Yes. It is usually between 2%-4% less fuel efficiency. Ethanol content in gasoline is measured as a percentage of volume, and most gasoline in the United States contains 10% ethanol (E10). In certain parts of the country, you can find gasoline with up to 85% ethanol (E85).
- Ethanol typically has lower energy density than petroleum-derived fuels, meaning that while ethanol carries less fuel per unit of volume, it releases more carbon dioxide per gallon.
- Ethanol also has a lower stoichiometric air-fuel ratio compared to gasoline, requiring more fuel to be used per unit of air during combustion.
- Other factors, such as fuel system compatibility and engine design, can also impact fuel efficiency.
Which gas stations sell pure gas?
Not every gas station sells pure gasoline, however pure gasoline is still widely available. To find pure gas, you can:
1. Use the Pure Gasoline USA website or app to find a station near you.
2. Look for the "pure gas" or "non-ethanol" label on the pump.
3. Ask the gas station attendant if they sell pure gasoline.
