I'm currently in the same boat as you with my 2010, I bought the car march 2015 and I've always used Mobile 1 5W-30 full synthetic oil (Bad idea). I did Autocross, HPDE, 1/4 mile and the ocassional runs to mexico, I always kept an eye on the oil because it would burn a little after really spirited driving and I had no oil cooler so it was to be expected.
Last march when i was changing the oil a week after a track day it was around 3qts low which i thought was a bit excessive so i started keeping an eye on it, come June it was 2qts low not as bad as before, then in September it was 2qts low after 1500 miles due to 1 night at the 1/4mile and some mexico runs all in the same weekend, so i topped it off. In December I did another oil change and installed an oil cooler which helped. Come oil change time in march the weekend after TX2K17 it was 2.5qts low due to 3 consecutive nights of mexico runs.
A friend suggested i try a different oil weight so a month ago, I did an oil change and I went with Castrol edge 0W-40 (European Formula) its been 1K miles and no sign of burning, i'll be doing a track day in 2 weeks then ill really know if it made a difference.
I found the TSB and my car falls in the VIN range my car. I bought my car about 2 years ago from a Lexus dealership also bought an extended warranty but its not a Nissan warranty, currently it has 77K miles so I don't even know if it will cover an engine with this much miles.

Dang man sounds like your oil consumption is terrible. Hopefully your extended warranty covers you because it honestly sounds like you're either in dire need to replace the engine or you might as well just trade it in for a 2011 and up Z since the 2009-2010 have the recall. But it sounds like you got potential now to not deal w the oil burning issues now that you changed the weight of your oil? If you haven't burned anything after 1k miles you may just be lucky enough to be in the clear.... but dude you shall keep me updated in this thread and hopefully we can get our Z's to no longer burn oil anymore. And if all we need to do to fix the problem is change the weight of the oil then that's an easy fix for us!

Idk man that's a good question, as far as I know all of the 370z's have the same set up so idk why exclusively 2009-2010 would have this issue..
