It took 4,000 miles for level to go from the high to low mark on the dipstick.
A surprise, however. It took TWO quarts of oil to fill from the low to high mark. Something I was not expecting. (All levels taken on level ground first thing in the morning before the vehicle was started.)
So the oil consumption rate is 2,000 miles per quart of oil, not 5,000 miles per quart as I thought previously.
