Got the old oil drained, and refilled, along with a new filter. That filter was a bear to get to!! Luckily I was able to unscrew the old one with my hands (death grip from my fingers).

layful:
I used a 6mm (thanks commanderjjones) allen wrench to remove and replace the drain plug, after thoroughly wiping it and the copper washer down. I'm not sure how to check the torque setting on these, but I snugged it up by hand pretty good.
