While the CEL is on you need to take it to an autoparts store and have the code read to know what is exactly going on. Just cuzz it seems to be running fine does not mean there isn't something wrong.
Please don't forget to rate.

SOURCE: service engine light staying on
Hello tdamm...No...the service engine soon (SES) light on your yukon is not telling you to change the oil.
This is a warning light that is illuminated when there is a problem affecting the Emission system and the engines computer management (ECM) has detected it from a fault. It could be something as simple as a loose or defective gas cap. If the SES light is blinking, it's more serious....
The yukon needs to be connected to diagnostic equipment (scanner) for fault diagnosis.
You can go to autozone they will hook up an OBD II scanner to your vehicle and explain the codes to you.
Good luck...i hope this helps and will fixya up.

changing your oil should have no effect on your check engine light. You'll need to have the code pulled with an OBDII reader to and then look up the code to see what the exact cause of the check engine light is. A vehicle that sounds great while running may still have some minor issues that can become big issues if it's not addressed.
