I wouldn't use it.

Pentosin makes more than one 5w-30. If it is the High Performance blend, it is rated API SL and while that is still a current spec, it is an old one. You can do better with an API SM or SN. If it is the Super Performance III blend, it is not recommended. It is an LL-04 oil which shouldn't be used in North America due to our fuels, and it doesn't appear to have an API certification.

Nothing wrong with Mobil 1 if you don't like Castrol or the BMW oil, IMO.
