Be rigorous about changing your car’s fluids and filters during the winter months. Your car’s older engine will thank you for it! Remember to change the oil and oil filter every 3,000 to 5,000 miles. Use the recommended oil viscosity range for winter. 5W-30 motor oil flows quicker in cold weather than 20W-50. Most vehicle manufacturers recommend 5W-30 oil for year-round protection.
