Just googled this up - actually you would be amazed how Rowe is popular in Germany and good, since it works with all the major German car manufacturers as an OEM oil. Also, few people know about ISO/TS 16949 that Rowe has, and that certificate sums up the most harsh requirements set up by car manufacturers that rarely factories/blenders have.
So if you have a chance to go with Rowe - I would most definitely recommend it.
