Vehicles need extra attention when the temperatures drop. The non-profit Car Care Council offers six quick tips: Keep the gas tank at least half full. Check the tire pressure, including the spare. Have the exhaust system checked for carbon monoxide leaks. Give the car time to warm up. Change to low-viscosity oil. And use cold weather washer fluid and special winter windshield blades. Drivers should also stock an emergency kit. For the latest car care news or to order a free Car Care Guide, visit car-care--dot--org.
