I don't believe so, I can't imagine why that little would have done anything at all, (especially increase gas mileage... that stuff doesn't work, BTW), but again, I can't guarantee anything.
Like I said, the worst thing it would have done (Acetone is a great solvent) is destroy a seal somewhere that might be causing a vapor leak or even a mild liquid leak. Depending on how long it takes you to burn a tank, or how long between fill ups, you might see 1 mippig difference from any of those things.
