Gas Cap Check and Free Replacement


Race Week Brings Free Gas Cap Checks, Replacements for NASCAR Fans

tl_files/cfca/images/cfca/Events/aggc.jpgNASCAR fans can get their gas caps checked and free gas cap replacements during Roush Fenway Racing’s Fan Appreciation Day.

Co-sponsored by Roush Fenway Racing, Mecklenburg Air Quality Program and the Center for the Environment at Catawba College, the event is scheduled for 8 a.m. to 2 p.m. on Thursday, Oct. 14, at the Roush Fenway headquarters at 4600 Roush Place NW in Concord.


What happens at a gas cap check?

The gas cap check is free and takes less than five minutes to complete. This is what it involves:

  • You are asked to pull up to the site and “pop” your gas cap door for access.
  • Your gas cap is removed and tested for pressure and is given a grade of pass or fail.
  • If the car passes, then you do not need to replace your gas cap, and you move on.
  • If the car fails, then you will be given a free replacement gas cap which will be placed on your vehicle. If your vehicle’s gas cap is not available on site, the team will mail you one free of charge.

Why should you replace your gas cap if it’s leaking?

The Mecklenburg Air Quality Program offers five good reasons for replacing leaking gas caps.

  • Leaking gas caps contribute to air pollution and waste fuel because of evaporation.
  • The U.S. Car Care Council estimates that 17 percent of vehicle gas caps are either damaged or missing, allowing 147 million gallons of gasoline to vaporize every year.
  • Gas caps can leak regardless of the age of the vehicle. The likelihood is higher if vehicle is more than three years old.
  • Every leaking gas cap allows approximately 200 pounds of evaporative emissions to escape each year. That represents 200 pounds of volatile organic compounds, which contribute to ground-level ozone pollution.
  • Thirty gallons of gasoline can be released annually from a leaking gas cap.

Why should you make sure your tires are inflated properly?

  • Tires that are properly inflated to the manufacturer's specifications can improve gas mileage by as much as 3 percent over driving with improperly inflated tires, according to eHOW Cars.
  • A vehicle’s gas mileage decreases by 4 percent for every pound of recommended air pressure that is not in the tire. As the tire pressure decreases in a tire, the tire hugs the pavement more and therefore causes the tires to rotate slower and the car to use more gas.
  • If the nearly 250 million registered passenger vehicles in the United States were only 7 percent underinflated, and brought their tires up to the specified level, together they would save about $23 billion per year, according to a 2005 Department of Transportation study.
