Auto Repair & Maintenance FAQs

If you're not sure what maintenance your car needs, schedule an oil change and get a free multi-point inspection to see what your car needs.Let us help you prioritize what's needed to keep you on the road and your car in good health. We'll take a look and provide zero-pressure recommendations about any special attention your car needs.

Are oil changes every 90 days really necessary?

Standard oil changes are recommended every 3 months or 3,000 miles, whichever comes first. Synthetic oil changes are recommended every 5 months or 5,000 miles, whichever comes first.

Oil degrades with time. It’s essential to consider more than just mileage. Regular oil changes are generally advised every 3 months or 3,000 miles, while synthetic oil requires changing every 5 months or 5,000 miles, depending on which threshold is reached first. Frequent oil changes are vital, even for vehicles that aren’t driven frequently. Changing motor oil every 90 days, regardless of the distance traveled, can significantly extend the life of most vehicles on the road.

What’s in a new vehicle warranty?

Normal wear and tear, often referred to as “wear-out,” is usually not classified as a defect. Components designed for periodic replacement, such as brake pads, filters, and similar items, will inevitably wear out and are generally not included in most dealership warranties. It’s crucial to thoroughly review the specifics of your particular car warranty to understand what is and isn’t covered. Additionally, familiarize yourself with the expected lifespan of these wear-and-tear parts to better anticipate maintenance needs and avoid unexpected costs.

Kelly Blue Book offers valuable resources for evaluating the benefits of purchasing a new car warranty. It’s important to verify whether skipping your 30,000-mile service could potentially void the warranty. Always consult your vehicle’s service manual and warranty agreement to understand the maintenance requirements and how they impact your warranty coverage. Proper maintenance is crucial not only for keeping the warranty valid but also for ensuring the longevity and optimal performance of your vehicle.

How long do tires last?

The lifespan of your tires is a journey, not just a number. Typically, tires can travel between 25,000 to 50,000 miles before they wave the white flag. But remember, this journey varies, influenced by several key factors:

The Type of Tire Matters

Are you riding on high-performance tires? They grip the road with enthusiasm but may wear out faster than their all-season counterparts. Choose the type that aligns with your needs and driving style.

Your Driving Habits Count

If you’re an adrenaline enthusiast, pushing your vehicle to the limits with rapid acceleration and hard cornering, your tires will meet their end sooner. Smooth and steady driving? Your tires will thank you with a longer life.

Where You Drive is Crucial

Smooth highways or rugged trails? Regular encounters with potholes, gravel, or other harsh road conditions will leave their mark on your tires, shortening their lifespan.

Maintenance is Key

Like any good relationship, the one with your tires needs nurturing. Regular rotations, proper inflation, and keeping an eye on alignment can add miles to your tires’ life.

Don’t Ignore the Weather

Just as you dress for the season, your tires react to the weather. Extreme heat or cold can affect their durability. Treat them well, and they’ll return the favor.

Your Vehicle Type and Its Burden

Driving a heavier vehicle or often carrying heavy loads? Your tires feel that extra weight, impacting their wear.

In the end, your tires’ lifespan is a story of where you go, how you get there, and how you care for them along the way. Choose wisely, drive thoughtfully, and maintain regularly for a journey that goes the distance

A good rule of thumb is the higher the tire’s performance rating, the quicker they’ll need to be replaced.

How long does a 30K service inspection take?

A quality 30k service usually takes a day. Our inspections take anywhere  from  from an hour or more depending on the needs of the vehicle and the condition it is in. As soon as your Green Drop Service Advisor has reviewed the inspection report and talked with the technicians, we’ll contact you with an update. During the call, we’ll review with you any concerns and recommendations we have so you can make an informed choice about your car care.

Is the 30,000 mile service worth it?

You may be contemplating whether the 30K mile service is essential, especially if you’re cruising smoothly with few, if any, noticeable issues. However, this routine check is more than just a precaution; it’s an investment in your vehicle’s future. By opting for the 30K mile service, you’re safeguarding your car’s performance and longevity – and ensuring your new car warranty stays valid. This service often includes vital checks and replacements that may seem minor but are crucial for maintaining your vehicle’s health. From oil changes to tire rotations and thorough inspections of brake systems and fluid levels, each aspect of the service plays a key role in preventing potential problems down the road. The 30,000 mile service is a small step today that prevents major setbacks tomorrow, keeping your vehicle running smoothly and keeping you worry-free. Regular maintenance is the key to automotive peace of mind.

Is a 60K service worth it?

Skipping the 60K service might seem like a cost-saving move at first glance, but the financial implications of neglecting this milestone maintenance can be significant. This service interval is crucial as it’s often the first time key components like timing belts and hoses require attention or replacement. These parts are indispensable to your vehicle’s functionality. If not properly maintained, belts and hoses can lead to costly repairs down the line.

The 60K service is a preventive measure to safeguard against the wear and tear that accumulates over tens of thousands of miles. This service typically involves a thorough check and the possible replacement of worn parts. This ensures everything from the engine to the cooling system operates efficiently and reliably. Neglecting this service increases the risk of breakdowns and major mechanical failures, which not only hit the wallet harder but also pose safety risks. Investing in the 60K service is, therefore, an investment in your vehicle’s health, ensuring it continues to perform optimally and saving you from potential future financial strains.

