I hafta say, that was a pretty low quality article in general.

I can think of 6 more mpg myths:

1. Studies have shown that drilling holes in the bottom of your gas tank leads to lower gas mileage, not higher.
2. All other things remaining equal, replacing a Prius with an H2 Hummer rarely results in less money spent at the pump.
3. When pumping your own gas into your car, there is a way to hold the nozzle trigger so that once your tank is full, an additional gallon or more spills on the ground. Contrary to common belief, this practice results in more gas wasted rather than less.
4. If you drive a 4 wheel drive pickup truck as a highway commuter vehicle, driving at 90 mph can sometimes waste gas. Also at these speeds, the high-lift suspensions, oversize off-road tires, and that bank of off-road spotlights all increase this effect.
5. If when sitting at red lights, instead of letting your engine idle or even turning it off, revving your engine to above redline just to hear the valves float may actually lead to higher fuel consumption.
6. Disconnecting half of the spark plug wires only causes your engine to run rough and results in no savings what so ever.

I hope this was helpful. Maybe othes can fuel this thread with even more gas-saving myths.
