Engine oil additives are chemical compounds added to base oil to improve its performance and protect the engine. They perform crucial functions such as reducing wear, preventing corrosion and sludge, and keeping the engine clean by suspending impurities and forming a protective layer on metal surfaces. Additives also help modify the oil’s viscosity to ensure proper lubrication across different temperatures and prevent foaming.
Key Functions Of Engine Oil Additives:
Reduce wear and tear: Anti-wear additives create a protective film on metal surfaces, minimizing friction between moving parts, especially during startup.
Keep the engine clean: Detergents remove deposits, while dispersants keep impurities suspended in the oil, preventing them from forming sludge and getting circulated to the oil filter.
Protect against corrosion: Corrosion inhibitors form a barrier on metal parts to protect them from rust caused by water and acids in the engine.
Control viscosity: Viscosity index modifiers ensure the oil remains fluid and provides proper lubrication, whether the engine is cold or hot.
Prevent foaming: Antifoam additives stop air bubbles from forming, which could disrupt the oil’s ability to lubricate effectively.
Extend oil life: Oxidation inhibitors slow the degradation of the oil, extending its useful life.
Maintain seals: Seal conditioners help keep engine seals pliable, preventing oil leaks.
