Howdy, I'm new to the Forum, but this is my fourth Explorer.
Truthfully, I liked my '01 a whole bunch better than the '06... It ran better, got twice the milage, this one can't pass a gas station. Probaly not too bad at a buck a gallon, but really not fun at three bucks. And the '01 was much more fun to drive. However. As I approached 4500 miles in this one the change engine oil soon light came on. At 4650 mile the change engine oil required light came on. Changed oil. Can't figure out how to reset the stupid light..
The Garage couldn't help. They said, they heard it was hard. Anybody got a clue? Thanks

You can try disconnecting your negative cable from the battery. This works to clear stored CEL & SEL codes.

I can't garantee it will work but its easy & free :)
