I'm doing a poll as to what interval most folks are going to have the oil changed in their Crossfire. 5k or 7k intravals???

I opt for 7k.

For years I used to change oil every 3k miles but increased it to 5k without any ill effects using 10W/30 year around. DC recommends 7k. I'll do two oil changes and see how the oil looks before I'll think about going to the 5k cycle.
