If it's been a while since your car was tuned-up, you're probably not optimizing your mileage.

Tune-ups involve checking and adjusting the systems in your vehicle that relate to proper fuel combustion. When these components malfunction because of inadequate maintenance, your car's emissions increase and its drivability and gas mileage will suffer.

By tuning up an under-maintained vehicle, you may improve your fuel economy by up to 10 percent or more, which can result in an annual gas savings of more than 50 gallons. At today's gas prices, that could mean an extra $150 at the end of the year.
