With a dry sump setup oil can drain down when the engine's not running.
As soon as you start it up the oil's pumped back up into the tank.
That's why you need to check the oil level straight after the engine's been run - or even for some cars whilst it's still running.
Triceratops, that is why it is so important to check the level with a running engine after your filling up. Eventually you filled up too much and then you will have a problem when cruising with oil blowing out, be careful
