What is E15?

Ethanol is an advanced, homegrown biofuel that is already in 98 percent of U.S. gasoline and is moving America forward every day. And E15 – gasoline blended with 15 percent ethanol – gives drivers across the country a better, more affordable choice at the pump.

Did you know? E15:

✔ Is a higher-blend, higher-octane fuel choice
✔ Burns cleaner and cooler, which is good for your engine
✔ Utilizes more earth-friendly ethanol, which cuts carbon emissions by 43 percent and displaces chemicals that create smog and are linked to cancer and asthma

E15 for Drivers:

✔ Sold at 1,700+ locations across 30 states
✔ EPA-approved for cars 2001 or newer
✔ Warrantied by automakers for 93 percent of new vehicles
✔ Saves up to 10 cents per gallon compared to traditional fuel
✔ Eight billion miles driven on E15 by American motorists

E15 for Our Communities:

✔ An opportunity to reverse a 44 percent plunge in farm income over the last six years
✔ Boost employment by 136,000 jobs, on top of nearly 366,000 jobs nationwide supported by ethanol today
✔ Create a market for up to seven billion additional gallons of U.S. ethanol and two billion bushels of American corn
✔ Support rural manufacturing at more than 200 biofuel plants across the heartland

Restrictions are Holding Back Consumer Choice

Unfortunately, an outdated regulation known as Reid Vapor Pressure – or RVP – is preventing drivers from accessing cleaner, more affordable biofuel blends and cutting homegrown biofuels out of a key market.

RVP is the measure of how quickly fuel evaporates. Due to an antiquated regulation, the federal government holds 15-percent ethanol blends (E15) to tougher standards than traditional gasoline (E10) during the summer months. However, EPA data shows that E15 results in lower evaporative emissions than traditional blends.

With a simple fix – allowing the sale of E15 year-round – we can give drivers better fuel choices for their wallets and the air we all breathe.

The Path to Year-Round E15

In October 2018, the administration directed the Environmental Protection Agency (EPA) to lift summertime restrictions on the sale of E15, proclaiming “we are unleashing the power of E15 to fuel our country all year long.” In response, the administrator of the EPA, Andrew Wheeler, has pledged to ensure the new rules are in place before the start of the summer driving season on June 1.

Leaders from across the Midwest and beyond have rallied behind the push and are urging the EPA to ensure that nothing stands between American motorists and better options at the fuel pump.

How did we get here?

In 1990, Congress limited the amount of evaporative emissions from vehicle fuel as measured by RVP. To meet the summer RVP requirement, Congress specified that 10 percent ethanol fuel blends (E10) would receive a one pound per square inch (psi) RVP waiver because ethanol-blended fuels reduce tailpipe emissions.

However, E15 was not yet on the market when these regulations were implemented, and equal treatment was never extended to higher ethanol blends. Nevertheless, the EPA has long recognized that “E15 is likely to result in somewhat lower evaporative emissions compared to fuel currently sold in much of the country (E10) as a result of the lower volatility of E15.”

The EPA is not alone. Environmental experts agree that E15 reduces airborne pollutants. In fact, independent research suggests that ethanol blends reduce toxic emissions byup to 50 percent, including smog and ultra-fine particulates.

Yet these outdated regulations remain in place, barring many retailers from offering E15 to all drivers during the summer driving months (June 1 to September 15).
