BTW, I just happened to read this in the 2010-2012 manual:
BODY LUBRICATION:
LUBRICATION REQUIREMENTS:
Locks and all body pivot points, including seat tracks, door hinge pivot points and rollers, fuel door, fuel door release, parking brake mechanism, liftgate, tailgate, sliding doors and hood hinges, safety release catch should be lubricated periodically with a lithium-based grease such as Mopar Spray White Lube to ensure quiet easy operation and to protect against rust and wear. Clean surfaces of dust and dirt before lubricating, wipe up excess.
External lock cylinders should be lubricated twice per year (spring/fall). Apply a small amount of high quality lubricant such as Mopar Lock Cylinder Lubricant directly into the lock cylinder.
Later is says to use Engine Oil for door hinges, Tailgate, Hood hinges and white lube on the other points.
