On my 2006 RT I've got the computer display thing. At the end of each ride I stop in the shop, in neutral engine idling and press the button until it displays "Oil" and a big check mark. That's close enough for me.

OOPS! Mea Culpa Mea Maxima Culpa. I'm sorry to step on this Oilhead thread with a Hexhead comment.
