I run 10W30, either Mobil 1 or Royal Purple. Both have run very nicely in my car, especially the Royal Purple. It's slightly more expensive than the Mobil 1, and I can't get it locally, which means I have to pay shipping.
I now run only Wicks (NAPA Gold) oil filters. K&N and Mobil 1 are way overpriced, and I stopped using OEM Honda when I heard they're rebadged FRAM's. I heard it from several different places. I don't know the full truth value of that, but I've only heard good things about Wicks, especially from the guy at NAPA who races muscle cars. Plus, they're very moderately priced.
