E85 is a great alternative fuel that supports cleaner emissions and renewable energy. Because ethanol has a lower energy content than regular gasoline, your vehicle injects more fuel per cycle when running on E85. As a result, fuel consumption typically increases by about 15–30%, depending on your vehicle, driving style, and the exact ethanol blend.

Good to know: Your vehicle’s onboard computer may not fully account for this increased fuel flow, so fuel economy readings might appear slightly different than expected.
