1. Let your car warm up for only 2-3 minutes.
More than a minute or two cause long-term wear problems on the car. Try driving it slowly for the first few miles, then drive it normally.
2. Lift up your wiper blades when parked.
In order to prevent your wiper blades from freezing to the glass, leave your wiper blades up when parked unless there is heavy wind in the forecast. That way, you can prevent damaging the transmission for the wiper blades.
3. Always keep your tank at least HALF full.
This would help eliminate condensation issues in the fuel. If you get too much water in the fuel, you could end up with a fuel line freeze-up situation.
4. Make sure your windshield washer reservoir is full.
On a snowy day, you can easily go through half a gallon or more of windshield washer fluid trying to keep your windshield clear.
5. Use cooking spray to prevent your doors from freezing shut.
Just spray on the edges of the doors then rub them down with a paper towel.
