If your vehicle has been maintained well, Mobil Super™ High Mileage
represents an excellent choice. However, if you believe your engine may have sludge through less-than-adequate maintenance practices, Mobil 1 High Mileage may be the more suitable selection. Mobil 1™ High Mileage
helps reduce the sludge that other oils can leave behind, which can result in extended engine life. For severe cases where sludge and other heavy deposits are present, shorter oil change intervals of 3,000 miles are recommended as cleanup proceeds.
