In 1986, my 78 Chevy Monza 2.4 I4 used about 1 qt every 3000 miles. Since then, I haven't owned a car that used any measurable amount. 1 qt every 1000 miles is a LOT to me...if you don't babysit the dipstick, you're 3 quarts down by the time you do an oil change? Unacceptable usage. Sounds like that car was broken in HARD, used oil during break-in and wasn't refilled until oil change time.
