High-mileage oil contains specialized ingredients designed to address the unique needs of older engines, helping to extend their life and improve performance.
Based on expert information, high-mileage oils typically include a blend of specific additives not always found in standard oils. These are formulated to combat common issues in engines with many miles on them.
Here are the key components often found in high-mileage engine oil:
- Conditioners: These work to restore and maintain the flexibility of engine seals and components that can become brittle over time.
- Seal Swells: Designed to gently swell aged seals, helping to prevent or reduce leaks that are common in older engines.
- Antioxidants: These additives help prevent the oil from breaking down due to oxidation, which occurs over time and high temperatures, keeping the oil effective longer.
- Detergents: Similar to detergents in regular oil, these help clean engine components by preventing sludge and deposit formation, which is crucial for maintaining efficiency in older engines.
- Wear or Friction Additives: These form a protective layer on metal surfaces, reducing friction and wear between moving engine parts, which is vital for the longevity of high-mileage engines.
Furthermore, these oils typically utilize a viscosity modifier that is particularly durable. This type of modifier is resistant to breaking down and losing its effectiveness, which helps the oil maintain its required thickness. Staying thicker longer is essential for providing adequate lubrication and protection to the worn parts of a high-mileage engine.
In summary, high-mileage oil is more than just conventional oil; it's engineered with a specific additive package and a robust viscosity modifier to cater to the demands of well-used engines.
