I just purchased an 04 with 27k miles for my son. The FSS was stuck at -6600 although there was a Mobil 1 change reminder on the winsshield which was just about up. Is the defualt oil change really 7K? I know it will adjust but that is the default?
I could not find any mention of rear riff. fluid changing in the manual. The shop I use said their computer showed fluid replacement at 30k, is that accurate?

Thanks,
