As temperatures drop, many drivers may wonder if they should let their car warm up before hitting the road. While it might seem like a good idea, the reality is much more complex. Can letting your car warm up before driving do more damage to your vehicle than you realize? In this blog, we’ll discuss whether warming up your car is beneficial, especially as cold weather approaches, and what laws you should be aware of if you live in Utah.
The Myth About Letting Your Car Warm Up
There is a long-standing belief that letting your car warm up before driving helps it run smoother, especially as cold weather comes to town. This belief stems from a time when vehicles used carburetors, which did indeed need warming up to function properly. However, more modern vehicles are designed with fuel injection systems that adjust automatically to temperature changes, making lengthy warm-up times unnecessary.
In most cases, your car’s engine will only need 30 seconds to a minute to warm up before it is safe to drive. In addition to requiring minimal warm-up time, driving your vehicle is actually a better way to warm up the engine because it gets the oil circulating faster, providing proper lubrication to the engine parts.
However, this is only possible if you are performing necessary maintenance on your vehicle. Before winter weather rolls into town, it is best to schedule an oil change and any other required maintenance and repairs for your car. Not only will this ensure it runs well when the temperature drops below zero, but it also ensures you have a safe vehicle to carry you throughout the season.
The Harm of Extended Idling
Letting your car warm up for extended periods can lead to unnecessary and avoidable wear and tear on your engine. This is especially true in cold weather, as idling does not warm up the transmission, tires, or other essential components that also need to be at optimal temperatures for smooth operation.
Letting your car warm up for extended periods also burns fuel inefficiently, leading to higher costs at the pump. More importantly, it can contribute to environmental pollution, emitting more greenhouse gases into the atmosphere than necessary. If you are concerned about your gas bill or carbon footprint, it is best to avoid letting your car warm up this winter.
What About During Extreme Cold?
It is reasonable to give your vehicle a few extra moments to warm up in extremely cold temperatures or anything below freezing. But again, while you might want to let your car warm up, driving slowly and gently at the start is a more effective way to warm up all of your car’s components. Make sure to clear ice and snow from the windshield and mirrors, but don’t rely on idling to do this for you. Once this snow and ice is removed, it is safe to begin driving.
Utah’s Idling Laws
If you live in Utah, being aware of local idling laws is important. Utah has specific regulations in place to limit vehicle idling as part of a long-standing effort to reduce air pollution. In many cities and counties, including Salt Lake City, Ogden, and Logan, vehicles are prohibited from idling for more than two minutes.
Violating Utah’s idling laws can result in a warning, a fine of up to $750, or up to 90 days in jail, depending on where you are. The state enforces these rules to help reduce emissions that contribute to air pollution, which is a serious issue in the winter months due to temperature inversions. If you are used to letting your car warm up for long periods, it is best to rethink this warm-up routine.
Best Practice for Cold Weather Driving
If you have to drive your vehicle when the temperature is below freezing, there are a few things you should remember to do. These include:
- Limit Idle Time: When starting your car, it is best to give it about 30 seconds to a minute to warm up and then drive slowly. Your vehicle will heat up faster while in motion.
- Use a Block Heater: If you live in an area with extremely cold winter weather, you should consider using a block heater to help your car warm up. This reduces the need for idling and makes starting your vehicle easier.
- Keep Your Vehicle Maintained: Make sure your battery, fluids, and tires are winter-ready. A well-maintained vehicle will be less affected by cold starts.
Protecting Your Vehicle All Year Long
While you may be tempted to let your car warm up before driving on a chilly morning, it is usually an unnecessary extra step for modern vehicles. Short idling times are sufficient, and driving gently is the most effective way to warm up your car. By following best practices and complying with Utah’s idling laws, you can save on fuel, protect your engine, and contribute to cleaner air.
