to protect it from corrosion.
A grease gun is used to force grease through a grease nipple, and so protect moving parts in a vehicle (for instance) from excessive wear.
cars are made up of mechanical moving components due to continuous moving ,there is friction between parts to reduce friction and longer life of car we need oil fro car Cars need in in order to lubricate the moving parts. In general, motor oil is the most commonly used oil in a car. This oil is meant to lubricate moving parts such as cam shafts, crank shafts, lifters and pistons. Without oil, these metal on metal contacts would heat up and eventually melt due to the friction created. Oil helps by lubricating the surfaces where moving metal parts meet. In addition, oil helps absorb and dissipate the heat generated by the friction.

Anything from within an engine, as well car doors, car windows, exterior pieces such as bumpers or tire coverings can be used as spare or repair parts for cars.
The following sites all provide parts: iapexperts, MG Cars and The MG Experience. Autotrader provides old MGB cars which could be used for spares and parts.
vegetable oil, mostly.
CNC Milling is used to make a number of machine and industrial parts. They produce parts for cars and planes as well and is now used as part of 3D printing.
Literally a device that has no moving parts. It is frequently used for electronic devices such as transistors and integrated circuits. Also a solid state hard drive has no moving parts.
Lubricating oil is used to reduce friction between moving parts and to prevent damage due to excess heat. Lubricating oil also carries away sludge preventing the erosion of moving parts.
Materials used to make cars include Aluminum, steel, fiberglass, and plastic. Each material is used for making specific parts due to their unique properties.
