How Often Should a Car Be Driven? US Driver Guide

Determining how often should a car be driven involves several factors that every driver in the US should consider. Car batteries, for instance, require regular use to maintain their charge, typically needing a drive at least once a week, depending on the vehicle’s age and battery type. Short trips, specifically those less than 20 minutes, might not fully recharge the battery and can lead to a faster degradation of engine components. The American Automobile Association (AAA) recommends regular maintenance checks that include tire pressure and fluid levels, which can be affected by infrequent use. Location also plays a crucial role; coastal areas with high humidity can accelerate corrosion in cars that sit idle for extended periods.

The Silent Threat: Why Infrequent Drives Can Wreak Havoc on Your Car

It might seem counterintuitive, but leaving your car parked for extended periods can often be more detrimental than using it regularly. This isn’t just about dust accumulating on the hood; it’s about the gradual deterioration of essential components that keep your vehicle running smoothly.

The Perils of Prolonged Parking

Cars are designed to be driven. Regular use ensures that fluids circulate, parts remain lubricated, and the battery stays charged. When a car sits idle, these processes come to a standstill, leading to a cascade of potential problems.

Key Systems at Risk

Several key systems are particularly vulnerable to the effects of inactivity:

• Battery: Car batteries naturally discharge over time. When a car isn’t driven, the battery can drain completely, potentially shortening its lifespan and leaving you stranded.

• Tires: Tires can develop flat spots when they remain in the same position for weeks or months. They also lose pressure gradually, affecting handling and fuel efficiency.

• Engine: Engine oil can degrade and settle, leaving critical parts unprotected. Moisture can also accumulate inside the engine, leading to corrosion.

• Fuel System: Fuel can degrade and become stale, leading to clogged fuel lines and injector problems. This can result in rough running or even prevent the car from starting.

Why Proactive Care Matters

Ignoring these potential issues can lead to costly repairs down the road. Replacing a battery, tires, or even an engine can be a significant expense.

By taking a few simple proactive steps, you can mitigate these risks and ensure that your car remains in good condition, even when it’s not being driven regularly. Think of it as an investment in your vehicle’s long-term health and your peace of mind. The following sections will delve into practical strategies for protecting each of these vulnerable systems.

Battery Preservation: Keeping the Power Alive

The heart of your car’s electrical system, the battery, is often the first casualty of prolonged inactivity. But why does a battery drain when the car isn’t being used? Even when switched off, modern vehicles have a parasitic draw – a small but constant drain from systems like the alarm, the clock, and various electronic control units. Over weeks or months, this can deplete the battery to the point where it can no longer start the engine.

Fortunately, there are proactive steps you can take to keep your battery healthy and ready to go. Here, we’ll explore two effective strategies: using a battery tender and disconnecting the battery entirely. Each approach has its own set of benefits and drawbacks.

Option 1: Embracing the Battery Tender/Maintainer

A battery tender, also known as a battery maintainer, is a smart device designed to deliver a low, consistent charge to your battery. It essentially "trickle-feeds" the battery, replenishing the energy lost to parasitic draw and preventing sulfation (the formation of lead sulfate crystals that reduce battery capacity).

How a Battery Tender Works

Unlike a battery charger that’s meant to rapidly recharge a depleted battery, a tender focuses on maintaining an optimal charge level. It monitors the battery’s voltage and automatically adjusts the charging current as needed, preventing overcharging and potential damage. Battery tenders are a hands-off approach for longer term battery maintenance.

Connecting and Using a Battery Tender: A Step-by-Step Guide

Connecting a battery tender is a straightforward process:

1. Safety First: Wear safety glasses and gloves. Work in a well-ventilated area.
2. Identify Terminals: Locate the positive (+) and negative (-) terminals on your battery.
3. Connect Clamps: Attach the red clamp of the battery tender to the positive terminal and the black clamp to the negative terminal. Make sure the connections are secure.
4. Plug In: Plug the battery tender into a standard electrical outlet.
5. Monitor: Most tenders have indicator lights that show the charging status. Once fully charged, the tender will switch to maintenance mode.

