I'm new to the M40i world....to be honest...didn't know till now it was a 0W20 fill.
Looking at the specs...its bog standard ACEA A1/B1...not ACEA A3/B3-B4..usually used in performance engines...(High Temp-High Shear oil)
I think I will be going with something that remains A3/B3 etc...once out of the free maint years...
It is going to take quite a mind-shift to suddenly believe A1/B1 is good enough...
