Ok, what’s that expression about “fools rushing in where even the brave won’t go” ? …lol … I’m not sure of OP’s motive for posting their proposed method, since I don’t recall that particular puzzler; but I can think of a practical motive where you might want to do that. There was a discussion in these parts fairly recently about what to do when the oil drain plug leaks after you change the oil. Tighten it, or replace the plug? If you decide to do what’s probably the correct method, replace the plug, you’d prefer to not have to drain all the oil out, and not dump the whole 6 quarts on your head in the process or replacing the drain plug. So something like this might work out ok for that.
Me, as a diyer, I wouldn’t do it that way. I’d worry that the oil would damage my vacuum cleaner, or worse. I’d either risk oil on me by just doing it fast, or drain the oil out into a clean pan, then pouring it back in later.
