Here's the way it works with the motor oil. The oil pump picks up oil from the bottom of the pan, through the pickup tube and screen, then into the pump. From there the oil goes into the crankshaft, through the crank main bearings and rod bearings. Oil is also pumped to the top of the heads to lube cam journal bearings, lash adjusters pump up, oil is dispersed along the top of the head lubricating rocker bearings and springs, etc. The timing chain tensioners and VCT system also get oil under pressure to operate. The oil also has to pass through the oil filter during this process.
Knowing all this remember...the oil drains back into the pan through the use of gravity. It follows small porous passages and makes it's way to the pan to be recirculated. Yes an engine could idle with only 2 qts in it, but I would never do that. The oil has a long way to go before it comes back to the pan and 2 qts is not enough to keep the oil pump from starving for oil especially if the engine begins to rev. You always want the oil pickup tube to be deep in oil, not pulling oil from an inch deep bath where it WILL begin to cavitate and pull air/oil mix.
Keep the oil level up!
