What's the difference between E10, E15, and E85 gas? From the U.S. Energy Information Administration https://www.eia.gov/tools/faqs/faq.php?id=27&t=10 and Popular Mechanic https://www.popularmechanics.com/cars/car-technology/a25135/guide-to-fuel/
All gasoline engine vehicles can use E10. Currently, only flex-fuel and light-duty vehicles with a model year of 2001 or newer are approved by the EPA to use E15. Flex-fuel vehicles can use any ethanol-gasoline blends up to E85.
• Ethanol helps the fuel meet federal air-pollution regulations. It reduces tailpipe emissions of carbon monoxide, hydrocarbons, benzene, and fine particulates.
• Ethanol contributes to fulfilling the national energy independence goals presented in the 2005 Energy Policy Act and extended under the Energy Independence and Security Act of 2007.
• Ethanol is a powerful octane booster—a fuel additive that prevents the fuel charge from preigniting in the cylinder, which leads to engine knocking and poor performance.
• With 33 percent less energy content than gasoline, ethanol actually lowers your gas mileage.
• Ethanol is known to ruin small engines, especially two-stroke, because of its tendency to separate from the gasoline.
• By growing corn for ethanol, farmers reduce the land being used to grow corn for food, raising the consumer price of corn.
• Ethanol is highly corrosive, forcing auto manufacturers to use more expensive stainless-steel components.
