Car oil, also known as motor oil, is a crucial lubricant used in internal combustion engines. It helps reduce friction between moving parts, ensuring smooth operation and preventing wear and tear. Car oil also plays a vital role in cooling the engine by dissipating heat, cleaning contaminants, and protecting against rust and corrosion. Available in various types, including conventional, synthetic, and blended oils, each has its own benefits depending on the vehicle's requirements and driving conditions. Regular oil changes are essential for maintaining engine performance and longevity.

Car coolant, also known as antifreeze, is a vital fluid that helps regulate the engine's temperature. It prevents the engine from overheating by absorbing excess heat and transferring it to the radiator, where it is cooled down. Additionally, coolant protects against freezing in low temperatures and prevents corrosion within the cooling system. Typically composed of a mixture of water and ethylene glycol or propylene glycol, car coolant comes in various formulations designed for different vehicle types. Regularly checking and replacing coolant is essential for optimal engine performance and longevity.
