As high mileage vehicles tend to have more wear than new engines, gaps between components can form, leading to leaks. As a car engines ages, seals and gaskets have a tendency to dry out, crack and oil begins to burn off between changes. All of this can ultimately contribute to the buildup of oil sludge and deposits in the engine, potentially shortening the life of your car's engine.
High mileage motor oils are designed to include additives that provide better lubrication, help protect engine seals, and prevent sludge from building up. This minimizes engine wear and extends the life of the engine, while ideally improving performance in the meantime.
We've chosen the best high mileage motor oils in 2022 from leading companies proven to perform over time and contain all the positive traits we've described above. Price varies quite a bit depending on oil sales at the time as well as your local market, so it's best to simply pick the oil that best suits your needs.
