I am stationed in Germany and just had my oil changed as well. The dealer said the oil change schedule is set by the build date of the vehicle. Mine was built in Feb. and showed oil change due with 2600 miles. The stupid part of this all is the dealer dosen't know how to reset the light yet for the oil change I had done. He just recieved his first Journey for the lot a few days before my service and is waiting for the FSM's to arrive so he can figure it out.
