Chris,
I don't think anyone can predict the future, but I would say that
you're ok at 7500 miles with a synthetic oil.

My '92 100CS has 77.5k miles on it, I use synthetic oils only, and I
have the oil changed on a 6k mile schedule. Of course, now that I've
read Jim Griffin's post, I'm thinking about extending it. Hell, I burn
through a quart every 800 miles, so the stuff IS fresh! ;)
