Lost count of how many oil changes I've done over the years, but this was my 3rd on the audace. Drained oil, dropped filter into drain pan, gave it a few minutes, put plug back and torqued new filter into place. Filled with about 3 liters and fired it up - result, oil everywhere - all over the garage floor, all over the ATV lift, all over my tools on the floor. I stupidly didn't check the old oil filter. It's rubber seal had come adrift and was still inside the sump housing, so now I had two oil seals in there which of course blew apart and dumped 1.5 liters of 10w60 (about $37 CDN). Fortunately the filter was OK but my ego is severely bruised - grrr - lesson learnt the hard way
