gauge says change oil soon. just changed the oil
how do i reset oil sensor after an oil change on 2004 Buick LeSabre
While the display on the DIC tells you "Change Oil Soon" you hold down the reset button until the message goes away. It may take 5 to 10 seconds.

Check your owners manual- it has the specific instructions on how to reset the oil life monitor.
Usually the garage that changes the oil does this. If you do your own, midas will reset it for you,
