Each filter package comes with full set of orings.
I tried to save dirty fingers by doing small orings every 2nd time, but since we change oil with more than a year intervals, I could never remember if I replaced them last time.
Get rubber gloves, a cardboard where you can put filter assembly on and do it every time.
Than on couple of cars I bought used I noticed "extra crispy" filters.
The cars suppose to have recent oil change by selling dealer.
I don't think they cheated on oil change as that would be easy to notice, but nobody can detect skipping filter change with oil change.
