I would also think the differences in DXG formulation between meeting Dexos1 and Dexos1 gen2 would be slight. If I understand correctly, DXG's Dexos1(original first generation) approval expired 31.08.17(per Ravenol's web catalog) so would have to be renewed anyway.
The new old-stock (NOS) Ravenol DXG dexos1 Gen1 oil you got is fine for non-Turbo-GDI engines. Great stuff actually.
A lot of online retailers actually buy old left-over stock and sell it online. I really think they should divulge that, but thats an ethics issue some are not on-board with. Selling old oil is not generally any safety issue, like when TireRack has 4 year old overstock tires on sale, they divulge it right on the website, and that would be a bigger problem than old oil.
The Gen1 formula has too much calcium and sodium, which makes it a bad choice to pass the new dexos1 Gen2 LSPI tests, that's all. Not a problem for many engines out there. Of course the presence of at least some POE in the old Ravenol does help lower LSPI events, although probably not enough to overcome the Ca+Na problem.
You can bet the Ravenol DXG formula has changed, due to LSPI pressure alone.
