Cars get less efficient as they age. The FD-47 Fuel Doctor is a device that conditions the electrical system of your vehicle to be more efficient. When the electrical system is working better, the engine requires less fuel and produces more power. It’s easy to install, just plug it in to the lighter socket in the front of your car. Better fuel efficiency is that simple!
