How do engine sludge and deposit form?
 

Engine sludge is a very common problem. However, if you ignore it, it can cost you dearly. That’s why your car’s engine requires proper maintenance. Keeping the engine free from sludge improves engine life and performance, and fuel efficiency in the long run.

Engine oil circulates throughout the engine and lubricates all the moving components. In other words, engine oil should be in motion inside the engine. When you don’t drive the car for a very long time, drive in stop-and-go traffic or drive very short distances for a very long time, the engine oil starts leaving deposits on the internal components.

Apart from sludge, carbon deposits also build up over time. They are nothing but the by-product of improper fuel combustion. Similar to sludge, it gets collected on the internal of the engine. It can lead to a drop in performance.

The deposits keep building up and form sludge. The sludge can hamper the oil flow inside the engine. If ignored, it can lead to severe problems like malfunctioning spark plugs, valves and essential sensors. You may also find soot coming out of the exhaust if there is too much sludge formation inside the engine. Worst case scenario, you may need to replace the engine if it gets seized due to the lack of lubrication.
