Demystifying Engine Knock: What’s Really Happening Under Your Hood

December 28, 2023 by Denver Express Car Care

Some words and concepts may seem a bit mysterious, until you experience them for yourself.

Like the concept of engine knock. Drivers refer to it frequently, but what does it really mean? How will you know if you experience it? How concerned should you be?

Let’s start at the beginning.

What is engine knock?

Engine knock, also known as detonation or spark knock, is a phenomenon that occurs within an internal combustion engine.

Imagine the engine as a symphony of controlled explosions, where fuel and air mix in the combustion chamber to produce power. Now, imagine if this symphony were suddenly interrupted by an unruly drummer out of sync with the rest of the band – that’s engine knock.

When each engine cylinder has the correct balance of fuel and air, fuel burns in small controlled bursts and creates little shocks, igniting the next. If this doesn’t occur in rhythm, these bursts go off at the wrong time. The result? Engine knock.

What engine knock feels like

As a driver, you can take two approaches to driving: reactive or proactive. A reactive driver ignores everything until you can’t ignore it anymore. A proactive driver pays attention to every detail, noting when your car isn’t driving the way it should.

Demystifying Engine Knock: What's Really Happening Under Your Hood

A proactive driver is more likely to notice the signs of engine knock.

Engine knock is often first detected by the distinct sound it produces. It’s commonly described as a sharp, metallic “pinging” or “knocking” noise emanating from the engine bay. This noise may be more noticeable during acceleration or under load, such as when climbing hills or towing. In addition to audible cues, engine knock can manifest as vibrations or shakes felt through the steering wheel, floorboard, or even the entire vehicle. These vibrations are typically rhythmic and coincide with the detonation events happening within the engine.

Engine knock is often accompanied by a noticeable reduction in engine performance. You may experience a sluggish response to throttle inputs, a lack of power during acceleration, or a general feeling of the vehicle struggling to perform as expected. In severe cases, engine knock can produce unusual smells, such as the scent of burnt or overheated components. This may be an indication that the engine is working harder than usual, potentially causing increased wear and tear.

Modern vehicles are equipped with sophisticated onboard diagnostics; some may detect engine knock and trigger warning lights on the dashboard. If you see the “check engine” light or any other relevant warning lights, it’s essential to have your vehicle inspected promptly. Engine knock can contribute to increased temperatures within the engine. If you notice your temperature gauge rising more than usual, it could be a sign of detonation affecting the engine’s efficiency.

What causes engine knock?

Engine knock doesn’t happen out of the blue. Instead, it’s a slow decline caused by wear and tear. Every time you start the car, it impacts performance. Every road you move down affects the car in some way.

One of the primary causes of engine knock is using fuel with an octane rating lower than your engine requires. Octane rating indicates a fuel’s resistance to premature ignition. High-performance or turbocharged engines often demand higher octane fuel to prevent knock.

Advanced Ignition Timing

Ignition timing refers to the precise moment the spark plug ignites the air-fuel mixture. If the ignition timing is too advanced, meaning the spark occurs too early, it can increase pressure and temperature in the combustion chamber, causing knocking.

Excessive Engine Temperature

Overheating can be a catalyst for engine knock. High temperatures contribute to the formation of hotspots in the combustion chamber, promoting spontaneous ignition of the fuel-air mixture before the spark plug fires.

Carbon Deposits

Carbon deposits on the combustion chamber walls can act as hot spots, initiating combustion before the spark plug ignites. This is more common in engines with poor fuel quality or prolonged use of low-quality oils.

How engine knock affects a car over time

What’s that sound? Ignoring or neglecting the signs of engine knock can lead to progressively severe consequences. If you ignore the sound coming from your engine, the effects can be severe:

Piston and Cylinder Damage

Engine knock creates intense pressure waves within the combustion chamber, leading to forceful impacts on the piston and cylinder walls. Over time, these repeated impacts can cause accelerated wear and damage to these critical components.

