Engine oil additives are chemical compounds added to engine oil to enhance its properties and performance. They serve various functions, including:1. **Detergents**: Help keep engine parts clean by preventing the buildup of sludge and deposits.2. **Dispersants**: Suspend contaminants in the oil, preventing them from settling and causing wear.3. **Anti-wear agents**: Form a protective layer on metal surfaces to reduce friction and wear during operation.4. **Viscosity index improvers**: Maintain oil viscosity across a range of temperatures, ensuring effective lubrication.5. **Oxidation inhibitors**: Prevent oil degradation and extend its lifespan by slowing down the oxidation process.6. **Corrosion inhibitors**: Protect engine components from rust and corrosion.7. **Friction modifiers**: Reduce friction between moving parts, improving fuel efficiency and performance.Using the right additives can enhance engine protection, improve efficiency, and prolong the life of the oil and engine components.
