I have a 2006 Grand Carvan 3.8L, was going thru about 1qt a month. Took it to a dealer and found the piston rings were not sealing. Any one else having issues with the 3.8L, only 3-4 years old seems way to soon to be going bad.
Oh thanks goodness i purchases, the Life Time Warrenty!! Oh and they replaced both slideing door motors and a few other minnor issues, only paid $100 for all repairs.
