I don't drive my Crossfire much, I have the original first year and I've only got slightly over 7k on it.

I change my oil about once a year or 16 months, my FSS has never gone off on it.

My '08 300C now also has a similar FSS but without a timer, just on mileage and I intend to follow it as well.

In the US, people do have a tendency to change their oil way too often and people do have different opinions on who's driving that conspiracy.