Connecting Rod Wear

The connecting rods, which link the pistons to the crankshaft, are also vulnerable to the effects of engine knock. The forceful detonations can lead to increased stress on the connecting rods, potentially resulting in bending or other forms of damage.

Spark Plug and Ignition System Issues

Persistent engine knock can negatively impact the spark plugs and the entire ignition system. The excessive pressure and heat generated during detonation can cause premature wear on spark plug electrodes, leading to misfires and a further deterioration of engine performance.

Increased Heat and Friction

Engine knock contributes to higher temperatures within the combustion chamber. The increased heat, combined with friction from the forceful detonations, accelerates overall wear on engine components. This can lead to a reduction in engine efficiency and an increased likelihood of component failure.

Reduced Fuel Efficiency

As engine knock compromises the efficient combustion of fuel and air, the engine has to work harder to maintain performance. This increased workload results in higher fuel consumption, leading to reduced overall fuel efficiency.

Catalytic Converter Damage

The heightened temperatures caused by engine knock can harm the catalytic converter. Over time, this may lead to a decline in efficiency and functionality, potentially triggering the illumination of the “check engine” light and necessitating costly repairs.

Engine Knock Feedback Loop

If left unaddressed, engine knock can create a feedback loop of damage. For example, damaged pistons and cylinders can lead to irregular combustion, further exacerbating engine knock and accelerating the wear and tear on various components.

Costly Repairs

The cumulative effects of engine knock can result in substantial and expensive repairs. Rebuilding or replacing damaged engine components, such as pistons, connecting rods, or the entire engine block, can be a significant financial burden.

Let’s Debunk Oil Change Myths

December 24, 2023 by Denver Express Car Care

I met a friend for lunch today. She couldn’t linger after the bill came; she had a long list of things to get done. Groceries. Run her son to soccer practice. The everyday chores we all have on a busy day. Then she turned, to-do list in hand, and said, “Oh yeah, I guess I have to get an oil change. I keep putting it off …”

Your car needs motor oil in the same way it needs gasoline. If you fail to fill the gas tank, your car won’t operate. If you forget to change the motor oil, your engine will eventually cease.

We can’t forget gas. Our cars will let us know pretty quickly. Motor oil takes a bit longer.

Maybe that’s why we tend to believe some of the myths around motor oil. Like if it’s really necessary to get an oil change every 3,000 to 5,000 miles. Is that true?

Let’s dive in and look at some of the most common oil change myths, and discover what you should do to protect your vehicle.

Oil change myth #1: An oil change is necessary every 3,000 miles

In the past, the 3,000-mile rule made sense when conventional oils and engine technology were less advanced. However, with modern vehicles and synthetic oils, this myth has become outdated and, more importantly, costly. Here’s the reality:

The Truth: Follow your vehicle manufacturer’s recommendations.

Modern vehicles are designed to run efficiently with longer intervals between oil changes. In fact, most car manufacturers and oil experts recommend changing the oil every 7,500 to 10,000 miles, and some high-performance synthetic oils can extend that interval even further. When in doubt, refer to your manufacturer’s guidance and check your owner’s manual for more details.

Oil change myth #2: Change your oil before a road trip

It’s a well-intentioned belief—many drivers think that changing their oil before a road trip is a precautionary measure to ensure their vehicle performs optimally during long journeys. However, in most cases, this belief is more rooted in tradition than practicality.

The Truth: Timing is key, not just mileage.

While regular oil changes are crucial for maintaining a healthy engine, changing the oil right before a road trip may not be necessary if you’ve recently had a scheduled maintenance service. What matters most is the timing of your last oil change relative to your vehicle’s recommended intervals.

Oil change myth #3: The oil filter should be replaced at every oil change

For years, many drivers have thought that changing the oil filter with every oil change is a non-negotiable practice. However, the truth lies in understanding the purpose of the oil filter and how it functions within the context of regular vehicle maintenance.

The Truth: Oil filters have a lifespan.

