I have heard you should do it everytime but I only do it if I see it leaking.

How about you?
 
depends on style.
some are washers..
some are CRUSH washers.
some have rubber.
same are plastic with rubber.

The style I always replace is the subaru style that actually crushes down.

Crush washer type = replace each oil change. Ford Flex has a rubber O-ring built into the drain plug, still on the original after 13 years.

My 2013 F150 still has the original rubber o ring. I have a spare for when it starts looking flattened out.
 
On my Honda HRV every 3rd or so oil change....Doing that on my past cars and never had a leak issue....
