There is no such thing as an anti-knock solution in gasoline. The anti-knock properties are acheived with the use of a slightly different refining process and a different blends of the gasoline components.
Using lower octane gasoline can (only can, not necessarily) promote some carbon deposits because of the retarded ignition but it would take a lot of mileage to be able to notice a major difference.
