Boosting performance

Ethanol-enriched fuels (E10 is the most common in the United States) meet or exceed all performance standards for U.S. vehicles, including:

  •  Heat Energy: The heat energy of all gasoline-based motor fuel varies somewhat by formulation, region and time of year.
  • Ethanol burns slightly cooler than straight gasoline: on average, a gallon of 10% ethanol-enriched gasoline contains about 112,000 BTUs of heat energy, compared to 114,000 BTUs for straight gasoline.
  • Cooler combustion temperatures contribute to increased engine longevity.
  • Volatility/Vapor Pressure: Ethanol-enriched fuel meets all applicable vapor-pressure standards
    • U.S. Environmental Protection Agency (EPA).
  • Octane: Adding 10% ethanol to regular unleaded gas typically increases the octane rating from 87 to 89.5 or higher.
    • This boost can reduce knocking and pinging, and allows cars with knock sensors to gain increased power.
  • Phase Separation: Ethanol-enriched fuel is far more tolerant of water contamination than regular gasoline
    •  Preventing phase separation and water at the bottom of the tank.

Fuel-Systems & Engines Compatability

  • The issues of ethanol compatibility raised in the 1970's have long been resolved .
  • Since 1980, modern fuel lines have been fully compatible with ethanol.
  • Since 1990, all U.S. gasolines have contained detergents to control fuel-tank deposits that can clog fuel filters.
  • And when it comes to induction-system components, ethanol blends work well with fuel injection systems and older carbureted vehicles.
  • Because ethanol burns cleaner than regular gasoline, it leaves fewer deposits on intake valves and combustion chambers.
  • Otherwise, ethanol-enriched gasoline performs in much the same way as regular gasoline.

Environment

  • Because ethanol-enriched gasoline contains more oxygen than regular gasoline, it burns more completely, which reduces carbon monoxide emissions.

Localized Economics

  • Ethanol is produced in the country where it is being used this creates local jobs.

  • Ethanol helps reduce our dependence on foreign energy sources.
