Facts About Black, Dirty, and Sludgy Motor Oil

Sludgy Motor Oil

Motor oil, much like all the other components and systems in your vehicle is quite susceptible to aging and common wear. When the motor oil in your vehicle ages and becomes extremely dirty looking, it is important to change out the sludgy motor oil so as to avoid damage to your vehicle’s engine. Here at Auto Clinic of Franklin our team of highly skilled professionals wants to help our valued clients to understand why dirty, grimy oil can be detrimental and very harmful to your engine. With that said, here are some important facts you need to know.


Sludgy motor oil begins to make its presence known when a vehicle owner fails to have a proper oil change performed in a significant period of time on their vehicle. In addition to motor oil lubricating the important parts and components within your vehicle’s engine, it is also responsible for cleaning up various contaminants and particles that may have made their way into your vehicle’s engine. When this occurs, the efficiency of your motor oil begins to decrease as the ongoing buildup occurs. Over time, the oil in your vehicle will collect sludge and a wide range of particles requiring a change in motor oil. If, however, you fail to change out the motor oil in sufficient time, it will begin to take on a very black, gritty and grimy appearance.


In addition, sludgy motor oil is also caused by a dirty oil filter. The primary function of the oil filter is to filter out particles and contaminants that are located within your vehicle’s motor oil after it has completely cycled through your vehicle’s engine. If this oil filter is not changed routinely and in a timely fashion it will no longer have the capability of removing the particles and contaminants thereby causing them to remain within the motor oil itself.



It certainly goes without saying that motor oil that is grimy and black in color cannot benefit your engine. Rather, the grimy oil not only fails to properly and effectively clean and lubricate your vehicle’s engine, but will, over time, turn into a deep, dark sludgy motor oil. This grimy motor oil when cycled through your engine can result in a significant amount of damage to your vehicle.



If the oil in your vehicle appears black and grimy, don’t delay in reaching out to the skilled technicians here at Auto Clinic of Franklin to schedule your oil change as quickly as possible.

However, when you have an oil change performed, all of that dirty, yucky sludge is cleared out of your engine and is replaced by fresh, clean oil that will contribute to a higher performing engine and a much smoother and more comfortable ride. The sludge can be quite damaging to your engine which is why routine oil changes are so important.
  • Prevents engine overheating – Clean oil lubricates the engine parts and avoids friction. When friction is present it will create heat that will trigger the sensors in your engine and ultimately alert cause your engine to overheat. When you have a sufficient amount of clean oil in your engine, any friction and overheating are minimized and prevented over time.
