Why Should You Let Your Car Warm Up Before Driving?
Warming up your car before driving is important for several reasons. Firstly, when you initially start the engine, oil is moved across all necessary components of your car, acting as a lubricant to prevent destructive metal-to-metal rubbing.
In cold temperatures, parts of your engine can contract. Allowing your car to warm up allows the engine's components to disperse oil evenly throughout every moving part, preventing undue wear and tear.
In the past, warming up the car made sense when vehicles had carburetors, as it could take several minutes for the right blend of air and fuel to be delivered to the engine. However, modern fuel-injected engines have sensors that ensure the engine gets the perfect mixture of fuel and air, no matter how cold the winter morning.
How long should you let your car warm up before driving?
The recommended warm-up time for your car is no more than 30 seconds, especially on freezing-cold days, according to automotive expert Margarette Stine. This short warm-up period ensures proper oil circulation and lubrication of the engine. The U.S. Department of Energy also agrees, stating that most car manufacturers advise that your vehicle is ready to drive after just 30 seconds of warming up.
There is a campaign to reduce vehicle emissions by eliminating engine idling time, with the potential to remove the equivalent of 1.6 million cars from the road. The Environmental Protection Agency (EPA) suggests that idling should be limited to no more than 30 seconds, after which you should start driving your car.
