Oil Consumption
As a recent owner of a 2001 C5 with 20K miles, I'm suprised to find out it consumes a qt of oil about every 1,000 miles. Is this typical? (Stupid question probably to you old timers, but I don't know who else to ask.)

These LS1 engines are notorious for oil being sucked up through the PCV system---If you ever looked inside the manifold of one you would be shocked to see how much oil is in there--If you picked up the manifold and let it hang--oil would literally pour out of the manifold or drip heavily---Most people that have this problem do a couple things--The 2 fixes are 1) to install a LS6 pcv valley and pcv system--Cost I think was about $75 in parts--2) would be to ad an oil "catch can " on the pcv system--cost for an AMW can about $160 parts---You can do a search and several threads will come up--type in Catch can and the LS6 valley or PCV---I did both to mine --it helped alot--still a little oil in the manifold--but not bad and now I never have to add any oil in between changes--

No, it's not typical. My '00 was eating oil at the rate of one quart every 1200 miles - was diagnosed with bad #2 rings. The dealer replaced the rings under warranty back in 2001 and so far, no oil consumption since. The '01 (6 speed in particular) was known for this problem.

I would just check the oil each time you fill up.
