Why is my oil light still on after an oil change?

You never want to ignore an illuminated dashboard warning light, especially if it stays on after you have already taken action to fix the problem. There are a variety of reasons your oil light may stay illuminated even after an oil change, and it’s important to be aware of possible causes. Read on for details!

Causes of a flickering oil light

If your oil light stays on even after changing your engine oil, you’re going to want to check the sensor first to rule out a malfunctioning sensor as the cause. Dirt and other particles can make their way into the oil pump, causing the sensor to falsely identify oil issues. Replacing the sensor is fairly simple, but if you don’t feel comfortable replacing the part yourself, bring your vehicle into a certified technician. The next common cause is low oil pressure. If the oil pressure is below 5 pounds per square inch, your oil light will illuminate. Although this shouldn’t happen after receiving an oil change, you’re still going to want to check the oil level just to be sure.

The final common cause of an illuminated oil light, even after an oil change, is probably the most problematic. The oil pump may not be circulating enough oil to keep the engine’s parts lubricated and functioning properly, which can in turn cause multiple engine issues. Although receiving oil changes at regular intervals should prevent this problem from occurring, parts do wear over time.
