Why is grease used in vehicle maintenance?

Grease is used in vehicle maintenance to reduce friction between moving parts, which helps prevent wear and tear. It provides a protective barrier against moisture and contaminants, thereby extending the lifespan of components such as bearings and joints. Additionally, grease can withstand high temperatures and pressures, making it ideal for various applications in automotive systems. Regular application of grease ensures smooth operation and enhances the overall performance of the vehicle.
