The EPA approved the sale of a cheaper fuel, but can your car run on it?

The EPA has approved the sale of E15, a fuel blend containing 15 percent ethanol that costs less than traditional regular unleaded gasoline. The cheaper fuel option comes with a significant catch: many vehicles on the road cannot safely use the higher ethanol blend without risking engine damage. E15 was designed to reduce fuel costs for consumers and lower emissions by increasing ethanol content, but vehicle compatibility remains a major barrier to widespread adoption. Drivers must check their manufacturer's specifications before filling up with E15, as older vehicles and some current models are not certified for the blend. The approval highlights a tension between environmental and cost-saving goals and the practical limitations of the existing vehicle fleet.
