There seems to be a huge variety of Mobil 1 0W-40 oils, presumably due to product replacement, the two current ones (European and US) seem to be the following:
Euro (global):

US:

For added fun, neither is an exact match to the specs of the one your car was filled with at the dealership and you linked to... that said, I'm not an expert, but it would be very surprising if this could cause any problems for you. (If anything, going by common sense and general experience the Euro spec would be tighter and better for your car.)