Important Safety Precautions:

• Always read and follow the manufacturer’s instructions for your specific battery tender.
• Ensure the tender is compatible with your battery type (e.g., lead-acid, AGM, lithium-ion).
• Never use a battery tender in an enclosed space with flammable materials.

Option 2: Disconnecting the Battery: A More Drastic Measure

Disconnecting the battery is a more direct way to prevent drain. By physically severing the connection, you eliminate the parasitic draw altogether.

Safely Disconnecting Your Battery

1. Safety First (Again): Wear safety glasses and gloves. Ensure the engine is off and the keys are removed from the ignition.
2. Locate Terminals: Find the positive (+) and negative (-) terminals on your battery.
3. Disconnect Negative First: Use a wrench to loosen the nut on the negative (-) terminal clamp. Carefully remove the clamp and tuck it away from the terminal to prevent accidental contact.
4. Disconnect Positive: Repeat the process for the positive (+) terminal.
5. Secure the Cables: Secure both disconnected cables to prevent them from accidentally touching the battery terminals or any metal parts of the car.

Potential Drawbacks and Considerations:

While effective, disconnecting the battery has some potential downsides.

• Loss of Electronic Settings: You may lose stored settings for your radio, navigation system, seat preferences, and other electronic features.
• Alarm System Issues: Disconnecting the battery can trigger the alarm system on some vehicles. Consult your owner’s manual for specific instructions on how to disable the alarm before disconnecting the battery.
• Computer Reset: Modern cars rely heavily on their onboard computers. Disconnecting the battery can reset these computers, which may affect the car’s performance for a short period after reconnection until the system relearns optimal settings.

Choosing the right battery preservation strategy depends on your specific needs and circumstances. A battery tender offers a convenient, hands-off approach for maintaining optimal charge levels. Disconnecting the battery is a more drastic measure, but it can be effective if you’re storing your car for an extended period and are willing to accept the potential drawbacks.

Tire Care: Preventing Flat Spots and Maintaining Pressure

From the engine to the aesthetics, there are many things that can be impacted by a vehicle sitting idle. Another crucial aspect often overlooked is the well-being of your tires.

Left unattended, tires can suffer from flat spots and gradual pressure loss, compromising ride quality and even safety. Let’s explore effective strategies to combat these issues and keep your tires in optimal condition during periods of inactivity.

The Enemy: Flat Spots and Pressure Loss

When a vehicle sits for an extended period, the weight of the car presses down on a specific area of the tire. This prolonged pressure can cause the tire to develop a flat spot, a deformation in the tire’s shape that results in an uneven ride until the tire warms up and regains its roundness (sometimes, it becomes irreversible).

Compounding this, tires naturally lose air pressure over time. Temperature fluctuations exacerbate this, as colder temperatures cause air to contract, further decreasing tire pressure.

Underinflated tires are more susceptible to flat spotting and can also negatively impact fuel efficiency and tire wear.

Solution 1: Strategic Overinflation

A straightforward way to minimize flat spotting and pressure loss is to inflate your tires to the maximum pressure recommended by the tire manufacturer.

This information is typically found on the tire sidewall.

How to Overinflate Correctly

• Locate the Maximum Pressure: Identify the maximum pressure listed on the tire sidewall. Do not exceed this pressure.

• Inflate the Tires: Using a reliable tire pressure gauge and an air compressor, inflate each tire to the maximum recommended pressure.

• Regular Monitoring is Key: Check and adjust the tire pressure regularly, especially with changes in ambient temperature. Remember that as temperatures drop, you’ll need to add air to maintain the desired pressure.

Important Note: While overinflation helps prevent flat spots, it’s crucial to return the tire pressure to the vehicle manufacturer’s recommended pressure (usually found on a sticker inside the driver’s side doorjamb) before driving.

Overinflating beyond the vehicle manufacturer’s recommendation for regular driving can lead to a harsher ride and uneven tire wear.

Solution 2: Tire Cradles and Periodic Movement

For long-term storage, consider using tire cradles. These specially designed ramps distribute the vehicle’s weight more evenly across the tire, reducing the risk of flat spotting.

