Check oil every fill up of gas. The cardboard idea is good to see if it leaks instead of burning it. If no leaks and you need to refill the oil, it's got to go somewhere.....(also look under the hood for crud buildup, especially around the valve cover gaskets).

If the valve stem seals are worn out or just old: sometimes blue smoke on startup, but the best test is under hard acceleration. If you get blue / black smoke, its the seals.
If the oil rings are worn out (about 180,000+ km), the engine will smoke after a about 5 minutes of idle. Good test is what happens idling in peak hour traffic. If theres a cloud od blue smoke when you finally get moving, its the rings.
If the engine has done 200,000+ you likely need both.
