The oil drain plug on a 1994 Ford Mustang is located on the
bottom of the oil pan. The oil pan is the metal tray underneath the engine. To be more specific, you'll find it on the
driver's side (left side) of the engine. You'll need to get under the car to access it. It's usually a bolt, and you'll need a wrench or socket to remove it.
Important Note: Before you start, consult your owner's manual for the exact location and the correct size of the drain plug. There are variations between engines (e.g., 4-cylinder vs. V6 vs. V8). A picture in the manual will be incredibly helpful.
