Here in Greece, all the TSPARK engines I heard about drink a lot of oil. Might be the temperature, might be how we drive like idiots, but seems to be the norm.
On my 1.6 120CV 147 with 162000kms nowadays I have tried 3 types of oil:
ENEOS 10W40 (Semi Synthetic) No consumption until 2-3000kms, afterwards more than 500ml/1000km
Generic noname cheapest 10W40, around 200ml/1000km until 4000km, then almost a liter per 1000km
Selenia 20K Alfa Romeo, Around 400ml/1000km from the first km, actually seems to drink less the more kilometers I do.
My mechanic says that's the norm, and the 3 recommended oils for my car are the Selenia 20K, the Syntium 1000 and the AGIP ENI SINT 10/40. From his experience Agip has the lower consumption, but his opinion is to stick with Selenia if I don't mind the cost, especially since I do a lot of city driving and high speed trips.
