I have a 2011 mustang with the 6 cylinder how do i reset the light that says change oil when im done

 

Should be in your owners manual.

1. Press and release the SETUP control to display OIL LIFE.
2. Press and hold the RESET control for 2 seconds and release.
Oil life is set to 100% and OIL LIFE SET TO 100% is displayed.
3. While OIL LIFE SET TO 100% is displayed, if a lower oil life start value is desired, press and release the RESET control to reduce the start value. Each press of the RESET control reduces the value by 10%.
Oil life start value of 100% equals 7,500 miles or six months.

 

Yep, read the duh-rections!

I'm kidding... I had to look up a few things too!
