Grimlock, actually i think it isn't the place of manufacture that really matters, but whether a particular formula of the oil is available thr the local retailer of the brand. E.g. the German made Castrol Syntec, not easily available here is PAO-based and is supposed to be the next best thing after ester-based oil like Motul/Amsoil.
Most of the OTC oil(incl this BMW 5-30w) here belong to hydroisomerized oil (aka API Group III) and is nothing more than refined mineral oil to be exact....anyhow they're legally allowed to be claimed as "fully synthetic" otherwise.

NB PAO-based = API Group IV, Ester-based = API Group V

BTW, I don't think there is a effective "shelf-life" for the engine oil so to speak and you never know when the oil is made just by looking at the bottle. As long as the formula is up-to-date, probably not too much to worry anyway.

As for the Motul V300, I used 5-40w before but will definitely try the 5-30w on the F10 first......Probably will only change to 5-40w if the engine consume too much oil
