dum8ss1236 mentions that he's never seen a drain plug washer on other vehicles. I have never seen one without one. I don't understand how there could be a good seal without one.
dum8ss1236 - Since the 4Runner needs a washer, you'll need to put one on (even though you'll lose a some of that synthetic oil).

Some people call it a crush washer but it really isn't. A crush washer is more like the washer you would see on a brake line that actually compresses and should be replaced.
