1. A lubrication distribution system for an engine, the system comprising:
a source of lubricant for the engine; and
at least one feed line fluidly connected to the source of lubricant, the feed line comprising:
a wall defining a passageway and an orifice, the feed line terminating at the orifice, wherein lubricant flows through the passageway and exits the feed line through the orifice; and
a heating element contained substantially within the wall of the feed line and located at or directly upstream of the orifice, the heating element selectively activated to heat the lubrication flowing through the passageway and exiting the orifice.
