Why Should I Run Ethanol?

Ethanol is the highest-performing fuel available, and it’s available at the pump. Ethanol is commonly referred to as E85, which is typically the highest blend at the pump, and not only gives your vehicle more power but burns cleaner and cooler. Increase your vehicle’s horsepower and torque with the PROFLEX Commander and ethanol.
