03' A4, i normally run Mobil 5w-50 full synthetic oil, but the other day i went to do an oil change, they ran out of Mobil 5w-50 synthetic and poured in 0w-40 synthetic (specially made for European cars) but it kinda makes the motor run stiff/rough, but stronger. Have anyone else used this type of oil for you A4's? Please let me know if this oil is ok. thanks.

Your 50wt oil is thicker than the 40wt oil you say makes the motor runs stiff/rough.
I'll stick with my M1 0W-40 that carries the VW/Audi spec approval.
