I change the oil on mine once, maybe twice a year at most.  If I bought even only 50 washers I'd never live long enough to use them all.
Also, they're re-usable.  I never had a leak re-using them, and if at some point oil would start to seep out, I'd replace it at the next oil change.  Having said that, if I had one handy during the oil change I'd replace it.  But it's just not that high on my priority list, so it's not on my mind when I buy oil and filters.
