If it it a change oil light it is telling you it is time to change the oil. There should be another light that is the oil pressure light.
The check engine light has nothing to do with changing the oil. To turn off the light, clear the PCM code using a code reader or scan tool.
If the change oil light comes on, then a person needs to change their oil. If a person changes their oil the light should turn off.
After changing oil, turn key forward to accessory mode only press the gas pedal 3 times and remove key. Start vehicle as normal and light will clear the change oil indicator.
To clear warning lights on the dash, ie: low tire pressure, change oil soon, etc. Look in the fuse panel on the dash when you open the passenger door. Hit the reset button and it will clear.
take it to a good mechanic or a ford or merc dealer and they have to clear it for you

Change your oil...
Change your oil/filter and reset the light.

oil starts out clear or light brown, as combustion gases and dirt particles accumulatethe oil darkens, if it is black it's time to change it
