There are only two ways for it to be getting away. Either out the tailpipe from a blown head gasket or cracked head or block, or it could be leaking out when the car gets hot and then the passage out seals back up when it cools down.

If it is the first that is somewhat expensive problem. In that case you should see some steam coming out the exhaust and be able to smell a sweet smell from the exhaust. Steam vs smoke will dissapate into thin air shortly after exiting the exhaust pipe.

If it is losing coolant you should be able to find some leaking out somewhere when you park the car after driving it and getting it good and hot.

Good luck
