Well, another thread here asked about Mobil Super 3000 0w-20 synthetic here in Canada. This is probably one application that will see it, since Imperial Oil is the service fill and not everyone will splurge for M1 at the dealer, and the Nissan Ester Oil probably has dust on all the bottles, since the only ones that would buy it have more money than brains.
If the dealer is going to put in 0w-20 (either Mobil Super 3000 or M1) for the same price as Mobil Super 1000 5w-30 conventional, fine (although the Infiniti dealership here charges through the nose for any oil change). Here, it's close to $70 for a conventional oil change at the Infiniti dealer. I can do it for under $15 with PYB on rollback and a Bosch 3300, or a couple bucks more for the Wix.
The 3 month/3750 mile severe service interval is way, way too short to be using extremely expensive oils, or, for that matter, cheap oils at very high dealer oil change rates. If it were me, I'd run the 5w-30 conventional at severe service intervals until the warranty expires, than play around with something like a 0w-20 or other synthetic if so desired.