Oil filters are crucial in trapping contaminants and debris, preventing them from circulating through the engine and causing damage. While they are effective, it’s important to recognize that most modern oil filters are designed to last longer than a single oil change interval.

Just like oil change intervals, automobile manufacturers provide guidelines for oil filter replacement in the owner’s manual. These guidelines are often tied to specific mileage or time intervals. High-quality oil filters, especially those designed for extended use, can efficiently capture and retain contaminants over an extended period. Choosing a reputable brand and type of oil filter can contribute to longer service intervals. Trust a reliable mechanic to help you along.

Oil change myth #4: Only use one type of oil forever

Many drivers have grown up with the belief that once you find the right oil for your vehicle, you should stick with it indefinitely. However, advancements in engine technology and the availability of various oil formulations challenge this long-standing belief.

The Truth: Adaptability to changing needs.

Modern engines are designed to be more versatile and can often accommodate different types of oils depending on driving conditions, climate, and the engine’s age. While it’s crucial to choose an oil that aligns with your vehicle’s requirements, exclusive loyalty to a single type may not be necessary.

There are different types of oils, including conventional, synthetic, and blends. Each type has its own set of advantages and is formulated to address specific needs. For instance, synthetic oils offer superior high-temperature stability and overall engine protection. Check your vehicle’s owner’s manual for the manufacturer’s recommended oil specifications. Many modern engines can benefit from various oil formulations, allowing you to adapt to changing driving conditions and seasons. If you frequently experience extreme temperatures, stop-and-go traffic, or engage in heavy towing, you may need an oil formulation that offers enhanced protection under these specific conditions.

Oil change myth #5: Thicker oil is always better

Many car owners have been led to believe that using thicker oil will enhance their engine’s protection, especially in older or high-mileage vehicles. However, the truth lies in understanding the delicate balance between oil viscosity and engine specifications.

The Truth: Optimal viscosity for engine health.

While oil viscosity is a critical factor in engine protection, the belief that thicker oil is universally superior is inaccurate. The optimal viscosity depends on various factors, including the vehicle’s design, engine specifications, and operating conditions. Thicker oils may be beneficial in extreme temperatures, providing better lubrication in high-temperature conditions. However, using excessively thick oil in moderate climates can hinder engine efficiency and fuel economy.

Oil change myth #6: Synthetic oil leaks more

For years, some car owners have been hesitant to make the switch to synthetic oil due to the fear that it might cause an increase in leaks. However, this myth is rooted more in misinformation than actual evidence.

The Truth: Synthetic oils and engine seals.

Synthetic oils, known for their superior lubrication properties and stability, are designed to meet or exceed the specifications set by vehicle manufacturers. The misconception about increased leaks likely arises from misunderstanding the relationship between synthetic oils and engine seals. High-quality synthetic oils are formulated to be fully compatible with engine seals and gaskets. In fact, many synthetic oils contain additives that can condition and rejuvenate seals, reducing the risk of leaks. Synthetic oils offer enhanced stability at high temperatures, reducing the likelihood of oil breakdown and the formation of deposits that can contribute to leaks.

Oil change myth #7: Once you switch to synthetic oil, you have to stick with it

For many car owners, transitioning from conventional to synthetic oil comes with a perceived permanence. However, this myth limits flexibility and doesn’t consider the evolving needs of both your vehicle and advancements in lubrication technology.

The Truth: Fluid compatibility and gradual transitions.

Switching between oil types, including returning to conventional oil after using synthetic, is generally acceptable and won’t harm your engine. Both traditional and synthetic oils are compatible with each other, and modern engines are designed to handle different oil formulations. Modern engines are built to hold various oil formulations. If your vehicle initially used conventional oil and you switch to synthetic, or vice versa, the engine should adapt without negative consequences. Check with your owner’s manual for more details.

Are Additives In Motor Oil Important?

