What torque does the manufacturer recommend, do you have a torque wrench ( or access to a workshop that has one ) ?
This!! /\Very much, this!!
Not tightening it up enough could have catastrophic consequences!
Find out what it should be torqued up to and do it to that!

I've learnt one more way of getting a stuck threaded thing out of a hole which is great.
I should probably point out, the only reason it was as manageable as it was, is due to the soft aluminium oil drain/sump plug which was easy to drill and chisel. A harder fastener would have been a bit of a nightmare.ReverendCounter said:
Just to update this, used a slightly different approach:
- drilled pilot holes as indicated, red
- enlarged the holes with a bigger bit, yellow
- removed about 1/3rd of the flange with a standard 1" sharp wood chisel I had to hand, green
- used a drift and a decent sized hammer to rotate + unscrew, cyan
Didn't need to use any heat but that could well have done the trick in the first place, as advised.
Didn't put grease on the threads/o-ring which probably led to the seizing.
Didn't put grease on the threads/o-ring this time round either due to the excitement.
What will I do differently next time? grease the threads/o-ring and not drill into the engine casing when I'm trying to un-seize it next oil change.
