Replace and Repair
Worn or dirty components can significantly impact your vehicle’s ability to use fuel efficiently.
* Replacing a dirty air filter – a five-minute job most consumers can do themselves -- can improve gas mileage by 10 percent, according to the National Car Care Council. This can add up to $198 annually. Change the air filter at least once a year, or every 12,000 miles. If you live in a high pollution or dusty region, you may need to change the filter more often. Just one teaspoon of dirt in the engine can cause more wear than 75,000 miles of normal driving,
* Oxygen sensors help your vehicle properly detect and adjust the mixture of air and fuel going into the engine. If a sensor is faulty, it can shave up to three miles per gallon off your car’s fuel efficiency and cost you about $239 a year.
* Bad spark plugs can leave you sitting with a car that won’t start, but worse yet are worn spark plugs and spark plug wires that could cost consumers up to $100 per year in wasted fuel.
Refine Fuel Flow
Many motorists cringe at the cost of gas, but never think about fuel once it enters their tank. But it’s important to ensure that the components in your vehicle’s fuel system are all working perfectly – from the gas cap to the fuel line.
About 147 million gallons of gas vaporize each year from the more than 40 million vehicles on the road with damaged, loose or missing gas caps, according to the Car Care Council. Make sure your vehicle’s gas cap is not damaged, loose or missing. Consider a locking gas cap to ensure a proper seal and to protect your fuel from theft by siphoning.
Debris and deposits in a vehicle’s fuel lines can clog them and hinder fuel efficiency. Periodically adding a fuel system cleaner to your gas tank can help ensure a cleaner engine.
Don’t Ignore the Engine Light
How many times has it happened to you? You’re on your way somewhere, in a hurry, when the “check-engine” light comes on. You know you probably should stop, but instead take a chance that the car will keep running at least long enough to get you where you want to go – this time.
“Of the 236 million vehicles on the road, an estimated 25 million to 35 million are operating with their check-engine light on,” says Brett Easley, certified mechanic and vice president of merchandising for AutoZone automotive retail outlets. “As a free service, many automotive retailers will help drivers identify the possible reason the light came on.” AutoZone provides free code retrieval reports that can help identify the possible cause of the alert, and aid in referring customers to trusted repair shops in their area.
