It says the oil must meet ACEA A5/B5-08.
The only difference between the specs:
A3/B4: light duty
A5/B5: extended use and engines capable of using Low Viscosity Oils with HTHS Viscosity of 2.9 to 3.5 mPa*s.

The service interval is 15,000 km but I change every 10,000 km so that's covered, but the other part, does it really matter?
It DOES exceed the M2C913-C spec required, D is just the next iteration of the spec right and they are backwards compatible?
Checked oil levels today and about 3/4 way up the stick.
Only worried about the DPF on this one.
