The engine can sense that the filter is blocked by the pressure differential between the oil going into the filter and the oil going out. When the If the difference in pressure is great enough, the engine will bypass the filter media to keep the oil pressure in an operational range that will prevent damage. If the oil level is low, the remaining oil degrades much quicker. Since the early 1990s, Toyota’s maintenance system was designed to annoy the driver to take their car in for an oil change, typically every 5,000 miles, or at least to check their owner’s manual to determine what services were due. But, mileage, time and fuel consumption are part of the algorithm. Mileage-based systems estimate the life of the oil based on a preset mileage recommendation that can range from 5,000 to 7,500 miles. The procedure can change depending on the model year or engine, or even the infotainment option. A tool that jumped wires in the diagnostic connector was required to reset the lights. Ford structures oil specifications around the weight of the oil. The most important thing to remember is that these estimates on the health of the oil are built around specific oils recommended by the automakers. Other maintenance items in the display are in code, that are main-codes and sub-codes to indicate transmission, belts and other components connected to a mileage interval. Since the vehicle has no idea about the specification of the oil, it is critical the oil matches the oil life monitor. If the suggested due date for maintenance elapses, the display blinks and is preceded by a minus sign.
