RevUp Oil Consumption TSB and discussion

I know this is prob a stupid question but I am adding 1qt of oil in my 06 engine every thousand miles....my question is do I still have to do my regular oil change at the 3000 mark? Or could I go without an oil change a little longer since I have new oil circulating every 1000 miles? Thanks in advance.
Assumptions for Case 1
1) REV-UP motor
2) Top off 1 qt of oil every 1000 miles
3) No oil or filter changes
Assumptions for Case 2
1) REV-UP motor
2) Oil and filter change every 3000 miles
Notice that after 6000 miles, almost 1/3 of your oil would be 6000 miles old! Also notice that after the 2nd oil change of a brand new engine, 11% of the oil is from the 1st oil change and 1.7% of the oil is still the original oil.
This should be interesting for those that are doing UOA. I would think that because of this you would need to wait until two oil changes before being able to make strong conclusions about changing oil types. After one oil change, 11% of your old oil is left in the engine. After two oil changes, only 1.7% of the oil would be the original type.
Beyond old age, the other question is filter life. After a while, your filter will become dirty, and if you use a bypass filter, you will begin to stop filtering your oil very well.
If you were using a high quality synthetic and a good filter, I would be tempted to change the oil every 4-5 thousand miles but no more.
Bigger question is why are your driving the car that way? I would have thought that you would have gotten Nissan to give you a new engine by now.

That is a good question. Oil capacity of the engine is 5 3/4 qts.

My UOA's are not skewed when I change oils or add same in between OCI's, according to my Tribologist. Formula changes and oil performance is quite apparent when I change oil types/brands, but valid assumption and thought the same years ago. -edit- However, -edit- nice number crunching btw...
Agree. 5k mi is as far as I'd push Synth in any VQ.
Agree and should be in OC testing with Dealer imho.
No question is stupid, but why not start OC testing with your dealer especially with that OC rate and being an 06 (power train warranty still valid unless you're over on miles)

Front page of TSB (found on post #1 here) discloses which ones have this issue much more-so than others, hence no TSB on those 'others'.

Thanks for the quick response guys well I actually have a 03 Z and blew a rod in my block so I got a good deal in a 06 rev-up. I like the rev-up very much I can live with adding a qt every couple of miles. Thanks again big help

I had an oil change 2 months ago with synthetic....and as of 2 - 3 days ago my car starting making a LOUD pinging noise when I was in the 2k-3k rpm range. I take it to the dealership today and find out that I only have 1.5 qt's of oil in my car! I have only driven my car 2k or so in 2months. I have to go back in 1000miles 
I had plans to put on my turbo kit, thanks god I hadn't done it yet.

Hey I just thought I'd poke my head in here for nostalgia sake, and I can't believe this is STILL an active thread!!
https://my350z.com/forum/6666033-post3700.html
I was one of the many who went through the buy-back process.
I've been driving an '06 Acura TSX 6MT, and I have to say that I really, really miss my Z.....
But on the bright side, this has been the most trouble-free car I've ever driven.
Good luck to you guys still with issues.
Right now, priorities are B-School, First Home, etc. but I hope to get another performance car down the road!

Yes, Maxima 6 speeds have this issue as well. I believe the altima 6 speed's have it as well. If your automatic I would check it as well. haven't really heard of any issue's with to many auto drivers.

HR's I'm assuming are in the clear with this, but I don't troll HR sections to know for sure. I'm a revup DE and all I research on.
Wow Maxi and Altima 6mt's. I believe non-revups are in those, but don't quote me (depends on their hp and redline whether a revup or not).

But as far as I know, is the DE and Rev-up guys have this issue, it seems to be more common with 6 speeds though. There's at least 10 threads about burning oil on the 5.5 gen and 6th gen 6 speed maxima's on maxima.org

Update:
Failed the OC Test
New Long Block from Japan has arrived and is being installed
The dealership is also installing headers, pulleys, lightweight flywheel, new clutch and all silicone coolant hoses. WHEEE!

That's for a 'dry' engine (overhaul or fresh remanufactured). Normal capacity w/filter = 5qts.
My UOA's are not skewed when I change oils or add same in between OCI's, according to my Tribologist. Formula changes and oil performance is quite apparent when I change oil types/brands, but valid assumption and thought the same years ago. -edit- However, -edit- nice number crunching btw...

5.75 qts is the oil capacity of the engine. You are correct that when we do an oil change (with filter) that the amount of oil that we have to add is 5 qts. However, the amount of oil in the engine is still 5.75 qts. It is just that the 3/4 qts can't be drained out of the engine. So if you add 5 qts of a different oil to the engine, you are adding it to 3/4 qts of the old oil mix. So, when we do an oil change, we are only changing 87% of the oil.
Now, maybe that 13% of remaining oil doesn't matter, but it would seem to me that a UOA could be off as much as 13% off. However, if a new oil was used for two oil changes, then the amount of the old type of oil would be only 1.7%, which is pretty insignificant.
Of course, I could be wrong....

I have an 06 and my car burns alot of oil due to this if I take it to the dealer and have them run a check on it are they obligated to replace it if it fails the oil consumption test?
