55 MPH = Optimal Fuel Efficiency

Samerwriter ran a relatively unscientific study on fuel efficiency [3] where he plugged the ScanGauge into his car and monitored its fuel efficiency against his speed. He confirmed an often stated idea that driving around 55 MPH resulted in the most efficient use of fuel and that efficiency dropped significantly as you approached higher and higher speeds. Despite it’s unscientific nature and the fact that the idea was widely accepted anyway, seeing real life data from a real person, and not some group sponsored by someone else, is pretty eye opening.
