Mobil 1 0W40 and Castrol 0W30 are the ones I'd recommend. Both Group IV synthetics, both meet or exceed MB 229.3/229.5.
Mobil 1 0W40 is the highest spec Mobil 1 oil for gas engines (MB 229.5). You don't want to use the MB 229.51 spec oil, it's for diesels and Euro IV engines. Different additives and SAPS levels designed for cars with sensitive catalytic systems and post-exhaust treatment (Bluetec). Apparently, 229.51 can have issues with the ethanol found is gas (obviously not an issue for diesel).
Castrol Syntec 0W30 (referred to as German Castrol) is an excellent oil, group IV synthetic, made in Germany. Not sure how available it is in the US?
Anyway, those are the two I've used extensively year-round. All IMHO.
