Thanks for the link, Otto. Yes the whole point is to turn the oil into a semi-solvent and then splash it around violently inside the crankcase. That only happens if the level of the liquid in the oil pan is close to the centerline of the crankshaft. It does a lot better job of scrubbing things than you'd ever be able to do by dropping the oil pan and scrubbing with a brush and solvent. Overfill the crankcase by about 3 quarts by adding Diesel fuel to a full fill of fresh oil.
