I used engine flush on an old high mileage vehicle golf. The thing promptly started leaking oil from everywhere, I presume that the flush removed some deposits that were actually keeping seals ‘sealing’
With my old non-turbo engine I did pour old cheap oil in the top, ran the engine for a bit the drained it overnight with the sump plug out. No idea if it ‘flushed’ anything out or not.
When I do an oil change I give the engine a good rag beforehand and drop the oil while it’s warm (not hot - to dangerous). I leave it a good couple of hours to drain.
Then top up with new quality oil and filter.
When I rebuilt my engine, first start I unplugged the solenoid and turned it over on the key only until the oil light went out then started it properly.
