Petrol vs CNG: Which Is Better for Mileage?
If your main goal is reducing fuel cost and you drive a lot every month, a factory-fitted CNG car can be worth considering. CNG cars generally show their biggest advantage for frequent daily commuting and high annual running.
Petrol cars, however, can be more convenient for buyers who travel outside cities frequently or do not have easy access to CNG stations. Petrol also avoids the need to plan trips around fuel availability.
How to Choose a High-Mileage Car
- Check your monthly running: Higher monthly kilometres can make a fuel-efficient car more valuable.
- Consider CNG availability: Check whether CNG stations are convenient in your area.
- Look beyond claimed mileage: Real-world mileage can be lower than laboratory or certified figures.
- Choose the right size: A smaller car may be more efficient for city use.
- Consider maintenance: Compare service costs and warranty coverage.
- Take a test drive: Mileage is important, but comfort and driving experience matter too.
How Much Can You Save With a High-Mileage Car?
The amount you save depends on how much you drive, the fuel price in your city and the actual mileage of your car. A driver covering a few hundred kilometres per month may see a smaller difference, while a daily commuter covering a large distance can benefit much more from a fuel-efficient or CNG vehicle.
For this reason, buyers should calculate their expected yearly running before choosing a car only on the basis of its advertised mileage.

The Maruti Suzuki Celerio CNG is among the leading factory-fitted CNG cars for claimed mileage, with a published figure of up to 34.43 km/kg.
4. Is CNG cheaper to run than petrol?
CNG can offer a lower running cost per kilometre in many situations, especially for drivers who cover a high number of kilometres. The actual saving depends on local fuel prices and the car's real-world efficiency.
5. Which is the best mileage car for daily city driving?
Maruti Suzuki Celerio, WagonR, Alto K10, S-Presso and Swift are all worth considering for regular city commuting. Your choice should also depend on space, comfort, safety and budget.
6. Does CNG give better mileage than petrol?
CNG vehicles can have strong efficiency when measured in kilometres per kilogram, but km/kg and km/l are different units and should not be directly compared as identical measurements. Running cost should be calculated using the local price of each fuel.
7. Does automatic transmission reduce mileage?
Mileage depends on the engine, transmission technology, driving conditions and variant. Some modern automatic transmissions can deliver good efficiency, so buyers should compare the official mileage figures of the exact variants.
8. Is high mileage more important than engine performance?
Not always. If you mostly drive in the city, fuel efficiency may be a major priority. If you frequently travel on highways or carry passengers and luggage, engine performance, stability and comfort can become equally important.
9. How can I improve my car's mileage?
Maintaining correct tyre pressure, avoiding unnecessary idling, accelerating smoothly, keeping the vehicle serviced and removing unnecessary weight can help improve fuel efficiency. Driving conditions also have a major effect.
10. Should I buy a CNG car only for better mileage?
Not necessarily. Consider your monthly running, availability of CNG stations, boot-space requirements, performance expectations and typical travel routes. Mileage should be one factor in the buying decision rather than the only factor.
