Try this. Turn the key on and with the engine off fully depress and let go of the accelerator pedal 3 times within 5 seconds. If the "Change Oil Soon"light flashes it has been reset, if not try the procedure again. Don't forget to turn the key back off when done. I also use synthetics in my vans and since the oil life monitors can't tell the difference between conventional and synthetics you will get the change oil message again a few more times before it is time to change the oil again. Depending on how long you plan to keep the oil in your engine,( I leave mine in 10,000 to 12,000 miles with just a filter change and top off, half way through the cycle) you'll have to reset the message at least once or twice during the time you have the synthetic in the engine before it is time to change it out.I find, depending on certain conditions, my oil life monitor comes on anytime between 2600 to 3500 miles. So I end up resetting my light 2 to 3 times during the time I have my current synthetic in my engine.
