My car needs a quart about every 1500-2000 sometimes even a little less than 1500...the dealer told me it was considered normal for Fords standards They also told me the a quart every 1000 miles was still within spec Running Mobil1 has been very expensive for me but I still run it in all my cars and change the oil about every 3500-4500 miles.
