|Fuel economy is the number of miles/kilometers per gallon your car gets and can vary depending on how you maintain and drive your vehicle. Low tire pressure, clogged air filter, worn or fouled spark plugs can lower gas mileage. Aggressive driving can also reduce gas mileage – as much as 33% on the highway and 5% on city streets – as does excessive idling, driving over the speed limit and using the car’s A/C system.Why do I Need This Service?A properly maintained vehicle can improve its effeciancy and save money. Things to consider:
Tires can lose pressure due to seasonal temperature changes and prevent your vehicle from getting maximum performance and mileage.
Air filters can become clogged with dirt, dust or bugs, which choke off the air and create a rich mixture that wastes gas and causes engines to lose power.
Worn or fouled spark plugs can cause the engine to lose power or misfire and waste fuel.
Tire pressure should be checked at least monthly, including the spare. Underinflated tires can lead to higher fuel costs by as much as three to five cents per gallon.
The air filter should be inspected at each oil change, which is recommended every 3,000 miles or per the owner’s manual, and replaced when dirty, torn, water or oil soaked. Replacing a clogged filter can improve gas mileage by as much as 10%.
A routine checkup will include checking the spark plugs, which have a replacement interval ranging from 30,000 to 100,000 miles per the owner’s manual, replacing any other ignition system and/or emission systems parts that may be needed, replacing the fuel and air filters, adjusting the ignition timing and idle speeds (if applicable), and ensuring the onboard computer control system is working properly. A tune-up can improve gas mileage by an average of 4%.
