Oil change
Check the owner's manual to see if your driving habits are considered to be "severe service." This type of driving requires more frequent oil changes, warns the Council. Have the oil changed accordingly, usually every 3-5,000 miles. For less wear and tear on the engine, drivers in cold climes (sub-zero driving temperatures) should drop their oil weight from 10-W30 to 5-W30. Your mom and dad would probably suggest simply moving to someplace warmer.

Four other musts
The battery and exhaust system are other "must check" items. These should be examined using professional equipment. Make certain the heater/defroster are working properly and keep the gas tank full. In addition to staying ready for the road, a full fuel tank decreases the chances of moisture forming in the gas lines and possibly freezing.

Exterior concerns
Now for the outside of the vehicle: tires, lighting and wipers. Both tire tread and tire pressure should be checked weekly. If snow and ice are a problem in your area, consider special tires designed to grip slick roads. Lights should be inspected regularly. Check to see that bulbs are illuminated, and headlights are properly aimed. Finally, replace wiper blades every six months. Consider special snow blades if the weather dictates.

Emergencies
Even the most meticulously maintained vehicle can develop problems on the road, especially during inclement weather. That's when it pays to be prepared for an emergency. Tapping the Trunk - Use that big space for something more than a spare tire (which, incidentally should be properly inflated, just in case). Pack items that would be needed if you got stranded for a several hours. A cell phone (with a car charger) is a good start. Also include the following: ice scraper, windshield de-icer, flashlight, whisk broom, blanket, extra clothes, candle/matches, bottled water, snacks, needed medication.
