Review on High Mileage Engine Treatment: Restore Your Vehicle'S Performance With Rislone 16.9 Oz! by Paul Ajayi

If your car or light truck has over 100000mi. Add a quart of Rislone instead of 1 quart of oil at next oil change. It will clean upper engine components and keep your engine going for years. I used to run this coal mine pickup trucks before I would rebuild the engines or heads. It cleaned to old engines out so well they looked almost new on the inside. Amazing carbon/sludge remover. For Real.
