I think the conclusion is in. No one here re-uses crush washers
These have a good chance of leaking if reused. But for some reason I like themI dont reuse crush washers.. although the hyundai style flat alum. washer is fairly reusable.
Now the subaru actually crushing style. I would never reuse unless its an emergency type situation.
In part because the crushing makes it very easy to know how much to tighten the drain plug.

Is that how they spell it in CA?warsher
I also have the rubber O-ringed one for my Hyundai. Best $8 I have spent on Amazon, 7 years and never a leak.If I ever owned a vehicle that had the multi-layer sheet metal type (like on spark plugs) I might be tempted to replace them every time or at least every other time:

On my ag equipment that have solid copper gaskets, I reuse them for many years (annual oil change).

My vehicles have always had drain bolts with built in/attached rubber o rings and I reuse them for many years.

I dislike and do not use plastic or fiber drain plug gaskets.
blasphemyI'm more likely to reuse an oil filter than the Crush Washer
Oil filter or crush washer?Fwiw I change mine out every handful of uses.
Enough.Again, the argument “nothing bad happened” is weak. Specious.
You cannot define best practice on the basis of “nothing bad happened”.
Look, we are talking about amateurs changing oil. Low consequence. Nothing bad will happen with a drip. Further, not a lot of people in this group who have access to, or follow factory maintenance practices.
Deriving principles, or even simple failure analysis, from the behaviors of this group is both flawed and pointless.
Amateurs take shortcuts. I get it. No worries. You do you. What’s the worst that happens, a few drips?
But that will not ever convince me it is OK to take those shortcuts.
I have a couple of cars that run hydraulic suspension systems at 2,700 PSI. They use o-rings to seal. Mercedes requires those o-rings be replaced every time. A leak there can cost you dozens of hours and thousands of dollars in failed components.
I do not take shortcuts. I do not engage in amateur practices.
If they all did this - we’d not make 150 replies on a washerI love that the drain bolt gm uses has a gasket in the bolt head lasts forever. Wish every oem did that but you can likely find an after market bolt so you never have to use a crush washer again.
I dowt it ...Anyone used a dowty washer?
