I asked Mobil what oils would clean up an engine that was neglected. I specifically mentioned how some PDS say "cleaning power".
This was their response:
"All Mobil 1 oils have keep clean properties but if you have not been using a Mobil 1 product, the Mobil 1 Extended Performance High Mileage or Mobil 1 High Mileage would by our suggested product for removing buildup if they meet your vehicle requirements.

So I would also add the HM to the list. Not for piston deposits but everything else.