December 21, 2023 by Denver Express Car Care

You know car maintenance is important. Some projects easily filter into your to-do list – you no longer have to think about them.

Like stopping for gas. Or ensuring your tires are properly pressurized.

Or changing the motor oil.

Most of us stop for an oil change when the little sticker in the window tells us we’ve reached a specific mileage. But have you ever stopped to think about why? Or what’s in motor oil that makes it beneficial for your vehicle? (Yes, motor oil additives are essential!)

Let’s dig in!

This is why your car needs motor oil

Motor oil is also referred to frequently as engine oil. It’s a lubricant used in internal combustion engines to reduce friction and wear between moving parts.

It’s designed to lubricate the engine components, such as the pistons, bearings, and camshaft, to ensure smooth operation and minimize friction-related heat. It also helps:

Dissipate heat generated during engine operation, preventing components from overheating.
Keep the engine clean by carrying away contaminants and deposits, preventing sludge build-up and maintaining engine cleanliness.
Form a film between the moving parts, helping to create a seal and prevent leaks.
Provides a protective layer to prevent corrosion of engine components.

Now imagine what would happen if you didn’t add motor oil regularly.

Every part would be impacted. The friction and wear would occur gradually over time as each part moved a little slower, and didn’t work quite as designed.

More friction means more heat. If you drive a lot and this continues, heat may build and lead to overheating. And that can bring a lot of problems inside the engine compartment.

This doesn’t happen quickly. Instead, it’s a slow build-up of sludge, dirt, and debris, gradually contaminating the motor oil and negatively impacting the engine. Which leads to poor fuel efficiency, increased emissions, more costly repairs, and eventual engine failure.

Whew!

All from not paying attention to your motor oil. Who knew a little can of motor oil could do so much for your car.

What’s in a can of motor oil?

Here’s where it gets interesting. Motor oil is more than just another liquid.

New, clean motor oil is typically amber or light brown. However, as it ages and accumulates contaminants, it can darken and appear black. The color can also be influenced by the additives and base oil used in the formulation. High-quality synthetic oils may have a clearer, lighter color.

You may notice its mild, characteristic petroleum odor. However, as oil ages and accumulates contaminants, it may develop a stronger, more unpleasant smell. The presence of burnt or acrid odors could indicate overheating or other issues within the engine.

Motor oil is designed to have a specific viscosity, which is a measure of its thickness or resistance to flow. It’s often labeled with two numbers, such as 10W-30. The first indicates the oil’s viscosity at low temperatures, while the second indicates the viscosity at high temperatures. The consistency can range from relatively thin to more viscous, depending on the oil’s intended use and operating conditions.

What’s in motor oil? It can vary depending on the specific formulation, brand, and intended use (conventional, synthetic, or a blend). However, motor oil typically consists of a base oil and additives. Here’s what’s in each:

Base Oil

The base oil is the primary component of motor oil and makes up the majority of its volume. It can be derived from crude oil or synthesized chemically. The base oil provides the lubricating properties necessary to reduce friction and wear between moving engine parts. The quality and type of base oil (conventional, synthetic, or semi-synthetic) significantly influence the performance of the motor oil.

Additives

Motor oil contains various additives to enhance its performance and provide additional benefits. These additives include:

Detergents and Dispersants – These additives help keep the engine clean by preventing the formation of deposits and sludge. They disperse and suspend contaminants, allowing them to be carried away during oil changes.
Anti-Wear Agents – These additives form a protective film on metal surfaces, reducing friction and minimizing wear on engine components.
Viscosity Index Improvers – These additives help stabilize the viscosity of the oil over a range of temperatures. This ensures that the oil maintains its effectiveness in lubricating the engine under different operating conditions.
Antioxidants – These additives help prevent the oil from oxidizing and breaking down, extending the oil’s life and maintaining its properties over time.
Corrosion Inhibitors – These additives protect engine components from corrosion by forming a protective layer on metal surfaces.
Foam Inhibitors – These additives help prevent the formation of foam, ensuring efficient lubrication and preventing air entrainment in the oil.
Pour Point Depressants – These additives improve the low-temperature flow characteristics of the oil, preventing it from thickening in cold conditions.
Friction Modifiers – These additives reduce friction between moving parts, improving fuel efficiency.

