About FD-47:
The FD-47 increases a vehicles miles per gallon (MPG) by up to 25% through power conditioning of your vehicles electrical systems. Conditioned and clean power allows your vehicles electronic control unit (ECU), fuel injection and engine timing equipment to operate more efficiently giving you increased gas mileage. When the vehicles engine runs more efficiently it will require far less fuel, produce more power and have reduced exhaust emissions (reduced CO2).
As a vehicle gets older, the power systems often will generate and experience more electrical noise or electrical interference. This electrical noise can have many detrimental effects on the vehicles systems and decrease their fuel efficiency. The FD-47 simply plugs into your lighter socket/power port and the power conditioning qualities of the FD-47 help to reduce and remove this noise and to restore your vehicles fuel efficiency. If your vehicle is designed for high performance or modified for increased power this unit may not have any effect on your fuel mileage. For maximum results use on vehicles that are over two years old.
It sounds too good to be true! Fuel Doctor is so confident in its product that it offers a 30-day money back guarantee as a pledge to your satisfaction. This is more than enough time to try the FD-47 and experience the positive results yourself.
Why don't car manufacturers already have this technology? They do and have been for some time, in fact there is filtering of the power systems throughout the vehicle. However with time, tolerances change, noise levels increase, and connections weaken or loosen from vibrations. The FD-47 helps to condition the power back to where it was when the vehicle was brand new.
Should I leave my FD-47 plugged in at all times? Yes. For optimal performance, you should leave it plugged in at all times. It will not drain your battery even if the lights are illuminated when the vehicle is off.
If you have security concerns, you can unplug the FD-47 after you leave your car and plug it back in when you return.
How do I know if my Fuel Doctor FD-47 is working? Both green lights will be illuminated when the FD-47 is working. It is perfectly normal for the lights to stay on even with the ignition off (it will not drain your battery)
If the red light goes on, it means that your battery has dropped below 10.5 Volts and you should check the battery as soon as possible. How do I know if my Fuel Doctor FD-47 is working?
