ABSTRACT:
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.