Why your car needs motor oil additives

With everything we do and have in our world today, we can look back over time and see how it’s a little better than in the past. We learn. We grow. And we make things better.

Motor oil has had that progression, too.

Go back to the very first cars and motor oil was a base ingredient with little in it. Over time, we’ve learned to add things that make it better – better for your car, better for the environment, better for efficiency.

Today’s motor oil additives are essential team players dedicated to keeping your car’s engine in top shape. These additives each contribute unique benefits.

Take the detergent and dispersant combo, for instance. They actively prevent the accumulation of deposits and sludge, maintaining the engine’s cleanliness. What was once difficult or even impossible, today is handled through additives within the motor oil itself.

Then there’s the anti-wear agent, a vital component forming a protective layer on metal surfaces, minimizing friction and preventing premature wear on critical engine parts. That’s just one reason the average age of a car on the road is creeping upwards every year.

Yes, additives are a good thing. Your car’s engine can’t survive without motor oil. But increasingly, it can’t function well over time without motor oil additives.

While you might not have a deep understanding of motor oil and its job, hopefully, this provides you with a little more information about its importance.

Changing motor oil regularly is essential to the health of your vehicle.

We can help you with that.

It’s the best way to ensure a longer, healthier life for your engine.

How Do You Know You’re Choosing the Right Oil Change Service?

December 7, 2023 by Denver Express Car Care

Changing your car’s oil is a foundational part of routine maintenance. Oil protects your engine from wear and tear by minimizing friction as you drive. Over time, oil collects dirt and grime and becomes too dirty to lubricate an engine’s various parts. Heat builds up. Parts wear down. And if not corrected, can lead to total engine failure.

But there’s an easy way to prevent all that: relying on an oil change service to do the job correctly the first time. Many oil change service shops design their oil changes to be as simple as possible – drop off your car and pick it up a short while later. Keep in mind that not all oil changes are created equal.

Some shops prefer the in-and-out method. They provide based services like replacing the oil and filters as needed.

Other shops use this as an opportunity to look at other parts that may be impacting your drive. This can alert you to potential problems before they escalate.

Of course, if you want a full service oil change, it’s important to go with a service you can trust. Will they provide you with a realistic look at how well your car is operating? Or are they just trying to grow their profits?

How Do You Know You’re Choosing the Right Oil Change Service?

What to look for in a full service oil change

Many auto repair shops advertise complimentary services with an oil change. For you, it’s a good place to start when trying to find a shop you can rely on for bigger jobs in the future.

Yes, a competitive price is important. But you should look beyond that to the services they provide. There can be a vast difference between shops; they may charge you more after your car is in and being serviced.

You should also pay attention to the technicians. Do they hire experts? Are staff members friendly and approachable? Do they take the time to explain the services being performed on your car? Or are they more get-you-in-and-get-you out?

Do they leave an impression and make you want to do business there again?

Full service provides an array of services

Many oil change services provide oil and filters. They consider the rest of the car someone else’s responsibility.

Full service oil changes provide more complimentary services. Such as:

Draining and refilling with motor oil
New oil filter
Lubrication if needed
Inspect and top off all fluids, including transmission fluid, antifreeze, windshield washer fluid, battery water, and differential fluid
Tire air-pressure check
Engine light check

If there’s a problem, the technician will alert you to the fact, provide options, and ensure your car is safe and ready to drive once again.

Why regular maintenance is essential to your car’s longevity

Your car may seem like it’s always ready for the next drive … until it isn’t. Just like us humans need regular check-ups to stay in tip-top shape, your four-wheeled friend needs some love, too.

