A 20pc blend of ethanol in gasoline appears to be no harder on vehicles than is regular gasoline, according to a Minnesota State University (MSU) study.
Tests on raw materials — the metals, plastics and rubber-like substances — found no problems with the E20 blend.
Likewise, fuel pumps using regular gasoline, E10 and E20 were run for 5,000 hours and no unusual wear and tear was evident.
The study, part of a $US497,000 grant to the university, is led by Bruce Jones and Jim Rife in MSU's automotive engineering technology department.
