If the Eolys is depleted, then you'll clog up your DPF which will need long runs to clear it and in the longer term probably force an early replacement. None of this should cause fuel to get into the engine oil - that's a much more serious issue.
The service department man I spoke to seemed to think that which additive it was for that model was far from obvious but that may have been misleading.

The body is willing but the mind is weak.
