What's the difference between AR6500 Diesel Treatment and AR6400-D Diesel Fuel System Cleaner?

AR6400-D is a one-tank treatment that rapidly deep cleans the entire fuel system. AR6500 is a on-going maintainance treatment that improves fuel quality at every fill-up. For best results, use both with the Diesel Fuel System Kit.
