Executive Summary Report Ethanol Study by Harris Interactive from July 31-August 2, 2013

September 11, 2013

Below is the executive summary report for the market size study, conducted by Harris Interactive® via its QuickQuerySM online omnibus service from July 31-August 2, 2013.


Survey Methodology

This survey was conducted online within the United States between from July 31-August 2, 2013 among 2,040 adults ages 18 and older by Harris Interactive on behalf of OPEI via its Quick Query omnibus product. This online survey is not based on a probability sample and therefore no estimate of theoretical sampling error can be calculated.



Specifically, OPEI sought to learn:


  • What are the first things people notice when arriving at the fuel pump?
  • Do they know there is ethanol in gasoline?
  • Do they fill up their portable gas tank with the same fuel used to fill their vehicle?
  • Do they use the least expensive grade of gasoline whenever possible?
  • When they fuel up their car at the gas station, do they check the fuel pump for any warning labels?
  • Do they assume that any gas sold at the gas station is safe for all of their cars, as well as boats, mowers, chain saws, snow mobiles, generators and other engine products?
  • Do they know it is illegal to put higher level ethanol gas (i.e., anything higher than 10 percent ethanol) into engines such as those in boats, mowers, chain saws, snow mobiles, generators and other engine products?


OPEI commissioned a four-question online omnibus study to explore these issues. For the entire report, click here.
