CASTROL 15CF7C Engine Cleaner

Modern driving creates combustion by-products that can build up in your oil. When these accumulate, they build up to form layers of sludge that can harm engine performance, especially in the latest precision engines. Castrol "Engine Shampoo" helps to maintain engine power and efficiency. By adding it to the old engine oil and running the engine for ten minutes on idle before changing the oil, sludge and dirt is then removed with the old oil when changed.
