Always refer to your vehicle’s manufacturer recommendations or consult a trusted mechanic to determine the optimal viscosity for your specific application and climate. These conditioners are designed to condition and restore the elastomeric materials used in valve cover gaskets and other seals, making them less brittle and more watertight.
How High Mileage Motor Oil Engine Longevity Works
Beyond the preventative protection, these oils are formulated to clean out accumulated sludge and varnish that can build up over years of service. High-mileage motor oil incorporates seal conditioners that swell these older, slightly degraded seals, restoring their flexibility and preventing oil leaks.
High-mileage motor oil is specifically engineered for vehicles that have accumulated significant distance, typically 75,000 miles or more. The detergents in these oils are more aggressive, designed to keep old engines running cleaner and quieter by suspending contaminants until they can be trapped by the oil filter.
