Hi, Mobil 1 is an approved motor oil for your car. 0W-30, 0W-40, 5W-30, 5W-40 are the approved viscosity.
Make sure that the bottle states that it meets the Mercedes 229.5 oil standard.
On your coolant you should only use Mercedes Benz Genuine Coolant.

I prefer to use the genuine Mercedes coolant.
