Aside from some possible damage to the cat and maybe some damage to rubber seals in the fuel system, the 111 Octane will not give you any benefit. It does not burn cleaner, it does not have less or more contaminants in it. It is a pure waste. And I'd be afraid that this stuff might be contaminated, not knowing how/when/in what condition is has been transfert to a pail.
Too much of a good thing is nor necessarily better.
Think about washing your tires with surgical grade distilled water.
Would you see any benefit?
