In a Fact Sheet released by the White House last month, the administration stated that the EPA would be taking steps to temporarily allow the use of the E15, an Ethanol Gasoline mixture. 

The EPA is set to issue a voucher enabling the sale of the fuel during the 2022 summer driving season. 

The E15 blend can cost 10 cents per gallon less on average. The hope is to ease the national average gas price, which currently sits at $4.87 per gallon. 

The White House said the choice of allowing the sale of E15 was the "latest step in expanding Americans' access to affordable fuel supply and bringing relief to Americans suffering from Putin's Price Hike at the pump."

Under President Trump, the EPA granted E15 a waiver for year-round use in 2019. However, the U.S. Court of Appeals for the District of Columbia Circuit struck down the rule last year. The decision was centered on the reality that the E15 fuel contributed to pollution and was a contradiction to Biden's climate change initiatives.

The more immediate concern facing consumers will not be the potential for a small amount of increase or decrease in pollution levels as a result of E15. The problem for most will be the thousands of potential dollars in additional expenses necessary as a byproduct of using the fuel. 

According to the U.S. Energy Information Administration (EIA), pure gasoline will give drivers the most miles per gallon. Using E15 reduces miles-per-gallon by about 4-5%. This means the driver will need to fill up more often and draw more need for fossil fuels in the long term. 

The most significant concern for most consumers will be the cost or wear and tear to their vehicle, even the potential of the car completely failing due to the use of E15.
