Results in on Five Samples of High Mileage

High Mileage Motor Oil

High Mileage motor oils are typically formulated for use in vehicles with more than 75,000 miles. They contain additives that help reduce oil leaks and burn off by swelling o-rings and gaskets. In addition, some include additional detergent/dispersant or other additives to remove sludge from engines or provide other improved wear or oxidation performance. As with other motor oils, high mileage oils can be conventional, synthetic blends, and synthetic with corresponding use of different base oil types.
