I have an om606.962 that came from a W210. If I'm not mistaken, MB recommends a 229.51-spec oil for this application, which is what I've stuck to in the past. This is an indirect-injected turbocharged diesel with a compression ratio of 21.5:1.
More recently the engine has since been relieved of its emissions equipment, and improved fuel supply means soot is a much greater concern than it used to be. Should I be prefering HDEO now? Something with more detergents and dispersants? I'm an EO novice so I'd appreciate any recommendations for reduced wear, especially due to soot or related concerns. 0W40 options highly preferred as the car runs year-round in the Canadian prairies.
