Batteries aren't necessarily maintenance-free. If you're under the hood checking the oil, give a look to the terminals of your battery; if corrosion or other residue is collecting around them, your battery may not be as healthy as you think. Further, a dirty battery case can not only cause current loss, but also hide bulges or cracks--surefire signs you need a replacement. Remember to use caution when inspecting your battery, or be sure to ask a professional next time you bring your vehicle in for service!

Merry Christmas to all, and to awesome day! Have a safe and wonderfully jolly Christmas!

Do your part! Consolidate short trips; the first few minutes of operating your vehicle create the most pollution. Try to lump your errands in together if you can. Not only is this healthier for the environment, it's healthier for your engine, and your wallet by way of improving gas mileage!

Seasonal Maintenance: Avoid potential leaks or corrosion brought on by falling leaves and twigs that get stuck in the crevices of your vehicle. These affected areas are typically designed for water drainage and air circulation. Left unattended, these seemingly harmless items begin to decompose, which can weaken the integrity of your vehicle's more sensitive areas.
