Oil Pan Drain - Crush Washer

Hello all,

I’ve been considering getting a pump to suck the oil out the dip stick but haven’t pulled the trigger yet. Guess I’m just a little old fashion and I don’t mind getting under the car and letting it drain.

My question is, I did my first oil change as owner on this thing about 10k miles ago and when I did it, I re-used the crush washer for the drain plug. Needless to say, I had some decent oil leakage after that change. A buddy of mine who is an Audi tech told me that you should always replace the crush washer. Well, it’s about time to do my next change and I was just wondering.

Now, on other cars I’ve owned, including an A4, I’ve always re-used the crush washers with no issue.
I mean, I do understand that that is the specific purpose of a crush washer so the new washer is ‘crushed’ when tightened but like I said, never had an issue with any other vehicle.

If the new filters came with crush washers I wouldn’t even ask but since I would need to buy a single washer every oil change that’s why I’m asking.

Do y’all re-use the washer or get new ones? (for the people that still do their oil change the old fashioned way)

Is there an Audi part number (Hopefully not like a $20 washer) for this washer or can I just get some generic crush washers from amazon and throw one on every change or something?

Also thought about a quick valve purchase that I would never need to remove from the pan but am hesitant on it for the simple fact I don’t want anything sticking out, even a little bit, from the pan.

Any info is appreciated.

Thanks!

When I did my oil change about a month ago, I did not change the washer. I just re-used the old one. When I first tightened it, there was a slight drip. But I then torqued the plug to the proper torque and it was sealed.

That said, next time I change the oil, I will also change the washer. It is what you are supposed to do.

Here is a link to amazon for the proper washer. It is a pack of 10 for $10. https://www.amazon.com/gp/product/B07GJYJN96/ref=ox_sc_saved_title_4?smid=A2LO3L8XS4ABB4&psc=1

Thanks for that link, not bad at all. Do you happen to have that torque spec handy or remember what it was for the plug?

for cars with topside oil filters, i love using my vacuum container to suck the oil out.
Takes a long ass time, but i clean the shop while doing it. I use the big green one from harbor freight as the mighty vac ones are too small to hold 10q. Vaccum it down, stick it on down there, undo the filter, have a beer. No mess, no fuss, no effort.
