Then there is the engine, check up the oil's spec's and look at its sheer capacity hopefully it's high enough to keep the cam lobes protected.

C3 is HTHS >= 3.5 and A5/B5 is 2.9 - 3.5. C2 is >= 2.9.
My conclusion looking at this a few years ago, before ACEA-16, was C3 oils provide more engine protection than A3/B4 at the expense of fuel economy.
I use the Fuchs ProFlex and find it to be very good. There seems to be noticeably fewer regens than with the other oils I've tried, and the oil consumption is very low. The Penrite C3 also seems good, and is cheaper if you buy it when discounted.
