If that's the 8.1 engine there where some issues with intake manifold gaskets losing their seal and sucking oil from the crankcase. I think there's a service bulletin regarding it. Otherwise I don't believe there's any pattern failures.

I had an '83 Cavalier (quit laughing NOW; it got 40 mpg) and once it hit 125,000 miles, it would use a quart every 150 miles at highway speeds. My buddies threatened to put up an oil derrick to reclaim the leaked oil. Nobody was able to look at it and decide where it was coming from.

If you are using one quart of oil per 1000 miles of high speed driving or if used in hot climates, this can be considered normal usage. You might also check the pcv valve and build up of oil in the valve cover (over top of the cylinder head) for blockage.

Most likely an intake manifold problem. Considering that it's an 01 and out of warranty, you could have the gasket replaced with the new FelPro gasket. It's pricey but it cures a lot of problems the OE gasket had.

I have never (and never will) owned anything but GM's but I have also never had one that didnt use oil. To use 5 quarts though thats a bit too much. You either have a oil leak somewhere or you are burning it.

I like to try the least expensive fixes first:
Check out your Exhaust Gas Recirculation (EGR) and Positive Crankcase Ventilation (PCV) valves.
Sounds like you may also have a problem with your Knock Sensor:

Bad Gas Mileage
Hesitation / Jerking
Shaking / Vibrating
Check Engine Light
Noises From Engine
Detonation / Misfiring
Strong Exhaust Smells
