This Sunday, the federal ethanol tax credit expires. What this means is that it will cost suppliers 4.5 cents per gallon more for gas with 10% ethanol in it. Expect this cost increase to be directly passed on to you. This tax credit was put in place by the government as an incentive to get on board with the ethanol program. Now our country is committed to the product and the tax credit is expiring. I have never agreed with the program, but now we have it (ethanol) and I don't expect it to go anywhere.
