Oil Changes - The unwritten step?

Hi guys, I've been searching like mad through google to get a definitive answer, but ended up with more questions...

Here goes:

Basically I've had my '02 Liberty since May 21, 2011. I've changed the oil every 4k miles (though they recommended 5k). Well after my last oil/filter change I would occasionally have the engine lamp ding and stay lit for a few seconds then go out. Oil levels were fine, so I wrote it off as a possible sensor issue since it didn't stay on nor did I hear any knocking while the light illuminated. Well Friday I swung by my mechanics to get a second opinion on another minor issue I was having. I mentioned the oil lamp issue, he asked if I performed a reset after the most recent oil change.

I said, "no as I thought I needed an OBD tester to clear codes." (My old Bronco needed one)

He said that I didn't need one and it could be done from the dash. He turned the key to "ON" then held down the trip odometer and all the gauges cycled through. He said i should do with with every oil change.

Well when I got home I thought I'd learn a little more about this, but everything I've seen on the net says I should turn the key to "ON" had hit the gas pedal 3 times within 10 seconds. So with that I'm a little more confused as to what the trip odometer button cleared.

So basically is there a un-written step for clearing codes now with oil changes?

Your mechanic should move into Sales....his talents are wasted where he is at the moment.

The trick of holding down the Odo meter trip button while switching on the ignition is merely to test that all the lamps illuminate and that the gauges are functional.......nothing more than that.

Lol pretty much yep. All that does, is do a self test of the instrument cluster, and on some chryslers at least, will display what software version the cluster is running. Apparently your mechanic is just that, a mechanic. Go seek an auto technician, as there is a difference. Mechanic=old days of throwing parts at a vehicle till its fixed. Technician=like a doctor on a vehicle, but we dont do trial and error like doctors do,lol.

Your engine light is supposed to come on when you turn the key on, and first start the vehicle, as a self test, then it should turn off. If it stays on, then there is a problem. Oil changes are not directly related to the engine light.

Now some vehicles, particularly GMs, but many others as well, have oil life monitors, and require reset after an oil change, and they are not tied to the engine light in any way.