Alternatively, simply moving the car periodically can achieve a similar effect.

Tire Cradles: Even Weight Distribution

Tire cradles are an investment that can pay off in the long run, especially if you store vehicles for extended periods. They work by providing a curved surface that supports more of the tire’s contact area.

This broader support distributes the vehicle’s weight, preventing excessive pressure on one specific point.

The Power of a Short Drive

Even a short drive, or simply rolling the car forward or backward a few feet every few weeks, can significantly reduce the risk of flat spots.

This minimal movement shifts the contact point between the tire and the ground, preventing prolonged pressure on a single area.

Remember to check and adjust tire pressure after moving the vehicle, as the tires may have lost some air.

Engine Health: The Importance of Oil and Lubrication

From the tires to the exterior, there are many things that can be affected when you leave your vehicle unattended for prolonged periods. However, one of the most critical considerations for preserving a car during periods of inactivity is the health of its engine oil.

Engine oil is the lifeblood of your vehicle’s engine, responsible for lubricating moving parts, dissipating heat, and preventing corrosion.

However, when a car sits idle, the engine oil can degrade, losing its vital lubricating properties. This can lead to significant engine damage when you finally decide to hit the road again.

Why Engine Oil Degradation Matters

Over time, engine oil can break down due to oxidation and contamination. Even if you’re not driving, the oil is still exposed to air and moisture, which can cause it to thicken and form sludge.

This sludge can clog oil passages, restrict oil flow, and ultimately lead to engine wear and tear. In other words, an apparently idle engine can still be suffering internal damage if its oil is neglected.

Therefore, it’s essential to take proactive steps to protect your engine while it’s not in use. There are two primary strategies to consider: changing the oil before storage and periodically starting the engine.

Solution 1: Changing the Oil Before Storage

One of the best things you can do to protect your engine is to change the oil before storing the car.

This replaces the old, potentially contaminated oil with fresh oil that contains detergents and additives to protect the engine’s internal components.

Using fresh oil provides a clean layer of protection against corrosion and sludge buildup during inactivity.

Choosing the Right Oil

When changing the oil, be sure to use the correct type of oil for your vehicle.

Consult your owner’s manual to determine the recommended oil viscosity and specification.

Consider using synthetic oil, which generally offers superior protection against degradation compared to conventional oil.

Also, remember that a quality oil filter goes hand-in-hand with fresh oil. Don’t skimp on this inexpensive safeguard.

Solution 2: Regular Engine Start-up (With Caution)

Another option is to start the engine periodically to circulate the oil and keep the internal components lubricated.

However, this approach is not without its risks and should be done with caution.

The debate around starting a car periodically hinges on whether the potential benefits outweigh the risks.

The Pros and Cons of Periodic Start-ups

The pros of starting the engine periodically include:

• Circulating fresh oil to coat engine components
• Preventing seals from drying out
• Recharging the battery (although a battery tender is a better solution).

The cons include:

• Potential for condensation buildup inside the engine if it’s not allowed to reach full operating temperature.
• Increased wear and tear on engine components during cold starts.
• Fuel consumption and emissions.

How to Start the Engine Properly

If you choose to start the engine periodically, it’s crucial to do it correctly.

• Allow the engine to reach full operating temperature: Run the engine for at least 15-20 minutes to ensure that it warms up completely and burns off any condensation.
• Avoid short bursts: Starting the engine for just a few minutes can actually do more harm than good, as it can lead to condensation buildup without providing adequate lubrication.
• Ensure adequate ventilation: Always start the engine in a well-ventilated area to prevent carbon monoxide poisoning.

Ultimately, whether you choose to change the oil before storage or start the engine periodically depends on your individual circumstances and risk tolerance.

However, by taking proactive steps to protect your engine oil, you can help ensure that your car remains in good condition, even when it’s not being driven.

Fuel System Preservation: Stabilizing Your Fuel

From the tires to the engine, taking care of different parts of the car is important when you leave your vehicle sitting idle for a while. But one of the most vital considerations for preserving a car during periods of inactivity is the health of its fuel system.

