Every 3000 miles of driving or every three months, the door, hinges, and latch assembly as well as the doors, the
Hood, and the trunks should be lubricated with few drops of light oil or lock lubrication. Also, the door latch strikers require a thin layer of grease on them to reduce mechanical friction hence preventing rapid wearing out. Other areas that should be lubricated include the door and trunk locks that should be lubes using the spray on graphite lubricant.
