Change engine oil and flush with more oil, useful or useless?

[Mala23]

Hi everyone, I plan to change the engine oil myself, so I looked for more information and videos on the subject to do it in the best way. The idea was to try to clean the engine a bit from debris (I bought the van that already had 200k km) but I don't trust using additives like flush, because I'm afraid of possible damage. I saw the video that I'll link below where the guy who does the oil change suggests doing one or more washes with half oil to clean the engine, but this also scares me a bit, so I ask you experts for an opinion, could it be useful? Or do you have your own method? Or do you consider it useless? Many say that changing the color of the oil from clear to black is not a problem, but I would still like to be able to do it well, even if it wastes a bit of oil and money. Thank you very much for your advice.

Flushing the engine with clean oil is an added expense and leaves you with more oil to dispose of. I'm not convinced that it serves a purpose.
I get the engine up to operating temp then drop the oil through the sump plug, remove the old oil filter and leave it to drain for at least 15 minutes before replacing sump plug and new filter and refilling with oil. I do mine every 8 - 10K miles, frequent servicing is more important than engine flushing, IMO.

Provided the van has previously been serviced on schedule and with the correct lube there is nothing to be gained by not doing a straight sump-dump, changing the filter, refilling, and getting on with life.
