Don't know. If they're doing something stupid like pushing the buttons on the dash -- then it sounds like they don't know how to reset the oil life and missed it. If it hasn't been too long since your change -- just redo it yourself and make sure.
My dealer offered a synthetic change for $19.95. Cheaper than buying the oil itself -- so I took it in and had them look at things like the bumpy seat rails, etc.
Needless to say, it wasn't a good experience. Got oil all over the FRC, cap, etc. while most of the things on my list they didn't even look at or address. Best of all -- they left a bunch of parts on the binnacle above the firewall from changing the fuel line.
Hopeless. And, of course, they hit the reset button on the dash. Duh.
