An engine assembly includes an oil pan having an oil pan body. The oil pan body includes an inner pan surface defining a cavity configured to collect oil and an outer pan surface opposite the inner pan surface. Further, the oil pan includes a dividing wall disposed within the cavity and coupled to the oil pan body. The dividing wall divides the cavity into a first compartment and a second compartment. The oil pan defines an opening extending through the dividing wall. A valve is disposed in the opening and can move between an open position and a closed position. When the valve is in the open position, the first compartment is in fluid communication with the second compartment. When the valve is in the closed position, the valve blocks fluid flow between the first compartment and the second compartment via the opening.
