Since about 93k miles when I first found out about the oil issues following an oil change when I saw barely 1 qt come out, I have been religious in tracking the oil consumption. If you are worried you may not fail the test and get the Toyota fix, make sure you do NOT bring it to them following a recent oil change. I noticed that the engine burns a lot more oil as the oil ages. Aka burns less oil immediately following an oil change vs if you put a few 1000 miles on it. My 2 cents.
