I'd like to get more of the old oil out when making a change.
All of the old, extra oil has to come out eventually.... Let it drain for 4-5 days or longer, however long it takes to get all 5.7 quarts out.
May be but it is dependent on the sump design, plug position, car ramp height etc. It will work better on some cars than others.I know how I do it on an old car or motorcycle. Just pull the plugs or disconnect the ignition system then crank the engine on the starter for a few seconds. Must be much more complicated to prevent a modern engine firing up when cranked so I've never tried it.
For what it's worth I find using an oil extractor gets more oil out than using the drain plug. That doesn't make sense but I've measured it and found that to be the case.
I remember back in the 1980's doing an oil change, now I do take the oil dipstick out as well as the oil cap and PCV hose before doing an oil change. Does more oil come out, who knows, but it seems to pour out better, LOL
Anyways, I was changing my oil 1 day and my buddy gave me a quart of Mobil 1 15W-50, he told me after my oil drained out I should pour it in and it would flush out the old oil. It did not work out that way, what came out was fresh oil. The old oil, guessing half a quart or more was somewhere else.
You clearly don't understand the question. I reread what I wrote in case I wasn't clear, but it seems clear to me.I drive the left side of my Canyon up on a 2x4 so the pan will drain toward the plug, and I've been known to let it drain overnight. That's about as much as you can do....let gravity and time assist as much as possible.
