For E85 (85% ethanol), the effect becomes significant. E85 produces lower mileage than gasoline, and requires more frequent refueling. Actual performance may vary depending on the vehicle. Based on EPA tests for all 2006 E85 models, the average fuel economy for E85 vehicles was 25.56% lower than unleaded gasoline. [37]
By early 2013, about 11 million E85 flex-fuel cars and light trucks were in operation, [10] [11] though actual use of E85 fuel was limited, because the ethanol fueling infrastructure was limited. [46] As of 2005, 68% of American flex-fuel car owners were not aware they owned an E85 flex. [12] [13] Flex and non-flex vehicles looked the same ...
Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low-ethanol blends are typically from E5 to E25, although internationally the most common use of the term refers to the E10 blend. Blends of E10 or less are used in more than ...
Logo used in the United States for E85 fuel. E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume. In the United States, the exact ratio of fuel ethanol to hydrocarbon may vary according to ASTM 5798 that specifies the allowable ethanol content in E85 as ranging ...

The fleet of flexible-fuel vehicles in the United States is the second largest in the world after Brazil, and there were more than 21 million 85 flex-fuel vehicles registered in the country by the end of 2017. [ 1 ] Despite the growing fleet of E85 flex-fuel vehicles, actual use of ethanol fuel is limited due to the lack of E85 refueling ...
In the United States and Canada, octane ratings are in AKI, commonly shown as "(R+M)/2". All states require gas pumps to be labeled with the correct octane level and nearly all states do regular testing to make sure gas stations are in compliance. A minimum 82 octane fuel is recommended for most vehicles produced since 1984.
In Brazil, 65% of flex-fuel car owners were using ethanol fuel regularly in 2009, [25] while, the actual number of American FFVs being run on E85 is much lower; surveys conducted in the U.S. have found that 68% of American flex-fuel car owners were not aware they owned an E85 flex.
