E85 is a type of 'Flex Fuel' that consists of a gasoline and ethanol mix - the ethanol is effectively made from corn, which is more sustainable than regular gasoline. E10 and E15 are gasoline with 10%-15% added ethanol, while E85 means it should have 85% ethanol with just 15% gasoline. As RacerX says, not all cars can use E85 (or other

https://www.autoblog.com/article/what-is-flex-fuel/

E85 Fuel. E85 is a blend of gasoline and denatured ethanol containing up to 85 percent ethanol and is the highest ethanol fuel blend available in the market. E85 can only be used in flex fuel vehicles (FFVs) which are specifically designed to run on this fuel or any gasoline or ethanol blend ranging from E0 to E85. Much like diesel fuel, E85 is

While E85 is also high octane, it is slightly diluted with 15% gasoline and registers at 105 octane or more. However, E85 has a 27% lower heating value than E0 gasoline, meaning you have to use more of it to get the same BTUs. While this contributes to decreased gas mileage, studies show it depends on the vehicle, with a decrease between 6% and

E85 should only be put in certain vehicles, called flex fuel vehicles (FFVs), which have a fuel delivery system and engine that are designed to use it. Many drivers already own a FFV and do not even know it! To check if a car is a flex fuel vehicle, see U.S. Department of Energy's (DOE) fuel economy site or simply look for a few signs:

A: Anytime you see gasoline with an E prefix, that indicates the fuel contains a given percentage of ethanol. So E10 would contain 10-percent ethanol, E30 is 30-percent ethanol by volume and so on. This makes E85 a fuel with 85-percent ethanol and 15-percent gasoline. Along these same lines, E0 would indicate no ethanol is added to the gasoline

2. Vehicles running on flex fuel have less "knocking" and "pinging.". E85's higher octane helps improve the balance of air and fuel during combustion, which cuts down on the tendency for the engine to knock . 3. Flex fuel/E85 gas keeps the engine clean. Like most alcohols, ethanol is an effective cleaning agent, which means that the

E85, also called flex fuel, is a fuel blend that uses a mixture of ethanol and gasoline. Depending on the season, your region, and its availability, E85 fuel will be made up of anywhere between 51 and 85 percent ethanol, with the rest being traditional gasoline. During the colder months in certain regions, the level of ethanol in E85 will be

https://www.autopadre.com/blog/can-we-mix-e85-flex-fuel-with-regular-gas
One major disadvantage of using E85 is that you'll get less mileage on your vehicle. While E85 has better anti-knocking properties that can increase engine power and an octane rating of 100 to 105, the engine has to burn 20-30% more fuel to match the rates of regular gas. Simply put, E85 doesn't last as long and offers poor mileage.

E85. E85 is a nominal blend of 85 percent ethanol and 15 percent gasoline that is an alternative fuel for automobiles. today's California reformulated gasoline contains from 6 to10 percent ethanol. the actual ethanol content of E85 can vary depending upon the month of the year and geographical location, and may be as little as 70 percent ethanol.

Purse control. Ethanol produces less energy than gasoline-only fuel. This means an engine needs more ethanol in the combustion chamber to produce the same energy as regular gas. Flex-fuel vehicles have a higher purse range in the fuel injection, allowing an extra 40% liquid fuel in the air-fuel mixture ratio.