Fuel, seemingly inert, is actually a complex and volatile substance. Over time, fuel can degrade, leading to a host of problems within your vehicle’s fuel system. Neglecting this aspect can result in costly repairs and decreased engine performance when you finally decide to hit the road again.

The Silent Threat: Fuel Degradation and its Consequences

When a car sits idle, the gasoline in the tank begins to break down through a process called oxidation. This degradation can lead to several issues:

• Formation of Gum and Varnish: As fuel breaks down, it creates sticky residues that can clog fuel lines, injectors, and carburetors (in older vehicles). These deposits restrict fuel flow, leading to poor engine performance, reduced fuel efficiency, and even engine misfires.

• Water Absorption: Gasoline can absorb moisture from the air, especially in humid environments. Water in the fuel tank can cause corrosion, fuel line freezing in cold climates, and further degradation of the fuel itself.

• Octane Loss: Over time, fuel loses its octane rating, which is a measure of its resistance to knocking or pinging in the engine. Using low-octane fuel can damage the engine over time.

The Solution: Fuel Stabilizer – Your Fuel System’s Best Friend

Fortunately, there’s a simple and effective solution to combat fuel degradation: fuel stabilizer. Fuel stabilizer is an additive that helps to prevent fuel from breaking down, keeping your fuel system clean and protected during periods of inactivity.

How Fuel Stabilizer Works

Fuel stabilizer works by:

• Slowing down the oxidation process.
• Preventing the formation of gum and varnish.
• Protecting against water absorption.
• Stabilizing the octane rating of the fuel.

By using fuel stabilizer, you can ensure that your fuel remains fresh and your fuel system stays clean and protected, even when your car is not being driven.

Step-by-Step Guide: Adding Fuel Stabilizer to Your Fuel Tank

Adding fuel stabilizer is a quick and easy process. Here’s a step-by-step guide:

1. Gather Your Supplies: You’ll need a bottle of fuel stabilizer (choose a reputable brand and check its compatibility with your vehicle) and a funnel.

2. Determine the Dosage: Read the instructions on the fuel stabilizer bottle to determine the correct dosage for your fuel tank capacity. It’s crucial to use the correct amount – too little may not be effective, while too much could potentially harm the engine.

3. Add the Stabilizer to the Fuel Tank: Open your fuel tank cap and carefully pour the fuel stabilizer into the tank using a funnel.

4. Fill the Tank with Fresh Fuel: Add fresh fuel to the tank. Filling the tank almost completely helps minimize air space, reducing the potential for condensation and fuel degradation.

5. Run the Engine Briefly: As mentioned in the previous section about engine health, start the engine and let it run for a few minutes to circulate the stabilized fuel throughout the fuel system. This ensures that the fuel stabilizer reaches the fuel lines, injectors, and other components.

Important Considerations

• Always follow the manufacturer’s instructions for both the fuel stabilizer and your vehicle.
• Use a fuel stabilizer specifically designed for gasoline engines (or diesel engines, if applicable).
• If you are storing your car for an extended period (e.g., several months or years), consider adding a slightly higher concentration of fuel stabilizer than recommended (refer to the product instructions).
• Dispose of any leftover fuel stabilizer properly, following local regulations.
• For older cars with carburetors, consider draining the carburetor bowl after circulating the stabilized fuel to prevent gum buildup in the small jets.

By taking the simple step of adding fuel stabilizer to your fuel tank before storing your car, you can protect your fuel system from the damaging effects of fuel degradation. This small investment can save you significant time and money in the long run by preventing costly repairs and ensuring that your car runs smoothly when you’re ready to drive it again.

From the tires to the engine, taking care of different parts of the car is important when you leave your vehicle sitting idle for a while. But one of the most vital considerations for preserving a car during periods of inactivity is the health of its fuel system.

Fuel, seemingly inert, is actually a complex chemical cocktail that degrades over time, leading to gumming, varnishing, and a host of other fuel-related problems. Next, we will discuss why and how to preserve the fuel system.

