Was you replaced motor at 6.5K a V2?

Success at 4000 miles, so far so good - still pending ... I need one, if not 2 more oil changes with minimal consumption to feel it's a success

quarts per 1K = just over 1/8 quart ... minimal
engine installed end of Sept. '07 if memory serves me correct
mileage on engine = 4200
oil changed today
penzoil 10w30

I think the most encouraging thing is that there has been no geometric increase in oil loss from 1k to 2k and so on. That was the biggest issue with the v1. The first 1k would be minimal, but then would drastically increase as each 1k went along, eventually being down about 2.5qt by the 3k mark.

As a side note, this has all been on plain old regular oil.

WOW, took over a day on and off to read all 95+ pages I guess I should consider myself lucky not only because my Z is 2003 but also because I don't have to deal with all the crap dealers put the customers thru.

Here is my take on this whole Oil Burning issue:

A new car should burn very minimal amounts of oil (unless it's a rotary). I have a 2005 Mazda 3 (Aluminum engine like Z) with 30.000km and it burned 0.1 Quarts of Mobile1 5W20 in 4500 miles with oil change every 7000miles. IF a car burns more than 1 quart of oil between oil changes it has some engine issues more than that and it's a major failure.

I can't believe that when dealer finds 1q of oil left during oil change they just refill oil and tell owners to keep an eye and come back later. If engine looses more than 50% of oil and is used on continues basis first things that will start to wear out are:

Top End - Valve Train - Valve Seals - Cam journals
Oil Pump
Bottom End - Piston Rings
And finally main/rod bearings

1q of oil left means your engine is garbage, no testing required, toss it away, it's done. Also when burning that much oil O2 sensors get plugged as well as CATs.

I am very impressed on how many owners are actually taking their time and going thru all the hurdles of investigating/worrying and getting a "new" motor without a guarantee that's it's a final fix. A new car should be enjoyed, I would just return the car and get the money back and move on.

This really puts Nissan in a bad spot light, basically when you're buying a Z chances are you will be left with a car that has chipping paint, burns lots of oil, has broken tranny, broken clutch and power windows If you keen on having a Z even after all the troubles I say get $$$ back and buy 2007 model.

PS: I've checked local Auto listings after reading this thread and found 68% of Z for sale were 2006, I wonder why!

Naw pretty sure it was a v1 because they replaced it late 06 and from my under standing the v2 was not out yet, my service manager did tell me that the replacement engine did have new rings from a differant supplier and it was suppose to be the fix, but low and behold it burns oil still ,so I'm on the list to recieve a new motor and am at least hopeing for the v2 because they gave me a long story about how there is even a new motor in the works and I don't know what to believe, but when the new motor gets here I will be looking for the part number ofcourse and will compare it to what we know to be true and present in this thread

I get about 1/2 a stick on the dipstick per 3500 miles. I think thats about the same. My engine is at 15000 miles and never been replaced. So I would say yours sounds normal so far.

antennahead

Well, my V2 as you can see is doing good so far, so if you get one it should fix the consumption problem.

How many miles on the current oil change interval?
1/3 below the “H” mark on dipstick, figuring between the H and L mark there is 1-1.5 qrts, therefore if it’s at the L mark it would be 1-1.5 qrts low. Yours translates to just a hair under ¼ qrt low. If this is on a 3k mi plus oil change interval, then you are looking good. No concern, just keep monitoring it every 500-1k mi, per oil change.

ZeeForce

Sorry to hear about the continuing OC issue; please provide a little info and I will add you to the stats list.

New to the stat list, please provide the part # of your engine to verify if your engine is a V2 or V1. Unless you know for a fact it’s a V2 or V1.

Thanks, glad to be back home in NorCal. I was sick with the cold/flu the moment I arrived in Albuquerque, NM on last Monday, spent the entire week down there sick. Four walls in a hotel room is about all I saw of NM, that is once I was out of the workshop that my job sent me to attend. I am getting better, thanks.

ZeeForce

Thank you for using the format, this really makes updating the stats spreedsheet easy.

I will change the OC per 1k from 0.17 to 0.14, figuring an 1/8 of a qrt = 0.125

ZeeForce

That is very encouraging, both on OC and oil type used.

I also experienced the aging of the oil, to consumption on the V1. No OC the first 1k mi, then within the next 1k (note: long highway trips) 1 qrt consumption at the 2k mark. The long highway trips were determined to increase OC versus the city stop n go. I have taken a few short distance runs say 100-200 mile runs. The real test for me will be on a 500+ run.

Thanks, hope it remains at this level.

Wish I was at this stage in this thread.

Still with original 06 rev-up VQ. Build date 11/05.
Within first oil service at 3,750 1qt/2400mi.
Within second oil service at 7,500 1qt/1200mi.
Within third service at 11,250 improving back to 1qt/2400mi.
Within fourth service at 15,000 up to about 1qt/3000mi.
^ All on Dealer Dino 5w-30.

Now switched to Synth: Syntec 5w-30.
Within fifth service at 20,000 1qt/2400mi.
Currently in sixth service for 25,000mi (Amsoil 0w-30) 1qt/2700mi.

I have so far...filed complaint with NHTSA-office of defects, Infiniti consumer affairs with complaint # in hand being I've been verbally denied by Dealer.
Will be performing consumption test (knowing I'll be officially denied replacement afterward), then I'll go BBB.

Never met the 1qt/1000mi or worse threshold for warranty replacement.
Any one have success with warranty replacement above NNA's warranty replacement standard?

I've read this thread from here back to post #1581 and still plugging away.
Any help on my VQ situation would be greatly appreciated

I was told by my advisor that nissan originally stated that its was normal for our engines to burn some oil but then reversed it recently saying that our engines should NOT burn any oil at all.

i always thought manuals burned oil compared to auto but i guess not.. subies have problem with burning oil too not as bad as Z but guess thats normal for them


i went to WCN for the second time yesterday and burned 1qt in 500miles. have to go again on 700miles and then they are going to file my problem. they told me that no one is getting new engine right now cuz some are still having the same problem.

Thanks for your reply...I would hope they back pedal on that original statement and now say none should burn,
being I personally know ppl with original factory rev-up VQ's (05's and 06's) that do not use any oil and never have since day one new.

If all rev-up VQ's had some OC issues, then I could accept that fact and live with it, but not all do.
So I feel I'm entitled to a rev-up VQ that doesn't burn oil period, regardless of their absurd 1qt/1000mi or worse standard which addresses an obvious serious problem.
Heard this too over on Driver. Been patient for almost 2 years following NNA's development for a 100% fix.
Thought the version 2's were the answer, but think I've read here a small percentage still have OC with those and third rev-up VQ fix attempt is still in the works and not released yet. Once approved, you're put on a waiting list. Heard about waiting list too on Driver, but also heard about ppl getting the most recent shipment from Japan and those being used

Nissan North America offered me $2500 for all the trouble I've had with my Z.

Hmm....It's best for a buyback, but they should raise the $$ a little more
