What are the symptoms of motor oil contamination in a BMW? Motor oil lubricates the components of an internal combustion engine. By doing so, it minimizes friction within the engine and thus enhances its efficiency. Moreover, motor oil also absorbs the heat generated due to the process of internal combustion and thus keeps the engine cool and prevents engine overheating. It also protects the sensitive components of the engine from different types of contaminants and helps to prevent rust and corrosion. Besides, it also acts as a gap filler and improves the performance and efficiency of an internal combustion engine. However, motor oil is subjected to the intense heat generated due to the process of internal combustion as a result of which it degrades over time. Degraded motor oil loses its property of lubrication as a result of which friction within the system increases. Higher friction within the system would affect the performance of your BMW. Moreover, heavily contaminated motor oil negatively affects the efficiency of your vehicle. So, symptoms of motor oil contamination in BMW should not be neglected. Evaluate the quality of motor oil used in your car on a daily basis and replace it if necessary.
Motor oil contamination in your BMW Heavy contamination does affect the lubrication ability of motor oil in an adverse way. So, the color of the motor oil used in your BMW should be inspected on a daily basis and if it is gray or black, then you should replace it as soon as possible. Moreover, symptoms of heavy contamination of motor oil in your BMW should not be neglected. If the performance of the engine declines or if the engine of your BMW makes unusual noises, then it shows that motor oil is heavily contaminated and needs immediate attention. Symptoms exhibited by the heavy contamination of motor oil in your car should not be overlooked. Replace the contaminated motor oil as soon as possible to keep the engine in working order.
Dark motor oil: Motor oil of your BMW is amber in color. However, the deposition of different types of contaminants like coolant, water molecule, dust particles, metal particles, and other types of contaminants makes the motor oil dark in color. Such kind of heavily contaminated motor oil could kill the engine of your BMW in the middle of nowhere. So, use the dipstick to measure the level of motor oil contamination in your car. If the motor oil is dark in color, then it is a clear sign of heavy motor oil contamination. Heavily contaminated motor oil should be replaced immediately.
Check engine light is on: It is another important warning sign of heavy motor oil contamination in your BMW. As mentioned earlier, motor oil lubricates the engine and also stabilizes its temperature. However, it loses its ability of lubrication over time and should be replaced after an interval of about 3,000 miles. However, if you skip an oil change, then the performance of the engine would decline significantly. Moreover, it could also trigger different types of mechanical malfunctions in the engine. If the engine control unit detects any kinds of errors in the system, then it would turn on the check engine light on the dashboard of your BMW.
Unnatural engine noise: The motor oil acts as a layer of protection and protects the sensitive components of the engine from rust and corrosion. Moreover, it also minimizes friction within the system as a result of which it prevents major physical damages to the engine components. However, if the motor oil loses its ability of lubrication and additive nature due to heavy contamination, then it couldn’t protect the engine of your BMW. So, if the engine of your car is making unnatural noises,
then it is a clear symptom of heavy motor oil contamination. Replace the motor oil of your BMW as soon as possible to protect the sensitive components of the engine.
Wrapping up Skipping an oil change could kill the engine of a vehicle. The presence of heavy contaminants could damage the sensitive components of your car. So, a timely oil change is really necessary to prevent premature engine wear in your BMW. It is very simple and inexpensive. So, the appearance of different types of warning signs which shows that motor oil of your BMW is heavily contaminated should not be ignored. Efforts should be made to replace the heavily contaminated motor oil as soon as possible.
