What year did they mandate ethanol?
2005
Congress enacted the ethanol mandates (RFS) in 2005 and then aggressively expanded them in 2007 with the hopes that turning corn into fuel, in place of regular gasoline, would expand the nation’s renewable fuels sector, help the environment, and reduce reliance on imported oil.
Will 15 ethanol hurt my car?
One of the major complaints by E15 opponents is that ethanol can corrode many of the plastics, metals, and rubber components used in internal-combustion engines and their fuel systems. Hence, using fuel with a higher concentration of ethanol than the manufacturer recommends may damage your vehicle.
When did they put 10% ethanol in gas?
Gasoline containing up to 10% ethanol began a decades-long growth in the United States in the late 1970s.
What time of year is ethanol added to gasoline?
Today, the EPA acted on a proposed change to expand the amount of ethanol that can be mixed into pump gasoline from June 1 to September 1. In an official announcement, the agency made no comment about how the move might affect summer air quality or pollution issues.
Does higher octane have less ethanol?
In terms of its octane rating, ethanol has a rating of 113. As mentioned above, fuels with a higher octane rating reduce engine knocking and perform better. So the higher the ethanol content, the higher the octane. The octane rating for E15 (15% ethanol) is 88 octane and E85 (85% ethanol) is 108 octane.
Is ethanol still used?
In 2007, the RFS renewable fuel use targets were set to rise steadily to a level of 36 billion gallons by 2022. In 2020, about 12.6 billion gallons of fuel ethanol were consumed in the United States. Most motor gasoline now sold in the United States is about 10% fuel ethanol by volume.
How much ethanol can I put in my car?
Most cars today can run on ethanol gas blends up to E15 (15% ethanol) and on non-ethanol gasoline. And flex fuel vehicles can handle up to E85 (85% ethanol) without a problem.
Does 93 octane gas have less ethanol?
Don’t be misled into thinking higher octane gas contains less ethanol. In fact, it has more! The octane rating of pure ethanol is 100, but when it’s blended with gasoline, it performs as if it’s 112. In other words, higher-octane blends — Petro Canada’s 94 and Esso’s 93 — use more ethanol, not less.
When did Florida stop requiring ethanol blends in gasoline?
These states, particularly Minnesota, had more ethanol usage, and according to a source at Washington University, these states accumulated substantial environmental and economic benefits as a result. Florida required ethanol blends as of the end of 2010, but has since repealed it.
Where does ethanol have to be blended with gasoline?

Which is the first US city to require ethanol in gasoline?
In 2007, Portland, Oregon, became the first U.S. city to require all gasoline sold within city limits to contain at least 10% ethanol. Chicago has proposed the idea of mandating E15 in the city limits, while some area gas stations have already begun offering it.
