The financial cost of ignoring this issue invariably multiplies from a simple oil change to a complete engine rebuild. Accompanying this visual change is a distinct smell; while old oil smells acrid, the combination of oil and coolant often carries a slightly sweet or tart odor that indicates the presence of ethylene glycol or water.

The Visual Test and Smell Conducting a visual inspection is the simplest first step in diagnosis. Drivers might also notice a sudden drop in oil pressure, a burning smell emanating from the engine, or unusual knocking sounds that indicate the lubrication film is breaking down due to the presence of water.
