I voted no because I'm wary of any fuel additives or flushes for fear of what they might do to the catalytic converters, despite any claims of the additive manufacturer to the contrary.
That's why my car will never get a Seafoam treatment or a "power wash" of the injectors, where the injector solvent gets "injected" at the fuel rail. Some may do these treatments, and they may be very successful, but IMO, our cats are too expensive to take chances with.

High mileage, low compression, and missing on a few cylinders.....just like my cars.
