Mercedes diesel engines from 2007 on require special low ash oil formulations to protect the DPF system. Oils must meet MB spec 229.51 and the oil that Kevin-B recommended (even though it isn't a specific diesel oil) was specifically developed for this application. Standard diesel oil should not be used if it does not meet the required MB spec.
Here is a list of
approved engine oils for the MB 3.0L diesel.
