I bought Lisle filter (63600) tool from auto zone that got mine loose. I had a replacement, but the original filter was fine so I drained it and put it back on the car. A cap wrench wouldn't touch it, just slipped. Not sure whether it was tight or lacked some lubricant on the seal. Draining the filter got the oil level down to the full mark. I'll probably change it at 5k miles. The Mobil 1 0w20 was on sale so I picked up 5 quarts and a Bosch filter.
