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.

Precisely.
Besides, buying crush rings for the next couple dozen oil changes for a 20 year old car with 100+K on the odo just seems presumptuous, risky even.  Why tempt fate?  Allow me my harmless superstitions.  I think our sponsor’s doing just fine without me buying a stack of his crush rings.
