Engine oil, also known as motor oil, is a lubricant used in internal combustion engines to reduce friction and wear between moving parts. It is a vital component for the proper functioning and longevity of an engine. Engine oils are typically made from a base oil, which can be mineral oil derived from Crude oil or synthetic oil, and they are blended with various additives to enhance their performance. The primary purpose of Engine oil is to lubricate the Metal surfaces that come into contact with each other within the engine. This includes lubricating the piston rings, cylinder walls, crankshaft, and camshaft. By creating a thin film of oil between these moving parts, engine oil helps to reduce friction and wear, preventing metal-to-metal contact that can lead to damage and engine failure.

Many modern vehicles are equipped with oil life monitoring systems. These systems use sensors and algorithms to assess the condition of the oil based on factors such as engine operating conditions, temperature, and mileage. They provide an estimate of the remaining useful life of the oil, allowing for more precise oil change intervals. This helps optimize oil usage, reduce waste, and maintain engine performance. Engine oils can be either synthetic or conventional (mineral-based). Synthetic oils are chemically engineered and offer several advantages over conventional oils. They provide better performance in extreme temperatures, have superior resistance to breakdown and sludge formation, offer improved fuel efficiency, and provide enhanced protection for high-performance engines. However, synthetic oils are typically more expensive than conventional oils.

Engine oil also serves other important functions. It helps to cool the engine by dissipating heat generated during combustion and friction. It provides a seal between the piston rings and cylinder walls, preventing combustion gases from escaping and maintaining compression. Additionally, engine oil helps to clean the engine by suspending and carrying away contaminants such as dirt, metal particles, and combustion by-products. It is important to note that different engines and operating conditions require specific types and viscosities of engine oil. Manufacturers provide recommendations for the appropriate oil to use in a particular engine, and it is essential to follow those guidelines to ensure optimal engine performance and longevity. Regular oil changes at the recommended intervals are also necessary to maintain the oil's effectiveness and prevent engine damage.

Engine oil is obtained from a combination of Petroleum Base oil plus additives and has important functions such as: lubrication (reducing friction between parts), reducing wear on engine parts, washing inside the engine and keeping the parts inside the engine clean from soot and decomposition compounds Oil and deposits between parts, complete sealing between cylinder and piston, cooling of internal engine parts, optimal operation of moving engine parts at different temperatures and protection of engine parts against corrosion and impact; All this means the lifeblood of a car!

Engine oil, which plays the role of blood in the arteries of the engine, is produced from compounds such as base oil and additives. First, Lubcat is produced in the refinery from crude oil and then it is sent to the extraction unit as the raw material of the lubrication unit to remove the materials that contain gasoline compounds, then the refined (refining materials) that contains oil to the waxing unit. It is sent to separate Paraffin and wax, and at the end it is sent to the fluoride unit to produce petroleum base oil. Used engine oil can be harmful to the environment if not properly disposed of or recycled. It contains contaminants such as heavy metals, hydrocarbons, and additives. It is important to recycle used oil through designated collection points or recycling facilities to prevent pollution of waterways and soil. Many countries and regions have regulations in place for the proper disposal and recycling of used engine oil.

Engine oil viscosity refers to its resistance to flow. It is denoted by a numerical value followed by the letter "W" (e.g., 10W-30). The "W" stands for winter, indicating the oil's performance in colder temperatures. The first number represents the oil's viscosity at low temperatures, while the second number represents its viscosity at high temperatures. Thinner oils (lower viscosity) flow more easily in cold conditions, allowing for easier engine startup, while thicker oils (higher viscosity) offer better protection at high temperatures and under heavy loads. Engine oils contain various additives to enhance their properties. These additives include detergents and dispersants that help keep the engine clean by preventing the formation of deposits and sludge. Anti-wear additives provide an extra layer of protection between metal surfaces. Anti-foaming agents prevent the formation of foam, which can reduce lubrication efficiency. Additionally, there are additives for corrosion protection, oxidation resistance, and viscosity index improvement.
