Fuel Doctor – Long Term Test Results

May 2nd, 2011 – At this point the Fuel Doctor has been installed and tested for only a little more than 5,300 miles. During that time I have tracked my fuel economy using both my Scanguage and the tried and proven method of miles driven divided by gallons pumped to full. Each time I refuel I try and use the same pump in order to minimize pumping variances and I always fill the tank full.

Here is the raw data from the testing so far:

March 15th, 2011 – Prior to installation of the Fuel Doctor I was averaging 14.5 Miles Per Gallon for each tank of fuel. These numbers were firmly established over a period of several months. At the time of the commencement of testing I was refueling at one-quarter of a tank of fuel driving the same route seven days a week with unvarying weather and traffic conditions. In order to maintain consistent test conditions I used cruise control to and from work.

Immediately upon installation of the Fuel Doctor I recorded an increase of a little more than one and a half miles per gallon. The average per tank miles went from 14.5 MPG to 16.1 MPG – garnering an improvement of nearly ten percent. This improvement was phenomenal, but I viewed it with caution and reservation.

February 15th, 2011 – The Fuel Doctor arrived at my house securely packaged in bubble wrap. It is a compact device with no wires or connecting cables. Installing the Fuel Doctor was simple and straightforward – it plugs into the cigarette lighter. I was surprised by how small the Fuel Doctor is but it turns out that the small size is a good thing as it does not stick out far enough to get snagged on anything that I am constantly throwing in the little tray beneath the cigarette lighter.

Prior to the arrival of the Fuel Doctor I did some research on the internet – most of what I found disputed the efficacy of the product. I found You Tube videos in which self-proclaimed electrical engineers dissected the product and gave lengthy and involved technical explanations as to why the Fuel Doctor could not possibly work. A simple Google search on the Fuel Doctor returned a mountain of websites ranging from “does it work” and “how does it work” to “Fuel Doctor scams.”

Fuel Doctor Review – Does it Work?

This week we’ll be reviewing the Fuel Doctor, a fuel saving device that I encountered at the 2010 SEMA show last November.

Conducting this review will be Toby K, who runs his own Tundra Fuel Economy blog where he writes about fuel saving devices. Over each of the next five days, you’ll read a post from Toby describing his testing process. At the end, you’ll learn the following:

The Fuel Doctor really worksor at least it did for this specific test.

The Fuel Doctor touts something called “electronic signal conditioning,” and according to their Chief Technical Officer Doug Hungerford, the Fuel Doctor can improve fuel economy in the right circumstances. According to our admittedly small test, it does. Here’s the whole story:

February 1, 2011 – From a very early age I can remember thinking and wondering about fuel economy. While yet still quite young I came to the conclusion that absent drastic change in fuel economy it would be rather likely that we would run out of petroleum in our lifetime. I spend a lot of time thinking about how to improve fuel economy and have tested many of my personal theories and inventions. I have also tested devices or products available for sale to the general public. Some of these devices have worked while others have only served to lighten my wallet. I take nothing for granted and have found in a few instances that the general consensus is off base or completely wrong. I am a hands-on kind of guy and most of what I write about is based on my personal observations and testing.

When Jason contacted me asking if I would be interested in testing the Fuel Doctor for TundraHeadquarters.com and writing a review of the device, I was eager to get started. I must admit to a fair degree of skepticism after reading both how this device is purported operate and in the gains claimed. I know from personal experience that a 10% gain in fuel economy is an impressive improvement. Even so, I will test the Fuel Doctor in as scientific a manner as possible using a Scanguage II and the old reliable pen, paper, and calculator.
