Yeah, but that is a fuel system additive/cleaner and not an engine cleaner like what Xenderx is looking for. If you use a high quality gas with detergents, you really dont need the fuel system cleaner and if you change your oil regularily with good quality oil, you really don't need to use an additional engine cleaner, IMO. I just personally tried the Liqui Moly motor clean for the heck of it.
