More than just this once.
I re-used the washer on my last car at least 10 times and it never
leaked a drop from drain hole. I know the previous owner of a 1991 model
who went over 10 years using the same washer without leaking.

The original washer on my parent's Camry is leaking a tiny amount of oil
after 13 years and 145K miles, so I will probably make sure I replace
mine at least once every 30 oil changes or so.
