Despite better access to information in 2025, many drivers in India still follow outdated car maintenance myths. These myths not only increase running costs but can also shorten vehicle lifespan or cause safety issues. From engine warm-ups to fuel types, let’s bust ten car myths India needs to leave behind this year.
Quick Glance at Common Car Myths India Believes
| Myth | Why It’s Wrong | The Reality |
|---|---|---|
| Idle to warm-up engine | Wastes fuel | Modern engines are ready to go almost instantly |
| Premium fuel = better performance | Not always | Only needed for engines that require it |
| AC reduces mileage drastically | Slightly true | Negligible effect at highway speeds |
| Bigger cars are safer | Not necessarily | Safety ratings matter more than size |
| Regular water for coolant | Dangerous | Only use recommended coolant types |
| All SUVs are off-road capable | Misleading | Many are 2WD and not meant for tough terrains |
| Frequent oil changes are a must | Depends | Follow the manufacturer’s schedule |
| Low tire pressure improves grip | False | It reduces control and fuel efficiency |
| Manual cars are always more fuel-efficient | Not anymore | Many modern automatics are just as efficient |
| Servicing only when issues arise | Costly mistake | Preventive care saves money long-term |
Idle the Engine Before Driving – Still Necessary?
One of the most stubborn car myths in India is the idea that you need to idle your engine for several minutes before driving. This might have been valid decades ago, but not in 2025. Today’s fuel-injected engines are designed to operate efficiently with minimal warm-up. Prolonged idling wastes fuel and increases emissions. For car care facts backed by manufacturers, driving gently for the first few kilometers is far better than idling in your driveway.
Premium Fuel Improves Every Car’s Performance
This is one of the most expensive common auto mistakes car owners make. Premium fuels like 97 or 100 octane petrol are only beneficial for high-performance or turbocharged engines that require them. For a typical hatchback or sedan, using premium fuel will not boost mileage or performance — but it will burn a hole in your wallet. Always check your car’s fuel requirement in the manual.
Driving with AC Ruins Your Mileage
While air conditioning does consume power, its impact on fuel economy is often exaggerated. At city speeds, it might lower mileage slightly, but at highway speeds, the difference is negligible. Rolling down windows at high speed actually increases drag, which can hurt mileage more. Intelligent AC use is part of smart driving, not a car maintenance myth.
Bigger Vehicles = Safer Ride?
Many Indian buyers equate larger cars with superior safety. But this is one of the more misleading car myths India continues to believe. In reality, crash-test ratings, build quality, and features like airbags and electronic stability control play a far more significant role in passenger safety than sheer size. A well-rated compact car is often safer than a poorly built SUV.
Tap Water in the Radiator – Still a Go-To?
It’s 2025, yet some car owners still believe regular water is fine as a coolant substitute. This is not just outdated—it’s dangerous. Tap water lacks the corrosion inhibitors present in proper coolant and can damage engine components over time. Always use the manufacturer-recommended coolant mixture for better heat transfer and engine longevity.
Conclusion
The automotive world has moved forward, but many Indian drivers still cling to outdated ideas. Believing in these car myths India perpetuates leads to poor maintenance choices, higher costs, and safety risks. With accurate information and proper car care facts, drivers can avoid common auto mistakes and get the best out of their vehicles. Ditch the myths—drive smarter in 2025.
FAQs
What’s the most dangerous car myth in India?
One of the most dangerous myths is that bigger cars are automatically safer. This assumption can lead to poor buying decisions. Safety features and crash-test ratings are more important than vehicle size.
Does using premium fuel help in every car?
No, premium fuel only benefits cars that require high octane levels. For regular engines, it offers no noticeable performance or mileage improvement.
Should I still idle my engine in winter?
No. Modern engines don’t need prolonged idling. Driving gently after startup is better for fuel efficiency and engine health.
How often should I change my engine oil?
Refer to your owner’s manual. Most modern cars in 2025 need oil changes every 10,000 to 15,000 km, depending on the oil type and driving conditions.
Can I skip servicing if the car seems fine?
No. Preventive servicing detects problems early, avoids breakdowns, and prolongs the vehicle’s life.
