I too have done it, though the name of the product momentarily escapes me.

Edit: Just found the bottle in my garage. It's called Star Tron - Enzyme Fuel Treatment. On their website they say:

"Ethanol / E10 fuels increase the amounts of water and sludge in your fuel tank. Star Tron breaks down this excess water and sludge to sub-micron size allowing it to be safely burned away during normal engine operation. Therefore Star Tron prevents phase separation and fuel gelling, eliminating ethanol fuel problems."

Apparently it also helps increase mpgs, though I've never measured the before and after effect. It did decrease engine stuttering and hesitation, though, and made for more linear and predictable power delivery.

I was talking about the race fuel, not ethanol additive.
