The key to any hustle is a believable story. It’s no different with fuel-saving flimflams, which often claim to exploit some small, overlooked factor that automakers or oil companies don’t want you to know about.

Four of the five devices showed up, and we tested each in a Mazda 3 and a Jeep Grand Cherokee at steady speeds—35 and 70 mph—on the oval test track at Chrysler’s Chelsea proving ground. A ScanGauge II tool (www.scangauge.com), which plugs into a vehicle’s OBD II port, provided accurate average-fuel-economy measurements. The results?  Well, we hope they don’t surprise you.

I want to see a picture of the fool who purchased this.

FUEL DOCTOR FD-47
$59.99 (www.fueldoctorusa.com)
The Claim: Plugged into the cigarette-lighter socket, “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.”

btw, I always get on to my wife about reading Yahoo articles. Most of them are literally just like trash magazines. :laugh2:
