Draining oil too well is bad

To you, maybe. You obviously don't have an oil and/or filter shrine.
Aren't there check valves in some oil pumps that prevent it from loosing prime?
I did a timing belt on an engine with hydraulic lifters. Clanked like a MFer when I started it up. Thought I destroyed the engine. But as soon as oil pressure built up, it went away.

Well for what it is worth, I now let oil drip for a couple of hours, even more in summer, while I never put any oil into new filters. On Hondas and a Mazda I never heard any sort of unusual noise.
I change the filter, drain the oil for 5 minutes or I get impatient (whichever is shorter), put the plug back in, fill it up, and call it done.
You people who bounce the front end up and down, let it drain for hours on end, turn the engine over without oil in it, etc. really exemplify the phrase "diminishing returns".

What have you started JAG?
I get very little out of the filter after I unscrew it (it hangs nearly straight up and down), just whatever spill out of the filter. I pop the drain bolt out of the pan, catch a smoke, change the filter, put the bolt back. There's a little still coming out, but such a thin stream, if there was the slightest breeze under the car, it would blow away. At that point, what's left in there? 1/2 pint? 1/4?
Some things, you have to just...let go of.

Cranking the engine without oil?
That sounds wrong on so many different levels.
I like to crank with the "clear flood" thing for 1-2 secs. before starting for real after an oil change. The only way for me to fill the upside down mounted oil filter. Without doing this, I get to see the oil light stay on and hear my valves clacking for a couple seconds instead. Necessary? probably not but its easy enough to do.
As far as draining every last drop, beyond 10 or 15 min. no more is gonna come out.

Wrong on three counts:
1. The oil filter must be pre-filled.
2. The oil filter gasket must be coated with fresh oil
3. While the drain plug is out and after the new oil filter has been installed and with dipstick in, a dollop of fresh oil must be poured into the oil fill. Some will explain this as a "mini oil flush", but in reality, it is a sacrifice to the oil gods.
Many posters here need flushing much worse than their engines,,,,the engines are only full of oil.

Or....remove the engine, invert it over a drain pan, flush out all the old oil, reinstal the engine after manually primimg the engine on the bench with.........you get the idea!
Thats what I do every 3000 miles
