Alfa now recommend 10W60 for a TS. They used to recommend 10W40 when they first came out (iirc) but revised it to 10W60 down the track.
However I personally use Shell Helix Ultra which is a good quality fully synthetic 5W40 oil and many on here seem to agree that there is no problem using a fully synthetic 5W40 in these cars.
So my recommendation would be to either go for the 10W60 (expensive and probably a bit unnecessary) or get a good quality fully synthetic 5W40, especially with winter coming up over there the 5W40 may be a better bet.
