A method of monitoring oil in a vehicle having an internal combustion engine is provided. The method includes measuring a sump temperature of the engine and measuring a power output of the engine. Oil consumption is calculated as a function of the measured sump temperature and the measured power output. Remaining oil life is calculated as a function of the calculated consumption. The method may include alerting a receiver of the calculated remaining oil life.
