I've never had that problem with the aluminum drain bolt washers I've used. I can see some slight marks on them from the compression, but they don't flatten out at all. I torque my drain plugs to specs.They flatten out over time. I’ve seen it. Some of them get so flat that you have to cut them off.
Depends on the material. I think some of the aftermarket replacements are harder than the original ones. But I have had to cut off my share of deformed drain plug washers....many times.I've never had that problem with the aluminum drain bolt washers I've used.

The ones I've used are appatantly not that soft. The aluminum drain plug washers that came from the factory on my motorcycles have never crushed down enough to deform them visibly. Guess if I miced them it might be a few thousands of an inch, but nothing requiring replacement and never locking the washer on the drain plug.Depends on the material.

Did 5 quarts drip out before you replaced the washer, or were they lost in the process of changing it? I've had instances in which I had to replace a crush washer not long after I changed my oil and probably lost no more than a half quart of oil each time, probably more than I needed to.I had a 2019 Mazda 3 hatch. It did this exact thing. I unfortunately lost the full 5qts of Mobil 1 ep, but I replaced the crush washer, and it solved my issue.
I truthfully didn’t care to try to catch it, or try to slowly top off until it was full again. Easier to just dump, and replace since I did it laying on the ground with the car on ramps.Did 5 quarts drip out before you replaced the washer, or were they lost in the process of changing it?

Can confirm. Just changed the oil for the first time in Wifes 2024 CX-5. Washer was painted. It was SUPER fun getting it off, but I finally did.I've also found the on my Mazda that the factory crush washer is painted on when the oil pan is painted. You must get the original washer off before putting a new one on.
You can buy the crush washers on ebay in a batch of 1000, comes out to about 3 cents each.Not everybody is Richy Rich. If it ain't leaking when I remove it, I'm putting it back on.
Too expensive.Why do you wait until it starts to leak to change the washer? Why not stay ahead of the situation and change it at every oil change?
