A study by a team from UC Riverside has assessed the potential of increasing ethanol content in California reformulated gasoline (CaRFG) by investigating the exhaust emissions from a fleet of 20 Tier 3 light-duty vehicles. A baseline CaRFG E10 (10% ethanol by volume) fuel was splash-blended with denatured ethanol to create an E15 fuel.
