In an effort to assist US corn farmers from negative tariff repercussions, the Trump administration has approved lifting the ban that the EPA had imposed. The removal of the ban allows for greater use of ethanol all year long and allows the current 10% mix to now be increased up to 15%. The corrosive nature of ethanol will require fuel pump and delivery infrastructure to be replaced prior to sales.
I was already not happy with the current 10% ethanol contamination in our gasoline, which lowers fuel mileage of consumers by up to 15% over straight gasoline. Because ethanol is cheaper to produce than gasoline, consumers may notice that the price at the fuel pump appears cheaper on E-15 fuel. The slightly cheaper price tag at the pump will appease many people who don't know they're really paying more for effectively, watered down fuel.
As for for myself, I am no longer directly affected by this ethanol nonsense since both of my vehicles are powered by diesel and even my lawn equipment has long ago been switched from gas to all electric.
If you are a highway warrior like myself you should already be driving a diesel car or truck. However, if you routinely drive just within the city at speeds under 50mph, do yourself a favor and avoid the (clean) diesel options and stick with gasoline vehicles or (leasing) an electric car. Clean Diesels, with today's emissions equipment are now, more than ever, made for longer duration, higher speed driving.
