Slippery question

With water-cooled cars, the amount of cooling fluid is limited to have it heating up quicker, and once the thermostat opens, the fluid is allowed to flow through the entire system including the radiator.
Just wondering how this works for an oil-cooled engine.

All the oil in the oil tank (dry sump) is used for lubrication and cooling (piston squiters). The engine on startup instantly starts to scavage the oil out of the block. The scavaged oil goes to the oil tank. Basically you have the full capacity of the system right at startup, minus the oil capacity that is in the oil lines that go to the oil cooler, and oil cooler.

You have about 8 litres available in the engine very shortly after it starts to turn and then fire. Once the oil cooler is opened a huge amount of heat is released and quickly especially if moving forward,
