I know of no average cost on sludge removal....it would vary in every individual case and would depend on where and how it would be removed. Sludge in a engine is like cancer in people ....it may never be compleatly removed unless the engine is taken apart compleatly and cleaned. Best thing to do is prevent sludge with routine maintenance.
