Ty my knowledge vw dealer put shell helix ultra 0w-30 on my last service 504 spec. I think IF they use Castrol its 5w-30.
Thanks, that’s interesting.
My service is not due for 2400 miles/ nearly 2 months but i’ll get it done a little earlier- and I’ll be sure to ask what oil they’ve put in.
Thanks for replies, you’ve helped me make up my mind
