21 car maintenance myths Indian drivers still believe (and what they’re really costing you)

Introduction

“Don’t use the handbrake, it’ll wear out faster.”
“Let your car idle for 10 minutes before driving.”
“Just pour water instead of coolant. It’s the same thing.”

Sound familiar?

In India, car advice comes from all directions. Mechanics, friends, YouTube, even your neighbour who drove an Ambassador once in the 90s. But how much of that advice is actually true?

This blog busts 21 of the most common car maintenance myths Indian drivers still follow and shows you what they could really be costing you.

1. Should I warm up my car for 10 minutes every morning?

Myth: Long idling helps your engine settle in.

Fact: Modern engines are fuel-injected and ready to move in 30 to 60 seconds.

The damage

You’re just wasting fuel and increasing engine wear.

2. Can I drive with the check engine light on?

Myth: If it runs fine, it’s safe.

Fact: It could be a minor or major issue. Ignoring it risks bigger damage.

Tip

Scan the code. Don’t guess.

3. Does idling recharge a weak battery?

Myth: Leaving it on charges it up.

Fact: Idling offers minimal charge. You need a proper drive or external charger.

What to do

Get the battery tested and replaced if necessary.

4. I only need to check tyre pressure when the TPMS light is on

Myth: No warning means pressure is fine.

Fact: Tyre pressure drops over time. TPMS isn't always instant.

Fix

Check manually at least once a month.

5. Are all aftermarket parts bad?

Myth: Only OEM parts are safe.

Fact: Quality aftermarket parts can be as good or better if sourced right.

Pro tip

Buy from reliable sources like Autozilla.

6. Water is enough instead of coolant

Myth: Coolant is optional in Indian climates.

Fact: Water lacks anti-rust and thermal balance. Use proper coolant.

Why it matters

Protects your radiator and engine.

7. AC not cooling? Just refill the gas

Myth: Gas top-up is the fix-all.

Fact: It could be a clogged filter or electrical fault. Diagnose first.

Avoid repeat costs

Get a full system check before refilling.

8. Oil change only every 10,000 km

Myth: All cars follow the 10k rule.

Fact: Driving style and traffic affect oil life. Check your manual.

Better practice

Consider 6,000–8,000 km in heavy traffic cities.

9. Brake noise is okay if car stops

Myth: Squeals are harmless.

Fact: Could indicate worn pads or rotor issues.

Take action

Inspect and replace pads early to avoid extra costs.

10. Cracked windshield is okay if it’s not in view

Myth: It's fine as long as visibility is clear.

Fact: Cracks spread and reduce structural safety.

Solution

Repair or replace early.

11. Premium fuel improves performance for all cars

Myth: More expensive fuel means better mileage and power.

Fact: Only cars designed for high-octane fuel benefit. Others won’t.

Check this

Your owner's manual specifies the correct fuel grade.

12. You should wash your engine regularly

Myth: Clean engines run better.

Fact: Water and pressure can damage electronics and wiring.

Better way

Wipe dust with a cloth. Avoid spraying directly.

13. Topping up oil is the same as changing it

Myth: Just add oil, no need to drain.

Fact: Old oil becomes acidic and loses viscosity. It must be replaced.

Tip

Stick to your service schedule.

14. Using the clutch to slow down saves brakes

Myth: Engine braking is better.

Fact: It wears out your clutch prematurely.

Smarter driving

Use brakes for braking. Let clutch live longer.

15. AC affects engine performance badly

Myth: Car feels sluggish with AC on.

Fact: Yes, it draws power but modern engines handle it efficiently.

Unless...

Your car hesitates abnormally. Then it needs a check-up.

16. Bigger tyres always mean better grip

Myth: Wider is safer.

Fact: It affects mileage, suspension, and steering response.

Always

Follow manufacturer tyre size recommendations.

17. Fuel tank should be run till almost empty

Myth: It’s more efficient to refill only when near empty.

Fact: Low fuel can overheat your fuel pump.

Prevent damage

Refill when quarter tank remains.

18. More expensive oil means better protection

Myth: Higher price = higher quality.

Fact: Use oil that matches your engine specs. Over-spec oils don't add value.

Check this

Look for grade (e.g. 5W30) not price.

19. Car doesn’t need servicing if it runs fine

Myth: No noises = no problems.

Fact: Internal wear isn’t always noisy. Delayed servicing worsens damage.

Follow schedule

Stick to manufacturer intervals even if car feels okay.

20. Low mileage cars don’t need oil changes often

Myth: Oil changes are based only on kilometers.

Fact: Oil degrades with time too — not just usage.

Best practice

Change oil every 6–12 months even if mileage is low.

21. More servicing means better performance

Myth: Servicing frequently improves longevity.

Fact: Over-servicing wastes money and may cause over-torquing, fluid contamination, etc.

Smarter care

Service as recommended, not sooner.
