My understanding is that at one time oil contacted the turbo directly while spooling and one had to wait as it spooled down before shutting off the car to insure even heat distribution. But I am not an engineer and do not pretend to be one. I know Ford has made it clear that you do not need to use synthetic oil in their turbos on the modern SHO's...
Ford, a great name in building turbos, only 15 years behind those outdated turbos I have.
I sincerely doubt that, but okay whatever...I've never thought that highly of VW's consistency of quality either. I'm pretty sure 15 years ago, VW unleased the 1.8L Turbo from the deepest plain of [censored]...
Hardly state of the art. But I really cannot connect a Ford turbo somehow being less advanced when it seems that a typically syn-blend oil seems to allow them to go hundreds of thousands of miles without failures being a norm or known issue..
I did recently meet an owner of a 15' GTi whose engine grenaded at the mall in a bar as he was waiting to be picked up. I think he said that the timing chain was a known "issue"...

Interestingly, while FORD claims you do not have to use synthetic in turbos in the U.S., in Europe they strictly recommend 5W30 or even 5W40 full synthetic, and ONLY synthetic oil.
I don't know what we're talking about as far as Europe and which cars since they have different models - although perhaps to a lessor extent than they used too. In any case, that also tells us nothing since synthetic is pretty much the standard in Europe with some limited exceptions and is probably much more readily available. They also use different suppliers (Castrol) in Europe and perhaps have higher horsepower specs, at least in the UK, for cars like the Focus ST. Again, not really very meaningful for conclusions...
Incidentally, Ford does recommend full syn Motorcraft for applications here as well.
Of course, looking back at 1996 when VW introduced 1.8T engine, it was state of the art. I see those engines today with 400K and see them failed with 50K, due to inclination of average American driver to go to 10 minute oil change.
As for Ford, you have to take into consideration that Ecoboost technology is coming from Europe, from Cologne and Ford European division. Ford had to be present with turbos in EU much earlier then in the U.S. Granted, due to strict speed limits in the U.S. cars/trucks are not as exposed to high speeds of EU HWY's where you have Ford Mondeo (which is Fusion for the U.S. market, just bit downgraded) being capable of speeds 155mph (in certain versions> Ford Focus ST is 100% European FORD division development.
So, what Ford does is same that VW did in 1998 when they brought 1.8T engine to the U.S. Play into hands of people who just do not like to think what they drive, what is under the hood etc. Make life as easy as possible. Ecoboosts are having dilution and CBU issues, and Ford updated oil choices alsready from 5W20 to 5W30 for Ecboost in order to address thee issues.
Going to OP.
If you drive that Infiniti hard, stick to ACEA A3/B3 B4 oils, because that engine is specd. for those oils.
If you just like to coast around, just up it to ILSAC-GF5 full syn. 5W30 or 0W30.
