Will lifting the E15 gasoline ban really save you money?

President Joe Biden is hoping to ease your pain at the pump by suspending a ban on E15 gasoline this summer.

But will it really help you save money?

DETAILS: Biden to allow higher ethanol fuel blend this summer in bid to lower gas prices

There are not a lot of gas stations in the Houston area that sell E15, but there are some.  

E15 is gasoline that is 15% ethanol and 85% gasoline. It has 5% more ethanol that the 10% you usually see at the pump.

Dr. Ramanan Krishnamoorti, a professor of Petroleum Engineering at the University of Houston, says most vehicles that run on gasoline can run on E15 without a problem.


It’s banned during summer because it causes more smog.

Ethanol is made from corn, which is subsidized, making E15 cheaper than other gasoline options at the pump.

"The claim is it's probably about 10 cents a gallon cheaper, which is about 2% to 3%. The problem with that is you also lose fuel efficiency when you put ethanol in to burn, rather than gasoline. So your miles per gallon go down when you put ethanol into your gasoline," explained Krishnamoorti.

So how many miles per gallon does it go down?

The U.S. Department of Energy finds that mileage goes down 3% to 4% on E10, and 4% to 5% on E15.

Temporarily lifting the summer E15 ban isn't new.  President Trump lifted it during the trade war with China, and it was lifted in Houston after Hurricane Harvey.