Weather’s Impact: Protecting Your Car from the Elements

The environment outside your garage (or lack thereof) plays a significant role in how an infrequently driven car fares. It’s not just about keeping the rain off; different weather conditions pose unique challenges to your vehicle’s well-being. Let’s break down the specific threats and how to mitigate them.

Understanding the Elements: A Weather-Wise Guide

• Heat: Intense sunlight fades paint, cracks dashboards, and degrades rubber and plastic components. The interior can reach oven-like temperatures, accelerating the deterioration of upholstery and electronic devices. Consider a quality car cover, window tinting, or parking in the shade.

• Cold: Freezing temperatures can damage batteries, cause fluids to thicken, and potentially lead to rust. In extreme cold, tire pressure drops, exacerbating the flat-spotting issue we discussed earlier. A battery tender becomes even more crucial in cold climates.

• Humidity: Moisture accelerates rust and corrosion, particularly on exposed metal parts and within the car’s undercarriage. It can also lead to mold and mildew growth inside the cabin. Ensure your car is stored in a well-ventilated area.

• Snow and Salt: Snow itself isn’t the biggest problem, but the salt used to de-ice roads is a car’s worst nightmare. Salt is incredibly corrosive and clings to everything, accelerating rust and damaging paint. If you drive your car in snowy conditions, even occasionally, a thorough undercarriage wash is essential.

Telecommuting and the Infrequently Used Car

The rise of remote work has undeniably changed our driving habits. Many of us are now telecommuting, leading to cars sitting idle for extended periods. This shift necessitates a re-evaluation of traditional maintenance schedules.

• Rethinking Maintenance Intervals: Standard mileage-based maintenance may no longer be relevant. Instead, focus on time-based maintenance. Oil changes, for example, should still be performed at least once a year, regardless of mileage.

• Addressing Infrequent Use Issues: Pay close attention to the issues we’ve already discussed – battery drain, tire flat-spotting, fuel degradation – as they become more pronounced with prolonged inactivity.

• The "Exercise" Drive: Consider taking your car for a longer drive (30-60 minutes) every few weeks. This helps to circulate fluids, recharge the battery, and prevent parts from seizing up. Make sure the engine reaches full operating temperature.

Short Trips vs. Long Trips: A Critical Distinction

Even when you do use your car, the type of trips you take matters. Frequent short trips can be more detrimental than an occasional long journey.

• The Problem with Short Trips: Short trips often don’t allow the engine to reach its optimal operating temperature. This leads to incomplete combustion, resulting in the build-up of condensation and fuel dilution in the engine oil.

• Condensation and Corrosion: Condensation within the exhaust system can also accelerate rust.

• The "Italian Tune-Up": If you primarily use your car for short trips, occasionally taking it for a longer drive at higher speeds (when safe and legal) can help burn off accumulated deposits and moisture. This practice is sometimes jokingly referred to as an "Italian Tune-Up," though it’s best to simply think of it as letting the engine and exhaust system properly reach operating temperature.

Protecting your car from the elements is an ongoing process that requires awareness and proactive measures. Tailor your approach to your specific climate and driving habits. By doing so, you can minimize the negative effects of inactivity and ensure your car remains in top condition, ready to serve you whenever you need it.

Rubber Component Care: Preventing Dry Rot

Your car’s rubber components, often overlooked, are vital for its smooth operation. Belts, hoses, and seals—these seemingly unassuming parts are susceptible to degradation when a vehicle is left idle. The culprit? Dry rot.

Dry rot is the bane of any car left sitting. It leads to cracking, weakening, and eventual failure of these critical components. Imagine a brittle hose bursting and leaving you stranded or a frayed belt snapping, rendering your power steering useless.

These scenarios aren’t just inconvenient. They can lead to costly repairs and even safety hazards. Fortunately, with a bit of preventative care, you can shield your car’s rubber parts from the ravages of time and disuse.

Understanding the Enemy: What is Dry Rot?

Dry rot occurs when rubber components lose their essential oils and moisture. This results in a loss of elasticity and flexibility.

