I'd give Blauparts a call.
Blauparts actually sells their Ravenol on eBay and Amazon. In fact, almost all the Ravenol sold on Amazon is in fact from Blauparts (but they use Amazon's fulfillment, meaning you can get free shipping if you have Prime)
Also, the Ravenol DXG 5w30 does appear on the official dexos1 gen2 approved list
The production has probably just begun and isn't available for retail sale just yet.
