ABSTRACT:
An engine oil heater suited to use with an engine having an oil fill port in fluid communication with an oil reservoir that is adapted to contain a quantity of oil. The engine heater generally includes a coupling member operable to engage the oil fill port and a heater element interconnected with the coupling member and having a sufficient length such that the heater element is adapted to be at least partially immersed in oil. A temperature sensor is positioned to measure a temperature and a first electrical connector is configured to engage a second electrical connector. The first electrical connector is electrically connectable to the heater element to provide a flow of current and a control circuit is operable to vary the flow of current to the heater element in response to the measured temperature.
