How was diagnosis achieved?
By topping off and checking how much was burned correct?
Thus, for an engine to be burning excessive amounts of oil, and then needing excessive warranty repair (I feel that a new engine is as excessive as you can get), can't one blame Nissan for the 1qt/1k miles?
If it was standard for the Z to burn 1qt/1k miles, then that's a choice you make when purchasing the car.
However, if burning 1qt/1k Miles is NOT standard, and in fact a fault in the engine/Nissan design etc, then why should the owner be held accountable for the oil?
On my 335i, we don't have an oil consumption problem... except we have the High Pressure Fuel Pump.. which is worse IMHO as having a car shut down on you is dangerous, to say the least.
In the 19k and 14 months I've had my 335i, I've had 2 oil changes;
One covered under BMW warranty/maintenance, the other I did myself at 7500.
I think it's total BS to change oil at 12-15k, especially on a twin turbo car...
Maybe stock... but for a car pushing upwards of 430wtq... I wasn't going to wait until 12-15k
But... during all this time, I never needed to top off... and my car runs at 240 oil temp Daily driving, hitting 250-260 spirited driving, and 280+ on a hot track day.
But then again, these cars have completely different engines..
I was just surprised that for a car that burns oil at a much higher temp hasn't (don't mean doesn't, I can't speak for all owners) needed a top off..
and then again, not even all Z's seem to need top-offs... it seems just a few...
So, again sorry if what I originally said came off as incorrect; it's not that one can or cannot afford the qt, it's if it's worth it.
Esther oil is about 12/qt if I've read corrected?
If so, it puts it right around how much my oil costs me.
Thanks.

Fair enough. My car was burning a lot of oil - around 2 liters per oil change. It seems to have calmed down now since my 18,000 km oil change. I was never too worried about it. If it remained an issue then I would have the engine replaced for free which to me is win/win other than a slight inconvenience of not having the car available to me.
I'm sure pretty much every vehicle made has some failure with the engine, etc. People with problems make the most noise. Unfortunately in this thread there is a LOT of people with "oil consumption issues" that haven't put enough mileage for the engine to be fully broken in. Some people are suggesting an engine isn't fully seated until 20,000 miles! For those who do have a real problem Nissan verifys and replaces. Is there really any issue here?
There are lots of comments about "oh my VehicleX never burnt a drop of oil!". So what? There are lots of other vehicles that do. Its very common for high compression engines to consume oil. If a liter or two of oil is an issue then don't buy this car. If you want what has been claimed as the best sports car value on the planet then buy a $17 gallon of Penzoil Platnium 5W30 and stick it on the shelf in the garage and do the minor maintainance of keeping your oil topped up and enjoy a fantastic sports car. It's amazing that for the very first year that the car was produced that there is virtually no problems with it.
