I WILL be changing my oil, but I am only at 600 miles. I plan to change mine every 5K or less. So looks like I will be doing two changes between dealer changes.
I think 15K(or so) is ridiculous for an oil change. Yeah, they lubricating properties of the oil is still good at 15K, but the issue is the additives in the oil that get consumed....plus fuel contamination, etc.
I will be changing mine for sure every 5K or less. I can't help you out with parts or procedure yet....
If you do find something...such as procedure and parts numbers (oil filter, etc.), please share.
