1. A method of monitoring oil consumption in a gas turbine engine, comprising the steps of:

  • sensing reservoir oil level when the gas turbine engine is not running;

    sensing reservoir oil temperature when the gas turbine engine is not running;

    sensing reservoir attitude when the gas turbine engine is not running;

    determining current gas turbine engine system oil quantity based on at least the sensed reservoir oil level, the sensed reservoir oil temperature, and the sensed reservoir attitude;

    determining that a predetermined event has occurred;

    automatically calculating an average gas turbine engine system oil quantity after the predetermined event has occurred; and

    determining gas turbine engine system oil consumption rate from a plurality of calculated average oil quantities.
