Interesting mod to the sump on a 1.6 here

I've also read some people will push the recessed hole outwards from inside. Anyone modded theres ?

Found this sump which looks like the drain hole is not recessed inwards, anyone tried it ?

I've emailed the seller to see if the drain hole is exactly like the one pictured on the ad (ie not recessed)

I've seen these pumps for about 20/25 Euro in Lidl and one day I'll buy one!
Might be a an option for getting more of the old oil out without the trouble of changing the sump. https://www.youtube.com/watch?v=PeqhlXbsM7Y
You never get all of the old oil out at a change as it sits in galleries & pockets - and there's the risk of disturbing muck if you use a flushing oil. If your car has had regular services then all will be well and, with the simplicity of using a pump, you can halve the oil change intervals and only change the filters at the full service mileage.

Interesting,
I wonder if it would pick up much remaining oil say after the oil has first been drained from the sump hole.
Hate to run a battery flat though.

It only runs for a couple of minutes, so no battery issues. In France there are self service oil change points near supermarkets where you put a tube into the dipstick hole and pay a few Euro and it sucks the old oil out and disposes of it. In some ways it would be better to add a piece of metal brake pipe tubing to the flexi so that it hits the bottom of the sump and pulls out as much as possible, but that said the flexi is likely to lay flat and only a mm or two of oil will be left, even less if you park the vehicle on a slope to get the remaining puddle under the dipstick hole.
The end of my dipstick is in the sump somewhere, after the plastic bit that shows how much oil is there fell off - typical Citroen - they appear to become more and more reliable as time goes on as most of the dodgy bits have fallen off during the first few years.
I guess a way to check the efficiency is to put a piece of wire into the sump through the dipstick hole and see what depth is left after normal sump draining via the plug, and then see if you can get any more out with the pump.

   I've modified my sump by pushing the recess outwards.

I don't own a hydraulic power pack but do have an oxy - acetylene set which I used to heat the metal to red and then with the sump plug still in place tapped it outwards with a suitably big socket mounted on a long extension bar, simples.

I reckon it could be done cold with a bit of thought and good support underneath.

I've used a Lidl pump for a couple of years now, and I'm convinced that it removes more oil than can be drained through the sump plug, because of that recess. You can manoeuvre the pipe when it's in the sump to make sure you leave the minimum residue of oil. Also handy for sucking out the remaining oil in the filter mount and cover. It makes the whole job a lot cleaner, quicker and easier, well worth the £12 the pump cost.

Have you measured the amount of oil removed or tried removing the sump plug to see if any oil drains out?

To be honest, I was going to just out of interest but I don't think it's worth the hassle as there is no logical reason there would be anything above the level of the recess. When you pass the pipe down the dipstick hole you can feel it hit the bottom of the sump, so it's doing a pretty good clear-out.

In these 1.6 HDI you will be getting more oil out by suction,I have both an electric pump and a manual one much prefer the manual one.
