That wasn't a point. Of course I expected some time of empty oil passages. I was shocked at how long, but maybe I've forgotten in an age where most cars don't have OP gauges on the dash.It took a while to build oil pressure because you changed the oil and filter. It's going to do that regardless if the oil is change hot, warm or cold.
The point was, if dry restarts matter at all to the engine, why not choose to the change with as much oil in/on parts as possible? (The counter argument being, why not choose to use a method that we suspect achieves the highest draining of old oil.) If we suspect overnight draining gets more of the lube to the pan, the any dry restart concerns are an argument against the method. If it's got to run without pressure for a bit, why not have some oil in/on the parts by running it briefly, cold, before the change.
I'm well familiar. I pre-filled as much as I could, but the filter goes on nearly horizontal.Any time the oil filer is removed, the galleries can drain out, regardless of the oil temperature. There is nothing you can do about that. One thing you can do is pre-fill the oil filter as much as possible. Or figure out how to crank the engine without it starting to prime the oiling system. I pre-fill the filter and fire it up, which cuts the time down to see the oil pressure. Not worried about it beyond that.