Regular maintenance keeps everything running smoothly, prevents minor issues from turning into big, wallet-draining disasters, and ensures you’re not stranded on the roadside with a smoking engine.

Think about it as an investment in your car’s longevity and your peace of mind. Oil changes, tire rotations, brake checks – they may seem small, but they add up to a reliable and efficient ride.

Plus, staying on top of maintenance can actually save you money in the long run by nipping potential problems in the bud before they snowball into major repairs. Saving you money and ensuring many more miles of smooth cruising.

What is an oil and filter change?

An oil and filter change is like a spa day for your car’s engine. Imagine your car’s engine is the heart of the operation, and oil is its lifeblood. Over time, as you rev up and roll on down the road, that oil gets dirty and loses its effectiveness. That’s where the oil change is necessary.

During an oil change, the old, worn-out oil is drained from the engine, making room for a fresh batch. And it’s not just about the oil – the oil filter gets swapped out, too. The oil filter is designed to keep out dirt and debris that could cause trouble. As it does its job, it clogs, so replacing it is key to maintaining a healthy engine.

This tag team of fresh oil and a new filter ensures your engine stays lubricated and cool, running like a well-oiled machine – literally! It’s a relatively quick and straightforward procedure, but oh, does it make a difference in keeping your car’s engine humming happily along. It truly is one of the easiest ways to keep your car running.

How often should oil be changed?

If you do any searching, you’ll discover this is a heavily debated question!

The frequency of oil changes depends on a few factors, like the type of oil you use, your driving habits, and the manufacturer’s recommendations. As a general rule of thumb, many experts suggest getting an oil change every 3,000 to 5,000 miles. However, it’s always a good idea to consult your car’s manual because it holds the ultimate wisdom about your specific vehicle.

If you’re using synthetic oil, you might be able to stretch that interval a bit, as synthetic oils tend to last longer. Some modern vehicles equipped with advanced engine technology and synthetic oils can go 7,500 miles or more between changes.

If you’re a frequent road tripper, stop-and-go city driver, or you tow heavy loads, you might want to err on the side of caution and stick to the lower end of the mileage spectrum. The key is to stay mindful of your driving conditions and the type of oil your car drinks – it’s all about keeping that engine purring contentedly for miles to come!

Not quite sure? That’s where it helps to have a trusted technician on your side. They can help you set up an oil changing plan that works for your lifestyle and the way you drive.

Isn’t that what an auto repair shop should do – be your trusted advisor to keep your car going for as long as you own your car.

That’s what we strive for. That’s our goal for every customer who brings their vehicle in for servicing.

Is Your Car Battery Charged and Ready For Winter?

December 3, 2023 by Denver Express Car Care

10. 9. 8. The temperatures across the Front Range are getting colder.

Do you know if your car battery is charged and ready for the winter?

It’s no secret that Colorado has wild weather all year long, especially in the winter. You can drive to work in sunshine with the windows down, and leave with a full-blown blizzard and arctic temperatures that create dangerous situations.

Yet driving isn’t the only hazardous thing you might incur. If you haven’t checked your car battery in a while, it might not start when you need it. And as the sun sets and the winds blow colder, that can be an uncomfortable situation.

Maybe now is the time to ensure your car battery is working at its best.

How a basic car battery functions

A car battery is like the heart of your vehicle’s electrical system. It works by storing electrical energy in a chemical form and then releasing it when you need to start the engine and power various electrical systems in your car.

This magic happens through a lead-acid battery, the standard in most cars. A car battery has two lead plates soaked in sulfuric acid. One plate is made of lead dioxide, and the other is lead. When the battery charges, it goes through a chemical reaction, converting the lead dioxide into lead sulfate and releasing electrical energy, creating a voltage difference between the two plates.

Is Your Car Battery Charged and Ready For Winter?

When you turn your ignition key, your car battery springs into action, sending an electric current to the starter motor. This motor cranks the engine to life. This initial power surge is a significant jolt for the battery, and it needs to be in good shape to do it effectively.

