15 Things You Should Never Do to Your Car (Avoid These Costly Mistakes!) -

Your car is more than just a machine—it’s your daily companion, your travel buddy, and often, a significant investment. But many car owners unknowingly make mistakes that can reduce the lifespan of their vehicles or lead to expensive repairs. Here’s a list of the top 15 things you should never do to your car, whether it’s a manual, automatic, or CVT. Avoiding these can improve performance, save money, and enhance road safety.

1. Ignoring the Check Engine Light

The check engine light is not just a suggestion—it’s your car’s way of telling you something is wrong. Delaying diagnostics can turn a small issue into a big, expensive one.

🛠 Pro Tip: Get an OBD2 scanner or visit a mechanic promptly.

2. Driving with Low Engine Oil

Oil is the lifeblood of your car. Running with low or dirty oil can cause irreversible engine damage.

🛢 Maintenance Tip: Check your oil levels every 2–3 weeks and during long trips.

3. Revving the Engine When Cold

Many drivers rev their engines after starting the car in cold weather. This can stress the engine and reduce its lifespan.

❄️ Why It’s Bad: Cold oil doesn’t lubricate as effectively. Let your engine idle for 30–60 seconds before driving.

4. Riding the Clutch (Manual Transmission)

Keeping your foot on the clutch pedal while driving can lead to premature wear and costly repairs.

👣 Manual Drivers: Use the clutch only when shifting gears—don’t rest your foot on it.

5. Shifting from Reverse to Drive Without Stopping (Automatic)

Quickly switching from reverse to drive (or vice versa) without stopping can damage the transmission system.

⚙️ Transmission Tip: Always bring your car to a full stop before changing gears.

6. Overloading Your Car

Every car has a gross vehicle weight rating (GVWR). Exceeding it can damage the suspension, brakes, and tires.

📦 Reminder: Check your owner’s manual for weight limits—especially before road trips.

7. Neglecting Regular Maintenance

Skipping scheduled services may seem like a money-saver, but it can cause long-term damage.

🧰 Best Practice: Stick to the manufacturer’s recommended service intervals.

8. Using the Wrong Fuel Type

Using lower-grade fuel than recommended can cause engine knocking, reduced performance, and long-term damage.

⛽ Fuel Tip: Always follow your car’s fuel requirements—don’t go cheaper for savings.

9. Driving on Low or Uneven Tire Pressure

Improper tire pressure can lead to blowouts, poor mileage, and uneven wear.

🔧 Air Check: Use a tire pressure gauge monthly or before long drives.

10. Ignoring Unusual Sounds or Vibrations

That weird clicking, squealing, or rattling noise is your car crying for help.

👂 Listen Up: Any unusual sound should be inspected quickly to prevent costly repairs.

11. Resting Hand on Gear Lever (Manual Transmission)

It seems harmless, but resting your hand on the gear shifter can wear down transmission internals.

🤚 Tip: Keep both hands on the wheel when not shifting.

12. Using Water Instead of Coolant

Coolant regulates engine temperature and prevents rust. Using plain water can lead to overheating and corrosion.

🌡️ Coolant Tip: Always use the recommended coolant mix for your vehicle.

13. Washing Your Car Under Direct Sunlight

Washing in sunlight can cause water spots and streaks that damage your paintwork.

☀️ Detailing Tip: Wash early morning or late evening in shade for best results.

14. Delaying Brake Pad Replacement

Ignoring squeaky or worn-out brakes can result in damaged rotors or complete brake failure.

🛑 Brake Check: Inspect your brake pads every 10,000–15,000 km.

15. Using Expired or Cheap Engine Oil and Filters

Low-quality or expired engine oil can clog internal parts and reduce engine efficiency.

🧪 Pro Tip: Invest in high-quality, certified oil and filters—even if slightly more expensive.

✅ Final Thoughts: Treat Your Car Like Family

Taking care of your car isn’t just about avoiding costly repairs—it’s about ensuring safety, better fuel efficiency, and a smoother driving experience. Whether you drive a manual, automatic, or CVT car, these mistakes can harm your vehicle over time.

By avoiding these common car care blunders, you’re investing in a longer-lasting, more reliable vehicle.
