I don't remember the exact test, but they check it at 500-1000 mile intervals or similar after they do an oil change, and if it uses over 1-2 quarts it is considered excessive. Their definition of excessive is a lot more than yours probably would be. I just remember that, and that they had to do the testing/checks over a period of time/miles. That is usually followed up with a compression test, and possibly engine replacement....
