Suppose you had an engine with a bit of deposits in the top end and you wanted to use an oil that would help clean it up. Or maybe you bought a used car with unknown history and you wanted to clear out any crud that may have built up from missed maintenance.
Are some motor oils better for cleaning up an engine than others? If you suggest one, please give a reasoning as to why it cleans well.
