Methods and systems are provided for preemptively heating engine oil prior to an engine start using an inductive heating mat. In one example, a method may include coupling a magnetic field between a primary coil housed in the inductive heating mat and a ferrous oil pan to inductively heat engine oil contained in the oil pan. While maintaining engine oil temperature above a threshold temperature, heated engine oil may then be circulated through engine components to warm up the engine prior to engine start.
