- I had no issues with re-using the Drain and Fill Plugs.

- I usually TIGHTEN the bolt a tiny bit (yes tightening it), then turn CCW, it came right out. Also I used 6-point socket for the Fill Bolt. You don't want to use 12-point socket for the Fill Bolt.

- At 120K or so, I will drop the pan and replace the filter. I was too busy and only interested in doing a drain and refill at 84K.
