We could see gasoline prices going up again...but it's not because of rising oil prices.
Congress declined to renew the 30-year old federal subsidy for ethanol, so it expired on Sunday.
That means gasoline prices could cost four and a half cents a gallon more starting as early as this week...but exactly how much the end of the subsidy could add to gas prices, and for how long, remains to be seen.
Ethanol currently makes up 10% of most gasoline-based motor fuel for general use...so called E-10.
