I actually did this once; but I had ulterior motives! I forgot to replace the oil drain plug because I was being so ultra careful. And I didn't have any scratch for another quart... Sheesh. Once bitten twice shy, as they say.
Anyone Else "Oil Flush" When Doing an OC?

My late father-in-law was big on waiting until nothing, and I mean nothing, was coming out the drain plug.
Wife tells a funny story about the first time she took her car to an oil change place after she moved out and was living on her own.
She took a book to read because in her mind it took two hours to change the oil, she never knew any different.
She goes into the waiting room, gets about three pages into the book, and they tell her that her car is done.
"Huh? What?" How can that be?"

In the case of an extremely slugged engine I might consider filling it all the way to the top of the valve cover with the solvent and letting it soak a day, then draining. Unless the problem is that extreme I’m happy to just drain the old oil and replace it.

I flush my lightly abused used oil every 3k. Even top dollar Amsoil and soon to be HPL.Not sure of exactly how to phrase the title, so gave it my best shot!
I have watched some Lake Speed Jr. videos recently and in one video he is changing the oil in his daughter's new Toyota. What surprised me is he did a step in the OC I have never thought about doing.

Since 1970 I've operated this way. Goes with the territory of being first & last owner and if necessary, removing the top of the engines at old age and seeing utmost clean engines.
Please don't attempt to teach this old dog new ways. Don't bother to tell me I waste money. I don't smoke, drink, waste money at fast foods, buy subscriptions / memberships / sports team tickets, jewelry......etc.
I could go on & on & on.

That was my take - it was bcs of break in metals … Not a regular practice.
I don't even flush every time I take a dump, much less change my oil.

I do this too with my Subaru Ascent but only because it takes 4.7 quarts so I always have some leftover 0w-20 I have no use for and figure it gets some use out of it and empties the jug I need to return used oil. Outside of that situation it's probably a waste but if ppl want to that's cool
OCD & a Waste of good oil.
I inadvertently did what LSJ did, with 6-quarts, once…because I forgot to put the drain plug back in. Caught my error after pouring 6-quarts in when I checked the dipstick and found it was dry. Oops.
I have only used the @High Performance Lubricants Engine Cleaner 30, once the Valvoline Cleaner at Walmart, and occasionally 125mL of Gumout Multitune same day before oil change.
