Yes it is a good time. I would have done it 20K miles ago...
I would do a search on this topic (but this forum is not the best on this topic). Since I test my oil, Amsoil, while 99% on this forum does not, you can go way over 7500 miles with Amsoil oils and be fine. Some other synthetics no way. Plus it depends on what you want. It is oil longeveity, oil performance, protection.....
Side not when something is called a synthetic you need to know what you are getting, what is a real synthetic and how it performs in your car. Example, Walmart Synthetic oil is not even close to Amsoils (for example). Also Lexus is WAY behind the times on oil duration.
