Oh, and I had mine changed at 8448 miles when the monitor hit 15%. Last Wednesday, I hit 39,000 miles (and 15%) and I had it changed for the 5th time. Starting with this change, though, I think I'm going to change it every 5,000 miles no matter what the monitor says. That way I can remember to rotate the tires w/every oil change.

 

With synthetic, I would have no qualms about 10,000 mile oil change intervals, keeping tire rotations at 5000. Both numbers very easy to remember.
