Minnesota Study Finds E20 Passes Materials Compatibility and Driving Performance Tests
5 March 2008
Increasing the amount of ethanol blended into gasoline from 10% (E10) to 20% (E20) does not present problems for materials used in current vehicles or fuel dispensing equipment and provides similar power and performance, according to a new study released Wednesday by the State of Minnesota.
This initial scoping study for E20 consists of three main areas of investigation: materials compatibility, drivability, and emissions. The emission testing is still ongoing and the results will be released as soon as the testing is complete.
Key findings of the report include:
The effects of 20% ethanol blended fuels do not present problems for current automotive or fuel dispensing equipment.
The drivability study showed that E20 provided similar power and performance to E10 ethanol blended fuel throughout the entire calendar year, which included a broad range of ambient weather conditions.
Based on the materials compatibility and drivability testing results of this scoping report, there are no issues that would prevent moving forward with the comprehensive testing required to certify E20 as a federally approved motor fuel.
