Disclosed is an oil sensor system having an oil sensor including two spaced apart electrodes, a triangular waveform means, a comparison means and a signal means. The oil system is used in situ (i.e., used directly in the engine) to determine the presence of two-stroke or four-stroke oil, or the occurrence of an engine malfunction, such as a leakage of antifreeze into the oil.

A method of determining the quality of an oil comprising: placing two spaced apart electrodes in an oil to be tested; applying an alternating current triangular waveform potential to the electrodes; measuring the electrochemical current, being the induced current minus the capacitance component current, between electrodes; and comparing the measured electrochemical current with predetermined values corresponding to two-stroke oil, four-stroke oil and oil including antifreeze.
