Primus, it tells me that for some reason, VoA did not make sure that the correct oil spec is easily obtained, and it also tells me that the same oil manufacturers, which do make the correct spec oil abroad, are currently not interested in either making or importing the proper oil for the US market. Curious indeed.
My explanation: VoA (VW of America) is, just like AoA (Audi of America), interested only in selling cars. An infrastructure that doesn't let the customer hang in mid-air is not a priority for the bean counters.! I've learned that the hard way (weeks of waiting for spare parts and special tools, because they weren't in stock in the US).
