Warm up your car’s engine before driving in the cold
Engine parts do need to warm up to operate fully, but modern engines warm up faster while you’re actually driving. Additionally, your wheel bearings and transmission need movement to completely warm up. Running your car before driving in colder weather has no benefit other than heating you up inside the car. You’ll achieve the best fuel mileage and performance through usage. Idling the car in your driveway uses gas to go nowhere — essentially wasting money and fuel.
