Oil change, about 1000 miles late. Switched to using Mobil 1 5w30 this time around; I don't suspect I'll see much of a difference, but the general consensus I've seen is that Mobil 1 is a "better" oil (without much in the way of empirical evidence).
Also, I switched to using a 3000GT VR-4 OEM oil filter; it has a larger capacity than stock, and because it's shorter than the original filter, it clears exhaust much better than before. This will be far more important once I've gone to a 3" exhaust.
