WHAT IS ENGINE SLUDGE AND HOW IS IT FORMED?? Engine sludge is a thick, jelly-like substance that is detrimental to the performance and extended life of an engine. Sludge obstructs oil passages and restrict oil flow. Once built up it reduces heat transfer, increase the operating temperature and hampers engine operation. Sludge will ultimately lead to shorten engine life.
