Why Does the Engine Light Come On After an Oil Change?
The engine light coming on after an oil change is a common phenomenon, and it’s often due to a few reasons. Here are some possible explanations:
-
Loose Oil Cap: A loose oil cap can cause the engine light to come on, as it’s not properly sealing the oil reservoir. This can lead to oil leaks and other issues.
-
Incorrect Oil Type: Using the wrong type of oil for your vehicle can trigger the engine light. Make sure to check your owner’s manual for the recommended oil type and viscosity.
-
Oil Filter Not Replaced: Failing to replace the oil filter during an oil change can cause the engine light to come on. The oil filter plays a crucial role in cleaning the oil and preventing contaminants from entering the engine.
-
Oil Level Not Checked: If the oil level is not checked and adjusted after an oil change, it can cause the engine light to come on. Ensure the oil level is at the recommended level to avoid any issues.
-
Other Issues: In some cases, the engine light may come on due to other issues, such as a faulty oxygen sensor, loose gas cap, or worn-out spark plugs. It’s essential to diagnose the issue to ensure it’s not a more serious problem.
