3 quarts??!! holy cow, that's insane!! i've driven a few check the gas and fill the oil rigs in my time, but they didn't owe anyone anything. 1 quart for 1000 miles is bad, but 3 quarts? maybe someone is playing with you and drained some out. you'd leave a cloud hanging in intersections and it would be no mystery at that rate unless you waited 3000 miles with your fresh motor to change the oil, but i doubt that... how many miles to 3 quarts??
