MYTH: Ethanol clogs my carburetor.
Reality: Ethanol is an effective solvent and can help remove gum and deposits left by years of gasoline use. This is one of the reasons alcohol is often used as an additive in today’s fuel.
MYTH: My fuel system is harmed by ethanol.
Reality: Aromatics in today’s gasoline are generally more aggressive to rubber than those of the 60s and 70s. Extended storage without proper treatment or overuse of certain additives may contribute to deterioration of fuel system components.
MYTH: Using ethanol reduces my car’s performance.
Reality: Ethanol is one of the most economical performance fuels on the market. That is why it is used by every car in NASCAR’s three premier series. Many teams have reported an increase in horsepower and no decrease in mileage when using ethanol-enhanced fuel.
Most all unleaded gasoline in Kentucky is an E10 blend (10 percent ethanol and 90 percent unleaded gasoline) which reduces GHG emissions and our need for foreign oil. Possible exceptions include premium blends, aviation and boating fuel.
All motor vehicles manufactured since the 1970s can run on E10 without engine modifications. E10:
Higher Ethanol Blends E15, E20, E30, E40, E85
Each blend is indicated by the percentage of ethanol it contains (i.e. E30 is comprised of 30 percent ethanol and 70 percent gasoline). E15 has been approved by the EPA for use in 2001 or new vehicles. Blends higher than 15 percent ethanol are approved for use in Flex Fuel Vehicles (FFVs) only. These new ethanol blends offers consumers with FFV’s another choice at the pump.