Prolonged exposure to heat, sunlight, and ozone accelerates the process, causing the rubber to harden, crack, and eventually crumble.

Lack of use exacerbates the issue, as the flexing and movement of these components help to keep them pliable.

The Solution: Rubber Protectants to the Rescue

The key to combating dry rot lies in keeping rubber components supple and protected. This is where rubber protectants come in.

These specialized products contain oils and polymers that penetrate the rubber, replenishing lost moisture and creating a protective barrier against environmental factors.

Think of it as a moisturizer for your car’s rubber parts, keeping them healthy and flexible.

Choosing the Right Rubber Protectant

Not all rubber protectants are created equal. Look for products specifically formulated for automotive use and that are safe for various types of rubber.

Avoid protectants that contain petroleum distillates or harsh chemicals, as these can actually damage rubber over time.

A water-based formula is generally a safe bet. Read reviews and choose a reputable brand with a proven track record.

Application: A Simple How-To Guide

Applying rubber protectant is a straightforward process that can be done in a matter of minutes.

1. Clean the surface: Start by cleaning the rubber components with a mild soap and water solution. This removes dirt, grime, and any existing protectant residue.
2. Dry thoroughly: Ensure the surface is completely dry before applying the protectant.
3. Apply protectant: Spray or wipe the protectant onto the rubber component, ensuring even coverage.
4. Wipe off excess: Use a clean cloth to wipe off any excess protectant.
5. Repeat periodically: Reapply the protectant every few months, or as recommended by the product manufacturer.

Vigilant Inspection: Catching Problems Early

In addition to using rubber protectants, regular inspection of your car’s rubber components is crucial.

Visually inspect belts, hoses, and seals for signs of cracking, swelling, leaks, or general deterioration.

Pay close attention to areas exposed to heat, such as engine hoses and belts.

Squeeze hoses to check for softness and flexibility. If they feel hard or brittle, it’s time for a replacement.

If you notice any signs of wear or damage, don’t delay—replace the affected component promptly. A proactive approach can prevent a small problem from escalating into a major repair.

Brake Maintenance: Combating Rust and Corrosion

From the tires to the engine, taking care of different parts of the car is important when you leave your vehicle sitting idle for a while. But one of the most vital considerations for preserving a car during periods of inactivity is the health of its fuel system.

Fuel, seemingly inert, is actually a complex chemical cocktail that degrades over time, leading to potential problems in your vehicle.

When a car sits unused, the brakes—rotors, calipers, and pads—become highly susceptible to rust and corrosion. This can significantly impact their performance and, more importantly, your safety. Addressing this issue proactively is crucial.

The Enemy: Rust and Corrosion

Brake rotors are typically made of cast iron, a material prone to oxidation when exposed to moisture and air.

When a car is parked, especially outdoors or in damp conditions, a layer of rust can quickly form on the rotor surfaces. This rust isn’t just cosmetic; it can lead to uneven braking, reduced stopping power, and even premature wear of the brake pads.

Calipers, responsible for pressing the brake pads against the rotors, can also suffer from corrosion.

The moving parts within the caliper can become seized or sluggish due to rust and debris buildup, hindering their ability to apply even pressure to the brake pads. This will give rise to shuddering, strange noises, and uneven stopping power.

Brake pads, although designed to withstand high temperatures and friction, can also be affected by prolonged inactivity.

Moisture and contaminants can seep into the pad material, causing them to harden or crumble over time.

Solution: Protective Measures for Brake Longevity

Preventative maintenance is key to keeping your braking system in tip-top shape.

Protective Coatings: A Shield Against the Elements

Applying a protective coating, like a rust inhibitor, to the brakes can offer a barrier against moisture and corrosion.

However, it’s imperative to exercise extreme caution and consult with a qualified mechanic before applying any coating to the brake components.

Improper application could compromise braking performance and safety.

A professional can recommend a suitable product and ensure its safe application, focusing on areas prone to rust while avoiding critical friction surfaces.

