I use Castrol Syntec and it works great. No need to change, and I'm glad to see these results. Makes me like it even more!

Screw the tests this is real life experience....Plus, when my rear main seal failed they pulled my oil pan it was as new inside with no residue/gunk at 117K miles. This is only possible with quality synthetic oil....

i'm not saying m1 isn't a good oil, it's fine, and i ran it forever in my se-r

but from the tests, it's clear syntec just performs better, under the exact same driving conditions and the same exact engine, the wear levels were lower and there were higher levels of anti-wear additives.

considering m1 and syntec cost the same, i think syntec is the way to go

Different weight oils work better in areas like yours where the winter temp dips well below freezing. When you consider summer driving you would be better off just using what Nissan recommends 5W/30 all year.

UOA is the only valid means of comparison, IMO. Thanks for posting this.
