The oil of the car is an important yet underrated aspect of maintenance. Most people consider changing the oil only for better mileage. However, there are many other reasons to get fresh and clean oil. It can improve the overall efficiency of your vehicle and protect the engine. But, how do you know it’s time to get your car into the shop for an oil change? Here are some signs you should look out for.

A knocking noise from the engine

The oil used in the car acts as a protective layer between multiple engine parts. It prevents the brushing of different metal parts and keeps the engine quiet. If your engine is being loud or creating a knocking sound, it’s time you take it into the shop for an oil change. Lack of lubrication can cause severe wear and tear and reduce the performance of your vehicle.

The oil is dark and dirty

The oil used in cars should be translucent and have a slight shade of amber. Over time, with use, the oil begins to collect particles and becomes dark and dirty. This is why it is important to check and replace your car oil once a month. Replacing used oil ensures the car remains in good condition and performs at its best.

Excessive exhaust fumes

One of the things to watch out for is the exhaust fumes. New cars typically do not release any visible exhaust fumes. In case your vehicle is releasing fumes, it is about time to take it to the shop for a quick oil change. Why? Because this is usually a sign that the motor oil has become too old or dirty to function properly.

Check engine light

This is obvious. Most cars come with a light that illuminates when there is a problem with the emission control system. If this light switches on, it’s likely that your vehicle is polluting the air beyond limits. It means you need to change the oil or check the engine. You can also check the dipstick to see what is going on with the oil inside and make changes at the right time.
