What Impact Can Soot Have on the Oil?

Increased soot levels can cause sludge, and clog oil filters. If soot particles are allowed to agglomerate or clump together, they may also cause abrasive wear to important engine parts such as the crosshead. Over the long term, increased soot levels can also lead to the formation of deposits on the pistons.

Higher amounts of soot can also lead to an increase in the viscosity of the oil and a loss of pump ability. This may prevent the oil from flowing freely through the engine and lubricating critical parts effectively.
