    That's a good tip, thank you.

    Finally did another oil change, I know should have done it sooner. 13,000km or 8,000mi over 3 years.

    Indeed the previous washer was present, the second washer also stuck on there. This time I'm 100% sure because I put one there last time.

    Using an open ended wrench did the trick, sort of pry from the centre.

    Used an oil extractor this time, the manual version, it was quick and easy even without an air compressor.

    It was able to extract 3L of oil through the dip stick tube. Probably can do more if the front wheels weren't on ramps. No oil came out from the drain hole, so it is not less effective than draining.

    Such a blessing for cars with top mounted oil filters, still great help for Prius.

    Did what trick, breaking loosen the old washer? I find a slim, flat-bladed screw driver blade, tapped in with a hammer, jars it loose. Typically do that as soon as the drain bolt is backed out a few turns, less messy.

    removing drain bolt and using an oil extractor seems a little belts-and-braces. Still, interesting experiment, seeing how thorough it was. If anything having the front raised should improve drain, due to drain bolt being at trailing edge of oil pan.

    myself, I’ve made it this far just removing drain bolts on cars, so I’ll stick with that. I can see it being very handy though, say for partially extraction, due to overfill.

    Anyone got any tips on where to buy a bunch of oil plug washers for Gen2 and Gen3?

    Our dealership used to charge about $2 CDN per. Last time they just threw it in without mention, change in policy I guess. Their Mazda dealership (right next door) has adopted the same policy. The two locations are handy; I typically park at the Mazda dealership (better odds of finding a spot), pick up oil filter for son's Mazda, then 'round the corner to Toyota for our Prius. Oh, and next to the Toyota place, Lexus, all under the same umbrella.

    You're looking for Part # 90430-12031
    Toyota MSRP is $1.64 as of today - Gasket #9043012031 | Autoparts.toyota.com
    So that's like $16.40 for 10 gaskets.

    If you do an internet search for "Toyota 90430-12031", you'll get a bunch of hits on 10-packs for slightly cheaper (maybe $10-ish). Those items' pics show the plastic bags with official looking Toyota logos (which look like the bag that I purchased when I bought a bunch during a Toyota sale).
    If you don't care about using genuine Toyota parts, I'm sure you can opt for the much cheaper generic stuff that pops up in the search.

    I got one of those aftermarket packs one time, they had shards on the edges, looked rough. I returned them, not worth the suspense.
