Go to the Amsoil website www.amsoil.com and there find a list of recommendations for your vehicle. I prefer the 10W-40 High Performance synthetic in my '90 300E but your engine is newer and may have less than the 143K on mine. When I bought the car it was using a quart every 800 miles or so, part of which could be attributed to a small leak in the head gasket area. Now after running the Amsoil for a year, the consumption is around a quart every 5000 miles and the leak has virtually stopped. Not typical and this is not an Amsoil ad, merely one man's experience with one oil in one car. And no, I'm not an attorney.
