ABSTRACT:
A method for detecting fuel leaking into an oil pan containing oil which is used to lubricate an internal combustion engine utilizes a plurality of sensors. The method includes the step of measuring a plurality of parameters of the oil using each of the plurality of sensors to create measured values. A fuel leakage value is calculated incorporating each of the measured values. The method then determines when the fuel leakage value exceeds a predetermined value.
