I'm told to not to break the seals even if it results in the engine blowing up. This raises a moral and ethical problem in that they are putting their test above our safety. Next week I'll be driving to a very rural area of Arkansas with Anna. Just suppose the oil light comes on, and I have to choose between stranding us, leaving Anna alone, and walking off to find help or getting the quart of oil out of the trunk and continuing the drive. While this is a very, very unlikely event, I will put that quart of oil in the engine. For that matter, I wouldn't willingly strand us on the interstate.
If it burned a quart in the first 4,000 miles or so, you should be very safe on your 1,200 mile trip. If you drive a lot of miles before you start your trip, you can have the dealer check the oil and reseal the dipstick.
Unfortunately, that is the way oil consumption tests work because otherwise (surprise!) owners will drain or extract oil in an effort to show excessive consumption and get a new engine.
Ultimately though, I think this exercise will not be useful. Toyota and other manufacturers all consider a quart/4,000 miles very acceptable; most will do nothing unless it gets to the quart/1,000 mile range. And cars do tend to use more oil during break-in, so this may very well improve. Even if it doesn't get better, a quart per 4,000 miles is hardly a major problem - just keep an eye on it and top-off as needed. As long as you do this, there's absolutely no reliability issue.
