BTW, you buy approx 35,000 dollar car and $100 is going to break you? that is stretching the budget?

No, Nissan spec's *their* special oil, which has esters added, and some nano-carbon particles that they think makes it work better with the coatings on the eccentric shafts, and charges $11-$14/qt for it. Actually, they don't spec it, they recommend but do not require it. Just like Ford will recommend you put in Ford oil (if they still have it)...
Mobil1 is good up to 400F. Our cars are well beyond limp mode at 400F.
