Where is the oil plug on a 1996 Pontiac Grand Am?

The oil drain plug on a 1996 Pontiac Grand Am is located on the bottom of the oil pan. To be more precise, it's underneath the engine, towards the front of the vehicle. You'll need to be underneath the car to access it.

Because there are variations depending on the specific engine (you'd need to specify the engine size, such as a 2.4L or 3.1L, for a more precise location), this general description is the best that can be given without that information. A repair manual specific to your Grand Am's year and engine would show the exact location with a diagram.
