How To Reset The Oil Life Percentage On A Honda Accord

April 8, 2011

Very little information other than forum discussion is available on Honda's "maintenance minder" system for suggesting oil changes. From the answers supplied by moderators it seems that Honda uses a system similar to GM's OLS, which keeps track of  the type of use a vehicle encounters to then project the quality of the motor oil.

If you want a definitive answer to this you can rely on the Honda owner's manual which states, "based on the engine operating conditions and accumulated engine revolutions, the onboard computer in your vehicle calculates the remaining engine oil life and displays it as a percentage," so much for the value of explicit information.

What this means is that a series of short trips in cold weather will shorten oil life when compared to highway driving in a warm climate. Conditions that are monitored in order to arrive at engine oil life are said to be engine temperature and load, total miles driven and trip length, as well as vehicle and engine speed.

The maintenance minder prompt on the dash is pretty clear cut since it appears as a percentage in the instrument cluster. It is accessed by toggling through different displays with the reset knob that you use to display and reset the different trip indicators.

Here is the method for resetting the oil life percentage back to 100% after completing an oil change (good for 2006 -2011 Honda Accords):


Turn the key to the "on" position (be sure to not start the vehicle)


Press the Select/Reset knob used to access the odometer and trip readings until it displays the oil life percentage


Press and hold the knob until the oil life percentage begins to blink


Release the knob


Depress the knob again until the oil life percentage resets to 100%
