 About halfway down, we stopped, spent the night, checked the oil. I had to add a quart of oil. It was a quart low. Next day, drive on to Key Largo, check the oil, quart low. So I added a quart each time. Coming home, about halfway home, we stopped, spent the night, checked the oil. It was full. Next day, drive all the way home, 500 miles or so, check the oil. It was full.
