If >50ppm, the Helix Ultra would be fine, if >500ppm, use the oil with the higher TBN (Rimula )
I only use <50ppm in the vehicle. This is readily available in SA.
I have done some more homework..
This is the same engine used in the E270 CDI Merc.
Shell Helix Ultra 5w40 has a MB229.3 spec
Mobil Delvac 1 SHC 5W40 only a MB228.5 spec.

The OM647 is a 5 cylinder diesel though!
I am new to this forum.
I drive a 2004 Jeep GC 2.7 with the Mercedes OM647 fitted.
The dealer used Shell Helix Ultra 5W-30AB but this oil is not available in South Africa anymore.
The vehicle has completed 100,000 kms (60,000 miles).
Will I be safe to move to Shell Helix Ultra 5W-40 or even...
