An oil maintenance indicator for recording one or more parameters indicative of when an engine oil filter has been changed. The maintenance indicator includes a sensor that measures oil pressure of an engine at start up. A comparitor compares an output provided by the sensor to known parameters to determine whether the oil filter has been changed. A recorder coupled to the comparitor records one or several parameters indicative of when the oil filter has been changed.
