if you get the oil analysed before you change it you will be able to know how much longer your oil can last. they wont advertise 25k miles if it hasnt been proven.

i have seen mobil's synthetic oil been good for 15k miles. it was analysed every 3000 miles and the filter was changed only oil added was to replace the oil lost while changing the filter. this was tested by members on another forum using a daily driven 98 ford explorer with a 4.0 ohv or sohc (i cant remember which motor) and the oil was still good when he decided to change it.

i was just letting you guys know of another place to buy the synthetic oil from not telling you when to change it.
