An oil pump for a vehicle engine. The oil pump includes an oil pump housing and a gerotor. The oil pump housing includes a cavity that defines an inside diameter. The gerotor is positioned within the cavity, is rotatable relative to the housing, and defines a thickness and an outside diameter. The distance between the inside diameter and the outside diameter is non-uniform across the thickness.
