rroope said:I believe Selenia is owned by Fiat s.p.a. . . . may be wrong?
I always use Castrol GTX Magantec on my FIAT's (former 2 Brava's and current 2 Stilo's) as it makes them sound smoother when cold and helps protect the engine too, and it exceeds FIAT's stated requirements (its the 10W/40 you want as it's Semi Synthetic and API SL, think FIAT Selenia oil is API SJ?)
