ATU is the acronym for Auto-Teile-Unger which is a German car parts store along the same lines as JC Whitney. Keep your M away from there... Plus, you would pay some really stupid price for the oil. Think about how much a gallon of euro gas goes for... ya... So, go to the AAFES Car Care Center on base and get them to either order you a case or they may have it on hand. A lot of the CCC on the installations here are carrying 10w60 due to the large amount of M3 on the road now... And fairly so as they charge from $12-14per quart which is a decent price but $$$ nonetheless... Anyway, welcome to the M family, enjoy Germany in your autobahn cruiser, stay safe, and thanks for serving the good ole US of A!
