A check engine light (CEL) primarily signals issues related to your vehicle's emission systems and could indicate a wide range of concerns from minor to serious problems, including sensor failures or engine misfires. It's not directly linked to the need for an oil change. However, neglecting regular oil changes can lead to significant engine problems which might trigger the CEL. For instance, old or low engine oil can cause poor lubrication, overheating, or increased friction among engine parts, potentially leading to performance issues that could activate the light. It's essential not to dismiss the CEL, assuming it's just a reminder for routine maintenance like an oil change. Instead, it's advisable to use a diagnostic tool or seek a professional mechanic's assistance to accurately identify and address the issue. Regular maintenance, including oil changes, is crucial for vehicle health and can preemptively address issues that might otherwise turn on your CEL.
