Used oil analyses do not give Mobil 1 very high marks with the VQ engine, but you'll get a ton of people who use it and say that it's fantastic. Crazily enough, Royal Purple doesn't do that great either.
Mobil 1 5w-30 isn't even a true synthetic and is not labeled as such in Japan, as it uses a conventional oil as a base. Their filter isn't bad at all, however. It's a paper-based filter, but it filters very well. For a true synthetic from Mobil 1, you'd have to get their 0w-40.
Amsoil's oil filter is synthetic, not paper, but it's pretty expensive. Purolator's Pure1 is a good compromise between the two, in my opinion.
Anyway, here's a big thread dedicated to your question. You'll get a bunch of people talking about how they use whatever oil it is that they've used and they don't have any problems. That kind of answer doesn't go very far toward answering "what's the best oil for the VQ37", as an oil analysis is the best way to objectively tell what lubricant works well with the engine.
What is the best synthetic oil?
