2009 Toyota Camry Solara oil change interval

I have an 09 Camry with 200k miles of which I take very good care. I have always used fully synthetic oil. How often should it be changed? Thanks!

You have made 200000 miles and you just now are asking how often to change oil? I guess that the schedule you have been using works. Besides that is in is your manual and I would go by the severe schedule now.
