Using a vacuum pump to change the oil.
Discussion
They are OK, better to use one and change 95% of the oil, than not change it at all. Some cars now are a real pain to change with under trays in the way.

You get a lot of guesswork / ill informed statements that there will be stuff left or it won't get out the bits. Prompted by someone on here doing the same thing I have actually tried extracting via dipstick (hot oil from a recently running engine cuts the time it takes dramatically) and then taking the sump plug out when it's done. About a tablespoon, maybe 1.5 tablespoons trickled out.
If there are any "bits" of any sort in the sump the oil filter will catch them in the course of normal operation. They use this exact same method to change the oil on small marine engines and they go on forever. On a car with the filter accessible from the top it makes a complete oil and filter change a 15-20 minute mess free job, providing you don't spill any on your shoes when you're emptying the used oil down the drain.

Not with that Lidl one it won't be! 0.2L/minute! That's over 20 minutes just sucking out the oil on a normal 4 cylinder engine! Although, with an electric pump you reduce the risk of mess by putting the outlet tube straight into the drain......

Yep my experience as well, plus you can suck the oil out at a higher temperature than you may be comfortable risking getting all over your hands etc If there are any "bits" of any sort in the sump the oil filter will catch them in the course of normal operation.

On my previous car I could actually get more oil out using the Pela in my driveway than I could with the sump plug.
t dripping as well. There's no complete 100% way while the engine's in and operational. Thanks. I used a hand operated pump earlier, looks a bit like a bong. Took longer to take the engine cover off than it did to change the oil and filter. We're talking 5k changes on a rattly old diesel so not risking much, and it worked really well. Just feels a bit like I'm cheating and the plug will eventually perish and fall out.
I think it depends on the car really.
If you need to get under it to unscrew the oil filter, then you may as well remove the drain plug while you're there.
If the oil filter is easily accessible, and the drain plug is hidden above a plastic sump guard, then a pump is an ideal solution.
