Hi Rob,
I am from Germany. You can see that from my user on the right. It would be nice if you also indicate this in your profile. In my opinion, it also makes sense to state your Morgan model and the model year in your signature. This often helps with questions.
Back to the oil question:
BMW has approved the following oils for the B48 engine:
0W-20, 0W-30, 5W-20 and 5W-30
My BMW dealer recommends 5W30. In my experience, however, this is more a question of faith when it comes to oils. Which of the approved oils is the best and from which manufacturer?
I also ride a motorcycle, Harley Davidson. You can't imagine how many pages are written in Harley forums about oil and which is the right one.
