I found a suitable 36 mm socket online I think at partsamerica.com, and filters I hit up minimania. I didn't have any trouble at all changing oil or the filter. I read some walkthroughs that mentioned trouble reseating the new filter. I dabbed a bit of new oil on the new filter and it sat right down and the canister threaded in no problem. I had no trouble getting at the canister with a regular craftsman 1/2 in drive ratchet and the cheap socket I got. Pretty easy job, 20 min start to finish.
