You want to use this oil because you need the special seal conditioners and detergents for a cleaner running engine and added protection. You need this right? If you don't use high mileage oil; you run the risk of having your seals dry out, losing there sealing qualities and attributes. You dont want that happening do you?
Oh and by the way, if you're thinking of using a blend or full synthetic, you must not because you have over 75,000 miles on miles on your car.
