessarily protect you from the problem but it may prevent many future headaches. As you wrote...it could be MONTHS without your Z if it requires a long block replacement.

I own the 2012 and have not really seen an issue so far. This is my daily driver, so I change my oil almost monthly....

I would also like to know if steps have been taken to address the issue. With a new 2013 arriving possibly this week, I'm still a bit nervous about dealing with this issue again in the future. I know the 2009/2010 have the TSB... but I'm almost positive that I have read threads on this forum from owners of a 2011 that still had the problem. I wonder if it has anything to do with oil temperature. Do you think the 2012/2013 oil cooler helps at all? I only started to have this problem during the summer of 2012, which coincidentally was one of the hottest in recent memory in the northeast. I'm talking 100 degrees plus... causing oil temps to approach 250 degrees or higher during spirited driving.

I have an '09 with about 27,000 miles on it. Have been running Redline 05W-30 oil since the 5,000 mile mark. I use 1.5 qts every 5,000 miles and it hasn't gotten better. I just live with it, although I do keep it at the top mark all the time. I add a little oil about every 800-1000 miles.

I have recently purchased a 09 tour/sport/mt...25,000 miles. Thanks for the heads up...kind of upsetting...I wonder...someone said to check oil cold, what's up with that?

My vin is jn1az44e49m404483

Am I in trouble....? This sucks

In my first ever HPDE (I bought the car at 10K as a track car, and it hit the track at 10.4K) it used 1/4 of a quart per 30 minute session.

I have a 2009.

i have a late production 2011, according to a few techs that i spoke to when i went in for my first oil change nissan revised the engine a little during the late 2011 runs to correct issues with oil consumption and looking at their TSB for oil consumption issues it does not apply to 2011 and up Z's. 25,000 miles in on my late production run 2011 and no oil consumption issues at all.

Well that at least gives me some hope! Thanks for the info! I just got my 2013 tonight! Posted some pics in another thread.

awesome man, have to say the new look is better in person than it is in pictures...can't really say i like the new blue though, just one more dark color to add to the Z's already dark color choices aside from white, red and silver now...oh well just another reason to be glad i got a monterey blue lol

I'm about a quart low every oil change... could that morph into a more serious problem?

wat's your milage on the odo?

My bassturd uses some oil. I just check it at every fillup now and maybe have to add a quart every 3k-4k miles. Am I fine to keep doing this?

Almost 60k

It doesn't seem to be getting worse

that dont sound good.

my 2009 ate close to a quart early on, but lately no more than maybe 1/2 to 1/3 a quart. im at 16k miles.

my G was the same way, completely stopped eating oil around 18k-20k miles.
she's at 35k miles now.

meh, an engine eating a quart of oil in between oil changes 3k-6k miles is pretty standard. Nothing to worry about here.

im not too sure about that... but if you're okay with it, then :tup:

I'll keep a closer eye on it. I only have to go on what the oil change place says

Early 2011 370Z w/38K miles. No oil consumption. Oil changed at dealer every 3750 miles.
Mid 2009 G37 sedan w/63K miles. No oil consumption. Oil changed at dealer every 3750 miles.
Both vehicles purchased new and broken in according to owners manual suggestions.

Countless cars I've owned in my life have never consumed that much oil. All have used little to no measurable oil and my current Z is the same, no oil consumption. :driving:

are the 2010 build in May, conv-roadstars having the same issues of oil consumption?

2012 Nismo. 3700 miles since last oil change (switched to M1 0W-30) and hasn't burned a drop. 14K+ miles on the engine, so I'm not surprised at all.

2011, just over 34K on odo.
Every oil change has been the same, zero oil consumption.

I had zero oil consumption up until 40k miles. Every oil change for me since then, 6k intervals, has been 1/2 to a quart low. All my previous cars did the same thing as they got higher in mileage. Maybe its me, but if you google the issue or take the car to a mechanic they will tell you it is normal behavior. Maybe I need to get my car retuned.

2009 here with 24K on it, zero oil usage between 3000 to 3750 mile oil changes using PYB Baby!

For reference, Porsche will tell you that 1qt/1000 miles is allowable.

So if your Z used "some" oil (or no oil at all), consider yourself lucky.

2011 with 30k, On my 3rd short block due to oil consumption. first 2 used a quart or better in 1000 miles.. 4k on this block, and seems to be ok. Yes, I followed manufacturers break in BS on all 3

That's the general rule of thumb for most manufacturers. My 2010 roadster started out consuming oil (got it with 2.4K on its ticker, probably with factory fill still and it was > 1qt low when I first checked it). Based on my driving conditions, I run 6m OCIs and by 20K consumption had fallen to 1 qt between changes of about 5K miles.

I have run up to 7500 mi on a OC (always using 5/30 Pennzoil Ultra to date). 38K now, added .5 qt after about 4K miles

This is completely normal for any car IMHO.

- b

Yup! I fully agree about general rule of thumb. I think the "irritation" here is that some engines do not consume and some do consume. If consumption was uniform, then mass confusion would not exist.

Let's put it this way: my synthetic costs me $12.xx/qt. if my interval is 7,000 miles, this would cost me an additional $84.00, mininum, between OC. I would rather be the guy who has no oil consumption.

acceptable does not mean normal

That's what my first ex-wife used to always say.

Yes, because sludge is building up inside your engine. My wife's 2011 370Z died at the side of the road after 21,000 kilometres (NOT miles, kilometres). Nissan refused to repair it because I had the audacity to have the service done at my buddy's shop. It's a leased car. They want over $12,000 for a new motor. I had it disassembled. Here's what the pistons look like.

Oil Consumption on a New Z
 

I've been using the NEO since the car was delivered and did early oil changes at 700 and 2300 miles with the Fram Ultra synthetic filter. I observed no signs of metal particles in the oil either time when it was changed. I have done a careful and gentle break in over the 1st 2K miles, with RPMs below 4K and no hard acceleration. The engine is smooth and quiet and seems to be running quite well.

I have just put 1100 miles on the engine since my last oil change at 2300 miles and the oil consumed was exactly 1/2 cup(4 oz). This works out to about 1 quart every 8800 miles, so I am very impressed. I've had some old clunkers that consumed almost as much oil as gas and so I'm very happy with this engine. Is this normal or typical for this engine or did I just maybe get lucky with an engine that was made with tight tolerances?

I have never heard of NEO oil until very recently. It is a very small company in Socal. I think they also offer transmission and differential fluids.

How is NEO compared to Mobil-1 and the like?

I think he means Nissan Ester Oil?
