Abstract: An apparatus and method for determining lubrication contamination or deterioration in an engine or a lubricant system of an engine can include at least one sensor provided in the lubricant system. The sensor can sense an aroma of a lubricant or the air around the lubricant to measure a chemical composition or an aromatic. The sensed chemical composition or aromatic can be compared to a baseline or threshold to determine a particular contamination type or deterioration level of the lubricant.
