It's been a good summer for American's traveling on the roads – with low gas prices in multiple states, according to AAA. But refining jobs could be at risk and consumers may face higher fuel costs if the White House advances proposals to dramatically increase biofuel mandates.
Higher-ethanol fuels can cause engine damage for vehicles that aren't designed for it, and most vehicles aren't. Nearly 70 percent of vehicles on the road today were not designed to run on fuel with 15 percent ethanol volume, known as E15. Using it can void warranties and require costly repairs. Plus, it's less energy dense than ethanol-free gasoline, requiring more frequent fill-ups. That's why the Renewable Fuel Standard (RFS), which mandates yearly ethanol quotas, is so bad for consumers.
