How about using -
Quantum Silver oil ,10w40 semi-synth. About £13 a gallon from GSF, a couple of quid more from VW themselves.
Because the VW engines have famous problems with valve stem seals, it contains a good amount of seal improver (sweller), so it could help those bikes that have a tendency to leak oil around the seals .
Wonder if it's worth putting in before you get any leaks ?
