Yes, a lot of 3.8L eat oil with no visible leaks or smoke.....Make sure you carry a couple quarts with you and chk your dip stick weekly or sooner if you drive daily.
Lots of threads about this if you do a search or just look thru the pages here. It is also noted in the Mini van forums. causes are thought to be, but not limited to....:
1) Piston rings installed up side down in Mexico (Engine plant)
2) leaking intake manifold gasket (Internal)
3) Stuck PCV valve
4) Carbon fouled piston rings
Some supposedly have "fixed" the problem by using SEA FOAM in the intake system to "De-Carbon" the piston rings . Read the instructions at Sea foam sales.com.
Some have replaced the PCV valve with a different part number ( this was later found to be only a temp. fix.)
Some have "fixed" the problem by using Synthetic motor oil..
Good luck with yours !! Check your oil and keep some on hand...
I just changed mine today, 40K miles, and I have reduced the oil consumption quite a bit by using the High Milage engine oils.... 10W-30 .. "BH"
