We expect attacks from ethanol boosters over E15 gasoline, fuel that contains 15 percent ethanol, because their stated mission is to promote more ethanol use.  But, unfortunately for them, the science is clear; E15 has been shown to cause damage in some engines and fuel systems.

Pointing this out, citing tests by the Coordinating Research Council (CRC), an organization that’s the gold standard in terms of automotive research, has drawn some fantastic claims, most recently that the E10 (10 percent ethanol) “blend wall” – the point at which there isn’t enough E10 being sold to accommodate all of the ethanol mandated by federal law – doesn’t actually exist, more on that below.
