Abstract
Fuel contamination in oil is measured by using a sensor in contact with oil whereby fuel intrusion into the oil will change the electrical, mechanical, and/or chemical properties of the material as compared to the same electrical, mechanical, and/or chemical properties of the material when in contact only with mineral or synthetic oil only. The oil quality sensor provides real-time feedback so that an oil monitoring system can actively remove contaminates and/or increase an additive package as necessary.
