had my oil changed a week ago but my oil light still comes on when i stop but goes off when i drive its a 2007 ford five hundred

Oil pump possible. Check oil level of course. Go back where you had it changed. It builds pressure while moving sounds low. Any noises?

Have ever gotten an answer for this

I also am having the same issue with same make and model. I took my car back after a week and they stated everything is fine and now a higher pitch noise as i drive over 35 mph and they said of cours everything looks fine so no answer as of yet