But the battery’s job doesn’t end there; it also provides power to various electrical systems like the lights, radio, air conditioning, and power windows when the engine isn’t running. The alternator, another part of the car’s electrical system, takes over while the engine is running, charging the battery and keeping all those electrical systems humming.

As you use your car and its electrical components, the battery gets depleted, which can affect its efficiency. The recharging process happens while you’re driving, thanks to the alternator. That’s why it’s important to keep an eye on the battery’s condition, maintain clean terminals, and ensure it’s adequately charged.

How cold and hot weather affect a car battery

Batteries operate well in average weather conditions. However, Colorado has anything but average weather conditions. Remember how we talked about temperature extremes a few paragraphs ago? That weather can play tricks on your car battery.

When the temperature drops, your battery’s performance can take a nosedive. The cold slows down the chemical reactions happening inside your battery, making it less effective at delivering power. It’s like the battery goes into hibernation mode. As a result, your battery loses some of its juice, and starting your car can become a real struggle.

In extremely cold conditions, the engine oil thickens, which, combined with the reduced battery capacity, makes starting your car an uphill battle. Sometimes, it might not start at all. Plus, frequent cold exposure can take a toll on your battery’s overall lifespan.

It’s not just cold weather that can take its toll. When the temperature soars, your battery isn’t in its happy place either. High temperatures cause your battery to self-discharge faster, meaning it loses its charge more quickly, even when your engine is taking a break. The heat can also speed up a not-so-friendly process called sulfation, where lead sulfate crystals build up on your battery’s plates, reducing its capacity and lifespan over time.

Excessive heat can also shorten your battery’s lifespan. It can cause some serious, sometimes permanent, damage that might mean an early retirement for your battery. In scorching weather, your battery’s electrolyte (the acid solution inside) can evaporate, leading to reduced electrolyte levels and potential overheating.

Most batteries come with a three to seven-year life, depending on the battery you install. It works hard day after day, taking the abuse the weather dishes out. (Yes, there are other impacts. The weather plays a significant role.)

Preventative car battery maintenance as we head into winter

Now that we’ve covered how the weather can mess with your car battery, let’s talk about what you can do to keep it in good shape, especially as we’re heading into the winter months.

First off, it’s a great idea to give your battery a little love before winter sets in. Start by doing a visual inspection. Check for any signs of corrosion or damage on the battery terminals and cables. If you see any gunk or buildup on the terminals, clean them up using a mixture of baking soda and water and a wire brush. This helps ensure a good electrical connection and keeps your battery humming.

Next, have a professional do a battery load test. They’ll check how well your battery holds a charge. If it’s not up to snuff, it might be time to consider a replacement. After all, you don’t want to be left out in the cold with a dead battery when you’re trying to start your car on a chilly morning.

During winter, every bit of power counts. So, if your battery’s on the older side, it’s worth thinking about a replacement before it gives up on you in the cold. Newer batteries tend to perform better in low temperatures, and have less chance of breaking down.

While Colorado isn’t a hub of arctic weather, you might choose to consider where your car is parked at night. Living in the foothills is different from living downtown. Having a garage provides more warmth and protection than if your car resides in a parking lot. If your car lives in frosty conditions, consider using a battery warmer or insulator. These handy devices can help keep your battery’s temperature up a bit, so it’s more willing to cooperate when you turn the key.

Finally, keep in mind that batteries need to be recharged regularly. Usually, this happens by using your car for your daily drive. If it sits in the garage most days, rarely used, a battery maintainer (or a trickle charger) is a great investment. It keeps your battery topped off and ready to roll, even if you rarely drive your car.

Is your car battery ready for winter?

A little preventative maintenance before winter can go a long way in ensuring your car battery behaves when you need it most. If you haven’t thought about your car battery yet this fall, maybe now is the time.

Give it a little TLC yourself. Or stop by, and we’ll test it out here. Either way, your battery will thank you when those frosty mornings roll around!
