If the engine light is on *after* an oil change, it means there's a separate issue unrelated to the oil change itself. Ignoring it could lead to further damage.
To address the engine light:
1. Get the code read: You'll need to use an OBD-II scanner (available at most auto parts stores) to retrieve the diagnostic trouble code (DTC). This code tells you what the car's computer detected.
2. Diagnose the problem: Once you have the code, you can look up its meaning online or consult a repair manual. This helps identify the potential cause. Sometimes, a simple reset might be all that's needed (after addressing the underlying issue), but other times, more extensive repairs are required.
3. Fix the problem: Address the issue indicated by the DTC. This could range from tightening a loose gas cap to needing significant repairs.
4. Clear the code (if necessary): *After* fixing the problem, you can clear the code using the OBD-II scanner. The light will usually go out after a few driving cycles if the problem is truly resolved.
In short: Don't try to reset the engine light unless you've identified and fixed the underlying problem that caused it to illuminate. Simply clearing the code without fixing the problem will only cause it to reappear.
