Went to Murphy's for 12 gallons of ethanol-free

If it's carbureted, why use Ethanol free? The Get-out-jail-free card for most e-tests is ethanol-rich fuel, at least for the test. You barely passed on CO, which is typically lowered by ethanol (or more oxygen/better working AIR pump). Just wondered.

Because I don't think that ethanol is good for the rubber parts in my fuel system. So I wanted to see if I could pass without it.
