Common Car Maintenance Mistakes to Avoid
Introduction
Owning a car is exciting — but maintaining it properly is what keeps it safe, efficient, and valuable.
Many drivers unintentionally make maintenance mistakes that can cost hundreds (or even thousands) of dirhams later. Whether you drive a luxury SUV in Dubai or a compact sedan in Canada, avoiding these simple errors will keep your car running smoothly for years.
1. Ignoring Regular Oil Changes
Oil is your car’s lifeblood. Skipping oil changes or extending intervals can cause engine wear, overheating, and even total failure.
Expert tip:
- Change your oil every 5,000–8,000 km, depending on your car model and driving conditions.
- Always use the recommended oil grade (found in your owner’s manual).
Example:
A 2021 Toyota Corolla that misses two consecutive oil changes may experience up to 30% reduced engine efficiency over time.
2. Forgetting Tire Maintenance
Tires affect everything — safety, fuel efficiency, and ride comfort. Yet many drivers forget to check them.
Common mistakes:
- Driving with underinflated tires
- Skipping rotation every 10,000 km
- Ignoring wheel alignment
| Tire Issue | Effect on Car | Preventive Action |
|---|---|---|
| Low pressure | Increases fuel use by up to 10% | Check pressure monthly |
| Uneven wear | Reduces tire life | Rotate every 10,000 km |
| Misalignment | Causes vibration, steering issues | Align every 6 months |
3. Neglecting Brake Inspection
Your brakes keep you safe. Worn brake pads or low brake fluid can lead to serious accidents.
Warning signs:
- Squeaking or grinding noise
- Vibrations when braking
- Increased stopping distance
Action: Have your brake pads and rotors checked every 20,000 km or if you notice any unusual sound or feel.
4. Ignoring the Check Engine Light
That glowing light on your dashboard isn’t decoration!
Ignoring it could hide problems with your oxygen sensor, catalytic converter, or fuel system — all costly to fix later.
Quick advice:
Use a diagnostic tool or visit a trusted service center as soon as the light appears.
5. Not Replacing Filters on Time
Filters (oil, air, cabin, and fuel) protect both you and your engine.
| Filter Type | Purpose | When to Replace |
|---|---|---|
| Oil filter | Keeps engine oil clean | Every oil change |
| Air filter | Improves engine performance | Every 15,000–20,000 km |
| Cabin filter | Cleans air inside cabin | Every 15,000 km |
| Fuel filter | Keeps fuel system clean | Every 30,000–40,000 km |
6. Using the Wrong Fluids
Mixing or using low-quality fluids can damage your car’s transmission, brakes, or cooling system.
Examples of mistakes:
- Adding tap water instead of coolant
- Using non-compatible brake fluid
- Ignoring windshield washer fluid levels
Pro tip: Always use fluids approved by your car manufacturer and store small backup bottles in your trunk.
7. Overlooking Battery Care
Batteries typically last 3–5 years, but high heat or corrosion can shorten that lifespan.
Avoid these:
- Letting your car sit unused for weeks
- Forgetting to clean battery terminals
- Ignoring slow cranking starts
Simple fix:
Check your battery voltage monthly and keep terminals clean and tight.
8. Skipping Regular Washes and Waxing
Dirt, salt, and sand can eat away at your car’s paint and underbody — especially in coastal or desert climates.
Expert advice:
- Wash your car at least once every two weeks.
- Apply wax every 3 months to protect against UV and corrosion.
In Dubai’s dusty environment, frequent washing helps prevent paint oxidation and sensor blockage in modern vehicles.