Maintaining the 30/60/90k checkpoint services enables you to get significantly more miles out of your vehicle.

Is 60K considered high mileage?

Building on the evolving perspective of good mileage in used cars, it’s important to highlight the direct link between meticulous maintenance and a vehicle’s resale value. A car that has consistently adhered to its recommended major service intervals, not only runs more reliably, but also stands as a testament to responsible ownership. This diligent care is often documented and can be verified through reports like CARFAX. Upkeep is key factor that can significantly elevate a vehicle’s appeal in the resale market.

When maintenance history is meticulously documented, as done by services like Green Drop with every service, it provides a transparent and trustworthy record of the vehicle’s health and upkeep. This documentation is a powerful tool in the used car market, offering potential buyers clear evidence of the vehicle’s condition and the care it has received. For the seller, this means potentially higher resale values, as buyers are typically willing to pay a premium for a used car with a proven track record of maintenance. For buyers, it offers peace of mind, knowing they are investing in a vehicle that has been well cared for. The commitment to regular, documented maintenance not only preserves the vehicle’s performance and safety but also enhances its financial value in the long term.

How do you determine if 90K recommendations are less expensive than selling my car?

Determining whether adhering to the 90K service recommendations is more cost-effective than selling your car involves a few key considerations:

  1. Compare maintenance costs vs. selling and buying costs: Calculate the estimated cost of the 90K service for your vehicle. This might include replacements of major components, fluids, filters, and labor costs. Compare this with the costs associated with selling your current car (e.g., potential depreciation, selling fees) and purchasing a new or another used vehicle (e.g., down payment, taxes, registration fees, potential financing costs).
  2. Assess the current value of your vehicle: Determine the current market value of your car. Websites like Kelley Blue Book can provide a good estimate. This value, compared with the cost of necessary services, can give you a clearer picture of whether the investment in maintenance is justified.
  3. Consider the longevity and reliability of your car post-service: If the 90K service significantly extends the life of your car and ensures its reliability, it could be more cost-effective in the long run than acquiring a different vehicle, which might bring its own set of maintenance needs and unknowns.
  4. Factor in future depreciation: Every car depreciates, but well-maintained cars tend to hold their value better. If your current car has a good maintenance record, it might depreciate slower post the 90K service, potentially making it a better financial decision to keep it.
  5. Personal circumstances and preferences: Consider your personal needs and preferences. Does your current car still meet your needs in terms of size, function, and performance? Are there new vehicle technologies or features you desire that your current car doesn’t provide
  6. Environmental and hassle factors: Selling and buying a car involves time, effort, and can have environmental impacts. Keeping and maintaining your current vehicle might be less of a hassle and more eco-friendly.

The decision is a balance between the financial aspects (costs of maintaining vs. costs of changing vehicles) and personal factors (needs, preferences, the sentimental value of the car). We can help consult with you to get a detailed understanding of the potential costs and benefits involved.

Regular maintenance and replacement of belts, hoses, and similar parts is why so many cars zoom past the 30k-60k milestone. Well-maintained cars can go many more miles well past 90k. The 90k service has a significant impact on the car’s longevity and resale value.

What do spongy brakes mean?

“Spongy” brakes, often described as a brake pedal that feels soft or less responsive than usual, can indicate several issues within the braking system. This condition means that when you press the brake pedal, it feels unusually easy to push down or goes closer to the floor than normal. Here are some key causes and implications:

  1. Air in the brake lines: This is the most common cause of spongy brakes. The braking system relies on hydraulic fluid to transfer force from the brake pedal to the brake pads. If air gets into the brake lines, it compresses under pressure (unlike fluid), reducing the system’s effectiveness. This can happen due to a leak or if the brake system wasn’t properly bled (air removed) during maintenance.
  2. Low brake fluid: Low levels of brake fluid can lead to inadequate hydraulic pressure in the brake system. This can be due to a leak in the brake line or worn brake pads. When brake pads wear down, the brake caliper pistons extend further, requiring more brake fluid and potentially lowering the fluid level in the reservoir.
  3. Worn brake pads or rotors: Worn pads or rotors can change the distance the caliper piston needs to travel to apply adequate pressure, leading to a spongy feeling. Over time, wear and tear can affect the efficiency of these components.
  4. Faulty master cylinder: The master cylinder is responsible for distributing hydraulic pressure to the brakes. If there’s an internal or external leak, or if the seals inside the cylinder are worn out, it can fail to maintain adequate pressure, leading to a spongy brake feel.
  5. Compromised brake hose: Brake hoses can become soft and begin to expand under pressure as they age, which can lead to a spongy feeling in the brake pedal.
  6. Contaminated brake fluid: Over time, brake fluid can absorb moisture, leading to contamination. This moisture can lower the boiling point of the fluid and introduce air or vapor bubbles into the system, compromising braking efficiency.

It’s important to address spongy brakes immediately, as they can compromise the safety of the vehicle by increasing stopping distances and reducing braking efficiency. A professional mechanic should inspect the vehicle to diagnose the exact cause and perform the necessary repairs or maintenance. Regular brake system inspections and maintenance, including fluid changes and checks for leaks or wear, can help prevent this issue.
