how do i drain oil from a ford fiesta engine ??

Just buy a haynes manual.
Take off the oil filler cap.
Or take out the drain plug on the bottom of the engine sump.
Make sure you have a drain tray below.(cut a hole in the side of an oil can and lay on its side).
Change oil filter at the same time.
Make sure you put some more in before you start again.
