2011 Nissan GT-R Owners Manual:

Page 311 in 2009 manual states:
"ENGINE OIL RECOMMENDATION
Mobil 1, 0W-40 (100% synthetic) is the factory
fill oil. The VR38 engine with its plasma-sprayed
bores was developed using this oil. NISSAN
cannot ensure proper engine operation and
durability if other 0W-40 synthetic oil is used.
If Mobil 1, 0W-40 is not available, Mobil 1,
10W-40 (100% synthetic) may be used; however,
some performance loss may be noticed."
Section 9-5 of 2011 manual states the same exact thing. So Nissan probably is still approving this oil
I had just seen the owners manuals too. I remembered this thread and came here to post that same quote. Glad you already had!
I think that is a pretty huge approval for Mobil 1 0w40 in the GT-R. I've never seen a manufacturer so strict on a recommendation from my recollection.
I think it's worth mentioning that if you go to M1 website and have them "help you choose" an oil you'll end up @ M1 0w-40 for the GT-R.
