matter of fact, i need to think about that myself. i've got a free-tires-for-life deal that depends on my having all my oil changes and service done at the dealer. they stickered it for 3k last time till i showed 'em the book and 7k. they will, of course, up-charge me for synthetic but i believe that what the book says. the car tells me i'm now due, according to the odometer trick y'all showed me, in 1700 miles which will be close to 7k.
just checked and it's lookin a little dirty.
did y'all know they did away with the transmission-fluid dipstick?? change it at 80k and that's it "for life". amazing how little i know about this thing.
