A system and method for measuring oil level and quality is provided. The system and method uses an alternating current (AC) to determine oil level, and a lower frequency alternating current, or a direct current (DC), to measure oil quality. The system may comprise a single sensor that is used to measure both oil quality (by providing the lower frequency alternating current or direct current) and oil level (by providing the higher frequency alternating current). Using the lower frequency AC, or DC, enables the resistance of the oil to be determined, which gives an accurate indication of the oil quality. |
