I let the car sit all night and checked it this morning and it was a little more than than a quarter of the way down from the H mark. I do not know for sure how much this is. What killed me was the dealer told me that it did not burn any oil at all, lucky I checked it and service manager and I went around. Does any one know how much oil actually registers on the dip stick itself?
Yep 1000 miles it is for return check on the oil consumption, I took mine to the dealer on Tues and they did an oil change and spoke with the master tech about the problem that I noticed with oil level. He said that they had not heard of any Z's having problems with oil consumption. He did mention however that the Altimas had a recall for oil consumption, not the VQ. I am now awaiting the 1000 mile interval and I do alot of highway and local road driving. I am driving it like I normally do and I will post anything that the dealer finds!

From the Low mark to the High mark is suppose to be 1 quart. This is supposed to be the same on all/most cars. Make them check the oil level with you there and then state that it was at the high mark initially. You may have to let the car sit for >2-3 hrs as I notice if the car sits over night, the oil level reads higher then if you check it 1 hr after driving it. Keep on them, continue to do the oil consumption check. Have them check it at 1,000 miles, and 1,500, all the way to 3,000.
Also, as mentioned in previous posts...does anyone know that replacing the engine with a long block actually fix the problem. Seems like if Nissan is not sure what the problem is then what good would a new engine with the same defects, either mechanical or programming, do for anyone. Could someone with an 06 MT Rev-up engine please comment on whether or not a new engine (short or long block) did or did not solve the oil consumption problem.

A new short block did not fix my oil problem. it still sucks down 1 quart every 1,000 miles on average.
I'm waiting till Nissan figures out what's wrong with some of these 06 rev ups before I deal with the dealer again, since all they do is create more problems, oil leaks, dents, scratches etc.

Engine Builder's response to this issue
Guys, I wanted to get the opinion of a professional engine builder/modder of the Z. So, I PM'd Sharif from Forged Internals. His response, to me, was reasuring in that there was indeed a solution in sight - build the thing right with quality components. Here's what he said:

If you have, does any engine building or mods by you or anyone can fix this? Some folks thinks it's the VVT addition from the factory on this engine. Please let me know what you think. There's a thread on the oil consumption if you're curious. Thanks.
High oil consumption is defintely a factory defect of some kind. The engine has clearances issues...guaranteed. Will the dealer warranty the engine for you?
But to answer your question, a fresh rebuild will fix the problem.

I would like to retract my previous statement that higher revs would increase oil consumption. The first 1,000 miles with RP 5W30 I shifted around 3K rpm and drove the car mostly between 2-3K rpm. On the highway I would run around 65 mph in 6th gear. It burned about 1/2 quart in 1,000 miles. After reading that some people noticed less oil consumption with increased revs and harder driving, I decided to give that a try. Over the past 1,000 miles with the same oil I have shifted around 4k rpm or so and on the interstate I try to keep the rpms around 3K or higher. I have also driven 120 straight highway miles each way (240 miles total/round trip) these last two weekends (480 miles+ highway). Now I am only about 3/5 to 2/3 of a quart low according to the oil stick. I did NOT add oil after the first 1,000 miles and so really I have lost < 1/3 quart over the past 1,000 miles with increased revs. Either the car likes being 1/2 quart low or it likes the increased revs as several other people have noted. Car has 8,000 miles now. Maybe the rings are still seating?? Maybe the VVT??? Not sure. I will try another 1,000 miles with increased revs and check the oil weekly. Higher reving and harder driving would cause the ECU to try to maximize the amount clean air through the intake and decrease the duty cycle of the EGR and other envionmental friendly systems. I dont think this would change the PCV system though. Damn, I need to install a catch can to quantify the amount of oil lost throught the PCV system.

going through the oil consumption test now.
I know that it will be a tough fight...
i've had pinging issues (although less now that the weather is cold),
and was even told to replace my k&n drop-in because that may be causing the problem...LOL.
btw , I've yet to mod @ all given the pinging, and now that I see that Nissan could even try to use a drop in air filter as the cause of a problem,
I'll BE GETTING RID OF THIS CAR VERY SOON!...

FYI- for those who are talking about driving style etc effecting oil comsumption (to the point of burning as much as we're talking), I just asked a friend who drives Top Fuel dragsters and has his own 900hp Mustang.
His Mustang burns virtually no oil...... it ain't driving style.... it's a defect.

My dealer was supposed to call Nissan Tech to find out what to do next. I had to call him back before Christmas and ask him why he never contacted me. He said he had to check with the service manager as he was the one dealing with it. As of today, no further call. Tomorrow, I will call back again. GREAT SERVICE NISSAN!

In regards to your statement that maybe the Z likes being 1/2 quart low.
I wonder the same thing too. I wonder if it's possible that for whatever reason that when you fill a rev up engine to the Full mark, that it's for whatever reason Too much oil and it burns it up and spits it out the tail pipe?
One thing I have noticed is that lately I can't seem to get the oil level to read at the full mark. I let the car sit for about 2 hours and check the level and it was exactly in the middle (1/2 quart low). I then added exactlly 1/2 quart and let it sit for 2 more hours and it went to the 7/8ths mark. Then I added 1/8 of a quart and let it sit and it still read 7/8ths full.
I'm kinda at the point now where I don't really give a crap how much it burns, as long as it has enough and doesn't blow up, I guess it's all good
(will work for new engine)
Or sue Nissan

I agree that the oil stick is deceptive. It read 1/2 way between H and L so I added 1/2 quart of oil. Ran the engine for about 20-30 miles of city driving, let it sit overnight, and the next morning it read just over 3/4 full. When I first do an oil change and use exactly 5 quarts the stick reads right at the H mark. Today, the stick read 1/3 above the L mark so I added 3/4 of a quart and then drove 20 minutes to work. 8 hours later it read around 3/4 full so I added the additional 1/4 quart and drove home. The engine does seem to be smoother with the increased oil. Maybe its placebo, who knows. I will check it again tomorrow morning. Also, I plan on switching to heavier 10W40 RP and see if that helps any. I should make the local dealership aware of the problem, but 1. Its burning only 1/2 quart per 1,000 miles. 2. I do not believe Nissan has fixed the problem yet. 3. I have a popcharger and Nismo exhaust that I would prefer to take off prior to taking it in.

^Is the car parked on a perfectly flat surface everytime you check the oil?? I know what you mean, its like not all the oil you pour in registers on the dipstick, its pretty weird....and stupid. Everytime I use the dipstick I wonder what idiot designed it.
