The Car Care Council offers these fuel-saving tips:
- Vehicle gas caps — About 17 percent of the vehicles on the roads have gas caps that are either damaged, loose or are missing altogether, causing 147 million gallons of gas to vaporize every year.
- Under inflated tires — When tires aren’t inflated properly it’s like driving with the parking brake on and can cost a mile or two per gallon.
- Worn spark plugs — A vehicle can have either four, six or eight spark plugs, which fire as many as 3 million times every 1,000 miles, resulting in a lot of heat and electrical and chemical erosion. A dirty spark plug causes misfiring, which wastes fuel. Spark plugs need to be replaced as recommended by the manufacturer.
