In ~300k km worth of diy oil changes, I’ve yet to change a crush washer, and yet to have a drain plug leak.
I always replace them on friends’ Toyotas, because they seem more important, but on every car I’ve owned it hasn’t mattered. And if you take the least amount of effort to google “how to change oil on ________” (fill in the blank for your year, make, model), some forum or video will probably tell you exactly what steps to take, including whether or not changing a washer is necessary.
Costs me 15 cents per washer delivered, why bother risk it? The world doesn't need more cancerous used motor oil on the ground.
After downloading a service manual and doing many things myself it became very apparent that mechanics barely bother to do work the right way despite it coming at virtually zero extra effort.
It's quite rare to see them use a torque wrench on many bolts and if you ask them why "they know it by feel", cool, but why not use a torque wrench to the proper specs anyway? It's not any harder.
