Did you know that a leaky gas cap can lose up to a gallon of gas every 15 days through evaporation? That is equal to approximately two tanks of gas each year. Or, put into other terms, that equals 30 gallons of gasoline and 200 pounds of evaporative emissions, which adds significantly to the amount of ground-level ozone in the air.
Now you may be wondering, “what is ground-level ozone?” Ground-level ozone is created when emissions from industry, automobiles, and other gas powered engines mix with sunshine, which causes a chemical reaction, creating a harmful, ground-level pollutant. Ground-level ozone is not to be confused with the ozone layer in the atmosphere, which protects us from UV rays.
Although automobiles are just one source of ground-level ozone, it has been determined that one of the simplest ways to make a significant impact on pollution levels is to replace faulty or missing gas caps. According to the U.S. Car Care Council, 147 million gallons of gasoline could be saved if everyone in the U.S. replaced their faulty gas caps. In Colorado alone 3,200 cars per month fail the gas cap portion of their emissions test due to faulty or missing gas caps. By replacing each of these caps the Denver Metropolitan area could reduce emissions of volatile organic compounds (VOCS) by 2.5 tons per day!
So what can we do? This summer when you go in for an emissions test at any Envirotest emissions testing center, your car will undergo a gas cap test. Anyone who fails will receive a $10 coupon to Napa Auto Parts to buy a new gas cap. Vehicles that fail are required to retest, but can do so free of charge within 10 days of the original inspection. Brian Marsh, general manager for Envirotest Systems says of the program, “Not only will customers with failing caps receive an essentially free new cap, but also the new cap is going to save them money in the long run.”
