Mobil1 0w40 concerns

I'll second that Mobil1 oil runs lean under high heat (i.e. Subaru's boxer motors & our VQ motors), the 0W-40 is perfectly acceptable to a normal 5W-30
I've been running the Mobil1 0W-40 Euro blend on my G37x for 14,000 miles now, and my friend has been doing the same for over 40,000 with zero issues or excessive wear. This SPECIFIC blend is Nissan GT-R approved, and meets all API approvals (Nissan says API 1 & 2 cert approvals)
This oil also got excellent reports via BobTheOilGuy

Mobil 1? 0W-40
If there's some aversion beyond "Nissan says 5W-30" I'm curious what it is? I looked into this pretty thorough before making the switch and didn't find any horror stories.

All that aside, I haven't looked into "experimenting" with alternative viscosity oils not covered/specified by the warranty until this thread. There is a good amount of support for the Mobil Euro 0W40 and plenty of approvals. Due to the OP's flip flop opinion on the oil, I have taken it with a grain of salt and decided to try it myself.
There is definitely a noticeable reduction in engine noise and it even seems the exhaust noise has become quieter. Throttle blips aren't as pronounced. The car seems to have a little bit of a "smoother" feel and the engine seems more refined. We'll have to see how this affects MPG's due to being slightly thicker. I don't really care, but I am just curious.
The previous oil I had in the car was Mobil 1 Advanced Fuel Mileage Synthetic 0W30 (bottle specifically calls it out as maintaining warranty coverage for 5W30).
It's only been a few days with the oil but so far, so good. Nothing similar to what was originally reported by the OP.

Is there little to no concern about all the extra viscosity modifiers needed on a 0w40 oil?
Maybe that's why mobil1 starts with a better base oil...because they have to pump it full of non-oil modifiers to get it to behave like a 0w40.

0W40 Mobil 1 European Car Formula Recommended by Seb @ Specialty Z
My engine is built by GTM so I'm a bit different than an OEM G37.
When I had Specialty Z tuning the car he recommended 0W40 Mobil 1 European Car Formula for my engine.
The car has 23K total miles (13k since the build). I hear a bit of engine noise (slight chatter/lifter noise), but never loud or concerning. I haven't tried any other types as I trust my tuner and haven't run into issues.

AMSOIL vs Royal Purple
There's a lot of emotion that people put in their choice of oil. RP isn't a bad oil. Best thing to do is research it and go to bobistheoilguy.com and research used oil analyses for the VQ37. Go with where the facts lead you and select what you like, as long as you run something compatible with manufacturer's spec.
