Certainly, since my '99 E320 tells me both, in the display, to add oil if I need to, and, to change it at 10k miles, a newer E350 should do the same. I have always gone by the FSS (Flexible Service System) that displays when oil change is needed, about every 10k miles. Have always used Mobil 1, 0-40 MB approved oil. Just about to pass 200k miles on the car. Must be doing it right!
