The engine light on your dashboard is one of the most frustrating and mystifying things that can happen to a car owner.

In this article, we’ll explore the reasons why your engine light might be on after an oil change and what you can do to address the issue.
What Does the Engine Light Mean?
The engine light, also known as the “check engine” light, is a warning indicator on your dashboard that illuminates when your car’s onboard computer detects a problem with the engine or other systems. It’s a generic term that can refer to a wide range of issues, from minor problems like loose gas caps to major problems like engine failure. When the light comes on, it’s usually accompanied by a code that can be read by a mechanic or scanned by a code reader.
Why Does the Engine Light Come On After an Oil Change?
There are several reasons why the engine light might come on after an oil change. Here are some possible explanations:
Loose or Faulty Oil Filter
One of the most common reasons for the engine light to come on after an oil change is a loose or faulty oil filter. If the filter is not properly secured or is damaged, it can cause the engine light to come on.

Incorrect Oil Type or Amount
