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.Pros• 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.Cons• 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.When should you use premium vs. regular gas? From the U.S. Department of Energy https://www.fueleconomy.gov/feg/octane.shtmlIf your car manufacturer requests higher octane gasoline - use it!Is your car under recall? https://www.nhtsa.gov/recalls Hosted on Acast.
