The Mythbusters (Adam Savage and Jamie Hyneman), a crew that carried out 2 experiments, tested whether the dirty car was more fuel efficient than the clean car and whether the dimpled car with clay was more fuel efficient than the smooth car with clay, after trying to prove a myth. The myth states that the dirty car would be more fuel efficient because the dirt on the car would create a golfball effect on the surface of the car, which would make the car more aerodynamic and thus more fuel efficient. In reference to the myth, the first experiment was to test the fuel efficiency of a car, that was altered clean and dirty. To test it, the Mythbusters used a fuel tank, attached to the side window, that measured the distance of fuel level between, when the car crossed the starting line and when it completed a mile at a constant speed of 65 mph.…show more content…
The average of the trials revealed the results of the fuel efficiency, each type of car had, which was that the dirty car traveled 24 miles per gallon of fuel and the clean car traveled 26.4 miles per gallon of fuel, that concluded with the clean car being 10% more fuel efficient than the dirty car. However, the crew later decided to test the theory of the myth: that the golf ball effect on the surface of a car would make the car more fuel efficient. To do this, they tested with a smooth car and a dimpled car both covered in clay and did the same number of trials (5 trials) and the same speed of driving the car (65 mph) as the first experiment, but changed the technique of measuring the fuel efficiency. The Mythbusters used a fuel cell that measured the weight of the fuel in grams, when the car crossed the starting line and when it completed a mile instead of the fuel tank. The weight difference between the 2 measurements was converted from grams to miles per gallon for each mile, 5
