I'm not sure about the size but the dealers sell them for less then a $1.00 and they will last for 3 or more oil changes.

You reuse them??? They are SOOO cheap I figure its worth changing them out each time. As far as I understand all subarus use the same washer... my 87 GL and my moms 96 OBS use the same washer (but different filters)

I belive I pay around 70 cents for my washers.

Crush washers should not be used twice.

On an OEM crush washer, the ID is 20mm and the OD is 26mm. The drain bolt itself is 19mm x 1.25 pitch IIRC.

ID is 27mm and OD is 30mm. For the $.75 or $1.00 these things cost, I don't know why people are going through soooooooo much trouble to find something aftermarket though... I should do a 'group buy' on drain gaskets :D!

Hehehehe...talking about replacing washer at each oil change, I've never even thought of replacing it. It didn't even cross my mind about replacing it. I've always thought I should reuse the old one until it breaks. How's that for a change? LOL

I never changed mine out either, until the recent Fumoto valve upgrade.

Never had a drop of a leak.
