Fuel Doctor ~ Fuel Efficiency Booster for Cars ~ Review

  • Sharebar

I know you hear me tellin’ ya day in and day out about what a tree-hugger I am! I’m always looking for ways to save resources and lighten my carbon foot print. Folks, it’s a MUST! So when the folks from Fuel Doctor USA contacted me about a product they make that saves gasoline simply by being plugged into the lighter of your car I was all ears albeit skeptical!

Wondering how this nifty device works? I was too! Fuel Doctor USA’S FD-47 is simply “plugged in” to the lighter of your car. It significantly changes the automobile’s rate of fuel consumption, saving you money as well as the environment, one car at a time.

Because I’m so NOT TECHY.. I want y’all to see just how easy the Fuel Doctor USA’S FD-47 is to use! This is it! Just plug it into your cars lighter and your set.

Fuel Doctor’s FD-47 is The Fuel Efficiency Booster. The FD-47 increases a vehicle’s miles per gallon (MPG) through power conditioning of the vehicle’s electrical systems. Conditioned and clean power allows the vehicle’s electronic control unit (ECU), fuel injection and engine timing equipment to operate more efficiently. When the vehicles engine runs more efficiently it will require less fuel, produce more power and have reduced exhaust emissions (reduced CO2).

As a vehicle matures, the power systems tend to generate and experience more electrical noise or electrical interference. This noise can have many detrimental effects on the vehicle’s systems and decrease their efficiency. The FD-47 simply plugs into the lighter socket/power port and the power conditioning qualities of the FD-47 help to reduce and remove this noise and to restore your vehicle’s efficiency.


I had to enlist the help of my very tech savvy Hubby the Hubster for this review. He drives 70 miles per day! He was MORE than happy to help since he spends a fortune on gas. He wanted to make pie charts and a ton of graphs but I told him to stick to my old philosophy Keep It Simple Sista. He used the Fuel Doctor’s FD-47 all last week and he is a stickler for recording his gasoline consumption, mpg and all that stuff.
