That's an interesting thought, and definitely another reason why I want lead-free gas ASAP.
Unfortunately, I have no idea how to find lead- and ethanol-free gas within 100 miles. www.pure-gas.org in my area only shows places selling 5gal VP Racing fuel cans at $20/gal, Swift UL94 is only at 4 airports from Ohio to Maine, Gami 100UL is years out, etc...
