late addition :)

here dataStack you can see difference between different oil standards
as i see it, c2 and c3 oils cover everything a3/b4 oils do, and in addition provide better fuel economy and are compatible with DPFs
if your engine does not require them, c2 or c3 oils are overkill, but i doubt they will cause any damage
