replace or use crush washer?

Hey guys, i will be doing my first oil change. I heard debates about replacing and reusing crush washer drain plugs. Should i replace it or reuse it?

Where can i buy the crush washers?

You can safely reuse it at least once.

You might even get a new one with your oil filter.

I buy them at the Honda dealer... He is cheaper than the auto parts stores, but they have them also.


I do reuse them 2 or 3 times.


They cost about $1 each.


or Amazon:

Replace with each oil change.

Come on guys...if you are torquing the nut to spec, the washer is being crushed..exactly what it's supposed to do.

Why cheap out?

Just replace it. They are too inexpensive to reuse.

Don't know why this is such an issue. I have never, in 55 years of riding motorcycles, replaced a "crush" washer - which don't really crush at all. In the old days they were actually hollow and would "crush" providing enough seal and tightness.

Now? They don't "crush." I put a tiny bit of RTV blue on the threads near the head and snug tighten. NEVER had a problem or leak! Hundreds of thousands of miles!

I don't even replace them on my cars (Toyota & Hondas) even when they come free with the filter.

You'll get all kind of answers to that question, hence I would refer you to the service manual it says, "After draining the oil completely, install the drain bolt with a new sealing washer. Tighten the drain bolt to the specified torque. 22 ft. lbs.

The service manual can say a lot of things that most of us will ignore. In terms of technical things, we should be listening to them. However, this crush washer thing is kind of a joke. The manufacturers also insist on our purchasing their "factory" parts. Do you follow their instructions there??

These sorts of suggestions/instructions are designed more to sell more of their products than to give advice on the best way to take care of their product.

Forget the crush washer advice - the old washer is just as good as a new one.
