E20 study finds no drivability issues with NFFV

A just released study out of Rochester found not issue with 10 different Non-flexible fuel vehicles that ran this blend for 100,000 miles each! This study is being utilized by the Federal Government's Department of Energy in an attempt to justify the upward boost of permitted ethanol blending from 10% to 15%. What is the wait? I'm currently driving a E230 blend in my vehicle. The weather is spring like and I'm going to be changing my winter tires for the low rolling resistance tires sometime in the next few weeks.
