Normally, an oil change takes about 1/2 hour.  But, for some reason, this one was taking much longer.  And, usually when that happens, it means the there is something wrong with the car.  I was a bit concerned until the garage manager asked me if I knew how to reset the maintenance indicator. Apparently, the mechanic had been trying for over a half hour to reset the maintenance indicator.  Since it was getting late and I wanted to go home, I told them not to worry about the maintenance indicator as I would reset it my self.  They were elated and I cashed out to head home.
