i have to add a quart of oil about every 1500 miles
how do i correct excessive oil consumption in my 3.5 v6 chrysler on 2006 Chrysler 300
check pcv valve its worth a shot but its probly a top or bottom rebuild
try oil stabilizer to oil supply. this will recondition seals and cylinders. result will take drive time. i think toolbx may be right about rebuild though. remedy may buy u time.
