Definitely recommend to cut that factory interval in half (change every 5k) and either just before or after each track day. Oil and a filter is cheap!
Wooaah! 5k? Who knows what could happen to that stuff while sat in the sump?

Fully synthetic means it ages really well, and it doesn't break down if you roast it on a hot day at the track.

It is designed to collect wear and combustion products and carry them back to the sump so that the oil filter can remove them.

Change the filter more often if you're worried.
