Now that winter is upon us, a common question pops up among many drivers: "How long should I warm up my car before driving when it’s cold out?" This topic is especially important for those of us bracing for frosty mornings. Let's dive into some straightforward and helpful advice to keep your car running smoothly in cold weather.
The answer depends on whether your car is a newer or older model, and it all comes down to the type of engine it has.
Every car is different, and the year when car makers switched from carburetors to fuel injection can vary. A good rule of thumb is that cars from the early 1990s onwards are more likely to have fuel-injected engines. But the best way to know for sure is to check your car's manual. The manual will tell you exactly what your car needs to stay happy and healthy.
Diesel engines are a bit different when it comes to winter weather, so let's break it down in simple terms.
If you're driving an EV, you'll find it's a bit different from cars with regular engines when it comes to getting ready in the cold.
One cool thing about electric cars is that they don't need time to warm up like traditional cars do. Since they don't have the usual engine parts, you don't have to wait for engine oil to heat up. You can just start your EV and get going, even on those frosty mornings.
The big thing to watch in cold weather is your EV's battery. When it's cold, the battery might not work as well and your car won't go as far on a charge. But don't worry, you don't need to warm up the battery the old-fashioned way.
Many electric cars have a handy feature called "preconditioning." You can turn this on with your car's screen or a smartphone app. It warms up the battery while your car is still plugged in. This keeps your battery ready to go and helps it last longer on the road.
Want to hop into a warm car? You can use preconditioning for that too! Doing this while your car is still charging is great because it uses electricity from your house, not your car's battery. That way, you save your battery for driving.
Just like with any vehicle, driving gently when you start out is a good idea. This doesn't exactly warm up your car, but it does help your battery and car parts work better in the cold.
Remember, each EV is a bit different. It's a great idea to read your EV's manual for the best tips on handling the cold. The manual will have all the details you need for your specific car.
In short, electric cars are pretty easy to get going in winter. You don't need to warm them up like other cars, but taking care of your battery and cabin can make your cold-weather drives more efficient and comfy!
Let's talk about why idling your car for too long in the winter isn't a great idea. We know it's tempting to keep the car running to stay warm, but this could be hard on your car. Here's what can happen:
When your car just sits there running, the engine doesn't get fully warm. This means the fuel doesn't burn completely and can mix with the engine oil. This mix, called oil dilution, makes the oil less effective and can wear out your engine faster.
Your engine likes to run at a certain temperature. If it's idling and not getting warm enough, parts inside the engine don't work as they should. This can cause more wear and tear on things like cylinder liners and piston rings.
Letting your car idle puts pressure on your battery and alternator because they don't get the chance to fully charge like when you're driving. Over time, this can lead to battery and alternator problems.
If the fuel isn't burning all the way, it can leave behind gunk on your spark plugs. This can cause your car to misfire, reduce how well it runs, and even make it hard to start.
If your engine isn't hot enough, the water in the exhaust can turn into condensation and cause rust and corrosion in your exhaust system.
Cars make less pollution when they're warm. If your car is idling and not fully warm, it can put out more harmful stuff into the air.
Idling means your car is using gas but not going anywhere. That's like getting zero miles per gallon!
To avoid these problems, you don't need to idle your car for long. Just a short time, enough to get the oil moving (about 30 seconds to a minute), is all you need before you start driving. And remember, driving gently at first helps your car warm up better than just sitting there.
Individual Car Needs: Every car is unique. Your vehicle’s manual is the best source of information on how to care for it, including specifics about warming up in winter.
Warming up your car properly during winter is crucial for its health and your comfort. Remember, these guidelines are primarily for modern, fuel-injected vehicles. For specific advice, especially for older or unique models, always refer to your vehicle's manual or consult with your local Kunes Auto Group Service Center.
Stay warm and drive safely!
