These vehicles use systems that inform the driver when an oil change is needed. This indicator should be reset after every oil change. There are some variations to the reset procedures depending on the make, model, year and the vehicle's optional equipment. The vehicle's owner's manual should be consulted because it will help identify the system used on your specific vehicle, engine and option combination.

One version of the system is called the Change Oil Soon Indicator. It predicts when the oil's remaining life is almost up. The system predicts remaining oil life using travel distances, coolant temperature, engine RPM, and vehicle speed inputs. This indicator alerts the driver to change to oil on a schedule consistent with the vehicle's driving conditions.

Another variation is called the Oil Life Monitor. The oil life monitor shows the percentage of the oil's remaining useful life. The system predicts remaining oil life using travel distances, coolant temperature, engine RPM, and vehicle speed inputs. This monitor should also be reset after every oil change.
