The purpose of car grease and fluids is to provide lubrication and reduce friction between parts. Without being properly greased, parts are likely to become damaged or worn more quickly which could cause a lot of unnecessary damage to the vehicle. The grease and fluids used for cars can come in a variety of different forms, but they will usually have a high melting point, allowing them to work even when a car becomes hot.
