Toyota Engine Oil

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.
