Don't forget this is a rebuilt engine, I would (and have with mine) just go with a good quality 10w-40 semi synthetic. Full synth is a good idea with a worn engine with high consumption but starting from fresh I would use the recommended.
I do concur with the varnish like deposits that Selenia seems to leave behind, however, lets not suggest it is not a quality oil. I have run my Alfas for years on Selenia, as a rule only do oil changes at 12k, and have never had a problem.
