If the information presented by Mobil is correct "your vehicle manufacturer recommends a 0W-30, 0W-40, 5W-30, 5W-40 or 5W-50 viscosity and oil that meets MB-Approval 228.51, MB-Approval 229.31, MB-Approval 229.51 or MB-Approval 229.52.", then an API HDEO like TDT is similar to specified oils (MB 228.51 - in terms of sulfated ash, important for DPF longevity) except ZDDP is slightly higher (than 229.31/229.51).
Unless it's under some kind of extended warranty, use away. Also consider Rotella or Delo 5w40. A good spec oil would be Valvoline Synpower 5w40.
