1. Reduced Oil Consumption: High-mileage oils often contain additives that help reduce oil consumption. As older engines tend to burn more oil, using an oil that minimizes this issue can be beneficial.
2. Enhanced Viscosity: High-mileage oils may have a slightly higher viscosity than regular oils. This helps to maintain proper oil pressure and protects against leaks in older engines with looser tolerances.
3. Deposit Control: High-mileage oils often include detergents and dispersants that help prevent and remove sludge, varnish, and other deposits that can accumulate in older engines.
4. Anti-wear Additives: These oils contain additives that provide extra protection against wear and tear, which can be significant in older engines with high mileage.
5. Improved Sealing: Some high-mileage oils may contain additives that help revitalize seals and gaskets, reducing the chances of leaks in older engines where seals might be worn.
6. Oxidation Stability: High-mileage oils are designed to resist oxidation and breakdown over time, which is crucial for older engines that may experience extended oil change intervals.
7. Compatibility: High-mileage oils are formulated to be compatible with older engine materials, ensuring they don't cause any damage or harm.
Always refer to the vehicle's owner manual or consult with a qualified mechanic to determine the specific oil type and grade that is recommended for your older car. They can assess the condition of the engine and recommend the most suitable oil based on factors such as mileage, climate, and driving conditions.
