Actually gas distributors stopped shipping 87-unleaded gasoline to Iowa recently. The only alchy free gas you can buy now is premium grade that costs about 50 cents per gallon more than the alchy blends. Buy premium for your small gasoline engines like chainsaws, snowblowers and generators and such.
The alchy gas blends are curtsey the corn lobby. Blending gas with corn-alchy is incredibly stoopid thermodynamics. Thank big fat subsidized corn farmers and big green farm implement industry. Is extremely sad for the soil the way they farm it now for all the corn and beans going to distillers. The pictures now of bad commodity farming are worth a thousand words about their soil erosion.
