While browsing Walmart today I noticed Castrol has a new (to me, at least) line of Edge oil, label Edge Euro Car. Only saw it in 5w40, but they still also carried the Edge European Formula in 0w40. Both meet the VW and MB spec that I need, im just wondering if the Euro Car (brown bottle) line is any different then the European Formula (black bottle) that I'm used to. Pics below for reference
