I do 10k OCIs in my Camry with M1 EP; I do a lot of highway and a fair bit of in-town driving too, though very little is under 20-30 minutes so the oil almost always has a chance to warm up/the car is rarely short-tripped. 10k ends up being roughly every 6 months for me, and the oil is always almost exactly on "full" and of a rather light color. It's now rated at 20k, so 10k seems well within its capabilities, at least for a non-DI engine that isn't short-tripped.
