Its a cartridge type. There are 3 o-rings, one goes on the plastic holder, above the thread. The other 2, smaller, go on the long 'spike' of plastic that holds the filter on. They're all different sizes so you can't get them mixed up.

The filter and filter holder unscrew together using the large plastic nut.

The filter can be stubborn to remove from its holder. Just grab it with something and pull hard.

I suggest while you're draining the engine oil, you partially remove the filter so that it drains through the engine.

The engine will take ages to drain, a good 15-20 minutes at least. Be careful if its windy, as once the flow has reduced to a trickle it will blow everywhere and make a mess.

If you don't have a new sump plug and washer, turn the copper washer around the other way when you screw it back on.

Check the plastic undertray - if it doesn't have drain holes, drill 1 or 2 into it. This helps the crossmember stop rusting.

You may find it easier to refill the engine using the oil filter holder - the opening is much larger than the filler cap on top of the cylinder head.
