Filter arrived pre-oiled and ready to install. The quality of the filter is noticeably better than the disposable alternatives. FYI - The way the filter sits in the filter box for the STS is a little concerning, since the rubber edge of the filter is exposed on the bottom, but not the top. I removed the box from the car to do the replacement. It would be hard to get the filter in correctly, otherwise.
