Earlier this week API highlighted new research by the Coordinating Research Council (CRC) on serious potential problems with vehicle fuel systems when operated on E15 fuel – gasoline containing 15 percent ethanol.

In addition to CRC’s research, we want to call attention to a recent paper from Oak Ridge National Lab (ORNL) that was published by the Society for Automotive Engineers (SAE).  This study examined the effects of E15 on malfunction indicator lights (MIL), also known as “check engine lights.”

There’s new research showing E15 (15 percent ethanol) fuel could damage vehicles, potentially stranding motorists and/or saddling them with expensive repair bills – one of a number of reasons the Renewable Fuel Standard (RFS) should be scrapped. Following on a report last spring that said E15 could damage engines and cars and trucks, the Coordinating Research Council (CRC) has a new study that found E15 can mess up fuel pump systems and fuel measurement systems, potentially affecting “millions and millions” of vehicles, Bob Greco, API downstream and industry operations director, said in a conference call with reporters.

Nearing the end of the 2012 it’s worth noting that some things about the Renewable Fuel Standard (RFS) haven’t changed: Commercially available cellulosic biofuel still isn’t being produced, and the nation’s refiners still don’t know how much biofuel they’ll have to blend next year under the RFS mandate. Other than that, no worries, right?

Last week’s call by AAA for a halt in the sale of gasoline containing 15 percent ethanol – because E15 could damage vehicle engines and void car manufacturers’ warranties – triggered the kind of response you’d expect from the Renewable Fuels Association, ethanol’s biggest supporter.

A recent study suggested ethanol might be the source of corrosion in underground tanks used to store ultra low sulfur diesel fuel. Battelle, which conducted the study, checked a number of hypotheses, weighed the data and evidence and came to a conclusion pointing to ethanol
