    Abstract: Oil pan assemblies and methods of draining oil pans are disclosed. An example oil pan assembly includes an oil pan defining first and second sumps. The first sump has a first lower surface and the second sump has a second lower surface. The second lower surface is elevated along a vertical axis relative to the first lower surface.
