Ok, I've change a few oil filters before, but the last time on my K11, I wound up with oil flowing up my arm. Rats. So, I dunno, a plastic bag over the filter...hard to keep in place with all the turning involved. Stick a pokey thing through to let it drain more controllably? I have a variety of oil catching vessels, and a filter wrench. But at least my new diy car ramps are proving a success.