Regular Inspection and Cleaning: Vigilance is Key

Regular inspection and cleaning can go a long way in preventing serious brake problems.

Visually inspect the rotors, calipers, and pads for signs of rust, corrosion, or damage.

Use a wire brush or brake cleaner to remove loose rust and debris from the rotor surfaces. Be careful not to damage the pads or other components in the process.

If you’re not comfortable performing this task yourself, seek the assistance of a qualified mechanic.

Important Note: Never use oil-based products on braking system components, as they will contaminate the brake pads and severely reduce braking performance.

By taking these preventative measures, you can safeguard your car’s braking system against the damaging effects of inactivity and ensure a safe and reliable driving experience.

Seeking Expert Guidance: When to Consult a Mechanic

From the brakes to the body, caring for a car that’s sitting idle involves a multifaceted approach. But knowing when to hand the reins over to a professional is just as crucial as any DIY maintenance task. While many preventative measures can be taken at home, some issues require the expertise and specialized equipment only a qualified mechanic can provide.

Recognizing the Limits of DIY

It’s tempting to tackle every car problem yourself, especially with the wealth of information available online. And, in some cases, performing all the work yourself might be beneficial.

However, certain repairs demand a level of technical skill and specialized tools that the average car owner simply doesn’t possess. Attempting these repairs without the proper knowledge can lead to further damage, compromise your safety, and ultimately cost you more in the long run.

When to Call in the Professionals

So, how do you know when it’s time to seek professional help? Here are a few key indicators:

Complex Diagnostic Issues

Modern cars are equipped with intricate computer systems that control everything from the engine to the anti-lock brakes. Diagnosing problems within these systems often requires specialized diagnostic tools and software.

If your car is displaying warning lights, exhibiting unusual performance issues (such as rough idling or difficulty starting), or experiencing electrical problems, a mechanic can use diagnostic equipment to pinpoint the root cause of the issue.

Brake System Repairs

While inspecting your brakes for rust and corrosion is a good DIY practice, any actual repair work on the brake system should be left to the professionals. Brakes are a critical safety component, and improper repairs can have devastating consequences.

Replacing brake pads, rotors, or calipers requires specialized knowledge and tools to ensure proper installation and function.

Engine and Transmission Problems

Engine and transmission repairs are among the most complex and technically demanding automotive tasks. These systems are comprised of hundreds of intricate parts that must work together flawlessly.

Attempting to repair these components without the proper expertise can lead to serious damage and costly repairs. If you suspect a problem with your engine or transmission, it’s always best to consult a mechanic.

Any Task That Makes You Uncomfortable

This is perhaps the most important guideline of all. If you’re uncomfortable performing a particular repair or simply don’t feel confident in your abilities, don’t hesitate to seek professional help. Your safety and the well-being of your vehicle are always worth the cost of a mechanic’s services.

The Importance of Following a Maintenance Schedule

Even if your car is sitting idle most of the time, it’s still essential to adhere to a regular maintenance schedule. Car manufacturers provide recommended maintenance schedules in the owner’s manual, outlining when to perform specific services such as oil changes, fluid flushes, and filter replacements.

Why Follow a Schedule for an Idle Car?

Following a maintenance schedule for an infrequently used car might seem counterintuitive. However, fluids can still degrade, rubber components can still dry rot, and corrosion can still occur, even when the car isn’t being driven regularly.

Regular maintenance helps prevent these issues and ensures that your car is ready to perform when you need it.

Tailoring the Schedule

You may need to adjust the maintenance schedule based on your specific driving habits and the amount of time your car sits idle. Discuss your situation with a trusted mechanic, and they can help you tailor a maintenance plan that meets your needs.

They can advise you on how often to perform certain services, even if you’re not putting a lot of miles on your car.

By understanding the limits of DIY repairs and adhering to a regular maintenance schedule, you can ensure that your infrequently driven car remains in good condition for years to come.

So, how often should a car be driven? Ultimately, it depends on your specific situation and car. But, armed with this guide, you should be well-equipped to make the best decision for your vehicle’s health. Happy driving (but not too much, or too little!)!
