This means that the oil can still provide a strong and consistent lubricating film, even in engines with high mileage.

Reduced Risk Of Metal-to-metal Contact

High-mileage oil also offers a reduced risk of metal-to-metal contact within the engine. As engines age, parts can wear down, causing increased friction and the potential for metal-on-metal grinding. However, high-mileage oil contains additives that help to reduce this friction and provide a smoother, more efficient operation. By reducing metal-to-metal contact, high-mileage oil can help prolong the life of the engine and prevent costly repairs.

Additives That Eliminate Deposit Buildup And Reduce Engine Wear

In addition to improving viscosity and reducing friction, high-mileage oil contains additives that target specific issues commonly found in older engines. These additives work to eliminate deposit buildup, extending the life of the engine and improving overall performance. They also help reduce engine wear by providing a protective barrier against rust and corrosion, reducing the risk of sludge formation, and minimizing general engine wear and tear.
