The crush washer helps ensure you don't ruin the threads on the pan by over tightening. It also helps keep the bolt from loosening between oil changes. Since the washer is "crushed" (hence the name) when you tighten the bolt, you're supposed to replace it at every oil change. If you use the same washer over and over again, it's not doing it's job.
