I've read that some folks use Red Line oils for cleaning their engines, that the esters in the oil help dissolve sludge and gunk. Is there truth to this, that Red Line can help clean an engine? My engine seems to be in pretty decent shape (Camry 2.5, 81K on the engine), and I was wondering if adding a quart or two of Red Line at my next change would have a beneficial effect? Any deleterious effects?
