ethanol

AAA Oklahoma says more than 400,000 state residents will travel at least 50 miles over the Labor Day holiday weekend – the highest number since 2008.

Spokesman Chuck Mai said 96 percent of that figure will travel by car, and even though gas prices are up about $0.20 since August 1, he thinks many drivers are encouraged by gas prices about $0.19 below the 2015 Labor Day holiday.

It took Sen. Ted Cruz to finally persuade me to answer a riddle that's bothered me for years. Suppose somebody yanked away the law that currently props up the nation's ethanol industry, as Cruz has proposed. What would actually happen?

What does pure gas do that the ethanol can’t? KOSU’s Quinton Chandler finds the answers and explains how federal standards may take away our choice between the two types of gas.
