Abstract

See full text

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. The oil pan assembly also includes a siphon tube extending from an inlet positioned in the second sump to an outlet positioned proximate a drain hole in the first sump. The siphon tube is configured to automatically transmit oil from the second sump to the first sump upon oil being drained from the drain hole.
