Ethanol contains about one-third less energy than gasoline. So, vehicles will typically go 3% to 4% fewer miles per gallon on E10 and 4% to 5% fewer on E15 than on 100% gasoline.

Do you get better gas mileage with no ethanol?
Pure gas gives drivers better mileage. This is because gas mixtures like E10 and E15 have less free energy due to the added ethanol. ... Compared to regular and premium gas mixtures, non-ethanol gas is better for your overall mileage.
Does ethanol improve mileage?
Fuel Economy and Performance
If they were optimized to run on higher ethanol blends, fuel economy would likely increase as a result of increased engine efficiency. Ethanol also has a higher octane number than gasoline, which provides increased power and performance.
How much does 10 ethanol affect gas mileage?
The Environmental Protection Agency says E10 lowers mileage approximately 3 percent, which would drop your mileage from 19.6 to 19.0 mpg.
Does 93 octane have ethanol?
Yes! Generally a 10% blend of ethanol. When you see 91 it is generally 100% gas without ethanol. Ethanol has an octane rating of 110.
Does premium gas contain ethanol?
Premium gas doesn't provide any more power or contain better additives than regular gas, and it contains the same amount of ethanol as other grades. It just resists detonation (knock) better than lower-octane gas—nothing more, nothing less. ... If so, keep using 89-octane to regain some power and save your engine.
Is ethanol gas good for cars?
Ethanol can cause several types of damage to the engine in your vehicle. Your vehicle's fuel intake components can be damaged. In addition, ethanol can cause damage to the fuel pump in your vehicle. ... Your engine can actually be destroyed if the ethanol content in the fuel you use is too high.
What are the pros and cons of ethanol?
Ethanol. Pros: Reduces demand for foreign oil, low emissions, high octane, and can potentially be produced from waste materials; existing cars can use 10-percent blends (called E10), and more than 8 million cars already on the road can use E85. Cons: Twenty-five percent lower fuel economy on E85 than gasoline.
What is wrong with ethanol in gas?
Because it is an alcohol, ethanol dries out the rubber components in a fuel system. ... This leads to cracking and brittle fuel lines, floats, seals and diaphragms.
Is it OK to put 10 ethanol in my car?
Ethanol at 10% is safe for your engine on the long run. I have a 1988 car running on E100 since it was manufactured an the engine is running ok. The main issue with ethanol lies on the corrosion it causes to carburetor bowls.
Is E85 better than 93?
E85 has an octane rating higher than that of regular gasoline's typical rating of 87, or premium gasoline's 91-93. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts.
Do you get less miles per gallon with E10 fuel?
Analysis by the DfT found fuel economy could be reduced by between one and two percent. ... RAC fuel spokesman Simon Williams said: “Those with E10 compatible cars will unfortunately find they are getting fewer miles to the gallon as the fuel is less efficient than E5 fuel, due to it containing 5 percent more ethanol.”
How long does it take for ethanol to separate from gas?
“In a small engine fuel tank in a constantly high-temperature, high-humidity environment, it takes three months or longer for E10 and other ethanol blends to take up enough water for phase separation,” the study found.
Is ethanol bad for car engines?
— Efficiency: Ethanol-blended fuel's lower energy efficiency may reduce fuel economy of your engine. — Stalling: Ethanol can cause engine stalling if the water in the ethanol separates from the gasoline and floods the engine. ... — Clogging: Ethanol can loosen debris in the fuel line that leads to clogs.
What is the main advantage of ethanol over gasoline?
Ethanol adds two to three points of octane to ordinary unleaded gasoline, so it boosts the performance of your engine. Because of its high oxygen content, ethanol burns more completely than ordinary unleaded gasoline and reduces harmful tailpipe emissions. Ethanol prevents gas line freeze-up.
