5 Common Mistakes Car Owners Make During Maintenance

Proper car maintenance keeps your vehicle safe, efficient, and long-lasting.
Yet, many car owners unintentionally make mistakes that shorten their car’s lifespan and cost them thousands in repairs.
Here are the 5 most common mistakes you should avoid — and how Car Doctor Limited can help.

5 Common Mistakes Car Owners Make During Maintenance

1# Skipping Regular Oil Changes

Your engine oil keeps everything running smoothly by reducing friction and heat.
Ignoring oil changes is the fastest way to destroy an engine.

• Recommended: Change oil every 5,000–7,000 km (depending on vehicle type and oil quality).

• Skipping one oil change can increase internal wear by up to 30%.

At Car Doctor, we use manufacturer-recommended oils and check oil filters during every service — ensuring the engine runs at peak performance.

2# Using Tap Water Instead of Coolant

Many drivers think water is fine for cooling, but it’s not!

Tap water causes rust, corrosion, and overheating over time.

Always use the proper coolant mix (50% antifreeze + 50% water) to keep engine temperature stable and prevent internal rusting. Our technicians check coolant color, level, and quality every visit — because prevention is cheaper than repair.

3# Ignoring Brake Fluid and Brake Pads

Brakes save lives, but many owners forget they need regular checks.
Old brake fluid absorbs moisture, reducing braking power.
Worn-out brake pads can damage the brake rotor — a much costlier replacement.

• Brake fluid should be replaced every 12–18 months.
• Brake pads usually last 20,000–30,000 km, depending on driving habits.

At Car Doctor Limited, we inspect both during each maintenance visit.

4# Neglecting Tire Pressure and Wheel Alignment

Incorrect tire pressure affects safety, comfort, and fuel economy.
Too low — you burn more fuel.
Too high — you lose traction and control.

Wheel alignment issues cause uneven tire wear and steering problems.

Proper pressure + regular alignment = up to 15% better mileage and 30% longer tire life. Our computerized wheel alignment system ensures your car stays stable, safe, and efficient.

5# Delaying Filter Replacements

Air, oil, and fuel filters protect your engine from dirt and impurities. A clogged filter forces the engine to work harder — increasing fuel use and reducing power.

It’s a simple and inexpensive fix most people forget.

Change your air filter every 10,000–15,000 km and fuel filter every 20,000 km for best results.
